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…

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.…

Outcomes of a project designed to develop the knowledge base necessary for creating an expert system that would help nonprofit organizations select fund-raising software are presented in this paper. When the system is completed, its components will ask the user for information that will assist in determining the organization's administrative needs…

Presents an engineering environment oriented to the development of hypermedia applications for training. Training trends are described; requirements for a computer-based training (CBT) strategy are outlined; a hypermedia course structure is examined; microinstructional events (MIEs) are explained; and technology requirements and selection are…

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…

Discusses whether machines can think in the same sense that humans think. Provides four conclusions based on axioms of differences between computer programs and human minds. Compares claims of strong and weak artificial intelligence. (YP)

Discussion of expert systems focuses on a national survey that gathered information concerning the attention and investment given to expert systems by managers and computer professionals in a variety of fields. Highlights include uses of expert systems, types of computers and software used, and expert systems shells and development costs. (18…

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.…

Discusses hypertext and describes three abstract models that represent different levels in the design-decision process necessary for effective hypertext development. The use of information management software is discussed; combining hypertext and information retrieval models is considered; and opportunities for hypertext are described, including…

Presents a study undertaken to determine what types of visuals are being used for presentations in different business organizations. Discusses findings in terms of: description of respondents; creating and using visual aids for presentations; presentation software used; using special software features; and presenting the visual aids.

High-performance computing refers to the use of advanced computing technologies to solve highly complex problems in the shortest possible time. The federal High Performance Computing and Communications Initiative of the Advanced Research Project Agency (ARPA) attempts to accelerate availability and use of high performance computers and networks.…

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…

Identifies key factors affecting conceptual gains from using a CAL (computer-assisted learning) package and their application to a college practical laboratory class. Considers students' biographical characteristics, design features of the CAL package, and the way that the CAL was integrated into the curriculum. (Author/LRW)
