Describes the design of an electronic performance support system (PSS) that was developed to help sales and support personnel access relevant information needed for good job performance. Highlights include expert systems, databases, interactive video discs, formatting information online, information retrieval techniques, HyperCard, computer-based…

This article reports on the design, development and evaluation of an educational virtual environment for biology teaching. In particular it proposes a highly interactive three-dimensional synthetic environment involving certain learning tasks for the support of teaching plant cell biology and the process of photosynthesis. The environment has been…

Background: Many of the agent-based products available to education today have been largely confined to games and instructional media that are often produced commercially by non-instructional professionals. Most of them lack customizability and are difficult to integrate into individual subject curriculum. With more agent authoring tools available…

Two groups of twelve dyslexic children and twelve good readers attended a two-week class during the summer following their enrollment in grades 4-6. The topic was the marine environment and focused on the adventures of an orca whale that had lost its family and needed the children's help. The children attended class for three hours each day, 45…

This study of student groups working with the Chelsea Bank computer simulation concentrates on the extent to which students are involved in activities related to the Secretary's Commission on Achieving Necessary Skills (SCANS) categories and to knowledge about work place practices. Studying students using the Chelsea Bank simulations offers the…

This project originated with the desire to offer general biology students a laboratory experience which emphasizes scientific thinking rather than a review of lecture content. To create investigative laboratories without many of the practical problems of their implementation, this project uses a combination of "methods modules" for…

Relying on estimates of variance explained to assess the practical significance of research findings is now common practice. It is suggested that such estimates can offer an inaccurate picture, often underestimating the practical significance of statistically small effects. As an example, research on employment discrimination indicates that in…

This publication contains a selection of science education research papers, beginning with an overview of trends in science education cognitive developmental research and theory in the United Kingdom. Papers that follow focus on developments in studies of thinking and reasoning, including work on concept mapping and conceptual change. Closely…

The papers presented at the 1989 National Educational Computing Conference focused on ways of using technology to improve educational quality. Topics of the 50 papers and more than 120 abstracts provided in these proceedings include applications of artificial intelligence and the development of expert systems; authoring systems; using the computer…

Density is the first intensive physical quantity students encounter that can be understood in terms of an underlying model, the particulate theory of matter. Learning about density provides students with explanations for a range of phenomena such as sinking and floating, and changes of state. Teachers report, however, that density is a difficult…

This paper reports on the design of an on-line simulation that enhanced preservice teacher practicum experience in the important area of literacy teaching. Research with more than 200 users of the simulation showed that it developed pre-service teacher understanding of complex classroom situations associated with the teaching of literacy by giving…

This case study describes how one autistic learner, an 11-year-old boy, became a co-researcher with university literacy instructors to investigate how hypermedia can help him develop language and literacy skills. Data was collected for one year from video taping, journal notes, interviews with teachers and parents, test scores, and student…

Examines the literature on the effectiveness of computers in social studies instruction and learning. Topics include drill and practice, tutorials, study guides, games and simulations, inquiry and problem solving, graphics, and word processing and writing. Contains 58 references. (LRW)

Describes a study that defined the principal techniques preservice teachers applied when completing specific microcomputer simulations. Analysis of simulation performance scores yielded three performance factors addressing techniques that defined teachers' misbehavior intervention, instructional delivery, and activity sequencing. Regression…

This paper describes two empirical studies which investigated the importance for spatial learning of view control and object manipulation within 3D environments. A 3D virtual chemistry laboratory was used as the research instrument. Subjects, who were university undergraduate students (34 in the first study and 80 in the second study), undertook…
