Abstract

Distance education, delivering high quality, individualized instruction in inexpensive, expandable, and accessible ways is a major challenge for today's universities. This paper presents the most recent work in the field of fault tolerant teaching (FTT). Fault tolerant teaching systems will augment computer-based learning materials with the tools to assess and correct student knowledge. FTT methods automatically create a concept model of an instructional topic, based solely on student responses to tutorial questions, using a statistical method related to data mining. This concept model can be used to assess student knowledge as he progresses through a tutorial, while tolerating the usual errors that occur during testing - such as a student guessing answers or mistyping a response. This paper presents the ongoing results of an experiment designed to test the validity and accuracy of FTT-based assessment methods.
