The relative effectiveness of digital versus photographic images was examined with 96 college students as subjects. A 2x2 balanced factorial design was employed to test eight hypotheses. The four groups were (1) digitized black and white; (2) digitized pseudocolor; (3) photographic black and white; and (4) photographic realistic color. Findings…

Describes study of high school students that was designed to determine the relative effectiveness of color, graphics, and animation in computer assisted learning (CAL) of a mathematical rule. Three CAL modes, in color and in black and white, are compared; pretests and posttests are explained; and further research needs are suggested. (13…

A study was conducted to investigate the comprehensibility of microcomputer-generated color graphics that are displayed on monochromatic monitors. Subjects were 64 second, third, and fourth graders who were randomly assigned to one of two conditions. Children in the first treatment were asked to identify, on a monochrome monitor, a figure that was…

Discussion of the use of nonexamples as an effective strategy in teaching concepts focuses on a study of college students that explored the use of common errors to teach the procedure for color correction of color transparencies. Treatments for the experimental and control groups are described, and further research needs are indicated. (Author/LRW)
