Education is the transmission of knowledge and and the development of . Formal education happens in a complex institutional framework, like public . Non-formal education is also structured but takes place outside the formal schooling system, while informal education is unstructured learning through daily experiences. Formal and non-formal education are divided into levels that include early childhood education, primary education, secondary education, and tertiary education. Other classifications focus on the teaching method, like teacher-centered and student-centered education, and on the subject, like science education, language education, and physical education. The term "education" can also refer to the mental states and qualities of educated people and the academic field studying educational phenomena.
The precise definition of education is disputed, and there are disagreements about what the aims of education are and to what extent education is different from indoctrination by fostering critical thinking. These disagreements affect how to identify, measure, and improve forms of education. Fundamentally, education Socialization children into society by teaching cultural values and social norm. It equips them with the skills needed to become productive members of society. This way, it stimulates economic growth and raises awareness of local and global problems. Organized institutions affect many aspects of education. For example, governments set Education policy to determine when school classes happen, what is taught, and who can or must attend. International organizations, like UNESCO, have been influential in promoting primary education for all children.
Many factors influence whether education is successful. Psychology factors include motivation, intelligence, and personality. Social factors, like socioeconomic status, ethnicity, and gender, are often linked to discrimination. Further factors include access to educational technology, teacher quality, and parent involvement.
The main academic field investigating education is called education studies. It examines what education is, what aims and effects it has, and how to improve it. Education studies has many subfields, like philosophy, psychology, sociology, and economics of education. It also discusses comparative education, pedagogy, and the history of education.
In prehistory, education happened informally through oral communication and imitation. With the rise of ancient civilizations, writing was invented, and the amount of knowledge grew. This caused a shift from informal to formal education. Initially, formal education was mainly available to elites and religious groups. The invention of the printing press in the 15th century made books more widely available. This increased general literacy. Beginning in the 18th and 19th centuries, public education became more important. This development led to the worldwide process of making primary education available to all, Free education, and compulsory up to a certain age. Today, over 90% of all primary-school-age children worldwide attend primary school.
Some theorists provide precise definitions by identifying the specific features that are exclusive to all forms of education. Education theorist R. S. Peters, for instance, outlines three essential features of education, which include that knowledge and understanding are imparted to the student and that this process is beneficial and done in a morally appropriate manner. Such precise definitions often succeed at characterizing the most typical forms of education. However, they often face criticism because less common types of education occasionally fall outside their parameters. The difficulty of dealing with counterexamples not covered by precise definitions can be avoided by offering less exact definitions based on family resemblance instead. This means that all the forms of education are similar to each other, but they need not share a Essence that all of them have in common. Some education theorists, such as Keira Sewell and Stephen Newman, hold that the term "education" is context-dependent.
Axiology or of education state that it is part of the nature of education to lead to some kind of improvement. They contrast with thin conceptions, which provide a value-neutral explanation. Some theorists provide a descriptive conception of education by observing how the term is commonly used in ordinary language. Prescriptive conceptions, by contrast, define what good education is or how education should be practiced. Many thick and prescriptive conceptions see education as an activity that tries to achieve certain aims, which may range from acquiring knowledge and learning to think Rationality to nurturing character traits like kindness and honesty.
Various scholars stress the role of critical thinking to distinguish education from indoctrination. They state that mere indoctrination is only interested in instilling beliefs in the student, independent of whether the beliefs are rational; whereas education also fosters the rational ability to critically reflect on and question those beliefs. It is not universally accepted that these two phenomena can be clearly distinguished since some forms of indoctrination may be necessary in the early stages of education while the child's mind is not yet sufficiently developed. This applies to cases in which young children need to learn something without being able to understand the underlying reasons, like certain safety rules and hygiene practices.
