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 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, anthropology, 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 of charge, and compulsory up to a certain age. Today, over 90% of all primary-school-age children worldwide attend primary school.
Definitions
The term "education" is derived from the Latin words educare, meaning "to bring up" and educere, meaning "to bring forth". 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.
Extensive debate surrounds its exact nature beyond these general features. One approach views education as a process that occurs during events such as schooling, teaching, and learning. Another outlook understands education not as a process but as the mental states and dispositions of educated persons that result from this process.
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 matters when trying to identify educational phenomena, measure educational success, and improve educational practices.
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 forms of education are similar to one another, but they need not share a set of essential features. Some education theorists, such as Keira Sewell and Stephen Newman, hold that the term "education" is context-dependent.
Evaluative or thick conceptions 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 rationally 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 morally 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 solving problems.
Types
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 distinct levels of education based on factors like the student's age and the complexity of the content. Further categories focus on the topic, teaching method, medium used, and funding.
Formal, non-formal, and informal
The most common division is between formal, non-formal, and informal education. 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, 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 occurred informally, and there was little distinction between educational activities 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 formal education became increasingly important throughout history. 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.
Levels
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 2โ3), post-secondary non-tertiary education (level 4), and tertiary education (levels 5โ8).
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 childhood development across the physical, mental, and social domains. 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 between the ages of five and seven and lasts for four to seven years. It has no further entry requirements, and its main goal is to teach basic skills in reading, writing, and mathematics. It also covers core knowledge in other fields, such as 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 learning outcomes, is more focused on subject-specific curricula, and has teachers who specialize in only one or a few 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. Universities usually offer it as an intermediate academic certification, namely 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 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 fees 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.
Others
The academic literature discusses many other types of education and distinguishes 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. 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 schools, Escuela Nueva schools, 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 gurukul schools in India, madrasa schools in the Middle East, and yeshivas 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 to study and when, which can make it 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 courses and materials are made available with minimal barriers to access. They contrast with regular classroom or on-site 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.
Role in society
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 or can act as a driver of societal transformation. 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, write, solve arithmetic problems, and handle information and communications technology. Socialization also includes learning the dominant social and cultural norms and what kinds of behavior are considered appropriate in different contexts.
Education enables the social cohesion, stability, and peace needed for people to productively engage in daily business. Socialization happens throughout life but is of special relevance to early childhood education. 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.
