I attended U of Illinois - Urbana-Champaign as an undergrad. I'm at UC-Berkeley now. A fellow grad student here went to Lewis & Clark. I voted for L&C because it's a smaller school where you're more likely to get a good education. While the graduate programs at UCB and UIUC are fantastic, the undergrad programs blow because you are just a number. UIUC has a little bit better undergrad program than UCB in my opinion, having seen both of them, but that's not saying much. I'd definitely go small for undergrad and big for grad school. If I had it to do all over again, I would have gone small instead of big for undergrad. I've heard Stanford is excellent that way.
A side note: if you meant by 'chemical education' that you were looking to get into the field of 'Chemical Education', UIUC is by far the best choice. Their education curriculum is fantastic, and one of the profs there, Dr. Don DeCoste, is not only an excellent teacher, but he does a tremendous amount of work with the 'Chemical Education' curriculum, thus ensuring it's quality. However, if you were referring to the chemistry education, then my former comments stand.
One more thing: make sure you like the area and don't go to a school based on reputation alone. The west coast is a tremendous culture shock to someone from the midwest like myself. If you're from the west or east coast, it may not be that bad, though.
Geodome: I do object to adding schools to the poll because the original poster said he wanted comparisons between schools that he was looking at, not all of them. We're not trying to have a competition between schools here.
