Instructor's Plan: A Lesson Planning Expert System for School Teachers.
Wilkins, Dennis A.; And Others
The product of several years of research and development at Brigham Young University, Instructor's Plan (IP) is an expert system for rapid lesson design and authoring. Its primary audience is preservice and inservice school teachers. It will run on IBM PC, XT, AT, and PS/2 systems and compatibles with a color monitor and at least one floppy disk drive. IP's central feature is its expert system, which possesses two primary components: a knowledge base and an inference engine. Founded on instructional theory that proposes that specific learning conditions require different instructional strategies or strategy modifications in order to optimize learning, the knowledge base contains both production rules and instructional strategies. The instructor can access directly and make modifications to the instructional strategy aspect. The inference engine manages the knowledge base and the inferencing process, governing the questions posed to the instructor and the searching of rules, and testing the goals of the expert system to see if they have been accomplished. IP considers two main categories of learning conditions when determining the best instructional strategy--learning outcome and instructional mode--and identifies eight learning outcomes: response, recitation, explanation, classification, prediction, decision, performance, and problem solving. The instructional mode refers to whether the lesson is more instructor or learner centered and controlled. Formative evaluation has shown that instructors find IP very easy to learn to use and they report that it reduces planning time and improves the quality of their lesson design. (11 references) (BBM)
