Extension education differs from formal education in its approach and setting:
- (1) is incorrect: Formal education is typically confined to institutional premises (e.g., schools, universities), whereas extension education occurs in community settings like farms, villages, or homes.
- (2) is incorrect: Formal education often involves a fixed curriculum and examinations, while extension education is flexible, tailored to learners’ needs, and typically does not include formal exams.
- (3) is incorrect: In formal education, knowledge often flows unidirectionally from teacher to student, but extension education encourages participatory learning, with two-way knowledge exchange between educators and learners (e.g., farmers sharing local expertise).
- (4) is correct: Extension education primarily takes place outside traditional classrooms, in real-world settings like agricultural fields or community centers, to deliver practical, context-specific knowledge.
Thus, option (4) is correct.
