The document discusses four theories of teaching and learning: behaviorism, cognitivism, constructivism, and zone of proximal development. Behaviorism focuses on conditioning and was influenced by Skinner. Cognitivism looks at internal mental states and was influenced by Piaget. Constructivism holds that students are responsible for their own learning. Zone of proximal development refers to what a learner can do with or without help and was put forth by Vygotsky.
