q2 i? Applying profile analysis before production to Human Reproduction was projected to allow a 31 percent increase in the amount of learning. → Fletcher 1955

Evidence¶

Fletcher 1955¶

Fletcher, Richard M. (1955). Profile Analysis and Its Effect on Learning When Used To Shorten Recorded Film Commentaries. Technical Report SDC Z69-7-55, Instructional Film Research Program, Pennsylvania State University. https://eric.ed.gov/?q=Fletcher+profile+analysis+film+commentaries

q2 · i? · causal · r1

Authors' projection (type e) in the recommendations: eliminating non-contributory material before production is argued to permit replacing it with material that does contribute. This is an estimate, not a measured post-intervention learning gain; no effect size is printed.

"If this had been done with the film Human Reproduction the amount of learning could have been increased by 31 percent."
