An ambiguity in Gagne and Briggs' model of instructional design was investigated using treatments which contrasted verbal expository and guided discovery forms of presentation. Analysis found the guided discovery method as effective as the expository method on all measures. Implications are discussed. (Author/MT)

Argues that mental images have functional properties similar to those of audiovisual media in that they can be intentionally and systematically used as the informational base for cognitive operations and as an aid to new learning. Experimental evidence is cited to support the claims. Nineteen references are cited. (Author/CHC)

Discussion of instructional materials design highlights perceptional modality preferences. Research on perception is reviewed; preferences for audio versus video, verbal versus pictorial, and listening versus reading are described; learning styles are considered; and theoretical and practical implications for audiovisual designers are suggested.…

This first installment in a series of edited transcripts based on a conference held at Utah State University in 1987 reviews the main points of Gagne's Learning Theory. Categories of human performance that are discussed include verbal information, intellectual skills, cognitive strategies, attitudes, and motor skills. (Three references) (LRW)

Describes a technology of text display that can help to make learning from text more effective. Topics discussed include the effect of text displays on the ways learners process information; implications of these effects for instructional design; and how text displays join with text content to help with verbal, experiential, and visual processing.…

Discusses individual perceptional modality preferences, including verbalization versus visualization, reading versus listening, and audio versus video. Literature on perception and on mental representation and learning styles is reviewed, and theoretical and practical implications for instructional materials design are suggested, including the use…

Describes two experiments in which high school students who studied a map/prose combination expected either a spatial/locational or verbal/event posttest. Results indicate test expectation instructions significantly influenced kinds of information students were able to recall, and type of preinstructional expectation had a pronounced effect on how…

Describes study that examined kindergarten and second grade students' recall of information that had been presented on a computer with varying levels of visual action and verbal labels. Developmental differences in children's use of verbal and visual systems are discussed, and reading ability levels are considered. (29 references) (LRW)

This study examined: (1) the effectiveness of integrating verbal elaboration (metaphors) and different visual presentation strategies (still and animated graphics) in learning biotechnology concepts; (2) whether the use of verbal elaboration with different visual presentation strategies facilitates cognitive processes; and (3) how students employ…
