Boys' Crisis?

The Washington Post has an article on a study done by the American Association of University Women on boys' performance in schools. The report questions the assumption that there is a crisis in boys' education and argues instead that social class is a much better predictor of underachievement.

I find this article interesting for a number of reasons, but primarily because it calls into question many things I've observed the past few years. For the little I've read of the report, it seems pretty convincing and soundly researched, but I still have the sense that boys just aren't performing at the same level as girls. But the report says that that has been the case for quite some time.

This is one of those liberating moments when I just don't know what to think about the whole issue. What do others think about this issue?
