Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, morals, beliefs, habits, and personal development. Educational methods include teaching, training, storytelling, discussion and directed research. Education frequently takes place under the guidance of educators; however, learners can also educate themselves. Education can take place in formal or informal settings, and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy.

Formal Education occurs in a structured environment whose explicit purpose is teaching students. Usually, formal education takes place in a school environment with classrooms of multiple students learning together with a trained, certified teacher of the subject. Most school systems are designed around a set of values or ideals that govern all educational choices in that system. Such choices include curriculum, organizational models, design of the physical learning spaces (e.g. classrooms), student-teacher interactions, methods of assessment, class size, educational activities.

The International Standard Classification of Education (ISCED) was created by UNESCO as a statistical base to compare education systems. In 1997, it defined 7 levels of education and 25 fields, though the fields were later separated out to form a different project. The current version ISCED 2011 has 9 rather than 7 levels, created by dividing the tertiary pre-doctorate level into three levels. It also extended the lowest level (ISCED 0) to cover a new sub-category of early childhood educational development programmes, which target children below the age of 3 years.

Early Childhood Education designed to support early development in preparation for participation in school and society. The programmes are designed for children below the age of 3. This is ISCED level 01. Preschools provide education from ages approximately three to seven, depending on the country when children enter primary education. The children now readily interact with their peers and the educator. These are also known as nursery schools and as kindergarten, except in the US, where the term kindergarten refers to the earliest levels of primary education. Kindergarten “provides a child-centred, preschool curriculum for three- to seven-year-old children that aim at unfolding the child’s physical, intellectual, and moral nature with balanced emphasis on each of them.” This is ISCED level 02.

Primary Education This is ISCED level 1. Primary (or elementary) education consists of the first four to seven years of formal, structured education. In general, primary education consists of six to eight years of schooling starting at the age of five to seven, although this varies between, and sometimes within, countries. Globally, in 2008, around 89% of children aged six to twelve were enrolled in primary education, and this proportion was rising.[full citation needed] Under the Education For All programs driven by UNESCO, most countries have committed to achieving universal enrollment in primary education by 2015, and in many countries, it is compulsory. The division between primary and secondary education is quite arbitrary, but it generally occurs at about eleven or twelve years of age. Some education systems have separate middle schools, with the transition to the final stage of secondary education taking place at around the age of fifteen. Schools that provide primary education, are mostly referred to as primary schools or elementary schools. Primary schools are often subdivided into infant schools and junior schools.

Secondary Education: This covers the two ISCED levels, ISCED 2: Lower Secondary Education and ISCED 3: Upper Secondary Education.

In most contemporary educational systems of the world, secondary education comprises the formal education that occurs during adolescence. In the United States, Canada, and Australia, primary and secondary education together are sometimes referred to as K-12 education, and in New Zealand Year 1–13 is used. The purpose of secondary education can be to give common knowledge, to ensure literacy, to prepare for higher education, or to train directly in a profession.

Secondary education in the United States did not emerge until 1910, with the rise of large corporations and advancing technology in factories, which required skilled workers. In order to meet this new job demand, high schools were created, with a curriculum focused on practical job skills that would better prepare students for white collar or skilled blue collar work. This proved beneficial for both employers and employees, since the improved human capital lowered costs for the employer, while skilled employees received higher wages.

Secondary education has a longer history in Europe, where grammar schools or academies date from as early as the 6th century, in the form of public schools, fee-paying schools, or charitable educational foundations, which themselves date even further back.

It spans the period between the typically universal compulsory, primary education to the optional, selective tertiary, “postsecondary”, or “higher” education of ISCED 5 and 6 (e.g. university), and the ISCED 4 Further education or vocational school.

Depending on the system, schools for this period, or a part of it, may be called secondary or high schools, gymnasiums, lyceums, middle schools, colleges, or vocational schools. The exact meaning of any of these terms varies from one system to another. The exact boundary between primary and secondary education also varies from country to country and even within them but is generally around the seventh to the tenth year of schooling.

Lower Programs at ISCED level 2, lower secondary education are usually organized around a more subject-oriented curriculum; differing from primary education. Teachers typically have pedagogical training in the specific subjects and, more often than at ISCED level 1, a class of students will have several teachers, each with specialized knowledge of the subjects they teach. Programmes at ISCED level 2, aim to lay the foundation for lifelong learning and human development upon introducing theoretical concepts across a broad range of subjects which can be developed in future stages. Some education systems may offer vocational education programs during ISCED level 2 providing skills relevant to employment.

