Previous work applying cognitive load theory has demonstrated the effect of various text/graphic/narration relations on learning using multimedia material. Other work has looked at how the degree of integration between the text and graphics influences their use. This study set out to look at how the degree of integration between text and graphics…

Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…

Critiques existing approaches to computerized support for browsing and describes four new types of browsers that have been implemented in the Xerox NoteCards hypertext system. These browsers support the process of pursuing and returning from digressions and facilitate the integration of diverse sets of materials that have been browsed. (16…

PowerPoint is widely used for a variety of purposes in today's university and public school classrooms. Many children in the elementary grades quickly learn to prepare PowerPoint presentations with ease. Sometimes, however, we believe that PowerPoint presentations are overused and ineffective, especially when one is subjected to viewing several of…

Boundary extension is a tendency to remember close-up scenes as if they extended beyond the occluding boundaries. The authors explored the contributing factors using brief retention intervals and computer-generated images. Boundary extension turns out to be more complex than previously thought and is not linked to the effects of image…

A computer program written for the Apple II was designed to teach college students how to map expository information. The program consists of five lessons, the first beginning with a definition and illustration of mapping. In this introductory lesson, students are asked to answer three basic questions when reading expository text: identify the…

Critical reasoning has been recognized as a valuable educational goal since the end of the nineteenth century. However, the educational programs to reach this goal have changed dramatically during the twentieth century and moved to a dialogic approach. The shift to dialogism in programs to promote critical reasoning brings challenges concerning…

In most existing computer assisted instruction (CAI), the nature of the instruction would not actually require a computer. Text is presented and read, questions are asked, and then materials are presented or reviewed depending on students' answers. There are two problems with this approach: computer capabilities for interactive task simulation are…

Three developments over the past 15 years--our understanding of cognition, new techniques in technical psychometrics, and the computer explosion--form the basis for a proposal for new intelligence tests. These developments are reviewed, and both leaps and steps in intellectual assessment are proposed. (Author/RD)

Discusses how to develop effective instructional graphics for multimedia instruction. Topics include graphic symbols; how graphic symbols are processed cognitively; how multimedia graphics affect learners; how graphics can be adapted to educational products for a variety of populations, including adults and children; and a checklist for creating…

Presents rationale for including use of productivity tool software--database management systems, spreadsheets, graphics software, word processing--in classrooms and reviews appropriate strategies for introducing students to these tools. Discussion covers adaptability of these tools to various academic disciplines and illustrates how students…

Explains federal standards that libraries can use to make Web sites accessible to users with disabilities. Describes Section 508 standards from the Rehabilitation Act of 1973; types of disabilities to consider, including vision, hearing, mobility, cognitive impairments, and seizure disorders; graphics; and conflicting interpretations of the law.…

Examines mathematics problem solving in a computer software environment using graphical representations of the results of simulations with adolescent students. Discusses the strengths and limitations of inferring goals and plans, the use of verbal protocols, and ways for computer-based learning environments to scaffold acquisition of domain…

Computer Supported Intentional Learning Environments (CSILE) is a project using computer software to promote the constructive processes involved in intentional learning. CSILE enables groups of students to build a collective database (knowledge base) of their thoughts, in the form of pictures (created by students using a color graphics editor) and…

This paper examines hypermedia design and draws conclusions about how educational research and theory applies to various aspects of World Wide Web (WWW) homepage design. "Hypermedia" is defined as any collection of information which may be textual, graphical, visual, or auditory in nature and which may be accessed via a nonlinear route.…
