This document discusses Edgar Dale's Cone of Experience, which illustrates how different types of instructional methods can influence learning retention rates. It presents the Cone of Experience as having 11 bands of experiences ranging from concrete to abstract: (1) Direct experiences allow for 90% retention rates while (2) reading allows only 10%. The Cone also represents a progression from easy to difficult as it moves up levels of abstraction. Using a variety of instructional methods that incorporate different sensory modes can help develop higher-order thinking skills in students.
