Unschooling is an informal learning method that prioritizes learner-chosen activities as a primary means for learning. Unschoolers learn through their natural life experiences including play, household responsibilities, personal interests and curiosity, internships and work experience, travel, books, elective classes, family, mentors, and social interaction. Often considered a lesson- and curriculum-free implementation of homeschooling, unschooling encourages exploration of activities initiated by the children themselves, under the belief that the more personal learning is, the more meaningful, well-understood, and therefore useful it is to the child. While unschooled students may occasionally take courses, unschooling questions the usefulness of standard curricula, fixed times at which learning should take place, conventional grading methods and standardized tests, forced contact with children in their own age group, the compulsion to do homework regardless of whether it helps the learner in their individual situation, the effectiveness of listening to and obeying the orders of one authority figure for several hours each day, and other features of traditional schooling.
