To teach paramagnetism in AP or not?

Actually, that’s NOT what I’m talking about here. This post isn’t about whether paramagnetism is (or is not) testable, rather it’s about some much bigger point. I think it has the potential to help inexperienced teachers. I hear a lot that ‘paramagnetism is no longer tested, because I did a search of the CED and […]

More, potentially useless Wordles

I recently re-visited the Wordles that I first produced in June of 2013 for the original versions of my AP Chemistry notes for Big Ideas 1-6. You can read about them here. Before I update those Wordles again to reflect the newer versions of the notes more than 2 years down the road (which I […]

Here’s a question that will be on the 2015 AP Chemistry exam

Well, maybe…..but probably not. Oh, I dunno! This evening, Paul Price led an AACT sponsored webinar entitled, ‘Reviewing for the AP Chemistry Exam‘.

As a result, students tend to score poorly on a […]