Education can be characterized from the teacher's or the student's perspective. Teacher-centered definitions focus on the perspective and role of the teacher in the transmission of knowledge and skills in a Morality appropriate way. Student-centered definitions analyze education from the student's involvement in the learning process and hold that this process transforms and enriches their subsequent experiences. Definitions taking both perspectives into account are also possible. This can take the form of describing education as a process of a shared experience of discovering a common world and Problem solving.
Non-formal and informal education take place outside the formal schooling system. Non-formal education is a middle ground. Like formal education, it is organized, systematic, and carried out with a clear purpose, as in the case of tutoring, fitness classes, and the scouting movement. Informal education happens in an unsystematic way through daily experiences and exposure to the environment. Unlike formal and non-formal education, there is usually no designated authority figure responsible for teaching. Informal education takes place in many different settings and situations throughout one's life, usually in a spontaneous way. This is how children learn their first language from their parents and how people learn to prepare a dish by cooking together.
Some theorists distinguish the three types based on the location of learning: formal education takes place in school, non-formal education happens in places that are not regularly visited, like museums, and informal education occurs in places of everyday routines. There are also differences in the source of motivation. Formal education tends to be driven by extrinsic motivation for external rewards. In non-formal and informal education, enjoyment of the learning process usually provides intrinsic motivation. The distinction between the three types is normally clear, but some forms of education do not easily fall into one category.
In primitive cultures, most education happened on the informal level and there was mostly no distinction between activities focused on education and other activities. Instead, the whole environment acted as a form of school, and most adults acted as teachers. Informal education is often not efficient enough to teach large quantities of knowledge. To do so, a formal setting and well-trained teachers are usually required. This was one of the reasons why in the course of history, formal education became more and more important. In this process, the experience of education and the discussed topics became more abstract and removed from daily life while more emphasis was put on grasping general patterns and concepts instead of observing and imitating particular forms of behavior.
Early childhood education, also known as preschool education or nursery education, begins with birth and lasts until the start of primary school. It follows the holistic aim of fostering early child development at the physical, mental, and social levels. It plays a key role in socialization and personality development and includes various basic skills in the areas of communication, learning, and problem-solving. This way, it aims to prepare children for their entry into primary education. Preschool education is usually optional, but in some countries, such as Brazil, it is mandatory starting from the age of four.
Primary (or elementary) education usually starts within the ages of five to seven and lasts for four to seven years. It does not have any further entry requirements, and its main goal is to teach the basic skills in the fields of reading, writing, and mathematics. It also covers the core knowledge in other fields, like history, geography, the sciences, music, and art. A further aim is to foster personal development. Today, primary education is compulsory in almost all countries, and over 90% of all primary-school-age children worldwide attend primary school.
Secondary education follows primary education and usually covers the ages of 12 to 18 years. It is commonly divided into lower secondary education (middle school or junior high school) and upper secondary education (high school, senior high school, or college depending on the country). Lower secondary education normally has the completion of primary school as its entry requirement. It aims to extend and deepen the learning outcomes and is more focused on subject-specific curricula and teachers are specialized in only one or a few specific subjects. One of its aims is to familiarize students with the basic theoretical concepts in the different subjects. This helps create a solid basis for lifelong learning. In some cases, it also includes basic forms of vocational training. Lower secondary education is compulsory in many countries in Central and East Asia, Europe, and America. In some countries, it is the last stage of compulsory education. Mandatory lower secondary education is not as prevalent in Arab states, sub-Saharan Africa, and South and West Asia.
Upper secondary education starts roughly at the age of 15 and aims to provide students with the skills and knowledge needed for employment or tertiary education. Its requirement is usually the completion of lower secondary education. Its subjects are more varied and complex and students can often choose between a few subjects. Its successful completion is commonly tied to a formal qualification in the form of a high school diploma. Some types of education after secondary education do not belong to tertiary education and are categorized as post-secondary non-tertiary education. They are similar in complexity to secondary education but tend to focus more on vocational training to prepare students for the job market.
