Research in the area of amount of time spent on assignments and effect on course performance has focused exclusively either on the lecture or online format, but not comparison of the two. Nowhere has both modes of delivery been studied using an objective measure of course involvement. This study examines what is most significant in predicting a…

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 the final investigation of a sequential series of studies to determine whether videodisc technology is educationally effective and cost efficient. The study compared training time, posttest success, student stress, and student satisfaction in U.S. Army paramedic students in a nonvideodisc control group and limited-access and full-access…

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…

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…

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…

Explains the combination of hypertext and knowledge maps into hypermaps, and describes a study of undergraduates learning statistical material that compared the effectiveness of using hypertext versus hypermaps. Recall, reference time and accuracy, and student satisfaction are investigated, and needs for further studies are suggested. (10…

Describes a study that compared the effectiveness of computer-mediated communication systems for teacher education distance education courses with traditional classroom instruction and a correspondence course at Purdue University. Variables examined are described, including achievement test scores, time-on-task, and students' attitudes; and…

Describes a study that compared animated demonstrations, procedural textual instructions, and demonstrations combined with spoken procedural text to assess the effectiveness of animated demonstrations for users learning HyperCard. Results of accuracy, time on task, user responses, retention, and transfer are discussed; and future research is…
