Constructivist approach suggests that _________ is crucial for constructing knowledge.

Constructivism, based on Piaget's and Vygotsky's work, holds that learners construct new knowledge by connecting it to their existing prior knowledge and experiences. Prior knowledge serves as the foundation onto which new concepts are integrated. Conditioning is behaviorist, punishment is a behaviorist control mechanism, and rote memorization represents transmission-model learning, all of which contradict constructivist principles.
