Discussion of limiting response time for students' answers focuses on a study of Israeli elementary students that investigated the effects on their performance of increasing the response time in computer-assisted instruction (CAI) for arithmetic drill and practice. Effects on high- versus low-aptitude students, and younger versus older, are…

A randomized pre-posttest control group design was used with 34 university students in consumer economics to investigate aptitude-treatment interaction under a computer assisted instruction (CAI) and text mode of programmed instruction. Findings indicated a relative advantage of CAI for the lower aptitude student. Sixteen references are listed.…

Describes changes in cognitive correlates of learning as naval trainees advanced through a computer-managed series of hierarchical instructional modules requiring mastery-learning in electronics. The 24 cognitive characteristic tests measuring cognitive styles, abilities, and attitudes are listed as well as the content of the 11 modules and the…

Describes a study to determine effects of computer-assisted instruction (versus a text mode of programed instruction) and locus of control on preservice elementary teachers' computer literacy achievement. Differences in test scores of externally controlled individuals favored CAI. There were no differences between treatments when internally…

Discussion of the effects of group aptitudes on achievement during small group learning highlights two studies that examined the effects of group composition on high and low aptitude college students. Heterogeneous and homogeneous aptitude groups are described, and an individual mastery contingency in the second study is explained. (21 references)…

This study investigated the effect of reward structure and group ability composition on small group computer-assisted instruction. Junior high school students practiced algebra in mixed-ability or uniform-ability groups, and rewards were based on individual performance, group performance, or a combination of both.

Describes study of Israeli elementary school students that examined student attitudes toward computer-assisted instruction (CAI) designed to provide drill and practice in arithmetic. Attitudes are compared in relation to students' aptitude, gender, grade level, and socioeconomic status, and implications for the design of CAI systems are discussed.…
