Cone of Experience (Edgar Dale)

Edward Dale's cone of experience was firstly introduced in his book “Audio-visual methods in teaching” published in 1946. It was an image explaining types of mediated learning experiences. The Cone was organized by starting with most abstract experiences from its top, changing to most concrete experiences at its bottom. In later editions of the book it was subjected to some minor changes, but the original cone image can be found here.

NOTE: Bogus percentage numbers have later been added to Dale's cone. They aren't however in any way related to the original Cone.
