The document discusses Edgar Dale's Cone of Experience, which arranges learning experiences from most concrete to most abstract. At the base are direct purposeful experiences, followed by contrived experiences like mock-ups and models. Dramatized experiences like plays are next, then demonstrations, study trips, exhibits, educational videos and films, recordings, pictures, visual symbols like diagrams, and finally the most abstract verbal symbols like written words. The cone presents a pictorial representation of different types of experiences that contribute to learning, from real-world experiences to abstract symbols.
