This document discusses several theories of learning, including behaviourism, constructivism, and social constructivism. It provides an overview of key theorists and perspectives within each theory. Behaviourism, associated with theorists like Pavlov and Skinner, views learning as changes in observable behaviour caused by environmental stimuli and reinforcement. Constructivism, associated with Piaget, sees learning as an active process of constructing knowledge based on mental schema and interactions with the environment. Social constructivism, developed by Vygotsky, emphasizes the social aspects of learning and the role of language and culture. The document examines evidence of each theory in modern classrooms and considers their implications for teaching approaches and views of the learner.
