Excellent Review of Dale's Cone and its Bastardizations

Judith Gustafson just left an excellent comment on an earlier blog post. She let us know about a presentation at the Association of (AECT) Educational Communications and Technology conference in 2002.

Click here for the PPT presentation by Tony Betrus and Al Januszewski of the State University of New York at Potsdam that does a great job of describing what Edgar Dale meant to convey with his cone, AND shows numerous examples of how the cone has been used improperly with the numbers added.

Here is my original post on this.

Since I read this post and responded, according to Dale I'll remember 37.5%, right?

Great article. It brought to my mind Gardner's work on learning intelligences, and issues such as dyslexia - presumably these statistics cited in so much research are representing "average" retention rates of a large population. I'd love to know how they were reached!

Thank you for the work you do. I wish you'd talk to my district. They show us that cone at just about every professional development meeting we attend.

Will, many thanks for continuing on the case with this myth. I wrote it up for the UK training site Training Zone (http://www.trainingzone.co.uk/cgi-bin/item.cgi?id=185067) - referencing your work and questioning why the learning profession seems to love these myths so much.
