| Abstract: | The problem of diagnosing performance errors has been of interest to both educationalists and artificial intelligence researchers for many years. Multicolumn subtraction has been a popular domain in which to experiment with the diagnosis of errors (Burton, 1982). Ohlsson has proposed an approach termed "cognitive diagnosis" which uses a form of heuristic search to find plausible sequences of actions that lead from a multicolumn subtraction task to a known solution (Ohlsson & Langley, 1988). We have developed an application of cognitive diagnosis to a different domain from the one for which it was originally developed. The system solves simple electrical circuit problems (Caiger, 1990). The re-implementation has raised a number of questions about the cognitive diagnosis technique and its general applicability. We briefly discuss these issues in terms of future utility of the technique. |
