Female education - The Impact of Women's Education on Society, Violence Against Women in Society and Women's Empowerment.

The Impact of Women's Education on Society

Women's education is a broad term encompassing numerous complex issues and debates surrounding the schooling of girls and women—specifically within primary, secondary, and higher education, as well as health education. It is often referred to simply as "girls' education" or "women's education." This field covers subjects such as gender equality and access to education. The education of women and girls is crucial for poverty reduction. Broader topics associated with this field include "single-sex education" and "religious education" for women—contexts in which education is segregated based on gender.

Disparities in the education of girls and women are quite complex: women and girls face direct barriers to school enrollment—such as violence against women or prohibitions on girls attending school—while other challenges are more systemic and subtle. For instance, disparities in Science, Technology, Engineering, and Mathematics (STEM) education remain deeply entrenched, even in regions like Europe and North America. In some Western nations, women have surpassed men at various levels of education. For example, during the 2020–2021 academic year in the United States, women earned 63% of associate degrees, 58% of bachelor's degrees, 62% of master's degrees, and 56% of doctoral degrees.

Improving girls' educational attainment has a profound impact on the health and economic prospects of young women; in turn, this also enhances the prospects of their entire communities. Children whose mothers have received a primary education experience an infant mortality rate that is half that of children whose mothers are illiterate. In the world's poorest nations, 50% of girls do not attend secondary school. Nevertheless, research indicates that every additional year of schooling for girls increases their lifetime earnings by 15%. Improving women's education—and thereby enhancing their earning potential—leads to an improvement in the standard of living of their own children, as women spend a larger portion of their income on their families, whereas men do so to a lesser extent. Nevertheless, numerous barriers to girls' education still persist. In some African countries, such as Burkina Faso, girls are unable to attend school; a very fundamental reason for this is the lack of separate toilet facilities for girls.

Education improves the health and level of health awareness of a woman, her partner, and her family. Enhancing women's educational attainment and providing them with advanced training also helps in delaying the onset of sexual activity, raising the age of first marriage, and delaying the birth of the first child. Furthermore, higher levels of education increase the likelihood of women remaining unmarried, remaining childless, or living without formal marriage, while simultaneously increasing the prevalence of long-term partnerships. Research has established a correlation between women's access to education and career opportunities, and their adoption of altered life plans. In some communities, cultural traditions that emphasize traditional gender roles continue to act as barriers to women's access to education. Women's education is also crucial for their health; it increases the use of contraceptives, reduces the incidence of sexually transmitted infections, and expands the resources available to women who are divorced or facing domestic violence. Education also improves women's communication with their partners and employers, while simultaneously boosting their rates of civic participation.

Given the far-reaching social impacts of women's education, 'Sustainable Development Goal 4' (SDG 4)—"Quality Education for All"—places special emphasis on addressing inequalities in women's education; it is also deeply intertwined with 'Sustainable Development Goal 5' (SDG 5)—"Gender Equality." In developing countries, girls' education (and women's empowerment in general) accelerates the pace of development and leads to a rapid decline in population growth rates; thus, it plays a pivotal role in resolving environmental challenges, such as mitigating climate change. 'Project Drawdown' estimates that educating girls is the sixth most effective measure against climate change—ranking even higher than solar power plants and nuclear energy.

Violence Against Women in Society

Between 1900 and 1940, violence against female teachers in Sweden emerged as a significant political issue. By 1900, 66 percent of Sweden's teachers were women—many of whom worked in remote rural areas, where they faced the dual challenges of isolation and the threat of violence from men. Politicians, academics, and female writers debated various measures to mitigate these risks, such as providing teachers with guard dogs, weapons, and telephones.

                                                                                    

In Pakistan, a negative correlation was observed between the level of formal education attained by a woman and the likelihood of her experiencing violence (After, 2013). The researcher employed "snowball convenient sampling"—a sampling method in which participants are referred to one another. Due to ethical and privacy concerns, this proved to be the most practical approach for the researcher. An "informant" played a crucial role in data collection, the details of which were subsequently cross-checked. This sample of women who had experienced violence comprised married women aged 18 to 60, drawn from both rural and urban communities. This study describes the various forms of physical violence that are prevalent, thereby shedding light on the circumstances that women endure—regardless of their community background (rural or urban). In the context of this study, education was underscored as the sole solution—and an absolute necessity—for eradicating violence at its roots. In this regard, it is also essential to overcome existing political and social barriers.

This relationship is far more complex than it appears, for even if women are uneducated, they can still become empowered (Marrs Fechtel, 2014). Immigrant Latin American Women (ILW) participated in a qualitative study involving groups of 8 to 10 individuals at a time; they completed an 11-week program that focused primarily on self-esteem, awareness regarding domestic violence, and healthy relationships. Immigrant Latin American Women (ILW) constitute a demographic group that is disproportionately affected by domestic violence. Although this program took place outside a traditional classroom setting, it nonetheless emphasized dialogue, critical thinking, and emotional well-being—areas that ideally should be cultivated during an individual's formative school years. Ultimately, despite the fact that many of these women were uneducated, they emerged with a heightened sense of control over their lives—a vital life skill.

Across different nations, violence against women and girls manifests in various forms. In Nigeria, UNICEF has documented 16 key facts associated with such incidents. Some of these facts include: physical and psychological repercussions; short-term and long-term consequences; and the impact on victims, children, and society as a whole. Furthermore, certain specific factors perpetuate violence against women in this region—such as the lack of educational opportunities for women—a critical issue that warrants open and public discourse. Genuine development is attainable only when individuals adopt positive habits that serve to protect them from violence. In the 1980s, Zambia implemented universal schooling across all educational levels.

Women's Empowerment

Education systems vary in terms of administration, curriculum, and staffing; nevertheless, they all exert an influence on the students they serve. As women have gained rights, formal education has emerged as a symbol of progress and a crucial step toward achieving gender equality. To attain true gender equality, a holistic approach is essential. Diverse contexts present distinct challenges, necessitating tailored solutions. Nevertheless, focusing on women's empowerment within education systems worldwide has proven to be a successful strategy. Discussions surrounding "Girl Power" and women's education—often framed as the primary solutions for eradicating violence against women and economic dependence on men—can sometimes become so dominant that they overshadow the nuanced understanding of how context, history, and other factors truly impact women (Shelina Zahra Jan Mohamed, 2015). For instance, when former Secretary of State Hillary Clinton drew parallels between the tragedy involving Malala Yousafzai in Pakistan and the abduction of girls in Chibok, Nigeria—thereby centering girls' education as the pivotal issue—history and context were effectively sidelined. The shooting of Malala was reduced solely to her personal quest for education as a young girl; this discourse failed to address critical underlying issues such as U.S. intervention, poverty, government corruption, and political instability.

Education systems and schools play a pivotal role in fostering girls' interest in various disciplines, including STEM fields. By providing equal opportunities to access and benefit from high-quality STEM education, these institutions can make a significant contribution to women's empowerment. In Bangladesh, the government has implemented several programs aimed at increasing female literacy rates. These initiatives include distributing free textbooks to all primary school students, providing free education to girls up to the university level, and offering stipends to girls enrolled in rural secondary schools.

Gender equality entails more than merely ensuring access to schooling; the curriculum also plays a pivotal role in this regard. Schools need to focus on boosting girls' self-confidence and fostering their capacity to participate equally in society. The pedagogical methods adopted by teachers in the classroom are crucial in shaping women's empowerment and gender equality. In successful projects implemented in Peru and Malawi, teachers were trained using "Teaching Guides" specifically designed for gender-sensitive instruction. These "Teacher Guides" were developed by Peru's "Vision Area Network" and Malawi's "Girls Empowerment Network." Both organizations received grants from "Women Strong International." These projects produce guides and training programs for teachers, enabling them to foster gender sensitivity in the classroom and assist girls in recognizing and realizing their full potential.

 

Medical education - General Techniques and Evidence Base, Entry-level medical education programs, Postgraduate Education for Medical Students.

What is medical education?

Medical education is the education concerned with the practice of becoming a medical professional; it encompasses the initial training required to become a doctor (i.e., medical school and internship) as well as subsequent additional training (such as residency, fellowships, and continuing medical education).

