Development of Angular Motion, Angular Momentum, and Torque Knowledge Bases for an Intelligent Physics Tutoring System

摘要

This research involved the design and development of a physics knowledge base which allows an intelligent tutoring system ANDES to more effectively assist students in physics problem-solving. The system tutors Newtonian physics via coached problem-solving a method of teaching cognitive skills where the tutor and the student work together to solve problems. The knowledge base developed in this project provides the physics backbone for the rest of the tutoring system by generating the necessary equations and solution graphs to solve selected angular motion physics problems. These mathematical outputs are used by other ANDES components to provide help to the students in a variety of ways. Since this research was the first attempt to develop a knowledge base for the angular motion area of physics encoding, these concepts presented unique challenges.
