ABSTRACT
The main efforts have been concentrated upon the adaptation of a Danish version of a knowledge-based system shell (DLH-MITSI), for use in schools (seventh through eleventh grade). The adaptation builds on a system developed in the United Kingdom by Jonathan Briggs, called MITSI (Man In The Street Interface), which is an introduction to essential features of logic programming (the system is written in LPA Prolog Professional), as well as a system shell for building knowledge based systems ("expert systems"). Work in the schools will concentrate upon one aspect of the system: a tool for analysing knowledge. The main assumption is that it is pedagogically and psychologically important to have a tool available, by which the issued of knowledge construction, knowledge representation and knowledge acquisition and use may be made "concrete". Analysis of a selected domain may be undertaken by pupils, and teachers and pupils, cast in the shape of constructing a DLHMITSI-programme. Such a programme consists of an information base, coupled with one or more rule-bases drawing on the inference-engine built-in in the underlying Prolog, on the basis of a conceptual analysis of the domain.