In some countries, tertiary education is used as a synonym of higher education, while in others, tertiary education is the wider term. Tertiary education expands upon the foundations of secondary education but has a more narrow and in-depth focus on a specific field or subject. Its completion leads to an academic degree. It can be divided into four levels: short-cycle tertiary, Bachelor's, Master's, and doctoral level education. These levels often form a hierarchical structure with later levels depending on the completion of previous levels. Short-cycle tertiary education focuses on practical matters. It includes advanced vocational and professional training to prepare students for the job market in specialized professions. Bachelor's level education, also referred to as undergraduate education, tends to be longer than short-cycle tertiary education. It is usually offered by universities and results in an intermediary academic certification in the form of a bachelor's degree. Master's level education is more specialized than undergraduate education. Many programs require independent research in the form of a master's thesis as a requirement for successful completion. Doctoral level education leads to an advanced research qualification, normally in the form of a doctor's degree, such as a Doctor of Philosophy (PhD). It usually requires the submission of a substantial academic work, such as a dissertation. More advanced levels include post-doctoral studies and habilitation.
Successful participation in formal education usually results in a form of certification that is required for higher levels of education and certain professions. Undetected cheating in exams, for example, by using a cheat sheet, threatens to undermine this system if unqualified students are certified.
In most countries, primary and secondary education are free of charge. There are significant global differences in the cost of tertiary education. A few countries, like Sweden, Finland, Poland, and Mexico, offer tertiary education for free or at a low cost. In some countries, like the United States and Singapore, tertiary school Tuition payments are high and students often have to take substantial loans to afford their studies. High costs of education can constitute a significant barrier to students in developing countries whose families may be unable to afford school fees, uniforms, and textbooks.
Alternative education is an umbrella term for forms of schooling that differ from the mainstream traditional approach. Differences may include learning environment, subjects, or the teacher-student relationship. Alternative schooling is characterized by voluntary participation, relatively small class and school sizes, and personalized instruction. This often results in a more welcoming and emotionally safe atmosphere. Alternative education encompasses many types like charter schools and special programs for problematic or gifted children. It also includes homeschooling and unschooling. There are many alternative schooling traditions, like Montessori schools, Waldorf schools, Round Square, Escuela Nueva, free schools, and democratic schools. Alternative education also includes indigenous education, which focuses on the transmission of knowledge and skills from an indigenous heritage and employs methods like narration and storytelling. Further types of alternative schools include Gurukula in India, Madrasa in the Middle East, and in Jewish tradition.
Some distinctions focus on who receives education. Categories by the age of the learner are childhood education, adolescent education, adult education, and elderly education. Categories by biological sex of the students include single-sex education and mixed-sex education. Special education is education that is specifically adapted to meet the unique needs of students with disabilities. It covers various forms of impairments on the intellectual, social, communicative, and physical levels. It aims to overcome the challenges posed by these impairments. This way, it provides the affected students with access to an appropriate educational structure. When understood in the broadest sense, special education also includes education for very gifted children who need adjusted curricula to reach their fullest potential.
Classifications based on the teaching method include teacher-centered education, in which the teacher takes center stage in providing students with information, and student-centered education, in which students take on a more active and responsible role in shaping classroom activities. For conscious education, learning and teaching happen with a clear purpose in mind. Unconscious education occurs on its own without being consciously planned or guided. This may happen in part through the personality of teachers and adults, which can have indirect effects on the development of the student's personality. Evidence-based education uses scientific studies to determine which methods of education work best. Its goal is to maximize the effectiveness of educational practices and policies by ensuring that they are informed by the best available empirical evidence. It includes evidence-based teaching, evidence-based learning, and school effectiveness research.
Autodidacticism, or self-education, happens without the guidance of teachers and institutions. It mainly occurs in adult education and is characterized by the freedom to choose what and when to study, which is why it can be a more fulfilling learning experience. The lack of structure and guidance can result in aimless learning, and the absence of external feedback may lead autodidacts to develop false ideas and inaccurately assess their learning progress. Autodidacticism is closely related to lifelong education, which is an ongoing learning process throughout a person's entire life.
