[edit] Dale's Cone Misrepresented with Numbers

Edgar Dale's Cone of Experience is often misrepresented by those who add numbers to the cone. Hundreds, if not thousands, of misrepresentations have been created. In fact, this very entry had two such misrepresentations on 11-11-2007 when they were erased. See the following webpage for (1) some of the most common misrepresentations, (2) an image of Dale's original cone, and (3) citations.
