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…

Discusses the need to expand spatial analysis based on Geographic Information Systems (GIS) and display methods to encompass group decision-making processes. Descriptions of enhancements and additions to software that will enable GIS technology to be used by groups are included. Issues highlighted include implementation and design. (54 references)…

Reviews the historical evolution of computer-assisted instruction (CAI) and discusses recent advances in intelligent systems. Intelligent tutoring systems are described from the system designer's and learner's perspectives, and possible future applications are considered. A list of existing intelligent CAI systems is provided. (14 references) (CLB)

Discusses intelligent tutoring systems (ITS), one application of artificial intelligence to computers used in education. Basic designs of ITSs are described; examples are given including PROUST, GREATERP, and the use of simulation with ITSs; protocol analysis is discussed; and 38 prototype ITSs are listed. (LRW)

Provides an overview of expert systems for teacher librarians. Highlights include artificial intelligence and expert systems; the development of the MYCIN medical expert system; rule-based expert systems; the use of expert system shells to develop a specific system; and how to select an appropriate application for an expert system.
