I have been working to do this with a high(er) degree of granularity for a high school physics curriculum. The idea is to represent a student's unique journey through a topic space, and break free of the enforced and artificial linearity that a textbook's sequential chapters impose. Don't we all learn naturally by following our needs, or curiosity, through webs of knowledge, forging our own path to understanding? EDIT: Found one of my favorite quotes on this: "The student feels that, on his own, he wouldn't have followed the route he has just been led down; and he forgets that there a thousand paths in intellectual space open to his will." – The Ignorant Schoolmaster (Five Lessons in Intellectual Emancipation), Jaqcues Rancière
