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…

The effect of instructional analogy training on the level of immediate, as well as 14-day delay, comprehension of tangible and intangible physiological concepts was investigated. Ninety-four college-aged subjects were given training either with or without instructional analogies over five tangible and five intangible advanced physiological…

Describes study that examined the effects of presentation sequence of examples and example difficulty on undergraduate learning with computer-based instruction. Establishing example difficulty according to a generalization formula versus subject matter experts is discussed, and effects on time on task and the number of examples required are…

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 computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 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 study of undergraduates that investigated learners' preconceptions of the difficulty of interactive video, instructional television, and television. The effects of actively or covertly responding to practice questions on perceived mental effort, recall, and inferences are examined, and correlations between lesson time and inference or…

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…

Discussion of digital audio in computer-based training (CBT) focuses on a study at the University of Central Florida that was conducted to determine whether the addition of audio to CBT had positive effects on undergraduates' cognitive achievement levels and to analyze its effect on time required to complete a lesson. (14 references) (LRW)

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…

Describes a study of undergraduate students that investigated the effects of two types of learner control and two types of incentives--task-contingent and performance-contingent--on learners' achievement, attitudes, use of options, and time on program using computer-delivered instruction. Implications for instructional design and research are…
