Education is the transmission of knowledge, skills, and character traits. There are many types of education. Formal education happens in a complex institutional framework, like public schools. Non-formal education is also structured but takes place outside the formal schooling system. Informal education is unstructured learning through daily experiences. Formal and non-formal education are divided into levels. They 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. Forms of education can also be distinguished by 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 socializes children into society by teaching cultural values and norms. 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 policies 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. Psychological 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 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 of education, psychology of education, sociology of education, economics of education, and comparative education. It also discusses 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. It led to the worldwide process of making primary education available to all, free of charge, and compulsory up to a certain age.
The definition of education has been explored by theorists from various fields. Many agree that education is a purposeful activity aimed at achieving goals like the transmission of knowledge, skills, and character traits. However, there is extensive debate regarding its exact nature beyond these general features. One approach is to view education as a process that occurs during educational events such as schooling, teaching, and learning. Another outlook understands education not as a process but as the product resulting from this process. It emphasizes the mental states and dispositions of educated persons. Additionally, the term may also refer to the academic field that studies the methods, processes, and social institutions involved in teaching and learning. Having a clear idea of what the term means is important to correctly identify educational phenomena. It also matters when trying to measure or improve them. The term "education" is derived from the Latin words educare, meaning "to bring up" and educere, meaning "to bring forth".
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:
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. This problem can be avoided by offering less precise definitions instead based on family resemblance. This means that all the forms of education are similar to each other but they need not share a set of essential features that all of them have in common. According to one view, the term "education" is context-dependent. This implies that its meaning varies depending on the situation in which it is used.
There is disagreement in the academic literature on whether education is an evaluative concept. Thick definitions[a] see education as an evaluative concept. They state it is part of the nature of education to be beneficial to the student or lead to some kind of improvement. Different thick definitions disagree about what kind of improvement is involved. They contrast with thin definitions, which provide a value-neutral explanation of education. A closely related distinction is between descriptive and prescriptive conceptions of education. Descriptive conceptions discuss how the term is actually used by regular speakers. Prescriptive conceptions express what good education is or how education should be practiced. Many thick and prescriptive conceptions hold that education is an activity that tries to achieve certain aims. Some concentrate on epistemic aims, like knowledge and understanding. Others give more emphasis to the development of skills, like rationality and critical thinking, and character traits, like kindness and honesty.
One approach is to focus on a single overarching purpose of education and see the more specific aims as means to this end. According to one suggestion, socialization is the aim of education. It is realized by transmitting accumulated knowledge from one generation to the next. This process helps the student to function in society as a regular citizen. More person-centered definitions focus on the well-being of the student instead. For them, education is a process that helps them lead a good life or the life they wish to lead. 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 they are rational. Education, by contrast, also fosters the rational ability to critically reflect on and question those beliefs, according to this position. However, it is not universally accepted that these two phenomena can be clearly distinguished. One reason for this view is that 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. They tend to see education as the transmission of knowledge and skills in a morally appropriate way. Student-centered definitions analyze education from the student's involvement in the learning process. They may define it as a process that transforms and enriches their subsequent experience. Definitions taking both perspectives into account are also possible. This can take the form of describing the process as the shared experience of a common world. In the shared experience, different aspects of the world are discovered and problems are posed and solved.
There are many classifications of education. One of them depends on the institutional framework and distinguishes between formal, non-formal, and informal education. Another classification includes different levels of education based on factors like the student's age and the complexity of the content. Further categories focus on the topic, the teaching method, the medium used, and the funding.
The most common division is between formal, non-formal, and informal education.[b] Formal education happens in a complex institutional framework. Such frameworks have a chronological and hierarchical order: the modern schooling system has classes based on the student's age and progress, extending from primary school to university. Formal education is usually controlled and guided by the government. It tends to be compulsory up to a certain age.
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. Examples are 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. Examples include the way children learn their first language from their parents or learning how 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 occasionally visited. 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. Non-formal and informal education are closely linked to intrinsic motivation because the learning itself is enjoyed. The distinction between the three types is normally clear for the typical cases. However, some forms of education do not easily fall into one category.
Formal education plays a central role in modern civilization, though in primitive cultures, most of the education happened on the informal level. This usually meant that there was 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. However, 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. More emphasis was put on grasping general patterns and concepts instead of observing and imitating particular forms of behavior.
