Discusses the development of computer-assisted music instruction at Ohio State University and describes a courseware development system for the Apple Macintosh microcomputer that facilitates the creation of sophisticated computer-assisted music instruction programs. Walter Hewlett's pitch representation system is described, structured programing…

Discusses the evolution of mainframe and personal computers, and presents a case study of a network developed at the University of Iowa called the Iowa Computer-Aided Engineering Network (ICAEN) that combines Macintosh personal computers with Apollo workstations. Functional objectives are stressed as the best measure of system performance. (LRW)

An approach to the design of flexible text-based management systems for archives includes tiers for repository, software, and user management systems. Each tier has four layers--objective, program, result, and interface. Traps awaiting software development companies involve the market, competition, operations, and finance. (10 references) (MES)

Discussion of electronic performance support systems (EPSS) focuses on performance support engineering and its role in designing performance support systems. Highlights include the organizational performance/learning cycle model; a systems approach to EPSS; computer-based training and other EPSS methodologies; and future possibilities. (LRW)

Gives practical tips on how to retrieve and view images from Internet databases, with a description of image file formats and the requirements for viewing and decompression software. A list of nine image databases and a brief description of the University of Arizona library's digital image project are provided. (Contains four references.) (KRN)

Discusses multimedia design and the shift in models from computer-assisted instruction and audiovisual learning to multimedia environments and computer-based learning environments. Topics addressed include multimedia generations and architectures; changing trends in software development; object-oriented design; and the design of media systems.…

Describes a study that examined the effectiveness of implied boolean searches using personal author surnames plus first and/or last title words to retrieve an entry from a simulated online public access catalog (OPAC). Implications for the design of OPACs are discussed, and further research is suggested. (LRW)

Describes "DesignStation 2000," a software and hardware workbench for laptop computers for the design of learning systems that includes capabilities for needs analysis; client presentation and proposal generation; rapid prototyping of interactive media projects; collaboration and project tracking; assessment of results; and adding to a…

Examines the relationship between computer-user interface (character-based or graphical) and the quality of documents written by college students. Finds that, after six weeks of business communication instruction, IBM users excelled on the criteria of mechanics and format, but that after five more weeks the two groups demonstrated no significant…

Discusses the development of phraseological machine translation based on the theory that in natural languages, phraseological units cannot always be reduced to words. Describes the phraseological translation process of computer software and machine dictionary systems that translate Russian into English and English into Russian. (JMV)

Discusses movie on demand (MOD) servers, which are computer systems that store movies in compressed digital form for broadcast cable television systems. Highlights include network bandwidths, a disk-based storage architecture for a MOD server, implementing VCR (video cassette recorder) functions to movie viewing, and buffers. (LRW)

Discusses the design of management information systems for secondary schools and presents a fundamental approach to systems design that was used for the development of SCHOLIS, a computer-assisted school information system for Dutch secondary schools. The importance of information system development methodologies is stressed. (LRW)

Discusses the need for online help for end-users based on experiences with an online public access catalog (OPAC) at the University of Cape Town libraries. The concept of end users is examined, the role of search intermediaries in information systems is explained, and online help and systems design is discussed. (LRW)

Provides an overview of Circuit II, an interactive system that provides users with a graphical representation of an electronic circuit within which questions may be posed and manipulated, and discusses how mouse selections have analogous roles to certain natural language features, such as anaphora, deixis, and ellipsis. (13 references) (EA)

Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…
