Don't rush to, or through, calculus

Today the New York Times published a letter to the editor by a Middlebury College professor that echoes the concerns in our article The Calculus Trap. Specifically, from the letter in the Times:
Quote:
More problematic, however, is the rushing through high school mathematics to get to A.P. calculus, while simultaneously accumulating A.P. courses in other areas...At the end of all this, a number of bright, hard-working students have shockingly weak algebra skills...Having used their A.P. credits to get into Middlebury, a number of our students try to take calculus again, saying, “I know I got a 5 on the exam, but I didn’t really understand it.”
We certainly agree. To take one example that the letter writer mentions, the rigorous definition of a limit is not part of the AP Calculus curriculum. Nor, I suspect, do most AP Calculus courses cover the proof of the Fundamental Theorem of Calculus, which is the most fundamental (duh) part of the calculus.

If you are satisfied with just using calculus as a computational tool, then AP Calculus may be adequate. If, however, you want to understand calculus, the AP curriculum will not do much for you.

Rest assured, our calculus course includes both $\delta$ and $\epsilon$.

The last line made me laugh...

The algebra and precalculus classes at my school aren't much better, since most of time is spent doing tedious computation and graphing (why is it allowed to teach graphing parabolas without knowing how to find the vertex?!).

I think most students just take AP calculus for the AP credit (looks nice on a weighted GPA apparently). Then those who are actually serious about learning calculus well self-learn or take an outside class for all the rigor. Those students probably already developed a better algebra foundation by themselves. On the other hand, if parents are pressuring their children then it's another can of worms. I'd say that by itself is more serious than kids not learning what a limit is properly.
