The prototype cloris system: Describing, retrieving and discussing videodisc stills and sequences

摘要

Given the problem of the incorporation of videodisc technology into an Intelligent Computer-Assisted Instruction (ICAI) framework, this article presents an outline of the methodological basis for, and the architecture and operation of, a prototype Video-based ICAI (VICAI) system. The aim of the system is to allow the learner to control the learning environment by watching video material (stills and moving film), interrupting it, and entering into a discussion about the visual and conceptual aspects of the events in progress and the objects on view. The prototype is to be used for experimentation with learners to investigate the strategic and learner-modeling requirements of VICAI systems.
