....required as input only the current state of the problem, that is, the completed structure and the assumptions made to that point. Inferences about the function of the student s work would guide the advice presented to the student. In contrast to other work in intelligent tutoring systems, e.g. [2,4,5], we do not require a model of the student, which simplifies the coach considerably. The domain of thermodynamic cycles is of interest for several reasons. First, it concerns designed artifacts of considerable complexity, which provides a forcing function to move us beyond toy problems. In point ....

....is automatically updated each time students interact with the systerm According to Sison and Shimura [5] machine learning or machine learning like techniques have so far been used in two areas of student modeling research. First, many systems, such as DEBUGGY [6] ACM [7] THEMIS [8] and ASSERT [9], have used methods inherited from the area of machine learning in order to induct a single, consistent student model from multiple observed student behaviors. Furthermore, machine learning or machine learning like techniques have also been utilized for the purpose of automatically extending or ....

....errors. Behavior recognition is more important when dealing with complex behavior (e.g. programs) than when the behavior is, say, a single number. Hence, DEBUGGY (Burton, 1982) and ACM (Langley and Ohlsson, 1984) which deal with numbers in subtraction, and THEMIS (Kono et al. 1994) and ASSERT (Baffes Mooney, 1996), which deal with labeled propositions, perform relatively trivial behavior recognition. The bulk of their work is in the induction of the student model from a set of noncomplex behavior. 3 Definition 3 Behavior characterization is the process of differentiating between the student behavior and ....
....Model Induction in ASSERT Unlike synthetic SM induction, transformational SM induction (PIXIE, SMS1, Hoppe s) has no direct counterpart in inductive ML, although theory revision comes close. For example, using the propositional theory reviser NEITHER (Baffes Mooney, 1993) ASSERT (Baffes Mooney, 1996) induces an SM from the ideal model and a student s answers to a set of multiple choice questions, and it is the SM, rather than the student behavior, that is examined for misconceptions. Table 5 shows the basic procedure of model induction in ASSERT. Like THEMIS, ASSERT deals with behavior in the ....
