Read the following statements and choose the correct option :
Assertion (A) : Jean Piaget and Lev Vygotsky differ in their perspective on the influence of language on cognitive development in children.
Reason (R) : In discovery learning, teacher provides opportunities and students derive information for themselves.

The correct answer is: Both (A) and (R) are true, but (R) is not the correct explanation of (A).

Analysis of Assertion (A):
Jean Piaget and Lev Vygotsky held distinctly different views regarding the relationship between language and cognitive development:

• Jean Piaget believed that cognitive development precedes language development. According to Piaget, thought is primary, and language is merely a vehicle for expressing thought or a reflection of cognitive development. He viewed egocentric speech in young children as a sign of cognitive immaturity that gradually disappears as the child becomes less self-centered.
• Lev Vygotsky, on the other hand, posited that language plays a fundamental role in shaping cognitive development. He emphasized social interaction and argued that language is the primary tool for thought construction. Vygotsky viewed egocentric speech (private speech) as an essential transitional tool for self-regulation and problem-solving, which eventually becomes internalized as inner thought.

Analysis of Reason (R):
Discovery learning is a constructivist teaching approach (often associated with Jerome Bruner and child-centered education) where the teacher acts as a facilitator providing rich environments, resources, and opportunities, while students actively explore, experiment, and derive key concepts and information for themselves.
Therefore, Reason (R) is true.

Relationship between Assertion (A) and Reason (R):
Although both statements are factually correct statements in educational psychology, Reason (R) describes the mechanism of discovery learning, which does not explain why Piaget and Vygotsky differ in their theories on language and cognitive development.
Hence, Reason (R) is not the correct explanation of Assertion (A).