Medical education and training vary significantly across the globe. Various teaching methods have been employed in medical education, which constitutes an active field of educational research.

Medical education—at all levels, including entry-level, postgraduate, and continuing medical education—also serves as an academic discipline dedicated to the education of medical doctors. Before advancing through the various stages of medical education, it is mandatory to fulfill certain specific requirements, such as demonstrating "Entrust able Professional Activities."

General Techniques and Evidence Base

In medical education, teaching principles are applied specifically within the context of medical training. Medical education has been a pioneer in the field of evidence-based education; this distinction is attributed to the development of evidence syntheses—such as "Best Evidence Medical Education," formulated in 1999—which aimed to "shift from opinion-based education toward evidence-based education." Common evidence-based techniques include the "Objective Structured Clinical Examination" (OSCE) for assessing clinical skills, and reliable, checklist-based assessments designed to evaluate the development of "soft skills"—such as professionalism. However, some ineffective teaching methodologies still persist in medical education, such as tailoring instruction to individual learning styles and Edgar Dale's "Cone of Learning."

Entry-level medical education programs

Entry-level medical education programs are tertiary-level courses conducted within medical schools. Depending on the jurisdiction and the university, these may be either undergraduate-entry (primarily in Europe, Asia, South America, and Oceania) or graduate-entry programs (primarily in Australia, the Philippines, and North America). Some jurisdictions and universities offer both types of programs—undergraduate-entry and graduate-entry—(such as Australia and South Korea).

Typically, initial training is provided within the medical school itself. Traditionally, entry-level medical education is divided into pre-clinical and clinical studies. The former encompasses basic sciences, such as anatomy, physiology, biochemistry, pharmacology, pathology, and microbiology. The latter involves the study of various fields of clinical medicine, including internal medicine, pediatrics, obstetrics and gynecology, psychiatry, general practice, and surgery. In recent times, significant efforts have been made in the United States to incorporate Health Systems Science as a "third pillar" of medical education, taught alongside pre-clinical and clinical studies. HSS provides a foundational platform and framework for understanding and learning how patient care is delivered, how health professionals collaborate to provide that care, and how health systems can be improved to enhance patient care and health services.

The Liaison Committee on Medical Education (LCME) is the accrediting body for medical schools granting MD degrees in the United States and Canada. To maintain accreditation, medical schools must ensure that students meet a specific set of standards and competencies established by the accrediting committees. "Functions and Structure of a Medical School" is a document published annually by the LCME that defines 12 standards for accreditation.

The Association of American Medical Colleges (AAMC) has recommended thirteen "Entrust able Professional Activities" (EPAs) that medical students are expected to master before beginning a residency program. EPAs are based on integrated core competencies developed during medical school training. Each EPA outlines its key characteristics, associated competencies, and a list of observable behaviors required to perform that activity. Students progress through various levels of understanding and proficiency; as their competence grows, their need for direct supervision diminishes. Ultimately, students should be capable of performing each activity independently, requiring assistance only when a situation is unique or unusually complex.

Medical education has faced criticism due to a lack of innovation and its excessive duration, which places an increased financial burden on students. There has been a significant rise in the number of programs that integrate medical training with research (M.D./Ph.D.) or management studies (M.D./MBA); however, this approach has also drawn criticism, as it has been observed that prolonged interruptions in clinical training ultimately have an adverse effect on clinical knowledge.

Postgraduate Education for Medical Students

Upon completion of entry-level training, newly graduated physicians are often required to practice under supervision for a prescribed period—typically one year—before receiving full licensure; this period may be referred to as an "internship," "provisional registration," or "residency."

                                                                                 

  

Further training in a specific field of medicine may also be pursued. In the U.S., specialized training undertaken after residency is termed a "fellowship." In some jurisdictions, this specialized training commences immediately upon the completion of entry-level training, whereas in others, junior physicians must undergo several years of general (unspecialized) training before embarking on a specialization.

Every residency and fellowship program is accredited by the Accreditation Council for Graduate Medical Education (ACGME). This physician-led, non-profit organization is dedicated to enhancing the quality of medical education. The ACGME oversees all M.D. and D.O. residency programs within the United States. As of 2019, there were approximately 11,700 ACGME-accredited residency and fellowship programs, spanning 181 specializations and sub-specializations.

Pedagogy itself is also becoming an increasingly integral component of postgraduate medical training. It is now becoming common for medical educators to acquire formal qualifications in the field of education; this trend has led to a rapid proliferation in the number of graduate programs available in medical education.

Continuing medical education course

In most countries, completing 'Continuing Medical Education' (CME) courses is a mandatory requirement for maintaining one's professional license. CME requirements vary significantly depending on the specific state or country. In the United States, the accreditation process is overseen by the 'Accreditation Council for Continuing Medical Education' (ACCME). To fulfill these requirements, physicians often participate in specialized lectures, grand rounds, conferences, and performance-improvement activities. Furthermore, for their professional advancement, physicians are increasingly opting to pursue additional graduate-level training through formal medical education programs.

The Importance of Online Teaching in Medical Education

The use of online teaching in medical education is expanding rapidly, typically facilitated through Learning Management Systems (LMSs) or Virtual Learning Environments (VLEs). Furthermore, many medical schools have adopted 'blended learning,' which combines videos, asynchronous activities, and face-to-face exercises. A significant review published in 2018 revealed that online teaching methods are gaining rapid popularity in medical education, leading to increased student satisfaction and improved performance in knowledge assessments. However, evidence-based multimedia design principles are rarely applied when creating online lectures, despite their proven effectiveness for medical students. To introduce an element of novelty into the online teaching environment, 'serious games'—the benefits of which have previously been observed in medical education—can be utilized to break the monotony of online lectures.

Areas of research in online medical education include practical applications, such as the use of simulated patients and virtual medical records (see also: Telehealth). When compared in non-intervention settings, simulation-based training in medical education demonstrates a positive impact on knowledge, skills, and behavior, and a moderate impact on patient outcomes. However, compared to traditional face-to-face lectures, data regarding the effectiveness of asynchronous online learning remains inconsistent. Moreover, studies utilizing modern visualization technologies—specifically Virtual and Augmented Reality—have shown great promise as a means of enhancing instructional content in the teaching of physiology and anatomy. 

Music education - Overview of Music Education, Teaching Strategies for Music Education, Major International Methods of Music Education.

 

What is music education?

Music education is a practical field in which teachers are trained to pursue careers as primary or secondary music teachers, or as ensemble directors in schools or music institutions. Music education is also a research discipline in which scholars conduct original research on the methods of teaching and learning music. Scholars of music education publish their findings in peer-reviewed journals and teach undergraduate and graduate students—who are training to become music teachers—enrolled in university schools of education or music.

Music education touches upon all domains of learning, including the psychomotor domain (skill development), the cognitive domain (knowledge acquisition), and, notably, the affective domain (the learner's willingness to receive, internalize, and share what has been learned), which encompasses musical appreciation and sensitivity. Many music education curricula incorporate the use of mathematical skills, as well as the intuitive use and understanding of a second language or culture. Consistent practice of these skills benefits students in numerous other academic subjects and also improves their performance on standardized tests such as the ACT and SAT. Music instruction is a common feature ranging from preschool through upper-secondary education, as engagement with music is considered a fundamental component of human culture and behavior. Cultures worldwide hold diverse perspectives on music education, largely due to their distinct histories and political contexts. Studies suggest that teaching music from other cultures can help students understand unfamiliar sounds more intuitively; these studies also indicate that musical preferences are linked to the language spoken by the listener and the other sounds they encounter within their own culture.

During the 20th century, several distinct approaches to music instruction were developed or further refined, some of which have had a profound and widespread impact. The DeCroce Method (Eurhythmics) was developed in the early 20th century by the Swiss composer and educator Émile Jaques-Dalcroze. The Kodaly Method emphasizes the benefits of physical instruction and responsiveness to music. The Orff Schulwerk approach to music education encourages students to develop their musical abilities in a manner that parallels the historical development of Western music.