Categories of education based on the subject include science education, language education, art education, religious education, physical education, and sex education. Special mediums, such as radio or websites, are used in distance education. Examples include e-learning (use of computers), m-learning (use of mobile devices), and online education. They often take the form of open education, in which the courses and materials are made available with a minimal amount of barriers. They contrast with regular classroom or onsite education. Some forms of online education are not open education, such as full online degree programs offered by some universities.
State education, also referred to as public education, is funded and controlled by the government and available to the general public. It normally does not require tuition fees and is thus a form of free education. Private education, by contrast, is funded and managed by private institutions. Private schools often have a more selective admission process and offer paid education by charging tuition fees. A more detailed classification focuses on the social institution responsible for education, like family, school, civil society, state, and church.
Compulsory education is education that people are legally required to receive. It concerns mainly children who need to visit school up to a certain age. It contrasts with voluntary education, which people pursue by personal choice without a legal requirement.
On an economic level, people become productive members of society through education by acquiring the technical and analytical skills needed to pursue their profession, produce goods, and provide services to others. In early societies, there was little specialization, and each child would generally learn most of the skills that the community required to function. Modern societies are increasingly complex and many professions are only mastered by relatively few people who receive specialized training in addition to general education. Some of the skills and tendencies learned to function in society may conflict with each other, and their value depends on the context of their usage. For example, cultivating the tendency to be inquisitive and question established teachings promotes critical thinking and innovation, but in some cases, obedience to an authority is required to ensure social stability.
By helping people become productive members of society, education stimulates economic growth and reduces poverty. It helps workers become more skilled and thereby increases the quality of the produced goods and services, which in turn leads to prosperity and increased competitiveness. Public education is often understood as a long-term investment to benefit society as a whole. The rate of return is especially high for investments in primary education. Besides increasing economic prosperity, it can also lead to technological and scientific advances as well as decrease unemployment while promoting social equity. Increased education is associated with lower birth rates, in part because education augments the awareness of family planning, creates new opportunities for women, and tends to raise the age of marriage.
Education can prepare a country to adapt to changes and successfully face new challenges. It can help raise awareness and contribute to the solution of contemporary global problems, such as climate change, sustainability, and the widening inequalities between the rich and the poor. By making students aware of how their lives and actions affect others, it may inspire some to work toward realizing a more sustainable and fair world. This way, education serves not just the purpose of maintaining the societal status quo, but can also be an instrument of social progress. That applies also to changing circumstances in the economic sector. For example, technological advances, particularly increased automation, are accompanied by new demands on the workforce, which education can help address. Changing circumstances may render currently taught skills and knowledge redundant while shifting the importance to other areas. Education can be used to prepare people for such changes by adjusting the curriculum, introducing subjects like digital literacy, promoting skills in handling new technologies, and including new forms of education such as massive open online courses.
On a more individual level, education promotes personal development. This can include factors such as learning new skills, developing Aptitude, fostering creativity, and increasing self-knowledge as well as improving problem-solving and decision-making abilities. Education also has positive effects on health and well-being. Key factors responsible for these effects are that educated individuals tend to be better informed about health issues and adjust their behavior accordingly, have a better social support network and coping strategies, and have a higher income, which allows them access to high-quality healthcare services. The social importance of education is recognized by the annual International Day of Education on January 24. The United Nations declared the year 1970 the International Education Year.
