Concept Maps are an established technique within pedagogy (well, it has its
supporters, who are probably not very well supported). I believe the idea is
that if a student has true understanding of a domain area, they will be able
to construct a coherent concept map on the blackboard, whereas being able to
answer fill in the blank questions proves very little.
The circles are connected and the connections are also labled. For

Hugh Dubberly once made a useful point about there being two types of
representation: static and dynamic. In a static representation of baseball,
you diagram the players, bases, field, equipment, etc. In a dynamic
representation, you can make a flow chart of innings, plays, outs, strikes,
I think it is probably difficult to represent the static (concept map,
sitemap) and dynamic (task flow, scenario) on one sheet of paper. But I culd
imagine some useful cross reference, or even some kind of software tool.
Something like Director or FinalCutPro that has a sense of frames and
objects in a frame. Or like when they show a chess play as a sequence of
chess boards. What is the user seeing-thinking-doing at each step of a task.
