In planning media systems for individualized study it is valuable to know if printed materials are as effective as projected materials in promoting student recall. An experiment to compare printed and projected materials utilized subjects from graduate school, the tenth, and the twelfth grade. Subjects were tested on images in either printed or projected form under controlled conditions. Projected stimuli scored higher than printed ones, but not significantly at the .05 percent level. It is concluded that in general printed images are as effective as projected ones. (RB)
