Describes applications of HyperCard, including SuperDuper Gradebook and HyperMedia Information Retrieval System (HIRS). Also described is the creation of an instructional software library called the HyperMedia and Instructional StackWare Clearinghouse (HISC), which will evaluate programs for educators, trainers, and instructional technologists.…

Presents a BASIC program that can be useful in explaining physicochemical phenomena underlying the generation of membrane potential in excitable cells. Its simplicity allows students to understand the nature of these processes through a direct, hands-on approach. Also, the simulated voltage and concentration kinetics agree well with those…

Describes how a software program for DOS/Windows manages a collection of pictures such as photographic slides, overheads, or computer images in one or more databases. Explains how it transforms image files to raw binary files that can then be displayed like flash cards, or as an animated series of images. (Author/LRW)

Discusses changes in accepted approaches to teaching and learning, shifts in psychological and pedagogical theory towards a constructivist view of learning, and the consequences of these theoretical shifts for computer assisted learning. Explains a classification scheme for constructivism that provides a framework for looking at constructivist…

Discusses equity in access to Internet technology. Highlights include equity at school; the Internet factor, including the e-rate; access in the community, including computer camps; home access to the Internet; and the importance of technological literacy, for education or for work. (LRW)

Lists 21 Web sites that are helpful for school librarians. Includes general search engines and how they determine hits; specialized search engines on specific topics; and other topical sites. (LRW)

Describes videoconferencing using Sorensen EnVision, a hardware-accelerated desktop videoconferencing solution that allows low bandwidth communication using the Internet. Presents example of its use for conducting meetings and in a variety of educational settings. (LRW)

Discusses educational technology in general and then considers the drawbacks and possibilities of educational computer technologies as a subset. Suggests that the proper use of the computers needs to be addressed more than the mere fact of having computers. (LRW)

Discusses multimedia and its use in classroom teaching. Describes integrated services digital networks (ISDN); video-on-demand, that uses streaming technology via the Internet; and computer-assisted instruction. (Contains 19 references.) (LRW)

Examines instructional computer simulation from a Heideggerian point of view, claiming that traditional conceptions of simulation do not account for important characteristics of existence, namely anxiety and waiting. Discusses Heidegger's conception of Bestand, or standing reserve, and suggests implications for instruction. (Author/LRW)

Shows how counterfactuals and machine learning methods can be used to guide exploration of large databases that addresses some of the fundamental problems that organizations face in learning from data. Discusses data mining, particularly in the financial arena; generating useful knowledge from data; and the evaluation of counterfactuals. (LRW)

Emphasizes the importance of systematic and full-fledged R&D (research and development) in educational computing. Describes high technology R&D frameworks outside of education in business and industry, and discusses increasing the effectiveness and quality of educational computing R&D. (LRW)

Describes CASTE (Course Assembly System and Tutorial Environment) that was developed to help students choose appropriate learning strategies in a hypertext environment. Highlights include the need for principles of course design; resource-based learning and computer-aided learning; conversation theory; and a comparison to other approaches.…

Children tend to view the equals sign as an operator symbol bereft of the rich relational properties of equality statements. It has been argued by some that this restricted view of the equals sign is due to cultural or cognitive factors. We suggest a significant factor is that rich relational meanings lack relevance within the context of…

One of the psychological states that can be monitored and influenced during learning in order to improve its various aspects is the state of anxiety, and one possible index of this state is frontal EEG beta. However, frontal EEG beta has also been associated with mental activities. This may imply that frontal EEG beta would not be a reliable index…
