McCarthy, John C.; And Others – Human-Computer Interaction, 1993
Analyzes requirements for text-based online conferencing through the use of a minimal prototype. Topics discussed include prototyping with a minimal system; text-based communication; the system as a message passer versus the system as a shared data structure; and three exercises that showed how users worked with the prototype. (Contains 61…

Kilgour, Frederick G. – Journal of the American Society for Information Science, 1995
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)

Bhola, H. S. – 1991
The point is made that systems thinking should be combined with dialectical thinking and constructivist thinking for effective systems design and systems change. To establish a context, a set of assertions on "How the World Works" in regard to systems design and systems change in education is laid out, as value assumptions undergirding…

Wehrs, William E. – Journal of Research on Computing in Education, 1992
Computer-assisted advising can be an effective support for conventional academic advising. A shell-based expert system allows computer-assisted advising without automated student records, because students maintain and input their own records into the system. The Expert System for Advising Undergraduates (ESAU) used in the management department of…
