Multiple multimodal mentors: Delivering computer-based instruction via specialized anthropomorphic advisors

Abstract

We describe the Smalltalk Gurus, components of the MoleHill intelligent tutoring system for Smalltalk programming. The Gurus offer help on plans for achieving goals in the Smalltalk environment, as well as remediation for students' incorrect and less-than-optimal plans. The Gurus' assistance is provided via the multimodal media of animation and voice-over audio. MoleHill employs multiple Gurus to deliver advice and instruction concerning disparate information domains, thus facilitating learners' cognitive organization and assimilation of new knowledge and information. We have labelled the approach instantiated by the Smalltalk Gurus the guru instructional model, one which is generally applicable to computer-based advisory systems. © 1995 Taylor & Francis Group, LLC.
