Discussion of effective search aids for legal researchers on the World Wide Web focuses on the design and evaluation of two software systems developed to explore models for browsing and searching across a user-selected set of Web sites. Describes crawler-enhanced search engines, filters, distributed full-text searching, and natural language…

Reports on the design and implementation of PBS (Parsing, Boolean Recognition, Stemming), a software module used in conjunction with an intermediary program to interpret natural language queries used for online database searching. Results of a test of the initial version, which is designed for use with bibliographic files, are reported. (13…

Classifies types of electronic books: archival, informational, instructional, and interrogational; evaluates five commercially, available examples and two in-house examples; and describes software tools for creating and delivering electronic books. Identifies crucial design considerations: interactive end-user interfaces; use of hypermedia;…

Evaluates CorrecText, Houghton-Mifflin's computer-based grammar checker that fully parses sentences and finds errors in grammar, style, and usage. Argues that, while CorrecText is an improvement over similar programs, it still cannot accommodate the syntactically ambiguous nature of English. Limits current design's usefulness to unedited prose.…

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…

Identifies some of the common features of authoring programs. Outlines factors to consider when buying an authoring software package, including access to equipment, development and maintenance of courseware, purchasing and updating hardware and software, platform selection, and authoring skills. Presents a list of questions to ask vendors before…

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…

The MEDA (Methodologie d'Evaluation des Didacticiels pour les Adultes) tool is a generic instrument to evaluate training courseware. It was developed for software designers to improve products, for instructors to select appropriate courseware, and for distributors and consultants to match software to client needs. Describes software evaluation…

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…

Reviews problems with educational software and presents a framework for educational software design, focusing on topic selection, knowledge presentation (simplicity, presentation, program control, structure versus exploration, navigation), knowledge construction (multiple choice, tasks, case studies) and evaluation. (PEN)

Describes a methodology for estimating the time required to design, develop, and evaluate interactive courseware that was prepared for the Air Force. The original methodology is explained, based on degree of interactivity, use of media, instructional content, and presentation format; the evaluation study is described; and the revised methodology…

Describes an interactive computer program, COLOR-TEST, that was developed at the Technical University of Sofia (Bulgaria) to teach color harmony and color coordination to industrial design students. A brief evaluation of the program is presented, and further developments for the program are suggested. (nine references) (LRW)

Addresses the issue of assuring quality software for use in computer-aided instruction and presents a structure by which developers can create quality courseware. Differences between courseware and computer-aided instruction software are discussed, methods for testing software are described, and human factors issues as well as instructional design…

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…