Upper Programs at ISCED level 3, or upper secondary education, are typically designed to complete the secondary education process. They lead to skills relevant to employment and the skill necessary to engage in tertiary courses. They offer students more varied, specialized and in-depth instruction. They are more differentiated, with range of options and learning streams.

Community colleges offer another option at this transitional stage of education. They provide nonresidential junior college courses to people living in a particular area.

Higher education, also called tertiary, third stage, or postsecondary education, is the non-compulsory educational level that follows the completion of a school such as a high school or secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities mainly provide tertiary education. Collectively, these are sometimes known as tertiary institutions. Individuals who complete tertiary education generally receive certificates, diplomas, or academic degrees.

The ISCED distinguishes 4 levels of tertiary education. ISCED 6 is equivalent to a first degree, ISCED 7 is equivalent to a masters or an advanced professional qualification and ISCED 8 is an advanced research qualification, usually concluding with the submission and defence of a substantive dissertation of publishable quality based on original research. The category ISCED 5 is reserved for short-cycle courses of requiring degree level study.

Higher education typically involves work towards a degree-level or foundation degree qualification. In most developed countries, a high proportion of the population (up to 50%) now enter higher education at some time in their lives. Higher education is therefore very important to national economies, both as a significant industry in its own right and as a source of trained and educated personnel for the rest of the economy.

University education includes teaching, research, and social services activities, and it includes both the undergraduate level (sometimes referred to as tertiary education) and the graduate (or postgraduate) level (sometimes referred to as graduate school). Some universities are composed of several colleges.

Vocational education is a form of education focused on direct and practical training for a specific trade or craft. Vocational education may come in the form of an apprenticeship or internship as well as institutions teaching courses such as carpentry, agriculture, engineering, medicine, architecture and the arts. Post 16 education, adult education and further education involve continued study, but a level no different from that found at upper secondary, and are grouped together as ISCED 4, post-secondary non-tertiary education.

Special education In the past, those who were disabled were often not eligible for public education. Children with disabilities were repeatedly denied an education by physicians or special tutors. These early physicians (people like Itard, Seguin, Howe, Gallaudet) set the foundation for special education today. They focused on individualized instruction and functional skills. In its early years, special education was only provided to people with severe disabilities, but more recently it has been opened to anyone who has experienced difficulty learning.

In India, for example, compulsory education spans over twelve years, with eight years of elementary education, five years of primary schooling and three years of upper primary schooling. Various states in the republic of India provide 12 years of compulsory school education based on a national curriculum framework designed by the National Council of Educational Research and Training.

Informal learning is one of three forms of learning defined by the Organisation for Economic Co-operation and Development (OECD). Informal learning occurs in a variety of places, such as at home, work, and through daily interactions and shared relationships among members of society. For many learners, this includes language acquisition, cultural norms, and manners.

In informal learning, there is often a reference person, a peer or expert, to guide the learner. If learners have a personal interest in what they are informally being taught, learners tend to expand their existing knowledge and conceive new ideas about the topic being learned. For example, a museum is traditionally considered an informal learning environment, as there is room for free choice, a diverse and potentially non-standardized range of topics, flexible structures, socially rich interaction, and no externally imposed assessments.

Open education has been called the biggest change in the way people learn since the printing press. Despite favourable studies on effectiveness, many people may still desire to choose traditional campus education for social and cultural reasons.

Many open universities are working to have the ability to offer students standardized testing and traditional degrees and credentials.

While informal learning often takes place outside educational establishments and does not follow a specified curriculum, it can also occur within educational settings and even during formal learning situations. Educators can structure their lessons to directly utilize their students informal learning skills within the education setting.

In India, for example, compulsory education spans over twelve years, with eight years of elementary education, five years of primary schooling and three years of upper primary schooling. Various states in the republic of India provide 12 years of compulsory school education based on a national curriculum framework designed by the National Council of Educational Research and Training.

There are movements for education reforms, such as for improving quality and efficiency of education towards relevance in students’ lives and efficient problem solving in modern or future society at large, or for evidence-based education methodologies. A right to education has been recognized by some governments and the United Nations. Global initiatives aim at achieving the Sustainable Development Goal 4, which promotes quality education for all.

An education system comprises everything that goes into educating public-school students at the federal, state, or community levels. It is an arrangement that consists of at least one teacher and one student in a context, such as in a tutorial or via Skype. Education systems must be intentional, where a teacher actively attempts to guide student learning. Education systems encompass all institutions that are concerned with educating students. For students, the education system encompasses elementary school, middle school, high school and then college or university.