The Suzuki Method creates a musical learning environment that mirrors the environment in which an individual acquires their native language. Gordon's Music Learning Theory provides music educators with a method for teaching musical skills through "audiation"—a concept Gordon defined as hearing music with understanding in one's mind. "Conversational Solfège" fully immerses students in the musical literature of their own culture—in this instance, American culture. The "Karabo-Cone Method" utilizes props, costumes, and toys to teach children fundamental musical concepts, such as the musical staff, note duration, and the piano keyboard. The tangible environment of specially designed classrooms facilitates a child's acquisition of musical fundamentals through tactile exploration. The objective of the MMCP (Manhattanville Music Curriculum Project) is to shape perspectives, thereby helping students perceive music as something personal, contemporary, and constantly evolving. "Popular Music Pedagogy" entails the systematic teaching and learning of rock music and other forms of popular music, whether within or outside the formal classroom setting. Some believe that specific types of musical activities can assist a child in gaining greater control over their breath, body, and voice.

Overview of Music Education

In primary schools across European countries, children often learn to play musical instruments such as keyboards or recorders, sing in small groups, and learn about the elements and history of music. In countries like India, schools typically utilize the harmonium, although instruments such as keyboards and violins are also quite popular. Students are generally taught the fundamentals of Indian Raga music. In primary and secondary schools, students often have the opportunity to perform in various musical ensembles—such as choirs, orchestras, or school bands (including concert bands, marching bands, or jazz bands). In some secondary schools, additional music classes may also be available. At the junior high school level, or its equivalent, music generally remains an integral part of the curriculum.

At the university level, students enrolled in most Arts and Humanities programs earn academic credits for music courses—such as Music History (which typically focuses on Western art music) or Music Appreciation (which centers on active listening and learning about various musical genres). Furthermore, most North American and European universities offer musical ensembles—such as choirs, concert bands, marching bands, or orchestras—that are open to students majoring in various disciplines. Most universities also offer degree programs in music education, which certify students to work as music teachers at the primary and secondary levels. Advanced degrees, such as a D.M.A. or Ph.D., can lead to employment opportunities within universities. These degrees are awarded upon the completion of coursework related to music theory, music history, pedagogical techniques, private instruction on a specific instrument, participation in musical ensembles, and in-depth observation of experienced educators. Music education departments at North American and European universities also support interdisciplinary research in fields such as music psychology, the historiography of music education, educational ethnomusicology, communicology, and the philosophy of education.

Outside of North America and Europe, the study of Western art music is becoming increasingly common within the field of music education, including in Asian countries such as South Korea, Japan, and China. Concurrently, Western universities and colleges are expanding their curricula to incorporate music from beyond the scope of Western art music; this includes music from West Africa, Indonesia (such as Gamelan), Mexico (such as Mariachi), and Zimbabwe (Marimba), as well as popular music.

Music education is provided on an individual basis, as a lifelong learning process, and within community contexts. Both amateur and professional musicians typically take music lessons—that is, they learn music through small, private sessions with an instructor.

Teaching Strategies for Music Education

Although teaching strategies are determined by the music teacher and the music curriculum specific to their field, many teachers rely heavily on one of the various teaching methods that emerged in recent generations and developed rapidly during the latter half of the 20th century. These methods emphasize active learning by blending approaches derived from both traditional and contemporary educational theories, as they advocate for student-centered instruction facilitated through creative activities.

Major International Methods of Music Education

DeCroce method

The DeCroce Method was developed in the early 20th century by the Swiss composer and educator Émile Jaques-Dalcroze. This method is divided into three fundamental concepts: the use of solfège, improvisation, and eurhythmics. Sometimes referred to as "rhythmic gymnastics," eurhythmics teaches concepts of rhythm, structure, and musical expression through the use of movement; this is the concept for which DeCroce is best known. It emphasizes that students should acquire a physical awareness and experience of music through training that activates all their senses—particularly their kinesthetic (movement-sensing) senses. According to the DeCroce Method, music is the fundamental language of the human brain and, therefore, is deeply intertwined with our very existence. American proponents of the DeCroce Method include Ruth Apperson, Anne Farber, Herb Henke, Virginia Mead, Lisa Parker, Martha Sanchez, and Julia Schonely-Black. Many active teachers of the DeCroce Method were trained by Dr. Hilda Schuster, who was herself a student of DeCroce.

Kodaly method

Zoltán Kodaly (1882–1967) was a renowned Hungarian music educator, philosopher, and composer who emphasized the benefits of sensory perception, physical instruction, and active engagement with music. Fundamentally, this is not merely a teaching method; rather, it constitutes an entirely new system of musical literacy and training. This system posits that music education should commence in early childhood—much in the same way we acquire our native language. Within this framework, music is regarded as an educational medium capable of fostering social change. Furthermore, the system asserts that every individual possesses the innate capacity to connect with music through their senses, their voice, and their physical movements. His pedagogical principles are grounded in a creative and joyful educational framework, the foundation of which rests upon a profound understanding of the senses of hearing and sight, intuition, and physical movement. Thus, this framework establishes a foundation for listening, expressing emotions through music, reading, writing, and comprehending music theory. This process unfolds in several stages. It involves teaching patterns of rhythm, melody, and pitch through songs, alongside practicing the skills of listening to, echoing (vocally), articulating, identifying, reading, writing, creatively utilizing, and theoretically understanding all the constituent elements of music. Kodaly's primary objective was to instill in his students a lifelong love for music. He firmly believed that it was the duty of the school system to make this vital aspect of education accessible to children. The principal tools employed in Kodaly's teaching methodology include the use of hand signs (or 'sol-fa'), rhythmic syllables (known as 'stick notation'), and 'Movable Do' (i.e., vocal practice). Most importantly, this pedagogical approach is universally accessible, thereby ensuring that music remains within the reach of every individual. Most countries have developed their teaching methodologies based on their own folk or community music traditions; however, in the United States, the Hungarian method is predominantly utilized. It is a result of the efforts of Denise Bacon, Katina S. Daniel, John Feyerabendian, Jean Spinor, Jill Trinka, and others that Kodaly's ideas have emerged at the forefront of music education in the United States.

Orff Schulwerk

Carl Orff was a renowned German composer. The "Orff-Schulwerk" is regarded as an "approach" to music education. It begins with the student's innate abilities, through which they are able to engage with elementary forms of music by utilizing basic rhythms and melodies. Orff views the entire body as a percussive instrument, and students are encouraged to develop their musical capabilities in a manner that parallels the historical evolution of Western music. This approach fosters a sense of self-discovery among students, encourages improvisation, and discourages pressure imposed by adults as well as rote, mechanical exercises. Carl Orff devised a specialized set of instruments—comprising modified versions of glockenspiels, xylophones, metallophones, drums, and other percussion instruments—specifically designed to meet the requirements of the "Schulwerk" curriculum. Each bar of these instruments is removable, making it possible to construct various musical scales. Orff's instruments aid in the development of visual and kinesthetic motor skills in young children—skills that, in these children, may not yet be sufficiently developed to play other musical instruments. Experts who have shaped the American adaptation of the Orff approach include Jane Frazee, Armida Steen, and Judith Thomas.

Suzuki method

The Suzuki Method was developed in Japan shortly after World War II by Shinichi Suzuki, and it utilizes music education to enrich the lives and moral character of its students. This movement is grounded in two core beliefs: first, that "all children can be given a good music education"; and second, that learning to play music at a high level involves cultivating certain character traits or virtues that further beautify an individual's soul. The primary method for achieving this centers on creating a learning environment for music that precisely mirrors the experience one undergoes while acquiring one's native language. This "ideal" environment encompasses love, high-quality examples, praise, rote learning and repetition, as well as a curriculum tailored to align with the student's developmental readiness to master specific techniques. Although the Suzuki Method enjoys considerable international popularity, its influence within Japan remains less significant compared to that of the Yamaha Method—a system established by Genichi Kawakami in collaboration with the Yamaha Music Foundation.

