Summarizes the results of five studies dealing with screen design for computer-based instruction (CBI) and provides suggestions for their application as well as future directions for research. Chunking, text density, and screen density are discussed as variables in screen design, and current research is described. (33 references) (LRW)

Discussion of the optimization of the instruction of concepts emphasizes theories of cognitive psychology. The development of instruments to record the mastery of concepts by fifth graders is described, variables of both instruction and learning are discussed, and a field experiment that compared the effectiveness of video directed instruction and…

Discussion of reading strategies focuses on a study of high school students that used three presentation modes via computer, with and without explanations about the value of text review. Highlights include pretests and posttests, student characteristics, test anxiety, prior knowledge, and implications for aptitude treatment interaction research…

Describes research with Dutch secondary school students that studied the effects of the presentation of more general (superordinate) concepts on the attainment of basic concepts, and the effects of two different forms of example presentation on concept learning. Computer based instruction and interactive video used in the study are described. (18…

Summarizes three research studies on text and screen density variables in a computer based instruction (CBI) lesson. The first two studies investigated the effectiveness of low density text on lessons taught in print and CBI modes; the third study examined learner preferences for different screen densities.
