This document reports an experiment designed to assess the effects of learner control over the level of challenge in computer-assisted instruction (CAI) and collect data that will guide the design of future learner control experiments. The subjects were 78 undergraduate students in the College of Education at a large public university. The CAI…

Part of an overall evaluation study of the WANDAH Project at Logan High School (Utah), this study compared the time on task of students in a computer-based English class in two conditions, the handwriting condition (any situation in which they were not involved with computers) and the computer condition. Observational techniques were used to code…

Describes a study conducted by the Department of Defense Polygraph Institute for their forensic science curriculum that investigated the effects of computer-based instruction on student learning of psychophysiological detection of deception test question formulation. Treatment of the experimental and control group is explained and posttest scores…

This study manipulated the timing and control of error feedback in problem solving and examined their effects on skill acquisition by 40 undergraduate students learning to program in the computer language Lisp under four error feedback conditions. These four conditions included two types of symbol-by-symbol feedback that vary in content, a…

A computer-assisted instruction (CAI) program using Utah PILOT programming language was constructed that includes the same objectives that are taught during the presentation of a traditional library tour. The amount of time necessary to complete the CAI program is approximately the same time needed by a student taking a library tour. The…

Describes a study of college students that was conducted to investigate the effect of two review strategies on the recall of information from an interactive video program. Treatments for the active review group, the passive review group, and the control group are described. Recall posttests and amount of time required to complete the instruction…

Describes a study of undergraduates in a biology course for nonmajors that examined the effects of four methods of immediate corrective feedback during computer-based instruction (CBI). The relationship between types of corrective feedback and types of errors made by learners during CBI and during a later retention test is also examined. (33…

Although both learner control and feedback have been heavily researched, very little research has been conducted on giving learners control over the feedback which they receive. The purpose of this study was to examine the effect of learner control of feedback in a computer assisted instruction (CAI) lesson. The independent variables were type of…

Intended to aid in the design of computer systems that promote efficient learning and performance, this study compared the effects of using hard copy and online format tutorials on the learning activities of 48 undergraduate students in either design or engineering. The tutorials, which provided instruction on the use of the equipment and basic…

This research project was designed to explore ways of making computer text presentations more readable as a way of compensating for the constraints that computers impose on the display of text as compared with print-on-paper displays, e.g., limited screen resolution and display area. Forty-eight undergraduate teacher education majors enrolled in…

Describes a study of 80 undergraduate foreign language learners that compared the use of a hyper-reference source incorporating an electronic dictionary and a conventional paper dictionary. Measures of consultation frequency, study time, efficiency, and comprehension are examined; bilingual and monolingual dictionary use is compared; and further…

Discussion of various types of feedback used in computer-assisted instruction focuses on a study of low-ability eleventh graders that compared the effectiveness of answer until correct (AUC) feedback with knowledge of correct response (KCR) feedback. Achievement data on posttests as well as time data are analyzed. (11 references) (LRW)

This study examined the effectiveness of a computer algebra system in teaching secondary school mathematics. Pre- and posttest results and time on task were compared for students receiving conventional instruction and those receiving computer-assisted instruction using an enhanced version of muMath, a standard computer algebra package. (four…

Presents a meta analysis which examines results of 254 controlled evaluation studies that compared student learning in classes taught with and without computer-based instruction (CBI). Outcome measures are described, statistical analysis and effect size are discussed, and results are reported that show that CBI usually produces positive effects on…

The Memphis Apple Classroom of Tomorrow (ACOT), one of seven ACOT locations, was a joint project of the city schools and Apple Computer. The ACOT consisted of a class of 30 fifth grade students in an inner city school, who were selected on the basis of the willingness of the students and their parents to participate and to use computers in the…
