The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

Summarizes three experiments examining the ways that various forms of feedback influence children's progress in learning to tell time through computer-based training. The experiments compared different forms of feedback as well as delays in their presentations. Reviews related literature and includes statistical and tabular data. (MJP)

Discusses standards developed by the Educational Computer Service of the National Education Association that incorporate technical, educational, and documentation components to guide authors in the development of quality educational software. (Author/MBR)

Describes performance criteria for users of computer assisted instruction (CAI) that are used to provide users with feedback about their performance relative to other users. This study evaluated 146 novice users on their percentages of correct responses, time required for completion, and number of times the CAI tutorial was performed. (LRW)

Suggests a method of integrating user performance and attitudes toward the computer system into quality control procedures (QCP) and describes an application of user attitudes to the QPC in a class of novice computer users receiving instruction in BASIC programing language via formal classroom lecture with computer assisted instruction tutorials.…

This study investigated the effects of integrated computer based instruction (CBI) practice on criterion task performance and attitudes of learners. The 22 subjects--11 in a treatment group and 11 in a control group--were 16 Boston College undergraduate and graduate students and 6 professional instructional designers of computer based instruction.…

This study investigated the utility of aptitude and learning rates for initial study units as predictors of time-to-mastery in an individualized, mastery-based course taught largely by TICCIT (Time-Shared, Interactive, Computer-Controlled Information Television) computer assisted instruction. A TICCIT student station includes a color television, a…

Describes a study of second, third, and fourth grade children in Israel to determine if computer assisted instruction is utilized differently by different groups of students (younger and older), and extent to which effort expenditure (total amount of time a child is engaged at the computer) is related to achievement. (MBR)

This paper summarizes research in modern cognitive theory that relates to the role of computer drill and practice programs in learning and describes a prototype program that exemplifies recommended characteristics. Focus is on four major issues that are relevant to the design and optimization of computer drills: interference, spaced practice,…

The effects of three types of pacing in microcomputer-based instructional programs were examined by evaluating learning competency on five achievement tests ranging in difficulty from memorizing facts to solving problems. Subjects were 100 first-term freshmen enrolled at Ohio State University who completed a microcomputer program on heart…

Reviews literature on computer-based training in industry over 20 years. Studies reviewed are organized by training application into three groups--basic computer-assisted instruction systems, supplemented computer-assisted instruction with simulation and graphics modes, and simulators. Time savings, user attitudes, cost savings, and performance…

Describes two studies which examined crucial factors in learner support for computer-assisted learning. Douglas investigated the effectiveness of a computerized learner support system with a group of college students, while Lebel used 15- to 17-year-old mathematics students to study the sociostructure (who works with whom and under what social…

This study explored the relationship between traditional item difficulty and cognitive complexity as measured by response time. Rural students (n=43) responded to computer-based tests of the Individualized Study by Technology General Mathematics Course developed by Alaska's Department of Education. Results indicated that mean response times were…

The purpose of this study was to examine the effects of behavioral and cognitive organizing strategies and varied processing intervals on factual and inferential learning. A total of 49 upper-division undergraduate and graduate students, who were randomly assigned to either a cognitive, behavioral, or individual orienting strategy group, received…

This study was conducted to test three hypotheses: that moderate levels of external pacing of a microcomputer instructional program would result in more effective learning; that moderate levels of external pacing would improve learning time efficiency; and that lower achievers may have to be forced into further instruction.