Human rights education - The Objective of Human Rights Education, Progressing development, Education and Models

The Objective of Human Rights Education

Human rights education is a learning process aimed at fostering knowledge, values, and skills regarding the rights to which every individual is entitled. This form of education teaches students to view their experiences through a lens that enables them to integrate these concepts into their personal values, decision-making processes, and everyday situations. According to Amnesty International, human rights education serves as a tool for empowerment by training individuals, thereby equipping them with the skills and behaviors necessary to promote dignity and equality within their communities, societies, and the wider world.

The "National Economic and Social Rights Initiative" has emphasized the paramount importance of non-discrimination within the context of human rights education. Governments must ensure that the provision of such education remains free from any form of bias—whether based on race, gender, religion, language, national or social origin, political or personal opinion, birth, or any other status. All students, parents, and communities possess the right to participate in decisions affecting their respective schools, just as they themselves are entitled to the right to education.

History

The "Universal Declaration of Human Rights" states that fundamental human rights require protection, and on this basis, every individual is entitled to certain basic rights and freedoms.

In collaboration with 'Education for International Understanding' and 'United Nations Academic Impact,' the Asia-Pacific Centre organized the 2018 'United Nations Global Citizenship Education Seminar' at the United Nations Headquarters in New York City. These seminars help advance human rights education by bringing people together on a shared platform, thereby fostering the development of new ideas and concepts to strengthen this movement. Proponents of human rights education believe it is of paramount importance, as it provides and disseminates knowledge regarding terminology related to human rights; furthermore, it empowers students to adopt a critical perspective toward human rights.

Progressing development

The Office of the High Commissioner for Human Rights continues to promote human rights education—a task it undertakes within the framework of its technical cooperation programs and through the 'ACT Project'; this project provides financial assistance to grassroots-level initiatives and supports national and local endeavors dedicated to human rights education. The ACT, or 'Assisting Communities Together' Project, is a collaborative effort between the OHCHR and the United Nations Development Programme (UNDP). Its objective is to support civil society organizations that are conducting human rights-related activities within local communities. The OHCHR also serves as the coordinator for the 'World Programme for Human Rights Education.' This is a more flexible program, distinct from other initiatives designed to span decades; it focuses on a different thematic issue every few years and seeks to strengthen human rights education through diverse approaches.

Education

The OHCHR has developed training materials and resource tools for human rights education.

Human Rights Education is now also being increasingly incorporated into school curricula. For instance, human rights training has been integrated into relevant subjects such as history, politics, and civics; furthermore, specialized courses are being made available to high school students under the 'International Baccalaureate Diploma' program.

Several cities around the world have even enacted legislation to successfully promote human rights education within their public schools; an example of this is the 'Municipal Plan for Human Rights Education' in the Brazilian city of Sao Paulo.

Models

1. Four models have emerged to assist in classifying human rights education within both formal and informal educational spheres: Values ​​and Awareness, Accountability, Transformative, and Socio-economic-ethical. To help steer human rights education in the right direction, these models have defined the "goals, target groups, and other practical elements—such as subject matter and methodology—of educational programs."

2. Accountability: The Accountability model approaches human rights from a legal and political perspective, targeting learners who are already engaged with the subject through their professional roles. This model is implemented through training and networking, covering topics such as court cases, codes of conduct, and strategies for engaging with the media. This model is "linked to the individual and their professional role" and is "oriented toward integrating human rights education into the training of government employees, thereby helping to ensure that they uphold human rights while discharging their responsibilities."

3. Transformative: This educational model focuses on the psychological and sociological aspects of human rights. The groups for whom this model is effective include vulnerable populations and individuals who have personal experiences of being affected by this subject—such as women and minorities. The objective of this model is to empower the individual, particularly victims of abuse and trauma. While this model works toward recognizing human rights violations, it is also committed to preventing such violations. The Transformative model "emphasizes empowering disadvantaged groups to organize collectively—not only to advance human rights activism but also to bring about broader social change." It can be more accurately described as "promoting the goal of social change," encompassing both "activism" (which includes collective action and community development) and taking individual action to mitigate violations within one's personal life and immediate environment.

4. The Socio-Ecological-Ethical Model of Human Rights Education: Munir Musa Sadr Uddin has developed a model for teaching human rights. This three-dimensional model interweaves social, ecological, and ethical (ethics and critical thinking) elements; these elements interact dialectically with one another to foster resilience and support HRE (Human Rights Education) practices. Recognizing the importance of socio-cultural structures and self-realization is paramount to adopting and upholding shared rights. Similarly, cultivating an ecological identity through various narratives (stories) offers profound insight into one's personal identity and its interconnections with the social, cultural, political, and economic environment. In this context, ethics serves as a personal discipline of critical self-discovery. Although personal values ​​evolve through experience and engagement with one's environment, they are nonetheless often deeply embedded within social and relational identities. Consequently, individuals must assume personal responsibility for their values ​​and examine them from a multi-layered perspective.

United Nations

The United Nations High Commissioner for Human Rights serves as the coordinator for the United Nations' education and public information programs in the field of human rights. The United Nations General Assembly regards the Universal Declaration of Human Rights as central to the realization of the rights enshrined therein.

Article 26.2 of the Declaration recognizes the role of educators in achieving the social order envisioned by the Declaration—specifically through the promotion of positive social skills among diverse social and cultural groups.

Article 29 of the Convention on the Rights of the Child calls upon nation-states to ensure that children are able to develop respect for their own cultural identity, language, and values, as well as for the cultures, languages, and values ​​of others.

The United Nations' 1993 Vienna Declaration and Programme of Action reaffirmed the importance of human rights; consequently, the period from 1995 to 2004 was proclaimed the "United Nations Decade for Human Rights Education." UNESCO accepts the responsibility of promoting human rights education and served as a key organizer of the United Nations' "Decade for Human Rights Education." UNESCO endeavors to promote human rights education through various means.

 

Vocational education - Explanation of Vocational education and The Objective of Vocational education.

 

Explanation of Vocational Education

Vocational education is a form of education that prepares individuals for a skilled craft or profession. It can also be defined as the type of education provided to prepare an individual for a specific occupation. Depending on the country, vocational education is known by various names, including 'Career and Technical Education,' as well as acronyms such as TVET (Technical and Vocational Education and Training—a term used by UNESCO) and TAFE (Technical and Further Education). TVE encompasses all forms and levels of education that provide knowledge and skills related to occupations across various sectors of economic and social life; it utilizes formal, informal, and non-formal learning methods within both school-based and work-based learning contexts. To achieve its goals and objectives, TVE focuses on learning and mastering specific techniques—as well as the scientific principles underlying them—and on developing general knowledge, skills, and values.

A vocational school is a type of educational institution specifically designed to provide vocational education.

Vocational education can be provided at the post-secondary, further education, and higher education levels. At the post-secondary level, vocational education is often provided by highly specialized trade schools, technical schools, community colleges, further education colleges (in the UK), vocational universities, and institutes of technology (formerly known as polytechnic institutes).

Overview

Historically, most vocational education took place in classrooms or workplaces, where students learned trade skills and theory from accredited instructors or renowned professionals. However, in recent years, the trend of online vocational education has grown rapidly, making it easier than ever for students—even those living far from traditional vocational schools—to acquire a diverse range of trade skills and soft skills from renowned professionals.

Across the globe, new trends have emerged in the implementation of TVET (Technical and Vocational Education and Training) and skills development. Since the late 1980s, many governments have begun to emphasize the role of education in effectively preparing students for the world of work. This perspective—dubbed "New Vocationalism"—placed industry skill requirements at the center of discussions regarding the purpose of public education. TVET and skills development came to be regarded as a crucial component of fostering economic growth, and specifically, of addressing the problem of youth unemployment.

General education systems had proven ineffective in developing the skills that many adolescents and adults required to secure employment within the industry. During the late 1980s and early 1990s, new vocational curricula and courses were introduced and expanded—often developed in collaboration with the industry. Concurrently, there was also an increase in the variety of work-based learning opportunities available to young people.

