When I did my first degree, a few of my lecturers pushed their own textbooks; it makes sense, no doubt, since it would be a work whose authority (one hopes) they would have full confidence in - but it also makes them money.
Now I’m starting my masters (MAVE at Sussex) I find that it’s iPhone apps that are being pushed! Shamelessly, I might add. I like this.
That really sounds like an interesting program. (MAVE, that is, not Dr. Phil’s magical time calculator program.)