Types of education are often divided into levels or stages. The most influential framework is the International Standard Classification of Education, maintained by the United Nations Educational, Scientific and Cultural Organization (UNESCO). It covers both formal and non-formal education and distinguishes levels based on the student's age, the duration of learning, and the complexity of the discussed content. Further criteria include entry requirements, teacher qualifications, and the intended outcome of successful completion. The levels are grouped into early childhood education (level 0), primary education (level 1), secondary education (levels 2–3), post-secondary non-tertiary education (level 4), and tertiary education (levels 5–8).
Early childhood education is also known as preschool education or nursery education. It is the stage of education that 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 prepares children for their entry into primary education.
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. 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 is the stage of education following primary education. It 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. It 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. In many countries, it is the last stage of compulsory education.
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. The 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. There are some types of education after secondary education that do not belong to tertiary education. They are categorized as post-secondary non-tertiary education and are similar in complexity to secondary education. However, they 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. It 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. They 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 is also referred to as undergraduate education. It 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.
Many other types of education are discussed in the academic literature, like the distinction between traditional and alternative education. Traditional education concerns long-established and mainstream schooling practices. It uses teacher-centered education and takes place in a well-regulated school environment. Regulations cover many aspects of education, such as the curriculum and the timeframe when classes start and end.
Alternative education is an umbrella term for forms of schooling that differ from the mainstream traditional approach. They may use a different learning environment, teach different subjects, or promote a different 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 schools, Escuela Nueva schools, free schools, and democratic schools. Alternative education also includes indigenous education. It focuses on the transmission of knowledge and skills from an indigenous heritage. Its methods give more emphasis to narration and storytelling.
Other distinctions between types of education are based on who receives education. Categories by the age of the learner are childhood education, adolescent education, adult education, and elderly 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.
Some classifications focus on the teaching method. In teacher-centered education, the teacher takes center stage in providing students with information. It contrasts with 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.
Autodidacticism or self-education is self-directed learning. It happens without the guidance of teachers and institutions. It mainly occurs in adult education. It is characterized by the freedom to choose what and when to study. For this reason, it can be a more fulfilling learning experience. However, the lack of structure and guidance can result in aimless learning. Due to the absence of external feedback, autodidacts may 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.
Forms of education can also be categorized by the subject and the medium used. Types based on the subject include science education, language education, art education, religious education, and physical 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.
A further distinction is based on the type of funding. Public education is also referred to as state education. It is education funded and controlled by the government. It is available to the general public. It normally does not require tuition fees and is thus a form of free education. It contrasts with private education, which is funded and managed by private institutions. Private schools often have a more selective admission process. Many 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.
Evidence-based education uses well-designed scientific studies to determine which methods of education work best. Its goal is to maximize the effectiveness of educational practices and policies. This is achieved by ensuring that they are informed by the best available empirical evidence. It includes evidence-based teaching, evidence-based learning, and school effectiveness research.
Education plays various roles in society, including in social, economic, and personal fields. On a social level, education makes it possible to establish and sustain a stable society. It helps people acquire the basic skills needed to interact with their environment and fulfill their needs and desires. In modern society, this involves a wide range of skills like being able to speak, read, and write as well as to solve problems and to perform basic arithmetic tasks. It also includes the ability to handle information and communications technology. Children are socialized into society by acquiring these skills. Another key part of socialization is to learn how to live in social groups and interact with others by coming to understand social and cultural norms and expectations. This requires an understanding of what kinds of behavior are considered appropriate in different contexts. This way, new members are introduced to the culture, norms, and values that are dominant in their society. Socialization happens throughout life but is of special relevance to early childhood education. It enables a form of social cohesion, stability, and peace needed for people to productively engage in their daily business. Education plays a key role in democracies by increasing civic participation in the form of voting and organizing and through its tendency to promote equal opportunity for all.
A further issue is to enable people to become productive members of society by learning how to contribute to it. Through education, individuals acquire 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, fostering a questioning mind is necessary to develop the ability of critical thinking 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.
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. Examples are climate change and sustainability as well as 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 reproducing society as it is but can also be an instrument of development by realizing social transformation to improve society. This applies also to changing circumstances in the economic sector, where technological advances and increased automation may cause many jobs to be lost in the coming decades. This 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. This way, subjects involving digital literacy and skills in handling new technologies can be promoted. Another example is online education in the form of massive open online courses.
