There's a very engaging discussion in The Economist. The question is "How has the crisis changed the teaching of economics?" The answers are provided by some very well-known names in the profession. And while it really doesn't address what is done in the high school as much as it addresses the collegiate and graduate level, it still makes for good reading. I find it particularly interesting that many of the respondents think there should be renewed emphasis on economic history as a component in collegiate studies.
At the very least, I suspect it's made high school students a bit more curious about what happened and why; and perhaps more interested in the course. Is that your experience?