The Objective of Vocational Education

TVET serves multiple objectives. One of its primary aims is to prepare young people for the workforce. This is achieved by enabling them to acquire and develop work-related skills, as well as to master the foundational knowledge and scientific principles associated with those skills. The definition of "work" is very broad; therefore, it encompasses both formal employment and self-employment. To foster self-employment, TVET curricula often incorporate training in entrepreneurship. Another related aspect involves the social reproduction of professional and vocational practices—as well as their transformation.

Another role associated with TVET is to facilitate continuous professional development. Due to the rapid pace of technological change, it has become imperative for employees to constantly update their knowledge and skills. Unlike in the past—when an individual could remain in the same job throughout their entire working life—changing professions multiple times has become a common occurrence in today's world. TVET facilitates this flexibility in two ways. The first involves providing a broad foundation of technical knowledge and "transversal skills" (general competencies), which serves as a basis for transitioning into various professions. The second involves providing continuous vocational training to the workforce. In contrast to the industrial models of the old economy, the responsibility for continuous self-renewal in today's global economy now rests primarily with the individual employee. In the past, employees enjoyed lifelong job security—characterized by full-time employment, clearly defined roles, and established career paths. This is no longer the case. Today's knowledge-based global economy is defined by rapid changes in technology and working methods. Consequently, employees often find themselves "redundant" or obsolete, and are left without employment. It is now the responsibility of TVET to reskill such individuals, enabling them to secure new employment and return to the workforce. Beyond providing work-related education, TVET also serves as a vehicle for personal development and empowerment. This encompasses the cultivation of individual capabilities that enable a person to realize their full potential—whether in the realm of salaried employment, self-employment, or in the pursuit of professional interests and life goals extending beyond work. Furthermore, TVET aims to assist individuals in overcoming limitations or barriers stemming from their birth circumstances or prior educational backgrounds.

From a developmental perspective, TVET fosters economic growth by enhancing workforce productivity. The benefits derived from increased productivity far outweigh the costs incurred for training (whether direct or indirect), thereby resulting in economic expansion. Much like any other form of education, TVET contributes to socio-economic development by enhancing individuals' capacity to adopt behaviors and practices that are socially beneficial and valuable. As with all other forms of education, TVET also seeks to cultivate the broad spectrum of individual capabilities that characterize an educated person. Thus, the objective of imparting comprehensive knowledge is to foster critical and creative thinking. TVET also aims to develop the capabilities essential for effective communication and effective interpersonal relationships.

Private sector

Private TVET providers encompass both for-profit and non-profit institutions. Several factors underpinned the measures taken to promote the expansion of private TVET, including the limited capacities of public TVET providers and their lack of accountability to enterprises and trainees. Private TVET providers were expected to be more accountable, as they were subject to fewer bureaucratic constraints compared to public institutions (particularly within centralized systems). Their presence was expected to help enhance quality across the entire system; in many developing countries, government budgets have proven to be a weak and unreliable source of TVET funding, and consequently, a primary objective was to finance TVET systems by increasing contributions from beneficiaries—including employers and trainees.

Since 2005, private TVET provision has emerged as a significant and growing segment of the TVET sector in Sub-Saharan Africa, the Middle East, and North Africa. In some countries—such as Lebanon—enrollment in private TVET institutions has surpassed that of public institutions. In Jordan, the government has actively promoted private provision at the community college level. However, not all experiences with privately owned institutions or NGOs have been positive; their curricula have often focused on professional fields that typically do not require substantial capital investment, thereby making it easier for private providers to enter and exit the sector. Quality-related issues have also surfaced in contexts where market-based information regarding quality has not been readily available.

Secondary education in the United States - Academies, Government High School and Levels of education in the United States.

                                                                                 

    

In the United States, secondary education covers the final six or seven years of compulsory formal education. It concludes with the twelfth grade (ages 17–18). It begins in either the sixth grade (ages 11–12) or the seventh grade (ages 12–13), varying by state and, at times, by school district.

Secondary education in the United States is completed in two stages. The first stage, as classified by the International Standard Classification of Education (ISCED), is the "lower secondary stage," referred to as "middle school" or "junior high school." Middle schools serve students in the sixth, seventh, and eighth grades, whereas junior high schools serve only students in the seventh and eighth grades.

The second stage is ISCED's "upper secondary stage," known as "high school" or "senior high school"; this serves students from the ninth through the twelfth grades. There is some debate regarding the precise age at which students transition to the next stage, and variations can be observed across different states; furthermore, middle schools often include grades that are almost invariably considered part of "primary school."

Academies

Today, "academy" is a common term denoting post-secondary education—particularly its most specialized or liberal arts-oriented aspects. However, during the 18th and 19th centuries, "academy" was the term used for what later came to be known as the high school. In most towns, there were no public schools above the primary level. Generally, colleges initially included a preparatory unit, which was gradually phased out by 1900.

In the nineteenth century, the term "academy" was used for what later became known as the high school; in most parts of the U.S., there were no public schools above the primary level. Some older high schools—such as Corning Free Academy—retained this term in their names (Corning Free Academy was later reclassified as a middle school and closed in 2014). In 1753, Benjamin Franklin founded the Academy and Charitable School of the Province of Pennsylvania. In 1755, its name was changed to the College, Academy, and Charitable School of Philadelphia. Today, it is known as the University of Pennsylvania. The United States Military Academy was founded in 1802 as a college; it never included a preparatory unit.

A religious revival known as the "Second Great Awakening" inspired Protestant denominations to establish academies and colleges. In 1812, in Amherst—a small town in Massachusetts—funds were raised for a secondary school: Amherst Academy; it opened in December 1814. The Academy was incorporated in 1816, and its students eventually included Emily Dickinson, Sylvester Graham, and Mary Lyon (founder of Mount Holyoke College). By 1821, it had also incorporated higher education through Amherst College. Beyond religion, the academy movement also emerged from the shared belief that education in classical subjects should be extended to the Western states.

Thousands of academies were established using local funds and tuition fees; most closed down within just a few years, only to be replaced by other academies. In 1860, 6,415 academies were in operation. When the Civil War broke out in 1861, they generally suspended their operations for a time; most academies in the South never reopened.

Like Amherst, many colleges began as academies; they later evolved into colleges by adding post-secondary departments, and eventually phased out their pre-collegiate academy components. Many colleges were indirectly influenced by the academy model, including Brown University in Rhode Island and Dartmouth College in New Hampshire. In 1753, Benjamin Franklin founded the "Academy and Charitable School of the Province of Pennsylvania." In 1755, its name was changed to the "College and Academy and Charitable School of Philadelphia." This institution later became the University of Pennsylvania.

By 1840, 3,204 academies and similar secondary schools were in operation. Most schools lasted only a few years, yet new schools continued to open in their place; by 1860, 6,415 schools were operating nationwide. The first public secondary schools emerged around the 1830s and 1840s in affluent, socio-economically homogeneous communities, and they underwent significant expansion in the post-1865 era—a trend that continued through the 1890s.

Government High School

In the 19th century, many high schools housed a "normal school," where students were trained to become teachers in common schools. Those enrolled in these programs were primarily young women who intended to teach for a few years before getting married.

When education at this level became free, and when compulsory education laws mandated school attendance for adolescents up to a certain age, there was a tremendous surge in high school enrollment. It was believed that every American student, regardless of their aptitude, should have the opportunity to partake in this educational experience.

In 1892, in response to the various educational philosophies prevalent at the time, the National Education Association established a working group of educators known as the "Committee of Ten." This committee recommended a twelve-year course of study, comprising eight years of elementary education followed by four years of high school education. Rejecting proposals suggesting that high schools should, from the outset, segregate students into separate tracks—one for college preparation versus vocational training, and in some instances, even based on caste or race—they unanimously recommended that "every subject taught in a secondary school should be taught to every student in the same way and to the same extent, as long as he pursues it; no matter what the destination of the student is to be after leaving school, or how short or how long his school life may be."

Levels of education in the United States

Middle School / Junior High School

Middle schools and junior high schools are educational institutions that serve as a link between primary and high school education. "Middle" schools typically educate students in the sixth, seventh, and eighth grades; however, in some districts, middle schools consist solely of the 7th and 8th grades. "Junior high" schools, on the other hand, typically do not include the sixth grade but often include the ninth grade. Occasionally, middle and junior high schools may also include the fifth grade.