On a more individual level, education promotes personal development. This can include factors such as learning new skills, developing talents, 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. While education is of high relevance in childhood, it does not end with adulthood and continues throughout life. This form of lifelong learning is of specific significance in contemporary society due to the rapid changes on many levels and the need for people to adjust to them.
Organized institutions play a key role in various aspects of education. Institutions like schools, universities, teacher training institutions, and ministries of education make up the education sector. They interact both with each other and with other stakeholders, such as parents, local communities, and religious groups. Further stakeholders are NGOs, professionals in healthcare, law enforcement, media platforms, and political leaders. Many people are directly involved in the education sector. They include students, teachers, and school principals as well as school nurses and curriculum developers.
Various aspects of formal education are regulated by the policies of governmental institutions. They 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 requirements for teachers and how they are trained. An important aspect of education policy concerns the curriculum used for teaching at schools, colleges, and universities. A curriculum is a planned sequence of instructions or a program of learning that intends to guide the experience of learners to achieve the aims of education. 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.
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 UNCRC, which states that education is a human right of all children and young people. Another was the Education for All initiative. It aimed to offer basic education to all children, adolescents, and adults by the year 2015. It 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 the exchange of colleges and universities around the world while the International Baccalaureate offers international diploma programs. Various institutions, like the Erasmus Programme, facilitate student exchanges between countries.
Several factors influence educational achievement. They include psychological factors, which concern the student as an individual, and sociological factors, which pertain to the student's social environment. Further factors are access to educational technology, teacher quality, and parent involvement. Many of these factors overlap and influence each other.
On a psychological level, relevant factors include motivation, intelligence, and personality. Motivation is the internal force propelling people to engage in learning. Motivated students are more likely to interact with the content to be learned by participating in classroom activities like discussions. This often results in a deeper understanding of the subject. Motivation can also help students overcome difficulties and setbacks. An important distinction is between intrinsic and extrinsic motivation. Intrinsically motivated students are driven by an interest in the subject and the learning experience itself. Extrinsically motivated students seek external rewards. They may strive for good grades and recognition from their peers. Intrinsic motivation tends to be more beneficial by leading to increased creativity and engagement as well as long-term commitment. Educational psychologists try to discover how to increase motivation. This can be achieved by encouraging some competition among students while ensuring a balance of positive and negative feedback in the form of praise and criticism.
Intelligence is another important factor in 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. However, it has been argued that there different types of intelligences pertaining to distinct areas. According to psychologist Howard Gardner, they can be distinguished into areas like mathematics, logic, spatial cognition, language, and music. Further types affect how a person interacts with other people and with themselves. These forms are largely independent of each other, meaning that someone may excel at one type while scoring low on another.
A closely related factor concerns learning styles. A learning style is a preferred form of acquiring knowledge and skills. According to proponents of learning style theory, students with an auditory learning style find it easy to follow spoken lectures and discussions while visual learners benefit if information is presented visually in diagrams and videos. For efficient learning, it may be beneficial to include a wide variety of learning modalities. The learner's personality may also affect educational achievement. For example, the features of conscientiousness and openness to experience from the Big Five personality traits are linked to academic success. Further mental factors include self-efficacy, self-esteem, and metacognitive abilities.
Sociological factors focus not on psychological attributes of learners but on their environment and position in society. They include socioeconomic status, ethnicity, and cultural background as well as gender. They are of interest to researchers since they are associated with inequality and discrimination. For this reason, they play a key role in policy-making in attempts to mitigate their effects.
Socioeconomic status depends on income but includes other factors as well, such as financial security, social status, and social class as well as 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 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. Students from an economically disadvantaged background often 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 males and females were defined differently in many societies. Education tended to strongly favor males, who were expected to provide for the family. Females, by contrast, were expected to manage the household and rear children, which severely hampered the educational opportunities available to them. And while these inequalities have improved in most modern societies, there are still gender differences in education. Among other things, this concerns biases and stereotypes 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.
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.
Technology plays another significant role in educational success. Educational technology is commonly associated with the use of modern digital devices, like computers. But understood in the broadest sense, it involves a wide range of resources and tools for learning, including basic aids that do not involve the use of machines, like regular books and worksheets.
