The last college I taught at had a similar set-up for Introductory Biology with McGraw Hill's Connect software. I was very unhappy about the cost to the students, but felt obligated to make it worth points, since students who were forced to use its adaptive learning system in previous years performed better than those who weren't.
I really wish there was a free or open-source adaptive learning system for biology courses, in the same way that the Khan Academy has one for learning math.
