Discusses a three-year research project in which a virtual environment to teach radioactivity in secondary schools in the United Kingdom was developed and tested. Emphasizes the importance of involving teachers through the development process and confirms the importance of school-based evaluation studies in the development and evaluation of…

Describes "Focus," a software tool for collecting reader comments more efficiently. Discusses the design and rationale of the software. Notes that results obtained using Focus were compared to the reader feedback collected under the plus-minus method. Concludes that Focus participants appeared to comment more from a reviewer's and less…

Discusses results of a survey of 15 educational software developers, which indicate that none of the companies perform any empirical evaluation of their products as part of the development process. Importance and advantages of validation of the effectiveness of a program are considered, and suggestions for encouraging such validation are offered.…

Argues that traditional methods of testing software products leave too little time for major modifications and that in-cycle usability testing is required. Reports a study of environmental factors that constrain such testing. Concludes that it is not yet routine because of budget and staff limitations, lack of performance standards, and untrained…

Examined the use of the TREC Information Retrieval Test Collection for evaluating visual information retrieval interfaces (VIRI). Found that TREC data sets were suitable as development tools for VIRIs and traditional information retrieval systems and that the computational cost of organizing data into useful visual fields were high and related to…

This paper looks at bugs and errors in the following commonly used statistical packages: SAS, Statistical Package for the Social Sciences (SPSS), Biomedical Data Plan (BMDP), and Minitab. A section on using the Internet to keep up to date on these packages covers subscribing to statistical software lists, searching statistical software lists,…

Presents specifications for software that is designed to support manual development and maintenance of information retrieval thesauri. Evaluation of existing software and design of custom software is discussed, requirements for integration with larger systems and for the user interface are described, and relationships among terms are discussed.…

Reviews selected strategies employed in educational and training psychology that might be incorporated into library and information management software. Based on this review, a number of potentially useful features are identified, and an exploratory study of a sampling of library and information management software is conducted based on these…

Describes a microcomputer-based digital video course that uses virtual reality to teach the code inspection (i.e., formal software technical review) process. Use of virtual reality for group process activities that involve interpersonal and group dynamic skills is discussed, and research indicating that realism improves course effectiveness is…

This paper describes the creation and evaluation of a World Wide Web-based courseware module, using conceptual models based on constructivism, that teaches novices how to use the Internet for searching. Questionnaires and interviews were used to understand the difficulties of a group of novices. The conceptual model of the experts for the task was…

Discusses use of Vygotsky's zone of proximal development as a theoretical construct for designing Ecolab educational software. Describes an evaluation of the software with elementary school students, noting the usefulness of the ZPD construct despite students' inability to set up challenging tasks and seek appropriate assistance. Considers issues…

Describes a study conducted in Finland that investigated designers' and teachers' conceptions of learning and evaluation criteria for educational software. Results indicate that designers emphasized the appearance of software while teachers referred more to practical teaching arrangements, and that participative and collaborative design is needed.…

Describes an empirical study of students in a Swiss secondary school that was conducted to investigate whether courseware and student characteristics have an impact on learning achievement. Factors to be considered in the design and evaluation of courseware are discussed, students' computer attitudes are considered, and recommendations for further…

In this paper, an attempt to apply the synthesized results from previous research on theories of actual development of courseware is demonstrated in an interactive videodisc project that aims to promote English-as-a-foreign-language learning at Tsing Hua University in Taiwan. Instructional design and practical considerations for implementation of…

Hypermedia technology offers new opportunities for developing earth science teaching materials. During the past 3 years, the U.S. Geological Survey has conducted a series of research and development projects to assess the effectiveness of hypermedia technology in providing innovative teaching products for middle school students. The goal of this…
