This study investigated whether achievement, completion rate, and lesson time vary with computer-screen layouts using good design principles compared with poorly designed screens. Results with adult learners using computer-based instruction showed no difference in achievement scores but good design did lead to higher completion rates and less time…

Describes a study of undergraduates that examined the potential trade-off in study efficiency and breadth of learning for hypertexts studied by selecting units from a content map. Compares study strategies and text recall with a more- and less-segmented hypertext and discusses text representations, study times, knowledge representation, and…

Reports on a comparative assessment of a multimedia learning environment based on a guided discovery approach called CORE (Concept Object Refinement Expression) with two control conditions, lecture and electronic book, in an undergraduate radiography course. Discusses results of qualitative and quantitative measures of effectiveness, pretests 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…

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…