Various aspects of formal education are regulated by the education policy of governmental institutions. These policies determine at what age children need to attend school and at what times classes are held as well as issues pertaining to the school environment, like infrastructure. Regulations also cover the exact qualifications and requirements that teachers need to fulfill. An important aspect of education policy concerns the curriculum used for teaching at schools, colleges, and universities. A curriculum is a plan of instruction or a program of learning that guides students to achieve their educational goals. The topics are usually selected based on their importance and depend on the type of school. The goals of public school curricula are usually to offer a comprehensive and well-rounded education, while vocational training focuses more on specific practical skills within a field. The curricula also cover various aspects besides the topic to be discussed, such as the teaching method, the objectives to be reached, and the standards for assessing progress. By determining the curricula, governmental institutions have a strong impact on what knowledge and skills are transmitted to the students. Examples of governmental institutions include the Ministry of Education in India, the Department of Basic Education in South Africa, and the Secretariat of Public Education in Mexico.
International organizations also play a key role in education. For instance, UNESCO is an intergovernmental organization that promotes education in many ways. One of its activities is to advocate education policies, like the treaty Convention on the Rights of the Child, which states that education is a human right of all children and young people. The Education for All initiative aimed to offer basic education to all children, adolescents, and adults by the year 2015 and was later replaced by the initiative Sustainable Development Goals as goal 4. Related policies include the Convention against Discrimination in Education and the Futures of Education initiative.
Some influential organizations are not intergovernmental, but non-governmental. For example, the International Association of Universities promotes collaboration and the exchange of knowledge between colleges and universities around the world, while the International Baccalaureate offers international diploma programs. Institutions like the Erasmus Programme facilitate student exchanges between countries, while initiatives such as the Fulbright Program provide a similar service for teachers.
Intelligence influences how people respond to education. It is a mental quality linked to the ability to learn from experience, to understand, and to employ knowledge and skills to solve problems. Those who have higher scores in intelligence metrics tend to perform better at school and go on to higher levels of education. Intelligence is often primarily associated with the so-called IQ, a standardized numerical metric for assessing intelligence by focusing on mathematical-logical and verbal skills. However, it has been argued that there are more types of intelligence. According to the psychologist Howard Gardner, there are distinct forms of intelligence belonging to fields like mathematics, logic, spatial cognition, language, and music. Further types affect how a person interacts with other people and with themselves. These types of intelligence are largely independent of each other, meaning that someone may excel at one type while scoring low on another.
According to proponents of learning style theory, the preferred method of acquiring knowledge and skills is another factor. They hold that students with an auditory learning style find it easy to comprehend spoken lectures and discussions, whereas visual learners benefit from information presented visually, such as in diagrams and videos. To facilitate efficient learning, it may be advantageous to incorporate a wide variety of learning modalities. Learning styles have been criticized for ambiguous empirical evidence of student benefits and unreliability of student learning style assessment by teachers. The learner's personality may also influence educational achievement. For instance, characteristics such as conscientiousness and openness to experience, identified in the Big Five personality traits, are associated with academic success. Other mental factors include self-efficacy, self-esteem, and metacognitive abilities.
Socioeconomic status depends on income but includes other factors, such as financial security, social status, social class, and quality of life attributes. Low socioeconomic status affects educational success in various ways. It is linked to slower cognitive developments in language and memory and higher dropout rates. Poor families may not have enough money to meet basic the nutritional needs of their children, causing poor development. They may also lack the means to invest in educational resources like stimulating toys, books, and computers. Additionally, they may be unable to afford tuition at prestigious schools and are more likely to attend schools in poorer areas. Such schools tend to offer lower standards of teaching because of teacher shortages or because they lack educational materials and facilities, like libraries. Poor parents may also be unable to afford private lessons if their children fall behind. In some cases, students from an economically disadvantaged background are forced to dropout from school to provide income to their families. They also have less access to information on higher education and may face additional difficulties in securing and repaying student loans. Low socioeconomic status also has many indirect negative effects by being linked to lower physical and mental health. Due to these factors, social inequalities on the level of the parents are often reproduced in the children.
