CONSTRUCTION AND VALIDATION OF A COMPUTER-BASED DIAGNOSTIC MODULE ON AVERAGE VELOCITY

This article describes the process of building a computer-based diagno stic module concerning the understanding of the average velocity conce pt. The first step consists of the production of a student model that takes into account student errors and reasoning paths. The computer mo dule formulates its diagnosis by leading users along different pattern s foreseen according to the hypothesized student model. Results are re ported concerning a correlation analysis between automatic and human d iagnoses.
