This document discusses three main types of education: informal, formal, and non-formal. Informal education involves lifelong learning from daily experiences and exposure to one's environment. Formal education takes place in institutions with a graded curriculum, leads to certificates or degrees, and is uniform and subject-oriented. Non-formal education is flexible, learner-centered, uses participatory teaching methods, and can occur in locations like libraries through programs like open university courses. It aims to increase knowledge and skills outside of traditional school systems.
