Jerome Bruner's theory emphasizes that learning is an active process where students construct new ideas from existing knowledge, requiring instruction that is relevant, structured, and facilitates deeper understanding. His cognitive development framework includes three stages: enactive, iconic, and symbolic, recommending a spiral curriculum that escalates in complexity to aid learning. Bruner advocates for discovery learning, encouraging learners to engage actively with information through problem-solving, intuition, and collaboration, while also emphasizing the teacher's role as a facilitator rather than a mere provider of knowledge.