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 and videos rather than through mere text. In this regard, interactive elements may be used to make the learning experience more engaging in the form of educational games. 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. Lack of educational technology affects developing countries in particular. Many efforts are made to address it, such as the One Laptop per Child initiative.
A closely related issue concerns the effects of school infrastructure. 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 library and a canteen 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.
An additional factor to boost student achievement is parent involvement. It 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.
The main discipline investigating education is called education studies, also referred to as education sciences. It tries to determine how people transmit and acquire knowledge by studying the methods and forms of education. It is interested in its aims, effects, and value as well as the cultural, societal, governmental, and historical contexts that shape education. Education theorists integrate insights from many other fields of inquiry, including philosophy, psychology, sociology, economics, history, politics, and international relations. Because of these influences, some theorists claim that education studies is not an independent academic discipline like physics or history since its method and subject are not as clearly defined. Education studies differs from regular training programs, such as teacher training, since its focus on academic analysis and critical reflection goes beyond the skills needed to be a good teacher. It is not restricted to the topic of formal education but examines all forms and aspects of education.
Various research methods are used to study educational phenomena. They can roughly be divided into quantitative, qualitative, and mixed-methods approaches. Quantitative research emulates the methods found in the natural sciences by using precise numerical measurements to gather data from many observations 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 test scores as well as interviews and questionnaires. Some research projects study basic factors affecting all forms of education while others concentrate on one specific application. Some investigations look for solutions to concrete problems while others examine the effectiveness of educational projects and policies.
Education studies encompasses various subfields like philosophy of education, pedagogy, psychology of education, sociology of education, economics of education, comparative education, and history of education. The philosophy of education is the branch of applied philosophy that examines many of the basic assumptions underlying the theory and practice of education. It studies education both as a process and as a discipline while trying to provide exact definitions of its nature and how it differs from other phenomena. It further examines the purpose of education, its different types, and how to conceptualize teachers, students, and their relation. It includes educational ethics, which investigates the moral implications of education, for example, what ethical principles underlie it and how teachers should apply them to specific cases. The philosophy of education has a long history and was already discussed in ancient Greek philosophy.
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 skills and character traits, can be realized. It is interested in the methods and practices used for teaching in regular schools and 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 the factors responsible for successful education and how these factors may differ from person to person. Important factors include intelligence, motivation, and personality. A central topic in this field is the interplay between nature and nurture and how it affects educational success. 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 social factors influence education and how it leads to socialization. Often-discussed factors are socioeconomic status, ethnicity, and gender. The sociology of education studies how these factors, together with the dominant ideology in society, 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 aspects that result in inequalities. Its insights are relevant to education policy for 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. An example is the question to what extent the quality of teachers is increased by raising their salary. Other questions are how smaller class sizes 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. It 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.
A central topic in education studies concerns questions like why people should be educated and what goals should guide this process. Many aims of education have been suggested. On a basic level, education is about the acquisition of knowledge and skills but may also include personal development and fostering of character traits. Common suggestions encompass features like curiosity, creativity, rationality, and critical thinking as well as the tendency to think, feel, and act morally. Some scholars focus on liberal values linked to freedom, autonomy, and open-mindedness. But others prioritize qualities like obedience to authority, ideological purity, piety, and religious faith. An important discussion in this regard is about the role of critical thinking and the extent to which indoctrination forms part of education. On a social level, it is often stressed that education should socialize people. This way, it turns them into productive members of society while promoting good citizenship and preserving cultural values. A controversial issue concerns who primarily benefits from education: the educated person, society as a whole, or dominant groups within society.
Educational ideologies are systems of basic philosophical assumptions and principles. 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 and how educational progress should be assessed. They also include claims on how to structure the institutional framework and policies. 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. They contrast with product-based ideologies, which discuss education from the perspective of the result to be achieved. Another classification contrasts progressivism with more traditional and conservative ideologies. Further categories are humanism, romanticism, essentialism, encyclopaedism, and pragmatism. There are also distinct types for authoritarian and democratic ideologies.