Ethnic background is linked to cultural differences and language barriers, which make it more difficult for students to adapt to the school environment and follow classes. Additional factors are explicit and implicit biases and discrimination toward ethnic minorities. This may affect the students' self-esteem and motivation as well as their access to educational opportunities. For example, teachers may hold stereotypical views even if they are not overtly racist, which can lead them to grade comparable performances differently based on the child's ethnicity.
Historically, gender has been a central factor in education since the roles of men and women were defined differently in many societies. Education tended to strongly favor men, who were expected to provide for the family. Women, by contrast, were expected to manage the household and rear children, which barred most educational opportunities available to them. While these inequalities have improved in most modern societies, there are still gender differences in education. Among other things, this concerns and linked to the role of gender in education. They affect subjects like science, technology, engineering, and mathematics, which are often presented as male fields. This discourages female students from following them. In various cases, discrimination based on gender and social factors happens openly as part of official educational policy, such as the severe restrictions on female education instituted by the Taliban in Afghanistan and the school segregation of migrants and locals in urban China under the hukou system.
One aspect of many social factors is given by the expectations associated with stereotypes. They work both on an external level, based on how other people react to a person belonging to a certain group, and on an internal level, based on how the person internalizes them and acts accordingly. In this sense, the expectations may turn into self-fulfilling prophecies by causing the educational outcomes they anticipate. This can happen both for positive and negative stereotypes.
Educational technology can benefit learning in various ways. In the form of media, it often takes the role of the primary supplier of information in the classroom. This means that the teacher can focus their time and energy on other tasks, like planning the lesson and guiding students as well as assessing educational performance. Educational technology can also make information easier to understand by presenting it using graphics, audio, and video rather than through mere text. In this regard, interactive elements may be used to make the learning experience more engaging in the form of . Technology can be employed to make educational materials accessible to many people, like when using online resources. It additionally facilitates collaboration between students and communication with teachers. The use of artificial intelligence in education holds various potentials, such as providing new learning experiences to students and assisting teachers in their work, but also poses new risks associated with data privacy, false information, and manipulation. Various organizations promote student access to educational technologies, such as the One Laptop per Child initiative, the African Library Project, and Pratham.
School infrastructure also influences educational success. It includes physical aspects of the school, like its location and size as well as the available school facilities and equipment. A healthy and safe environment, well-maintained classrooms, and suitable classroom furniture as well as the availability of a School library and a School meal tend to contribute to educational success. The quality of the teacher also has an important impact on student achievement. Skilled teachers know how to motivate and inspire students and are able to adjust their instructions to the students' abilities and needs. Important in this regard are the teacher's own education and training as well as their past teaching experience. A meta-analysis by Engin Karadağ et al. concludes that, compared to other influences, factors related to the school and the teacher have the biggest impact on educational success.
Parent involvement also boosts achievement and can make children more motivated and invested if they are aware that their parents care about their educational efforts. This tends to lead to increased self-esteem, better attendance rates, and more constructive behavior at school. Parent involvement also includes communication with teachers and other school staff to make other parties aware of current issues and how they may be resolved. Further relevant factors sometimes discussed in the academic literature include historical, political, demographic, religious, and legal aspects.
Various Methodology are used to study educational phenomena. They roughly divide into quantitative, qualitative, and Multimethodology. Quantitative research emulates the methods found in the by using precise numerical measurements to gather data from many and employs statistical tools to analyze it. It aims to arrive at an objective and impersonal understanding. Qualitative research usually has a much smaller sample size and tries to get an in-depth insight into more subjective and personal factors, like how different actors experience the process of education. Mixed-methods research aims to combine data gathered from both approaches to arrive at a balanced and comprehensive understanding. Data can be collected in various ways, like using direct observation or as well as interviews and . Some research projects study basic factors affecting all forms of education, while others concentrate on one specific application, look for solutions to concrete problems, or examine the effectiveness of educational projects and policies.
