The IRT (Item Response Theory) has been studied and applied in computer-based test for decades. However, almost of all these existing studies evaluated focus merely on test questions with text-based (or static text/graphic) type of presentation form illustrated exclusively. In this paper, we present our study on test questions using both…

This study examined the effects of animated presentations on intentional and incidental learning and the degree to which computer practice activities contained intrinsically motivating characteristics as measured by continuing motivation. A total of 70 fourth graders participated in an introductory lesson on Newton's laws of motion. Two levels of…

This study compares the effectiveness of three types of computer graphics display for computer-assisted instruction in (1) low level (boxed alphanumerics and schematics), (2) medium level (line drawings), and (3) high level (line drawings plus animations). Three groups of 30 enlisted personnel at the Engineering School and the Defense Mapping…

Using PLATO, a computer-assisted instruction system, a test was conducted to see if students respond most favorably to an instructional package that included no graphic display, still graphic display, or animated graphic display. Forty-five students at the Naval Training Center, San Diego, were the subjects. With the learning of the sine-ratio…

Describes study conducted to assess the ability of first grade students to interpret and use computer-generated pictures. Differences in physical attributes between computer-generated and traditional picture formats and their effect on children's ability to interpret and process information contained in the pictures are discussed. (six references)…

Explains a social studies lesson for third graders that uses KidPix, a computer software graphics program to help students make maps and map keys. Advantages to using the computer versus hand drawing maps are discussed, and an example of map requirements for the lesson is included. (LRW)

The effects of visual grouping strategies involving animated and static graphic presentations on learning were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an animated sequence in the hope of replicating results from previous research. A total of 39 fourth graders participated in an…

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…

This paper argues that recent developments in technology hold considerable promise for distance education. Audiocassettes, audiographics (the combining of natural sound, via the telephone or audiocassettes, with computer-generated graphics), videocassettes, and computer conferencing are used as examples to identify factors that should be…

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…

This study was initiated to design, develop, implement, and evaluate a videodisc-based simulator system, the Interactive Graphics Simulator (IGS) for 6883 Converter Flight Control Test Station training at Lowry Air Force Base, Colorado. The simulator provided a means for performing task analysis online, developing simulations from the task…

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.…

Two computer assisted instruction programs tested the effects of plain and enhanced screen designs with or without information about those designs and task-type on time and learning. Subjects were 140 fourth grade students in Lincoln, Nebraska who had extensive prior experience with computers. The enhanced versions used headings, directive cues,…

Describes study of high school students that was designed to determine the relative effectiveness of color, graphics, and animation in computer assisted learning (CAL) of a mathematical rule. Three CAL modes, in color and in black and white, are compared; pretests and posttests are explained; and further research needs are suggested. (13…