Upon enrolling in middle school or junior high, students begin following a class schedule in which they study with multiple teachers in different classrooms throughout the day. (This marks a significant departure from the primary or elementary school model, where students remain in a single classroom with a single teacher.) These schools typically feature a core group of four or five (if the curriculum includes a foreign language) main academic subjects—English (or "Language Arts"), Science, Mathematics, History (or "Social Studies"), and in some schools, a foreign language—along with two to four additional classes, which may be elective, supplementary, or remedial academic courses.

Some students also begin taking foreign language courses or advanced mathematics and science classes as early as middle school. Schools typically offer instruction in Spanish and French; German is also frequently available, while Latin, Chinese, Japanese, and/or Greek are occasionally offered as well. In addition to pre-algebra and other preparatory courses for high school mathematics, Algebra I and Geometry—both of which are typically high school-level subjects—are often taught. Schools also offer classes in Earth Science, Life Science, or Physical Science. Physical education classes (also referred to as "PE," "phys ed," "kinesiology," or "gym") are typically mandatory for a specific period of time. For Social Studies, some schools offer classes in American History, Geography, and World History.

Many schools also offer "Honors classes" for motivated and gifted students, where the academic level is higher and significantly greater expectations are placed upon enrolled students.

Intermediate school

"Intermediate school" is a term that is rarely used. It may serve as an alternative name for "middle school" (particularly in New York City public schools), or it may refer to schools that cover the final years of primary education—specifically, the years immediately preceding middle school or junior high school—typically spanning from Grade 3 or 4 through Grade 5 or 6. These schools may also be referred to as "upper elementary" schools.

High School / Senior High School in the United States

High schools—or senior high schools—are educational institutions that provide instruction spanning from the 8th, 9th, or 10th grade through the 12th grade. Most American high schools are "comprehensive high schools," which admit all students from their local area—regardless of their academic ability or whether they have chosen a vocational or college-preparatory track. Students exercise a significant degree of control over their education and can even select their own core courses; however, the level of this autonomy varies from state to state and from school to school. These schools are administered by local school districts rather than by the federal government.

Some states and cities operate specialized high schools that require an entrance examination and admit only the highest-performing students; examples of such schools include Boston Latin School, several schools within New York City's "Specialized High Schools" system, and Thomas Jefferson High School for Science and Technology in Alexandria, Virginia. Other high schools place a special emphasis on the arts. Some schools are designed for students who struggle to succeed within a standard academic framework, while others—such as Harvey Milk High School—were established to serve specific social groups, such as LGBT students.

Most states operate specialized residential schools for students with visual or hearing impairments; however, many such students receive their education within mainstream classrooms at standard schools. Many states also run residential high schools dedicated to exceptionally gifted students in specialized fields such as science, mathematics, or the arts. A very small number of high schools are also operated by the Department of Defense within military bases, providing education to the children of military personnel.

Most high schools offer specialized classes for motivated and gifted students, known as "Honors" classes; The standard of education in these classes is high, and students enrolled in them are held to significantly higher expectations. Some high schools offer curricula such as 'Regular Honors' (H) (sometimes referred to as 'Advanced'), 'Advanced Placement' (AP), or 'International Baccalaureate' (IB); all of these represent specialized forms of 'Honors' classes. There are also international schools available that conduct study programs aligned with foreign educational systems—such as those of Britain and France. Some schools also operate 'dual-enrollment' programs, under which students can enroll in select university courses and earn academic credits toward both their university and high school studies. Upon completing their studies (graduating) from high school or senior high school, students are awarded a 'High School Diploma.' Subsequently, their secondary education is considered complete, and students may proceed to pursue higher-level (tertiary) education.

Primary education in the United States - Preschool and Elementary school in the United States.

 

The United States does not have a national or federal education system. However, while there are more than fifty independent education systems—each administered by a state or territory, the Bureau of Indian Education, or the Department of Defense Dependents Schools—they share many similarities. Education is provided through public and private schools, as well as by individuals through homeschooling. Educational standards are established at the state or territorial level by a supervisory body; this body typically takes the form of a Board of Regents, a State Department of Education, a State College Board, or a combination thereof. The majority of total funding—amounting to $1.3 trillion—comes from state and local governments, while the federal share of funding stood at approximately $250 billion in 2024, an increase from the roughly $200 billion allocated in previous years.

In the late 18th and early 19th centuries, regular attendance was not mandatory in most schools across the United States. In many regions, students attended school for no more than three to four months out of the year. Under state laws, education is now compulsory within a specific age range; this range typically begins between the ages of five and eight and concludes between the ages of sixteen and nineteen, depending on the specific state. This requirement can be fulfilled by attending public or state-certified private schools, or through an approved homeschooling program. Compulsory education is divided into three levels: elementary school, middle or junior high school, and high school. As of 2013, approximately 87% of school-aged children attended state-funded public schools, about 10% attended private schools funded through tuition and endowments, and roughly 3% received their education through homeschooling. Between 2012 and 2022, enrollment in public kindergartens, primary schools, and secondary schools declined by 4%, while enrollment in private or charter schools for the same age group increased by 2%.

Numerous public and private colleges and universities offer a wide range of options for post-secondary education. Post-secondary education is broadly categorized into undergraduate colleges (which lead to a first tertiary degree) and graduate schools. Higher education encompasses public and private research universities—typically private liberal arts colleges—community colleges, for-profit institutions, and various other types of specialized and hybrid institutions. College enrollment rates in the United States have long exhibited an upward trend. Concurrently, student debt has surged to $1.5 trillion. According to rankings compiled by various organizations, the majority of the world's finest universities are located in the United States; this includes 19 of the top 25 institutions, as well as the most renowned university—Harvard University. Total enrollment in U.S. post-secondary institutions declined from 18.1 million in 2010 to 15.4 million in 2021.

In the 2020–21 academic year, total expenditure on U.S. public primary and secondary schools amounted to $927 billion (measured in constant 2021–22 dollars). In 2010, total per-student expenditure on primary, secondary, and post-secondary education in the U.S. exceeded that of any other OECD country (a group comprising nearly all nations classified as "developed" by the International Monetary Fund and the United Nations); furthermore, the U.S. education sector's share of the country's Gross Domestic Product (GDP) was higher than that of the average OECD country. In 2014, the nation allocated 6.2% of its GDP to education across all levels—a figure that was 1.0 percentage point higher than the OECD average of 5.2%. In 2014, the Economist Intelligence Unit ranked the U.S. education system as the 14th best in the world. According to the 'Programme for International Student Assessment' (PISA), coordinated by the OECD, the overall knowledge and skills of 15-year-old American students—particularly in the fields of reading, mathematics, and science—are ranked 19th globally. In this assessment, the average American student scored 495 points, while the OECD average stood at 488 points. In 2017, 46.4% of Americans aged 25 to 64 had attained some form of post-secondary education. Among Americans aged 25 to 34, 48% had attained some form of tertiary education, which is approximately 4% higher than the OECD average of 44%. Furthermore, 35% of Americans aged 25 and older hold a bachelor's degree or a higher level of education.

Primary education in the United States

In the United States, primary education (also referred to as elementary education) generally encompasses the first seven to nine years of formal schooling in most localities. It is typically provided in elementary schools; this category also includes middle schools. Preschool programs—which are less formal in nature and generally not mandated by law—are typically not considered part of primary education. The first year of primary education is commonly known as kindergarten and begins at or around the age of 5 or 6. Subsequent years are typically designated by grade level—such as the first grade, second grade, and so on. Elementary schools generally extend through the sixth grade, which students typically complete at the age of 11 or 12. Some elementary schools transition students to middle school after the fourth or fifth grade.

In 2016, there were 88,665 elementary schools in the United States (66,758 public and 21,907 private).

Preschool

Some private and public schools offer pre-kindergarten (also known as Pre-K) facilities as part of their elementary school programs. According to the Education Commission of the States (ECS), twelve states—Alabama, Florida, Georgia, Iowa, New Jersey, New Mexico, New York, Oklahoma, West Virginia, Wisconsin, and Vermont—as well as the District of Columbia, offer some form of universal pre-kindergarten.

