Edgar Dale developed the Cone of Experience in 1946 to show the progression of learning from concrete to abstract experiences. At the base is direct experience where learners have control over outcomes using their senses. Moving up are progressively more abstract experiences like demonstrations, exhibits, and symbolic representations using visual or verbal symbols. The Cone was intended to depict how instructional methods relate to learning outcomes and that different experiences on the Cone are not hierarchical but allow for more abstract thought. It is often misused by assuming experiences must follow the Cone from bottom to top or that some experiences are inherently better.
