We compared two automated approaches to teaching distinguishing, a fundamental skill of case-based reasoning that involves assessing the relevant differences among cases in a context-sensitive way. The approaches are implemented in two versions of CATO, an ITS designed to teach law students basic skills of casebased legal argument. The original version of CATO employed a didactic explanatory di...
