Constructivism proposes that cognitive development occurs through active construction of knowledge by the individual, emphasising the role of prior knowledge, social interaction, and personal experiences. Behaviourism, on the other hand, suggests that cognitive development is shaped by external stimuli and reinforcement. While behaviourism provides valuable insights into the role of environmental factors, constructivism offers a more accurate account of cognitive development by recognising the active role of the individual in constructing their knowledge and understanding. Constructivism considers the importance of internal cognitive processes and personal experiences, providing a more comprehensive perspective on cognitive development.
