Barb, great, many thanks. The issue of providing a point (or more accurately a process) of engagement is an interesting one. If you are thrown in at the deep end (the edge of chaos) you will presumably only learn what you have to learn - that can be good, and efficient, or it could be bad and a waste of time, time which could better be spent on the 'meat' of the course itself.
You said there were 'two courses' here - how would the other one differ? Presumably there was a software learning course, and a culture and digital media course. If you mapped them both, and superimposed them, what would that show you (if anything?) And over the time of the course, would these two adjust relative to each other, and relative to the your degree of skill and comfort in using the software?
