Describes a study of undergraduates that compared three strategies for indicating links in a hypermedia system to determine their effect on learner navigation and learner perceptions of ease of use. Highlights include three linking display types; the density of links; elaboration types; time intervals; and implications for hypermedia system…

Discussion of hypertext systems and navigation focuses on a study conducted with undergraduates at Clemson University (South Carolina) that compared a hypertext browsing system with a linearly based system for accessing information concerning college transfer courses. Results indicate that user perceptions and performance are more favorable with…

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

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)

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 of undergraduates that investigated the use of hypermedia programs by learners classified as active, passive, or neutral. Two instructional approaches were compared, one utilizing instructional cues and one without instructional cues; and dependent variables including achievement, time on task, and frequency of viewing embedded…

Describes a study that compared individual computer-assisted instruction (CAI) with paired/cooperative CAI as a method of providing inservice training for cooperative extension agents on the topic of proper water well location and construction. Cognitive achievement and time spent on the lesson are investigated. (18 references) (LRW)

This study demonstrated that, although standard instructional design revisions of a traditional textbook chapter had no effect on teacher attitudes toward adoption of the material, the revised version of the chapter significantly improved student performance. Teacher and student participants in the study were from the St. Petersburg…

Describes a study that investigated the effect of curiosity on learning art education facts and concepts by first and second graders in computer-based interactive learner-controlled environments with and without advisement. Results are compared with a previous study on learner control and advisement, and implications for instructional design are…

Reports on a study investigating the importance of audio and textual redundancy in a computer-based, multimedia training program with identical content that undergraduate students used under one of the following conditions: full-text and totally redundant audio delivery; partial-text with full audio delivery; or graphics only with full audio…

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…
