We motivate and describe the design of a tool for exploratory learners. A task-action trace displays a history of user actions that collapses into verbal descriptions of task accomplishments, derived from a task-action grammar analysis of the interface. Previous tasks, and the actions through which the user achieved them, remain available for browsing; the display of actions shows those that were strictly necessary. We describe the implementation of such a tool for a simulation of the RATES line-diagnosis system. Preliminary empirical evaluation suggests that some users find the trace sufficiently helpful to interact with it repeatedly during the first 4 h of learning. |
