person, children and youth included, has a different learning style and pace and each person, is unique, not only capable of learning but also capable of succeeding. These schools assert that applying the medical model of problem-solving to individual children who are pupils in the school system, and labeling these children as disabled—referring to a whole generation of non-standard children that have been labeled as dysfunctional, even though they suffer from nothing more than the disease of responding differently in the classroom than the average manageable student—systematically prevents the students' success and the improvement of the current educational system, thus requiring the prevention of academic failure through intervention. This, they clarify, does not refer to people who have a specific disability that affects their drives; nor is anything they say and write about education meant to apply to people who have specific mental impairments, which may need to be dealt with in special, clinical ways. Describing current instructional methods as homogenization and lockstep standardization, alternative approaches are proposed, such as the Sudbury model schools, an alternative approach in which children, by enjoying personal freedom thus encouraged to exercise personal responsibility for their actions, learn at their own pace rather than following a chronologically-based curriculum. These schools are organized to allow freedom from adult interference in the daily lives of students. As long as children do no harm to others, they can do whatever they want with their time in school. The adults in other schools plan a curriculum of study, teach the students the material and then test and grade their learning. The adults at Sudbury schools are "the guardians of the children's freedom to pursue their own interests and to learn what they wish," creating and maintaining a nurturing environment, in which children feel that they are cared for, and that does not rob children of their time to explore and discover their inner selves. They also are there to answer questions and to impart specific skills or knowledge when asked to by students. As Sudbury schools, proponents of unschooling have also claimed that children raised in this method do not suffer from learning disabilities, thus not requiring the prevention of academic failure through intervention. "If learning is an emergent phenomenon, then the teacher needs to provide stimulus — lots of it – in the form of “big” questions. These must include questions to which the teacher, or perhaps
