Concept:Social constructivism emphasizes learning through interaction, discussion, and using context to build understanding.
Explanation:In a social constructivist approach, students actively construct knowledge with peers and teachers.
(i) Salma uses flashcards and rewards – this is behaviourist, not constructivist.
(ii) Pramati lets students choose books and discuss them regularly – this promotes social interaction and shared meaning.
(iii) Arundhati uses contextual material to figure out word meanings – this helps students build understanding from context.
(iv) Rekha makes students write misspelled words five times – this is rote memorisation, not constructivist.
So only (ii) and (iii) fit the social constructivist model.
