Edgar Dale developed the Cone of Experience to show the relationship between how information is presented in instruction and learner outcomes. At the base of the cone are more concrete experiences like direct participation. As the cone narrows, experiences become more abstract, ending with symbolic representations using words and symbols. The cone was influenced by theories that learning progresses from concrete to abstract. It is often misinterpreted as requiring instruction to always move from bottom to top, but Dale intended it as a tool to help teachers select effective media to move students between concrete and abstract understanding.
