Bogus Research Uncovered
Work-Learning Research,
Feb 10, 2003
Last week I listed a background paper for a discussion on ITForum called Lean-In Technology, Safety Nets and Psychology . In this paper was cited the oft-repeated list of familiar teaching modes and retention rates. In the discussion that followed, this list came under closer scrutiny and a reader cited this article in which the author asserts bluntly that "the graph is a fraud." According to the author, "it appears that those percentages were probably generated by an employee of Mobil Oil Company in 1967, writing in the magazine Film and Audio-Visual Communications. D. G. Treichler didn’t cite any research, but our field has unfortunately accepted his/her percentages ever since." The original (unquantified) source of the model is probably Edgar Dale's Cone of Experience, first published in 1946.
