In response to the wide-scale proliferation of "the cone of learning"--a fanciful retention chart confounded with Dale's Cone of Experience--the authors make four major claims debunking this fantasy and provide documentary evidence to support these claims. The first claim is that the data in the mythical retention chart do not make…

Critics have been attempting to debunk the mythical retention chart at least since 1971. The earliest critics, David Curl and Frank Dwyer, were addressing just the retention data.

The authors are attempting to set the record straight regarding the sources frequently cited in the literature of the mythical retention chart and the corrupted Dale's Cone. They point out citations that do not actually connect with relevant works; provide correct citations of sources that are often cited erroneously; add references for overlooked…

Attempts to propose a cognitive process model of problem finding, operationally define problem finding, and to present empirical evidence for the proposed model. (Author/RK)

A test of the concept of horizontality was devised to examine the performance of a sample of 861 Australian school children in grades 1 to 6 tested in their classrooms. (Editor)

Summarizes and critiques Berberich's dissertation on cognitive effects on music perception. Comments on the study's unusual data analysis and presentation.
