Deschooling is a term used by both education philosophers and proponents of alternative education and/or home schooling, which refers to different things in each context.
It was popularized by Ivan Illich in his 1971 book Deschooling Society.
Philosophically, it refers to the belief that schools and other learning institutions are incapable of giving the best possible education for some or most individuals. Some extend this concept beyond the individual and call for an end to schools in general. This is based on the belief that most people learn better by themselves, outside of an institutional environment, at a self-determined pace. This is the meaning of the term as used by Illich. Another common criticism is that institutionalized schooling is utilized as a tool for the engineering of an ignorant, conformist working class through constant schedules and prearranged time blocks and one-size-fits-all teaching methods.
Practical alternatives arising in place of institutionalized learning have been free schools, un schooling at home and forming networks with other deschooling families and individuals.
In a practical context, it refers to the mental process a person goes through after being disconnected from a formal schooling environment, when the “school mind set” is eroded over time. It is typically used to describe children who have been removed from school for the purpose of self-directed home schooling, but technically applies any person leaving school, either by dropping out or graduating.
Deschooling is sometimes used synonymously with un schooling, which is actually quite different. The term deschooling refers to the time period it takes for child removed from school to adjust to learning in an unstructured environment. Families who have taken their children out of school to home school often find their children need a period of adjustment- learning to live without the reinforcement of grading and regimented learning.
