The teachthought site discusses a lot of the topics I am seeing brought up in this class, and in my other class. This article ties in to the multimedia aspect of non-linear curriculum. I like that it does not use too much "teacherese" so that the non-initiated like me can understand it.
Haven't spent much time looking at this, and it's not free... they were advertising for a Software Engineer. But it is an interesting resource, if only to see how for-profit industry is trying to supply goods and services to the education market.
