Investigated the effects of group size and exposure time in the use of a commercially prepared tutorial program or drill-and-practice software by 168 fifth and sixth graders. Found that exposure time was related to students' scores on posttests. Results suggested a need to examine allocated time in microcomputer learning situations. (LB)

Discussion of computer literacy, database technology, and higher-order thinking skills focuses on a study that compared the problem-solving performance of fourth-grade students receiving search strategy training during computer-assisted instruction with students who did not receive training. Time spent on problems and the number of correct answers…

Describes a study that compared the effects of cooperative and individual learning on fifth and sixth grade student performance and attitudes during interactive videodisc instruction for science. The use of heterogeneous ability groups is discussed, time on task is examined, and further research is suggested. (22 references) (LRW)

This paper reports on a study investigating the effects of studying alone or in cooperative-learning groups on the performance of high and low achievers. The effects of completing computer-based instruction using either learner or program control are also examined. A total of 92 sixth-grade students were classified by Stanford Achievement Scores…
