Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

A recent survey of 60 commercial computer assisted instruction (CAI) programs found that most of the programmed lessons used few or no graphics to communicate the main points. An Instructional Graphics Checklist was developed to reflect the research findings about the use of pictures in instruction and to serve as an informal evaluation instrument…

Guidelines for designing effective multimedia presentations are presented. The differences between computer-based and computer-aided presentations are highlighted. Advice is given for the effective selection and use of layout, color, sound, and graphics. Room layout, lighting, equipment, and backup are examined and recommendations are made.…

This paper explores the role of computerized simulations as a decision-modeling intervention strategy, and views the strategy's different attribute biases based upon the varying primary missions of instruction versus application. The common goals associated with computer simulations as a training technique are discussed and compared with goals of…

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…

This study was conducted to field-test collection mapping as an evaluation technique, to determine collection standards against which individual schools could compare themselves, and to compare the collections in schools to nationally-recommended lists published by Brodart and Wilson. Questionnaires were sent to 120 library media specialists in…

Teachers College of Columbia University (New York) and the Dalton School, an independent school in New York City, have collaborated on the Dalton Technology Project and its "Archaeotype" program which presents students with a graphic simulation of an archeological site. Students simulate digging up the artifacts, use reference sources to…
