Discusses computer assisted instruction programs that deal with the specific area of the modeling of systems and the programing techniques that affect their educational value. An environment intended to increase the impact of interactive CAI is described and developed. (Author/CHC)

Describes a study that investigated the performance of preschoolers and children in the first three years of formal education on tasks that involved skills using a mouse-based control of a graphical computer interface. The children's performance is compared with that of novice adult users and expert users. (five references) (LRW)

Discusses the design and development of the user-computer interface in terms of the personal computer user's psychological needs and physical, perceptual, and conceptual contact with the system. Principles for the development of a user-system dialog that meets the requirements of transparency and visibility are suggested. Twenty-six references are…

The MUMEDALA (MUlti-Media Authoring LAnguage) system is an authoring facility that is designed to enable the creation and control of a sophisticated interactive learning environment. This paper presents an overview of the system, its design features, and progress being made towards its realization. Twenty-three references are included. (Author/MBR)

Discussion of research on computer-aided instruction (CAI) focuses on a set of questions and hypotheses that form the basis for research on the effectiveness of CAI. Four factors are highlighted: (1) the medium (including interactive videodisc); (2) the environment; (3) student characteristics; and (4) topic of instruction. (38 references) (LRW)

Reports the development of a classification system for microcomputer-based software according to the depth and type of involvement of the user with the software. Three studies are discussed that used the facet approach, multivariate statistical procedures, and questionnaires to investigate types of involvement produced by computer programs. (18…

Six papers on future developments in computer-assisted learning (CAL) focus on the impact of computers on the future of education, use of path algebras for network analysis, impact of "programing literacy" on courseware, microcomputers as classroom teaching aids, Prestel for preschool education in the home, and courseware development and…

This paper presents ongoing research at the University of Hertfordshire on the use of computer-adaptive tests (CATs) in Higher Education. A software prototype based on Item Response Theory has been developed and is described here. This application was designed to estimate the level of proficiency in English for those students whose first language…

Describes the development and evaluation of an interactive videodisc designed for Open University students in a physics course that explores the physical properties of water. The user interface is discussed; software is described; videodisc production is explained; and results of an evaluation of student attitudes from questionnaire responses is…

Reviews research and development projects sponsored by the National Aeronautics and Space Administration (NASA) that address microcomputer-based support for instructional activities at the University of Southwestern Louisiana. Highlights include a graphics project, local area networks, and the Interactive Presentation Development System, which is…
