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…

This study examined the effects of animation and practice on factual and application learning in computer based instruction (CBI), and the extent to which animation and practice promoted near and far transfer of these learning outcomes. Subjects were 192 fourth, fifth, and sixth graders, and the CBI content was an elementary physics lesson in…

Describes study of fourth and fifth grade students which explained the effect of graphics on student motivation in a microcomputer-based spelling drill program. The role of feedback in instruction is discussed, the impact of graphics on computer software is described, and results are analyzed. (4 references) (LRW)

Examined how exposure to a program of fractal computer graphics affected the perceptual sensitivity of sixth-grade students (n=197) to the natural visual environment. MANCOVA analysis of collected data and students' written responses to questions indicated that environmental perceptual sensitivity was higher for subjects exposed to fractal images.…

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 examine the effects of animated instruction and levels of practice on application learning in a computer-based instructional (CBI) science lesson. A total of 119 fourth and fifth grade students participated in an introductory lesson covering Newton's Laws of Motion. Three levels of visual elaboration (static…

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)

Describes a study that investigated the effects of visual display within a college computer-based learning program that taught computer programming language through analogies. Three types of visual displays (text, static graphics, and animation) are compared, and assessment measures that included posttests and attitude questionnaires are…

Reports on a study investigating the effects of conceptual models (computer graphics and animation) on learning and transfer of code evaluation and generation skills of novice programmers; changes in declarative knowledge during skill acquisition; relationships between the quality of subjects' mental models and performance in skill learning and…

Describes a multimedia program for teaching analysis of variance (ANOVA) designs. The program uses colorful images, brief animations, interactive tasks, and immediate feedback. It consists of 10 story problems that tests students' understanding of independent groups and repeated measures variables. Provides information about availability. (MJP)

The effects of different types of feedback in computer assisted instruction were studied in 30 college students with different cognitive styles. The program, written in Apple Pilot and administered on an Apple IIE microcomputer, consisted of 16 problem solving tasks; for each, a graphic display and a textual question were presented. Two feedback…
