Maybe the teacher is just trying to give an idea that there will be some different types of "questions" on the test, and if she gives some of these ahead of time, the ones on the test won't seem so odd? interesting....

Another thought - Maybe they are doing some sort of an LD or vision or "type of learner" screening too? I have absolutely no idea if optical illusions would be related to anything like this, but just throwing it out there.

I had fun with your links though! It brought back a memory of my first oral report. For some reason i picked optical illusions.