The first three to five years of a person's life may constitute the most critical phase of their education (referred to as the preschool years). During this period, children's brains undergo physical, intellectual, and emotional development in various ways; this includes aspects such as curiosity, character formation, personality, cognitive abilities, language proficiency, and social skills.

Since 1965, the federal government has promoted state-run programs, such as "Head Start"—a program administered under the oversight of the United States Department of Health and Human Services. By 2020, this program had assisted more than 37 million preschool-aged children and their families; in the 2019 fiscal year alone, it provided services to over one million children. In addition to providing health and nutrition services to low-income families, Head Start places a strong emphasis on the holistic development and education of children.

Elementary school in the United States

Elementary schools are institutions that provide education for grades ranging from Kindergarten (K) or Grade 1 up to Grade 4, 5, or 6. Students may attend four-year, five-year, six-year, or seven-year public or private elementary schools. Upon successfully completing their elementary education, students advance to middle school, also known as junior high school. Depending on the specific school district, some students attend separate middle schools; these schools typically cover grades 6 through 8, after which students proceed to high school—also referred to as senior high school. Additionally, students may have the option to attend elementary schools that encompass all eight primary grades. In such cases, students transition directly to high school, or senior high school.

In most elementary schools across the United States, a single class of students is assigned to a specific teacher and a designated classroom for the entire academic year. These students spend the majority of the school year together in the same classroom, learning from the same teacher; the teacher is expected to supervise their students at all times (with the exception of lunch and recess periods). Schools possessing greater financial resources may employ specialist teachers to instruct specific subjects—such as art, music, and science; in such schools, the primary teacher temporarily hands over the entire class to the specialist teacher for instruction in these subjects, subsequently resuming supervision of the class. This approach stands in stark contrast to the "course model" adopted at the middle school, high school, and college levels. Under the course model, students enroll in different courses each semester; these courses are typically taught by different teachers in different classrooms, necessitating that students move from one classroom to another throughout the school day.

Rainbow - a bright phenomenon in the sky | Rainbow visibility

 

The rainbow that appears in the sky after rain is an optical phenomenon. It is caused by the refraction, internal reflection, and scattering of light in water droplets, resulting in a continuous band of colors across the sky. A rainbow appears as a circular arc with multiple colors. A rainbow formed by sunlight always appears in the sky directly opposite the sun. Rainbows can also be formed by various forms of water in the air, including not only rain, but also mist, spray, and dew.

A rainbow can be a complete circle. However, usually, a person can only see a portion of the rainbow, appearing above the ground and centered along the line connecting the observer's eye to the sun.

In a primary rainbow, the outer edge of the arc appears red, and the inner edge appears violet. This rainbow is formed when light enters a water droplet, refracts, is internally reflected off the back of the droplet, and then refracts again upon exiting.

In a secondary rainbow, a second arc appears outside the primary arc, and its color sequence is reversed, with the inner edge being red. This occurs because the light is reflected twice inside the droplet before exiting.

Rainbow visibility

A rainbow appears when water droplets are present in the air and sunlight shines on them from a low angle behind the observer. Therefore, rainbows are usually seen in the west in the morning and in the east in the evening. The most beautiful rainbows occur when half the sky is covered with rain clouds and the observer is facing away from the sun. This creates a bright rainbow against a dark background. Often, a larger but fainter secondary rainbow also appears. It is located about 10° outside the primary rainbow and has its colors in reverse order.

This rainbow effect is also common near waterfalls or fountains. Additionally, this effect can be artificially created by spraying water droplets into the air on a sunny day. On a moonlit night, a lunar or night rainbow sometimes appears. In low light, humans see fewer colors, so lunar rainbows often appear white.

Capturing the entire rainbow in a single frame is difficult, as it requires a 84° viewing angle. For a 35mm camera, this requires a wide-angle lens with a focal length of 19mm or less. However, software that combines multiple overlapping images to create panoramas now makes it easier to capture the entire rainbow and secondary arc.

From above the Earth, such as from an airplane, a rainbow sometimes appears as a complete circle. This can resemble the glory phenomenon, but the glory is usually much smaller, only 5-20°. The sky inside the primary rainbow is brighter than the sky outside. This is because each water droplet is spherical and scatters light across a complete circular disc in the sky. The radius of this disc depends on the wavelength of light; red light scatters at a larger angle than blue light. Across most of the disk, the scattered light of all wavelengths combines to produce the white light that illuminates the sky. At the edge of the disk, the varying wavelengths of the scattered light create the colors of the rainbow.

The light from the primary rainbow is 96% polarized, with the polarization direction parallel to the tangent of the arc. The light from the secondary arc is 90% polarized.

The number of colors in a spectrum or rainbow

For the colors visible to the human eye, the most common and memorable sequence is Isaac Newton's seven-color system—red, orange, yellow, green, blue, indigo, and violet. To remember this sequence, one can use the mnemonic phrase "Richard of York Gave Battle in Vain" or the name of a fictional character (Roy G. Biv). This sequence is sometimes reversed and referred to as VIBGYOR. These days, rainbows are often described as having seven colors: red, orange, yellow, green, cyan, blue, and violet. The distinct categorization of primary colors is a characteristic of human perception, and the precise number of primary colors is somewhat arbitrary.

Newton, who believed his own eyesight was not particularly good at distinguishing colors, originally (in 1672) divided the spectrum into five primary colors: red, yellow, green, blue, and violet. He later added orange and indigo, resulting in seven primary colors, matching the number of notes in a musical scale. Newton's decision to divide the visible spectrum into seven colors was based on the beliefs of ancient Greek philosophers, who believed in a connection between colors, musical notes, the known objects in the solar system, and the days of the week. Scholars have noted that the color Newton called "blue" at that time is now called cyan, and "indigo" is now called blue.

The color pattern of a rainbow seen after rain differs from the spectrum, and its colors are less vibrant. Spectral blurring in a rainbow occurs because there is a distribution of exit angles for a given wavelength, rather than a single, fixed angle. Furthermore, a rainbow is a blurred version of a rainbow formed from a point source, since the angular size of the sun (0.5 degrees) is not negligible compared to the width of the rainbow (2 degrees). Therefore, the number of colors in a rainbow can differ from the number of colors in the spectrum, especially if the raindrops are very large or small. Thus, the number of colors in a rainbow varies. However, if the term "rainbow" is used incorrectly to refer to the spectrum, it generally means the number of primary colors in the spectrum.

Besides the red and violet bands, a rainbow also contains bands in the near-infrared and ultraviolet regions, although these bands are not visible to humans. The rainbow only includes frequencies near the visible spectrum because water and air become more transparent to these frequencies, causing the light to scatter. The UV band can sometimes be seen with a camera using black and white film.

The question of whether everyone sees seven colors in a rainbow is related to the theory of linguistic relativity. It has been suggested that there is a universal way of perceiving a rainbow. However, recent research suggests that the number of distinct colors perceived and their names depend on the language used; people who speak languages ​​with fewer color terms perceive fewer distinct colors.

The importance of vitamins in human life | Vitamin deficiency diseases and sources of vitamins

 

Vitamins are essential nutrients that all living organisms require in small amounts. Chemically, they are organic compounds. A compound is considered a vitamin when the body cannot produce it in sufficient quantities and therefore must obtain it from food.

Key Vitamins

Vitamin A

The chemical name for Vitamin A is retinol. It is also known as the anti-xerophthalmic vitamin. Vitamin A is essential for good vision. It also helps protect against infections. This vitamin supports the normal functioning of various parts of the body, such as the skin, hair, nails, glands, teeth, gums, and bones. The most serious problem caused by a deficiency of vitamin A is night blindness. Additionally, it can cause dry eyes due to reduced tear production and may lead to ulcers on the cornea. In children, a deficiency of vitamin A can slow growth, affecting their height. The skin and hair also become dry and dull. The risk of infections increases. Vitamin A is found in fresh fruits, milk, meat, eggs, fish oil, carrots, butter, and green vegetables. The liver converts the yellow or orange pigment called beta-carotene, found in plants, into vitamin A. Vitamin A is essential for the synthesis of the visual pigment rhodopsin. Symptoms of vitamin A deficiency include night blindness, cataracts, xerophthalmia (dry eyes), dry and cracked skin, and increased susceptibility to infections. A cataract occurs when the lens of the eye becomes cloudy and opaque.

