Describes activities using sensors connected to a computer via a data-logger. Elementary students investigated several scientific questions of sound, light, and temperature sensors including: What is the effect of putting a coat on a snowman? How can you make a hot drink cool down quickly? Do sound, light, and temperature vary in different…

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

This paper promotes further discussion and analysis of interactivity in learning environments and contains a classification of interaction types appropriate for consideration in multimedia settings. Through an examination of related factors associated with navigation and control, a matrix of interactive dimensions is proposed. (Author)

Describes functionality and user interface issues associated with the design of an automated system that provides a visually based online index to multimedia information for higher education. Topics include online lectures; bibliographic access; and the need for a hypermedia system that presents an integrated view of the materials with graceful…

A portal is the digital infrastructure for an online campus. Community portals, online service portals, and enterprise-wide platforms represent the three basic portal variations available for online campuses. They are differentiated by the offices represented, the campus audience served, and benefits provided to the school as a whole. (PGS)

This study of undergraduates investigates how cognitive style, online database experience, and task type influence users' search behavior on the Web. Considers time spent, the number of nodes visited, search performance, navigational style, and ways to improve Web interfaces and Web user training programs. (Author/LRW)

Investigated the role that interactive multimedia might play in scaffolding teacher-led classroom activities to help children construct more appropriate external representations for particular tasks and reason more effectively about historical chronological concepts. Reports on the conceptual design and pedagogical approach to developing effective…

This paper reports a test on the feasibility and educational value of probeware and associated instructional materials in middle school science education. We addressed feasibility through consideration of costs, teacher professional development, and instructional design. In order to test our approach, we developed 2 middle school science…

As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…

In recent years laptop computers have become increasingly popular in educational settings; wireless connectivity is a more recent development which is only now being fully explored, and which has led to the creation of the "wireless laptop lab." In this article, the authors share some of the experiences and concerns that they have encountered…

This paper reports a synchronous project, "the virtual classroom" prepared for the Distance English Language Teacher Training (DELTT) Program. The process of developing the synchronous project and the interface with its specific components were reported with examples and supported by theoretical background from the related literature.…

Graphs of objects in motion are frequently used in introductory high school or college physics courses since they offer a valuable alternative to verbal and algebraic descriptions by offering students another way of manipulating the developing concepts. If graphs are to be a valuable tool for students, then the level of the students' graphing…

Multimedia is developing fast due to the convergence of different media (text, data. graphics, video, audio) into a common digital platform, and due to the convergence of telecommunications, television, and computing. Parallel to these technical convergencies is another set of developments in work and leisure that is opening up new markets for…

The two papers presented in this document discuss aspects of the computer revolution and its effects on the production of print materials. The papers are addressed to readers who are educators rather than technologists. The first article, entitled "Print," interprets that term broadly to include text development and production, and…

Computer-based instruction (CBI) has undergone tremendous changes in the past decade. This paper focuses on the following three areas of designing information presentation: (1) screen design literature is dated, and the existing guidelines do not allow for advances in computer technology; (2) open-ended guidelines may offer designers sufficient…
