This reflects the core of Piaget's theory of cognitive development, which posits that children actively construct their understanding of the world through their experiences. According to Piaget, learning is not something that is done to a child; rather, it is something that a child does through interaction with their physical and social environments. This perspective emphasizes the active role of the learner in building knowledge and understanding, through processes such as assimilation and accommodation. Piaget's theory highlights the importance of active exploration and the construction of knowledge as key to cognitive development.
Information Booster:
(a) Piaget argued against the idea that knowledge is innate, emphasizing instead the role of environmental interaction and experiential learning in cognitive development.
(b) While Piaget acknowledged the role of social interactions in cognitive development, he did not emphasize the co-construction of knowledge with more knowledgeable others as much as later theorists like Vygotsky did, who proposed the concept of the Zone of Proximal Development.
(c) Piaget's focus was not on visible behavioral changes as indicators of learning but rather on the internal processes and stages of cognitive development, marking a shift from behaviorist perspectives on learning to constructivist ones.
