This paper describes the notion of two-way communication, wherein the receiver can question or challenge the transmitter of the information, and shows how it differs from the one-way forms of communication that are more prevalent in developed countries today. Pointing out that today's broadcast and mass-market print media usually take the form of…

Discussion of problems students have with learning about Newtonian dynamics and kinematics focuses on the assumption that learning is promoted through confronting students with their own misconceptions. A computer-based modelling environment--DYNLAB--is explained, and a study conducted with high school boys in Scotland to test it is described. (29…

This discussion of the benefits of audio teleconferencing for distance education programs and for business and government applications focuses on the recent experience of Canadian educational users. Four successful operating models and their costs are reviewed, and it is concluded that audio teleconferencing is cost efficient and educationally…

Presents a description of PLEXUS, an expert system on gardening designed as a referral tool for public libraries by the University of London. Highlights include determining user characteristics, developing the problem statement, the use of semantic categories, and search strategies that modify the original problem statement using Boolean…

This paper discusses two conflicting opinions on the role of computer education within the West German school curriculum, i.e., the opinion of the majority of the education ministers and administrators, who wish to see computer use distributed over as many school subjects as possible, and a minority of specialists in computer education who prefer…

Describes a survey of 724 management students in New Zealand's Technical Correspondence Institute which was conducted to determine whether the introduction of educational technologies could decrease the dropout rate. The multiple linear regression model that was used to analyze the questionnaire responses is presented, and predictor variables are…

Presents an overview of a course on robotics and automation developed by the Organization for Rehabilitation through Training (ORT) to be offered through an open learning environment in the United Kingdom. Highlights include hardware and software requirements, an educational model, design principles, and future developments. (LRW)

Describes design principles followed in developing an interactive microcomputer-based simulation to study financial and economic aspects of the Dutch social security system. The main goals are to improve participants' insights into the formal simulation model, and to improve policy development skills. Plans for future research are also discussed.…

The interactions between computer use and access by adolescents and their computer-related opinions and values are presented in the framework of a "manifold model" of computer interactions. This model emphasizes the complexity and multidimensional nature of the system of variables in which such interaction is embedded. For this study,…

This paper, on the returns on investment (ROI) in training, introduces some practical examples for enterprises or organizations wanting to find out whether the money they have spent or intend to spend on training is necessary. It provides strategies for researchers who would like to undertake research in this area. The paper begins by examining…

This paper describes the Manifold Access Model, which has been developed for the simultaneous representation and analysis of the interrelationships between five variable clusters: (1) computer access; (2) personal and social attitudes and values with respect to computer use; (3) self-assessed competence and confidence with respect to computer use;…

This comparison of students' learning from reading books and from watching television uses Gavriel Salomon's model of learning effects, which is based on the amount of mental effort invested (AIME) in a medium as determining how deeply the information from that medium is processed. Mental effort, in turn, is predicted to depend on two perceptions…

This book, aimed at mathematics and vocational educators and researchers, analyzes the historical, sociological, and practical elements of mathematics within vocational education against the emerging impact of technology. Focus is on the current situation of mathematics within Australian vocational and technical education and how that might be…
