The document discusses different theories of learning including behaviorism, cognitivism, and social constructivism. Behaviorism views learning as changes in behavior from experiences and reinforcement. Cognitivism sees learning as how individuals actively construct understanding from experiences and prior knowledge through schemas. Social constructivism, influenced by Vygotsky, proposes that learning occurs through social interactions and in collaboration with more knowledgeable others in a child's zone of proximal development. Each theory provides a different perspective on the nature of knowledge, the learner's role, and implications for teaching.