The term "pedagogy" is sometimes used as a synonym for education studies, but when understood in a more restricted sense, it refers to the subfield interested in teaching methods. It studies how the aims of education, like the transmission of knowledge or fostering and , can be realized. It is interested in the methods and practices used for teaching in regular schools. Some definitions restrict it to this domain, but in a wider sense, it covers all types of education, including forms of teaching outside schools. In this general sense, it explores how teachers can bring about experiences in learners to advance their understanding of the studied topic and how the learning itself takes place.
The psychology of education studies how education happens on the mental level, specifically how new knowledge and skills are acquired as well as how personal growth takes place. It examines what factors influence educational success, how they may differ between individuals, and to what extent nature or nurture is responsible. Influential psychological theories of education are behaviorism, cognitivism, and constructivism. Closely related fields are the neurology of education and educational neuroscience, which are interested in the neuropsychological processes and changes brought about through learning.
The sociology of education is concerned with how education leads to socialization. It examines how social factors and ideology affect what kind of education is available to a person and how successful they are. Closely related questions include how education affects different groups in society and how educational experiences can form someone's personal identity. The sociology of education is specifically interested in the causes of inequalities, and its insights are relevant to education policy by trying to identify and mitigate factors that cause inequality. Two influential schools of thought are consensus theory and conflict theory. Consensus theorists hold that education benefits society as a whole by preparing people for their roles. Conflict theories have a more negative outlook on the resulting inequalities and see education as a force used by the ruling class to promote their own agenda.
The economics of education is the field of inquiry studying how education is produced, distributed, and consumed. It tries to determine how resources should be used to improve education, for example, by examining to what extent the quality of teachers is increased by raising their salary. Other questions are how smaller affect educational success and how to invest in new educational technologies. This way, the economics of education helps policy-makers decide how to distribute the limited resources most efficiently to benefit society as a whole. It also tries to understand what long-term role education plays for the economy of a country by providing a highly skilled labor force and increasing its competitiveness. A closely related issue concerns the economic advantages and disadvantages of different systems of education.
Comparative education is the discipline that examines and contrasts systems of education. Comparisons can happen from a general perspective or focus on specific factors, like social, political, or economic aspects. Comparative education is often applied to different countries to assess the similarities and differences of their educational institutions and practices as well as to evaluate the consequences of the distinct approaches. It can be used to learn from other countries which education policies work and how one's own system of education may be improved. This practice is known as policy borrowing and comes with many difficulties since the success of policies can depend to a large degree on the social and cultural context of students and teachers. A closely related and controversial topic concerns the question of whether the educational systems of developed countries are superior and should be exported to less developed countries. Other key topics are the internationalization of education and the role of education in transitioning from an authoritarian regime to a democracy.
The history of education examines the evolution of educational practices, systems, and institutions. It discusses various key processes, their possible causes and effects, and their relations to each other.
Some education theorists focus a single overarching purpose of education and see the more specific aims as means to this end. On a personal level, this purpose is often identified with helping the student lead a good life. On a societal level, education makes people productive members of society. It is controversial whether the primary aim of education is to benefit the educated person or society as a whole.
Educational ideologies are systems of basic philosophical assumptions and principles that can be used to interpret, understand, and evaluate existing educational practicies and policies. They cover various additional issues besides the aims of education, like what topics are learned and how the learning activity is structured. Other themes include the role of the teacher, how educational progress should be assessed, and how institutional frameworks and policies should be structured. There are many ideologies, and they often overlap in various ways. Teacher-centered ideologies place the main emphasis on the teacher's role in transmitting knowledge to students, while student-centered ideologies give a more active role to the students in the process. Process-based ideologies focus on what the processes of teaching and learning should be like and contrast with product-based ideologies, which discuss education from the perspective of the result to be achieved. Conservatism ideologies rely on traditional and well-established practices while Progressive ideologies emphasize innovation and creativity. Further categories are humanism, romanticism, essentialism, encyclopaedism, and pragmatism as well as Authoritarianism and democratic ideologies.
