This document compares formal education and extension education. Formal education typically starts with theory and ends with practical application, follows a fixed curriculum, and has compulsory class attendance. Extension education, on the other hand, starts with practical problems farmers face and ends with theoretical understanding, has no fixed curriculum, and involves voluntary participation. The key differences are that formal education is more theoretical and rigid, while extension education is more flexible, practical, and intended to immediately solve local problems based on community needs.
