What is Wrong with this Equation? Error Detection and Feedback with Physics Equations

Oneof the keys to a goodIntelligent Tutoring System (ITS)is its ability to identify andlocalize the error a student's answerand then generate useful feedback. This paper describes an algorithm that wehave developed for analyzing errors in algebraic equations and generatingfeedbackthat is specific to the context. We have implementedthis algorithm and identified some of the knowledgethat is useful for this domain. Our experimentsindicate that manyerrors can be handled with a limited amountof domainknowledge.