Learning theories try to explain how learning happens. Influential theories are behaviorism, cognitivism, and constructivism. Behaviorism understands learning as a change in behavior in response to environmental stimuli. This happens by presenting the learner with a stimulus, associating this stimulus with the desired response, and solidifying this stimulus-response pair. Cognitivism sees learning as a change in cognitive structures and focuses on the mental processes involved in storing, retrieving, and processing information. According to constructivism, learning is based on the personal experience of each individual. It puts more emphasis on social interactions and how they are interpreted by the learner. These theories have important implications for how to teach. For example, behaviorists tend to focus on drills while cognitivists may advocate the use of mnemonics and constructivists tend to employ collaborative learning strategies.
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. He outlines four stages of learning through which children pass on their way to adulthood. They are the sensorimotor, the pre-operational, the concrete operational, and the formal operational stage. They correspond to different levels of abstraction. Early stages focus more on simple sensory and motor activities. Later stages include more complex internal representations and information processing in the form of logical reasoning.
The teaching method concerns the way the content is presented by the teacher, for example, whether group work is used instead of a focus on individual learning. There are many teaching methods available. Which one is most efficient in a case depends on various factors, like the subject matter as well as the learner's age and competence level. This is reflected in the fact that modern school systems organize students by age, competence, specialization, and native language into different classes to ensure a productive learning process. Different subjects frequently use very different approaches. Language education often focuses on verbal learning while mathematical education is about abstract and symbolic thinking together with deductive reasoning. One central requirement for teaching methodologies is to ensure that the learner remains motivated because of interest and curiosity or through external rewards.
Further aspects of teaching methods include the instructional media used, such as books, worksheets, and audio-visual recordings, and having some form of test or assessment to evaluate the learning progress. 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. It 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.
The history of education studies the processes, methods, and institutions involved in teaching and learning. It tries to explain how they have interacted with each other and shaped educational practice until the present day. Education began in prehistory, as adults trained the young in the knowledge and skills deemed necessary in their society. For the most part, there were no specialized teachers and most adults taught the youth, usually informally during everyday activities. Education was achieved through oral communication and imitation. It could take the form of storytelling and singing to pass knowledge, values, and skills from one generation to the next.
The earliest ancient civilizations developed in the period from 3000 to 1500 BCE in Egypt, Mesopotamia, and North China. Ancient education was characterized by the invention of writing and the development of formal education. The invention of writing had a significant influence on the history of education as a whole. Through writing, it was possible to store and preserve information and make it accessible to more people. This enabled various subsequent developments, for example, the creation of educational tools, like textbooks, and institutions, like schools.
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 knowledge from one generation to the next. 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 happened in the form of training scribes and priests and covered various subjects besides reading and writing, including the humanities, science, medicine, mathematics, law, and astrology. 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.
In the medieval period, religious authorities had a lot of influence over formal education. This applied specifically to the role of the Catholic Church in Europe. But it is also seen in the Muslim world. Education there focused on the study of the Quran and its interpretations but also included knowledge of the sciences and the arts. Additionally, this period saw the establishment of universities as concentrated centers of higher education and research. The first universities were the University of Bologna, the University of Paris, and Oxford University. Another key development was the creation of guilds. Guilds were associations of skilled craftsmen 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.
The invention and popularization of the printing press in the middle of the 15th century by Johann Gutenberg had a profound impact on general education. It significantly reduced the cost of producing books, which were hand-written before, and thereby augmented the dissemination of written documents, including new forms like newspapers and pamphlets. The increased availability of written media had a significant influence on the general literacy of the population.
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. Aztec 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. Initiatives to promote public education and universal access to education made significant progress in the 20th and the 21st centuries and were promoted by intergovernmental organizations like the UN. Examples include the Universal Declaration of Human Rights, the Convention on the Rights of the Child, the Education for All initiative, the Millennium Development Goals, and the Sustainable Development Goals. These efforts resulted in a steady rise of all forms of education but affected primary education in particular. In 1970, 28% of all primary-school-age children worldwide did not attend school while by 2015, this number dropped to 9%.
A side effect of the establishment of public education was the introduction of standardized curricula for public schools as well as standardized tests to assess the students' progress. It also affects teachers by setting in place institutions and norms to guide and oversee teacher training, like certification requirements for teaching at public schools.
A further influence on contemporary education was the emergence of new educational technologies. 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 all around the world had to close for extended periods and many offered remote learning through video conferencing or pre-recorded video lessons to continue instruction. A further contemporary factor is the increased globalization and internationalization of education.
