Describes videotex development; discusses optimal internal organization, visual display, and presentation of information on videotex screen; addresses policy issues of equity, privacy, and costs that affect instructional use of videotex; outlines videotex field trials and experiments within education; and draws conclusions on significance of…

Describes the style of design of computer simulations developed by Computer Assisted Teaching Unit at Queen Mary College with reference to user interface, input and initialization, input data vetting, effective display screen use, graphical results presentation, and need for hard copy. Procedures and problems relating to academic involvement are…

Self-regulated learning with authentic and complex problems requires that learners observe their own learning and use additional information when appropriate (e.g., hypertextual information in computer-supported learning environments). Research indicates that learners in problem-based environments often have difficulties using additional…

Encourages using spreadsheets to teach college economics because of their capacity to depict economic models, strengthen logical ability, and manipulate large amounts of data. Lists spreadsheet packages that are available and offers detailed instruction through graphs on how to design and interpret spreadsheets for classroom use. (CH)

Describes study that was carried out at the University of Calgary to determine how elementary school children conceive of computer-related tasks and how this information might be used to generate animated icons for educational software. Child-computer interaction is discussed, and differences in responses between three age groups are examined. (10…

When students feel that their learning needs are not being met by computer-aided instruction, learning becomes passive, often resulting in boredom, frustration or a dislike for learning with computers. "Button Theory" allows the student to express his feelings and questions to the computer at the touch of a button, thus enhancing control over the…

This paper argues that recent developments in technology hold considerable promise for distance education. Audiocassettes, audiographics (the combining of natural sound, via the telephone or audiocassettes, with computer-generated graphics), videocassettes, and computer conferencing are used as examples to identify factors that should be…

The development and evaluation of a potential viewdata-style delivery system for computer assisted learning (CAL) at the Open University are described. First examined are Open University problems with CAL and television delivery systems, which resulted in the consideration of a viewdata approach involving allocation of a small central processor to…

Hardware for computer-assisted learning is discussed in three papers. Two papers report on projects using computer graphics, one for teaching structural analysis to university students and the other to teach graph concepts at the secondary level. Guidelines for selecting microcomputers focus on analyzing applications and matching them with…

Describes the Book House, an interactive, multimedia online public access catalog (OPAC) developed in Denmark that uses icons, text, and animation. An alternative design model that addresses problems in OPACs is described; and database design, system navigation, use for fiction retrieval, and evaluation are discussed. (20 references) (MES)

Describes microcomputer-based courseware designed for the simulation of the microbiological analysis of drinking water, including digitalized color images. The use of HyperCard is described and evaluation procedures are explained, including evaluation of the learning and of the class. The evaluation questionnaires are appended. (20 references)…

Outlines the implementation, production, and assessment of electronic posters in two undergraduate classes, one prepared with Microsoft PowerPoint and the other using hypertext mark-up language (HTML). Describes the advantages of each, along with the grading schemes and comments about implementation. Concludes that the exercises are useful for…

The IRT (Item Response Theory) has been studied and applied in computer-based test for decades. However, almost of all these existing studies evaluated focus merely on test questions with text-based (or static text/graphic) type of presentation form illustrated exclusively. In this paper, we present our study on test questions using both…

The use of computer technology in history instruction permits students to explore the data, and formulate and test their own hypotheses within the confines of the data, rather than being passive receptors of someone else's interpretations. The Gallipoli project brought together materials from a national war archive to develop a multimedia teaching…

Most use of multimedia technology in teaching and learning to date has emphasized the teaching aspect only. An application of multimedia in examinations has been neglected. This paper addresses how multimedia technology can be applied to the automatization of assessment, by proposing a prototype of a multimedia question bank, which is able to…
