For faculty who really want a good understanding of student-centered instruction as well as assessment, I higly recommend this book.
It is replete with examples and the section on developing and using rubrics is exceptional.
I consider this book a must have for faculty member's professional library.

A gangster assembled an engineer, a chemist, and a physicist. He explained
that he was entering a horse in a race the following week and the three
assembled guys had the job of assuring that the gangster's horse would win.
They were to reconvene the day before the race to tell the gangster how they
each propose to ensure a win. When they reconvened the gangster started with
the engineer:
Gangster: OK, Mr. engineer, what have you got?
Engineer: Well, I've invented a way to weave metallic threads into the saddle
blanket so that they will act as the plates of a battery and provide
electrical shock to the horse.
G: That's very good! But let's hear from the chemist.
Chemist: I've synthesized a powerful stimulant that disolves
into simple blood sugars after ten minutes and therefore
cannot be detected in post-race tests.
G: Excellent, excellent! But I want to hear from the physicist before
I decide what to do. Physicist?
Physicist: Well, first consider a spherical horse in simple harmonic motion...
Actually, the probability is 100% that the elevator will be going in the
right direction. Proof by induction:
N=1. Trivially true, since both you and the elevator only have one
floor to go to.
Assume true for N, prove for N+1:
If you are on any of the first N floors, then it is true by the
induction hypothesis. If you are on the N+1st floor, then both you
and the elevator have only one choice, namely down. Therefore,
it is true for all N+1 floors.