Vitamin B

Vitamin B is essential for providing energy to the body. Deficiency of this vitamin can cause several diseases. Several types of vitamin B have been identified. All these types together are called the 'B-complex' vitamins. Although all these types are an integral part of the B-complex, they are also distinct from each other. B-complex vitamins can withstand heat up to 120 degrees Celsius. At higher temperatures, they are destroyed. This vitamin is water-soluble. Its main functions include maintaining healthy nerves and playing an active role in digestion. It increases appetite and provides energy to the body. It also helps in the absorption of nutrients. It is destroyed by alkaline substances even without heat, but it is not destroyed by boiling with acids. Sources of vitamin B complex include tomatoes, whole wheat flour, egg yolk, green leafy vegetables, almonds, walnuts, unpolished rice, plant seeds, betel nuts, oranges, grapes, milk, fresh legumes, fresh peas, lentils, liver, various vegetables, potatoes, nuts, yeast, corn, chickpeas, coconut, pistachios, fresh fruits, amla (Indian gooseberry), yogurt, spinach, cabbage, fish, egg white, oranges, rice bran, and other fruits and vegetables.

vitamin C

Vitamin C is also known as ascorbic acid. It was first isolated by Szent-György. It helps bind the cells of the body together. It aids in the development of various organs. It strengthens the blood vessels of the body. Due to its antihistamine properties, it can be beneficial for common colds and coughs. Its deficiency can cause problems such as bleeding gums, toothache, loose or falling teeth, and excessive bleeding from wounds or cuts. It can also cause dry skin. Appetite may decrease. Severe vitamin C deficiency can lead to scurvy. Vitamin C deficiency can also cause weight loss. It can lead to kidney stones, gallstones, and other types of stones formed by oxalate crystals in the body. It can cause burning or pain while urinating, or diarrhea due to an upset stomach. It can also cause anemia (low red blood cell count). Good sources of vitamin C include citrus fruits such as oranges.

vitamin D

Other names for Vitamin D are:

Vitamin D2 or ergocalciferol and Vitamin D3 or cholecalciferol.

It helps to strengthen and maintain healthy bones. It also helps regulate calcium levels in the body. A deficiency of this vitamin can lead to weak bones and an increased risk of fractures. In children, this condition is called rickets, and in adults, it is called osteomalacia. Additionally, thinning and weakening of the bones is called osteoporosis.

A deficiency can also cause kidney stones, heart problems, and calcium deposits in blood vessels and other organs. These deposits are made of calcium. This can also lead to high blood pressure, high cholesterol, and heart problems. Other symptoms include dizziness, weakness, and headaches. Digestive problems such as diarrhea can also occur. Good sources of Vitamin D include egg yolks, fish oil, vitamin D-fortified milk and butter, and sunlight, which allows the body to produce it.

Vitamin E

Vitamin E plays an important role in the formation of red blood cells in the blood. It is also known as tocopherol. This vitamin helps maintain the normal functioning of various organs and tissues in the body, such as muscles. It protects the body from a harmful form of oxygen called free radicals. This property is known as antioxidant activity. Vitamin E maintains cell membranes, which are essential for cell survival. Vitamin E also helps maintain the balance of fatty acids in the body. In premature babies, a deficiency of vitamin E can lead to a decrease in the number of red blood cells, which can cause anemia.

Historical Non-Cooperation Movement in India | Preparing for the Movement and Leader's Opinions

 

The Non-Cooperation Movement was the first mass movement launched by Mahatma Gandhi. It received widespread support from the general public. In urban areas, the middle class fully supported it, while in rural areas, farmers and tribal communities supported it. The working class also participated. Thus, it became the first truly mass movement. During World War I (1914-1918), the British imposed restrictions on the press and acquired the power to imprison people without trial. These harsh measures were continued based on the recommendations of a committee chaired by Sir Sydney Rowlatt. In response, Mahatma Gandhi launched a nationwide campaign against this law (the Rowlatt Act). In cities across North and West India, life virtually came to a standstill as shops and schools closed in support of the movement. Gandhi and local Congress leaders were arrested.

On April 13, 1919, people gathered at Jallianwala Bagh in Amritsar, some to protest the arrest of their leaders and others to attend a fair. Since they were outside the city limits, they were unaware that martial law had been imposed. General Dyer arrived with his troops and opened fire on the peaceful gathering. This massacre became known as the Jallianwala Bagh massacre. It was condemned throughout the country.

In protest, the police opened fire on a peaceful procession in Chauri-Chaura, Uttar Pradesh. An angry mob set fire to the police station, killing some policemen. These events led Gandhi to withdraw the movement, stating, "The Satyagrahis need further training. Therefore, we will resume the movement after this training."

The Beginning of the Non-Cooperation Movement

The Non-Cooperation Movement officially began on August 1, 1920, and the Congress formally adopted it as its official movement by passing a resolution at its session in Kolkata on September 4, 1920.  Those who wanted to end British colonialism in India were urged not to attend schools, colleges, or courts, and to refuse to pay taxes – Nitin Sinha was one of them. In short, everyone was asked to abstain from all forms of cooperation with the British government. Gandhi stated that if non-cooperation was sincerely followed, India would achieve self-rule (Swaraj) within one year. Further extending his movement, he supported the Khilafat Movement, which demanded the restoration of the Caliphate, a symbol of Pan-Islamism, which had recently been abolished by the Turkish leader Kemal Ataturk.

Preparing for the Movement

Gandhi hoped that by combining the Non-Cooperation Movement with the Khilafat Movement, the two main communities in India—Hindus and Muslims—would unite to end colonial rule. These movements certainly generated a wave of mass activism, unprecedented in colonial India. Students boycotted government schools and colleges. Lawyers refused to appear in court. Workers went on strike in many cities. According to government figures, 396 strikes involving six lakh workers in 1921 resulted in a loss of 70 lakh rupees. Discontent also spread to rural areas. Hill tribes defied forest laws. Peasants in Awadh refused to pay taxes. Peasants in Kumaon refused to carry goods for colonial officials. Sometimes, these acts of resistance were carried out even against the orders of local nationalist leaders. Peasants, workers, and others interpreted the movement according to their own understanding; they acted according to their own interests rather than merely following orders, thus giving their own meaning to 'non-cooperation' with colonial rule.

Louis Fischer, the American biographer of Mahatma Gandhi, wrote that "Non-cooperation became synonymous with an era in the life of India and Gandhi. Its approach to peace was negative, but its impact was very positive. It required protest, sacrifice, and discipline. It was a training ground for self-rule." For the first time since the Revolt of 1857, the Non-Cooperation Movement shook the foundations of British rule.

The decision to end the movement

On February 4, 1922, in the village of Chauri-Chaura in the Gorakhpur district, the police attempted to forcibly stop a procession, leading to an angry mob setting fire to the police station, resulting in the deaths of one police officer and 22 constables. This incident deeply affected Gandhiji. In his article in Young India on February 12, 1922, in which he wrote about the decision to end the Non-Cooperation Movement at the Congress meeting in Bardoli, Gandhiji stated, "To prevent the movement from turning violent, I am prepared to bear any insult, any harsh treatment, even death." Following this, Gandhiji focused his attention on constructive work.

Leaders' Opinions

Regarding the suspension of the Non-Cooperation Movement, Motilal Nehru remarked, "If a village in Kanyakumari violated the principle of non-violence, should a village in the Himalayas be punished for it?" Responding to this, Subhas Chandra Bose stated, "Ordering the withdrawal of the movement at a time when public enthusiasm was at its peak was a major disaster for the country." The suspension of the movement affected Gandhi's popularity. On March 10, 1922, Gandhi was arrested, and Judge Broomfield sentenced him to six years in prison for inciting sedition. He was released on February 5, 1924, due to poor health.
