BCS:
> At the other end, if the professor *only* lectures on what's in the book, 
> what are they being paid for? Just talking? Better would be for the professor 
> to lecture on application, the what/why (and not the how), how ideas are 
> related, anecdotes and the like.

Books are meant to be read before taking the lesson.
Among other things, a teacher in science/technical fields can:
- help students understand difficult concepts;
- give problems that require the student to invent some new idea or be creative;
- answer student questions.
