Using computer graphics such as drawings, charts, and figures in textual instruction can enhance learning by providing a spatial concept of what is being read. It is important for instructional designers to determine the specific instructional objectives to be met, what level of comprehension they want learners to achieve, and how to use the…

In this article two studies on the use of diagrams in computer-supported collaborative learning are compared. Focus is on the way argumentative diagrams can be used during collaborative learning tasks, more specifically how diagrams support argumentative interaction between students when they discuss ill-defined topics. The main goal is to…

This paper extends work on the construction of instructional modules that use graphical and simulation techniques for teaching statistical concepts (Marasinghe, et al. 1996; Iversen and Marasinghe 2001). These modules consist of two components: a software part and a lesson part. A computer program written in LISP-STAT with a highly interactive…

This paper provides guidelines for designing metacognitive maps in web-based learning environments. A metacognitive map is a visual interface-based tool that supports metacognition throughout the entire learning process. Inspired by the four key metacognitive skills of planning, monitoring, evaluating, and revising, the metacognitive map is…

Animation is being used extensively for instructional purposes; however, it has not been found to be effective on measures of higher order learning (concepts, rules, procedures) within the knowledge acquisition and knowledge integration domains. The purpose of this study was to examine the instructional effectiveness of two visual scaffolding…

A study investigated effects of visuals use in interactive multimedia instruction in a college-level unit on listening skills in communication. Subjects (n=140 students) were randomly assigned to two treatment groups (use of visuals/no use of visuals). Results indicate no significant difference between groups on cognitive or listening tests…

Gives examples of classroom projects that use captioning technology and its benefits in improving language skills as well as helping students develop computer skills. Describes equipment needed. A sidebar by Vaughn Neal discusses the "ins and outs" of video editing. (AEF)

Examines the effects of different types of computer-assisted phonemic segmentation training on phonemic segmentation, reading, and spelling of children with learning disabilities. Finds that phonemic segmentation training using visual support has no advantage over auditory training alone. Suggests that preschoolers and children with reading and…

Studies the effects of computer-generated lecture material by using two groups of students and their examination scores. The first group was presented with still computer graphics for four weeks, then returned to traditional materials for a second four weeks. The second group used traditional materials first, followed by the computer graphics.…

Discusses biological applications of virtual reality technology that are under development, including making extraordinary scientific images available for the teaching of science. Explores the technology and the development of three-dimensional images. (LZ)

Describes a study that investigated the effects of visual control (self-controlled versus system-controlled) and gender difference on learning with scientific multimedia instruction, observed how boys and girls differed in navigating and processing visual information in a hypermedia environment, and examined how visual control influenced learning.…

Describes "Glass-box Interpreter" a low-level program visualization tool called Bradman designed to provide a conceptual model of C program execution for novice programmers and makes visible aspects of the programming process normally hidden from the user. Presents an experiment that tests the efficacy of Bradman, and provides…

Describes three-dimensional computer aided design (CAD) models for every component in a representative mechanical system; the CAD models made it easy to generate 3-D animations that are ideal for teaching perceptual skills in multimedia computer-based technical training. Fifteen illustrations are provided. (AEF)

Examines the influence of a student's visual access to the instructor during Internet-based audiographics training. A course was taught through lecture and slides over the Internet to students at seven remote sites and the availability of instructor video was manipulated. Results showed that increasing the video capability of an Internet-based…

Two studies examined effects of computer-assisted (CA) teaching methods in introductory psychology classes. In Study 1, we provided students with lectures supplemented with either overhead transparencies or CA visuals. In Study 2, we compared students who used an optional Web site with students who did not. In both studies we held constant lecture…
