Which of the following activities can help a teacher inculcate social and moral values among students?

Active participation in co-curricular activities best inculcates social and moral values, because values are learnt by doing and interacting.

Delivering lectures on values (A) gives verbal information but rarely changes conduct.

Showing television programmes (B) is passive and does not guarantee internalization.

Observing religious festivals (D) exposes learners to traditions but is occasional and narrow.

Values are acquired through experience, cooperation and social interaction rather than preaching.

Co-curricular activities nurture the affective domain (Krathwohl) of attitudes and values.
