The purpose of this study was to determine the effects of three electronic text variables (run-around, wrap-around, and transparent text) on reading speed and comprehension. One hundred thirty-two undergraduate students in an introductory computer literacy course at a major university were asked to read one of three randomly-distributed passages…

The first part of this document is the final report of a research project (1984-1989) on designing and implementing an intelligent multimedia tutoring system for repair tasks. The problem/goal and approach, equipment and implementation, experimental work, and results are discussed for three phases of research: (1) developing and testing an…

Describes a study of undergraduates that examined the effects on retention of the screen location of information displayed in computer-assisted instruction (CAI) for Spanish. Three treatment groups are described: (1) text was relevant to graphical information; (2) text was at the upper middle section of the screen; and (3) text was random. (32…

The relative effectiveness of digital versus photographic images was examined with 96 college students as subjects. A 2x2 balanced factorial design was employed to test eight hypotheses. The four groups were (1) digitized black and white; (2) digitized pseudocolor; (3) photographic black and white; and (4) photographic realistic color. Findings…

Describes the development of interactive, multimedia courseware based on Josef Alber's book, "Interaction of Color." Alber's ideas and teachings on the perceptions of color are explained, and steps involving computer graphics, hardware, and software that resulted in the use of CD-ROM and videodisc with an Apple Macintosh II are detailed.…

This investigation of the use of white space in print-based, computer-generated text focused on the point at which the white space interferes with reading speed and comprehension. It was hypothesized that reading speed and comprehension would be significantly greater when text was wrapped tightly around the graphic than when it had one-half inch…

Reports on a study of university students that evaluated presentation styles in computer-assisted learning (CAL) and computer-based training (CBT) programs. Monochrome and colored textual presentations are compared, differences between computer-naive and computer-literate users are explored, and implications for the design of CAL and CBT programs…

The purpose of this study was to examine the effects of different levels of visual elaborations and practice on application learning of adults in a computer-based science lesson. A total of 141 university students participated in an introductory lesson covering Newtonian mechanics. Three levels of visual elaboration (static graphic, animated…

The purpose of this study was to adapt the Hidden Figures Test (a measure of field dependence/independence) to microcomputer display and to assess its alternate form reliability when compared to a paper and pencil test. Participants included 58 undergraduate and graduate students (91.4% female) at a southeastern university who were fairly normal…