Various theories suggest that learning is more efficient when it is based on personal experience. An additional factor is to aim at a deeper understanding by connecting new to pre-existing knowledge rather than merely memorizing a list of unrelated facts. An influential developmental theory of learning is proposed by psychologist Jean Piaget, who outlines four stages of learning through which children pass on their way to adulthood: the sensorimotor, the pre-operational, the concrete operational, and the formal operational stage. They correspond to different levels of abstraction with early stages focusing more on simple sensory and motor activities, while later stages include more complex internal representations and information processing in the form of logical reasoning.
Teaching method also encompasses the use of instructional media used, such as books, , and audio-visual recordings, and having some form of test or assessment to evaluate the learning progress. Educational assessment is the process of documenting the student's knowledge and skills, which can happen formally or informally and may take place before, during, or after the learning activity. An important pedagogical aspect in many forms of modern education is that each lesson is part of a larger educational enterprise governed by a syllabus, which often covers several months or years. According to Herbartianism, teaching is divided into phases. The initial phase consists of preparing the student's mind for new information. Next, new ideas are first presented to the learner and then associated with ideas with which the learner is already familiar. In later phases, the understanding shifts to a more general level behind the specific instances, and the ideas are then put into concrete practice.
Another key aspect of ancient education was the establishment of formal education. This became necessary since the amount of knowledge grew as civilizations evolved, and informal education proved insufficient to transmit all requisite knowledge between generations. Teachers would act as specialists to impart knowledge, and education became more abstract and further removed from daily life. Formal education was still quite rare in ancient societies and was restricted to the intellectual elites. It covered fields like reading and writing, record keeping, leadership, civic and political life, religion, and technical skills associated with specific professions. Formal education introduced a new way of teaching that gave more emphasis to discipline and drills than the earlier informal modes of education. Two often-discussed achievements of ancient education are the establishment of Plato's Academy in Ancient Greece, which is sometimes considered the first institute of higher learning, and the creation of the Great Library of Alexandria in Ancient Egypt as one of the most prestigious libraries of the ancient world.
Additionally, this period saw the establishment of various institutes of higher education and research. The first universities in Europe were the University of Bologna, the University of Paris, and Oxford University. Other influential centers of higher learning were the Al-Qarawiyyin University in Morocco, the Al-Azhar University in Egypt, and the House of Wisdom in Iraq. Another key development was the creation of , which were associations of skilled Master craftsman and merchants who controlled the practice of their trades. They were responsible for vocational education, and new members had to pass through different stages on their way to masterhood.
These changes prepared the rise of public education in the 18th and 19th centuries. This period saw the establishment of publicly funded schools with the aim of providing education for all. This contrasts with earlier periods when formal education was primarily provided by private schools, religious institutions, and individual tutors. Aztecs civilization was an exception in this regard since formal education was mandatory for the youth regardless of social class as early as the 14th century. Closely related changes were to make education compulsory and free of charge for all children up to a certain age.
The establishment of public education was accompanied by the introduction of standardized curricula for public schools as well as standardized tests to assess the student's progress. Contemporary examples include the Test of English as a Foreign Language, which is a globally used test to assess English language proficiency of non-native English speakers, and the Programme for International Student Assessment, which evaluates education systems worldwide based on how 15-year-old students perform in the fields of reading, mathematics, and science. Similar changes also affected teachers by setting in place institutions and norms to guide and oversee teacher training, like certification requirements for teaching at public schools.
Emerging educational technologies have shaped contemporary education. The widespread availability of computers and the internet dramatically increased access to educational resources and made new types of education possible, such as online education. This was of particular relevance during the COVID-19 pandemic when schools globally closed for extended periods and many offered remote learning through video conferencing or pre-recorded to continue instruction. Contemporary education is also shaped by the increased globalization and internationalization of education.
