Describes study that examined text density levels as a design variable in print and computer-based instructional presentations. The six treatment groups are explained, including low density, high density, and learner controlled density; attitude surveys and achievement posttests are described; and implications of the findings for instructional…

A comparison of the performance of two groups of third grade students practicing division problems is used to assess the effect of a commercial computer-assisted instruction drill program on learning. The progress of the experimental group (using computers) is compared with that of a group using conventional print drill practice. (20 references)…

Describes study of undergraduate teacher education majors which was designed to examine the function of text density level (high, low, or learner controlled) and various learner characteristics in learning from expository text in computer based instruction (CBI). Selection of print media versus CBI is discussed, pretests and posttests are…
