He calls this "supporting learners as users," and his main techniques involve providing large collections of examples and other help materials which to a large extent are provided by other learners in that community. The fundamental starting point for Guzdial is that users and learners typically have a big goal stack: they have high level, long range aims to do with their work domain, each subdivided many times and ultimately resting on a large number of small actions (such as moving the mouse, picking a menu command, etc.). If the small actions are automatic, fully learned ones, then the theoretical existence of the goal stack is of little consequence. However if those small actions are themselves problems requiring conscious attention and a search for information, as they may
