An Analogy-Based Computer Tutor for Remediating Physics Misconceptions. Draft.
Murray, Tom; And Others
This paper evaluates the strengths and limitations of a computer tutor designed to help students understand physics concepts. The tutor uses a teaching strategy called "bridging analogies" that previous research has demonstrated to be successful in one-to-one tutoring. The strategy is designed to remedy misconceptions by appealing to existing correct intuitions, and extending these intuitions by encouraging analogical thinking. Through a pretest (N=180) and a video-taped interview study, (N=25), subjects who answered the target for which a misconception existed incorrectly with high confidence and the analogous anchor correctly with high confidence were chosen to participate. Three types of data were collected: (1) notes taken by the interviewer during the sessions; (2) a computer trace of the tutor's actions and user responses; and (3) videotaped recordings of the sessions (which totaled 15 sessions, 3 of which involved student pairs). Results of this formative evaluation indicates that most of the subjects improved their understanding of Newton's third law. Suggestions for improving the computer tutor using artificial intelligence technology were discussed. Appendices include the program data structures and algorithm, and an example section of a trace file. (YP)