An education system refers to the economic and social factors that typically make up public schools at the federal, state or community levels. Such factors include public funding, school facilities, staffing, compensation, employee benefits, teaching resources and more. Education systems refer to the coordination of individuals (among teachers, administrators and students), infrastructure (including safe facilities and transportation) and functioning institutions and processes.

The world is changing at an ever quickening rate, which means that a lot of knowledge becomes obsolete and inaccurate more quickly. The emphasis is therefore shifting to teaching the skills of learning: to picking up new knowledge quickly and in as agile a way as possible. Finnish schools have begun to move away from the regular subject-focused curricula, introducing instead developments like phenomenon-based learning, where students study concepts like climate change instead. There are also active educational interventions to implement programs and paths specific to non-traditional students, such as first generation students.

Education is also becoming a commodity no longer reserved for children , adults need it too. Some governmental bodies, like the Finnish Innovation Fund Sitra in Finland, have proposed compulsory lifelong education.

Studies found that automation is likely to eliminate nearly half the jobs in developed countries during roughly the next two decades. Automation is therefore considered to be a major factor in a “race between education and technology”. Automation technologies and their application may render certain currently taught skills and knowledge redundant while increasing the need for other curricula – such as material related to the application of automation. It has been argued that formal education is “teaching workers the wrong things, and that deep reform is essential to facilitate the development of digital knowledge and technical skills, as well as nonroutine cognitive and noncognitive (or “soft”) skills” and that the formal state-organized education system – which is built on the Industrial Revolution model and focuses on IQ and memorization is losing relevance. Schools were found rarely teach in forms of “learning by doing”, and many children above a certain age “hate school” in terms of the material and subjects being taught, with much of it being a “waste of time” that gets forgotten quickly and is useless in modern society. Moreover, the material currently being taught may not be taught in a highly time-efficient manner and analyzing educational issues over time and using relevant forms of student feedback in efficiency analysis were found to be important. Some research investigates how education can facilitate students’ interest in topics – and jobs – that scientific research, data, economic players, financial markets, and other economic mechanisms consider important to contemporary and future human civilization and states.

Studies have shown that active learning rarely applied in schools is highly efficacious. Studies found that massive open online courses offer a pathway to employment that currently bypasses conventional universities and their degree programs while often being more relevant to contemporary economic activities and the students’ interests. Such online courses are not commonly part of formal education but are typically both completed and selected entirely on behalf of the student, sometimes with the support of peers over online forums. In contrast, blended learning merges online education with forms of face‐to‐face communication and traditional class-based education in classrooms, revealing itself to have the general capacity for increasingly relevant, resource-efficient and effective approaches to education. Deploying, using, and managing various tools or platforms for education typically imply an increase in economic investment. Expenses for education are often large with many calling for further increases. Potential policies for the development of international open source educational software using latest technologies may minimize costs, hardware requirements, problem-resolval efforts and deployment-times while increasing robustness, security and functional features of the software.

Covid-19 Beginning in early 2020, the COVID-19 pandemic disrupted education systems throughout the world, affecting nearly 1.6 billion learners in more than 190 countries. Closures of schools and other learning spaces have impacted 94 percent of the world’s student population, up to 99 percent in low and lower-middle income countries. Many schools made alternative plans during the pandemic, leading to a variety of in-person, hybrid, and online-only plans, which led to challenges for many students, teachers, and families including children with learning disabilities and those learning in a language that is not their native one. As of September 30, 2020 there were 27 countries that had localized school closures. In the United States, an estimated 55.1 million students were forced to cease in-person instruction as of April 10, 2020. A switch to a virtual learning experience is particularly challenging for families that cannot afford the proper technology, such as laptops, printers, or a reliable Internet connection. When schools close, parents are often asked to facilitate the learning of children at home and can struggle to perform this task. This is especially true for parents with limited education and resources. Students who require special education found it difficult to progress through the curriculum without tools and support that they require. Polling suggests that schools that serve a majority of students of color are far less likely to have access to the technology needed for remote learning

The mental health of students has been greatly impacted due to the pandemic. It is estimated that three in ten participating in school at home have had their emotional and mental health negatively impacted. Similarly, the social lives of students have also been upended and this has been detrimental to the health of students worldwide which has also negatively impacted educational quality. This will be an issue for years to come. COVID-19 has shone a light on opportunity gaps and it will be up to educators and policymakers to direct the necessary resources to mitigating them in the coming year
