The Synectics Model is an approach to developing creativity designed by William J.J. Gordon that involves joining together different and unrelated elements. It uses integration of diverse individuals in a group setting to engage in creative problem solving and metaphorical thinking. The model has four key characteristics: creativity can be learned, the creative process is understandable, invention is similar across fields, and individual and group creativity are alike. The Advance Organizer Model of Teaching proposed by Ausubel links new information to prior knowledge to facilitate learning through meaningful connections between concepts. It requires well-organized material and a competent teacher to guide differentiation of new and old knowledge.
