Question 10

Accepted Answer

C. Jerome Bruner — Bruner's theory emphasizes discovery learning, where students actively engage with materials and problems to construct their own understanding. By allowing students to experiment and formulate hypotheses, the teacher is facilitating this active, hands-on process, which is a cornerstone of Bruner's approach. Ausubel focuses on meaningful reception learning, Vygotsky on social interaction, and Piaget on stages of cognitive development through individual exploration.
