Yes, and I also received a personal reply from Mr. Luteman admonishing me for my "glibness" and informing me of the high level of achievment expected and obtained at the institution where he teaches, of which I have no doubt.
I received only two A+s in my entire time in high school. One was in probability, the other in trigonometry. I was subjected to countless quizzes and tests of the type described in the original post. I happen to be good at taking tests. I must confess, here in NCTML for all to see, that at the present time I remember virtually none of my trig  were I required to teach it I would have to learn it all over again first. I consider it my responsibility to my students try my utmost to present material to them in such a way that they might not only retain it, but perhaps even enjoy it.

Again, having set all glibness aside, I agree. I'd like to ask Kent a serious question or two now. How much class time *do* you spend on this, and more significantly, how much are these quizzes weighted in evaluation? Are they diagnostic, or summative? Are they also used (formally) to evaluate the effectiveness of the program?
I did not mean to suggest that quizzes are a priori wrong  indeed they are a usefull tool that I employ quite liberally. However, I would weight one word problem in which students had to choose correctly from six (or more) methods to solve a problem (or just invent one that works) more heavily than a semester or a year's worth of highstress, lowcognitivelevel quizzes. I would also suggest that there are *many* other ways to practice algorithms and to assess students' mastery thereof.
