TPIXIE: A Computer Program to Teach Diagnosis of Algebra Errors

Abstract

This research note examines the implementation of the program used in this study, TPIXIE, which was predicated on the assumption that acquiring the skill to diagnose student errors is important to trainee teachers. The TPIXIE system, a part of the PIXIE family of intelligent tutoring systems, was designed to present users with a series of task-student-answer pairs (where the student's answer was incorrect). The system presents several sets of tasks together with a student's responses, and then presents further tasks, while asking the user to predict the responses. If the user is unable to do this, the complete student working is displayed, and the cycle is repeated. Keywords: Artificial intelligence, Expert systems.
