Oh, for fuck's sake, how is some Dave being jerk is making gender difference apparent? The guy was at the wrong place, and was being a show-off. But no, you must attribute it to his gender.
<edit> As pointed out by threads below, the author was talking about how the room tuned out when Dave started derailing conversation, and he saw it as call to arms. The author sees this as apparent gender difference - FWIW I don't agree with his assessment. As long as we are talking anecdotes, I couldn't see a clear patterns(based on gender or any other trait) in the reactions of the people I know to this scenario.
I am leaving my incorrect comment as there are replies, and the replies will become meaningless if I remove it. </edit>

I think you are better off not basing off your approach on some controversial study. If you are compartmentalizing, no two students are same. And if you are generalizing, I find it hard to believe that 3291805000 females of the world show the same behavioral and learning traits. Unless you have proved it otherwise, I would stick to a feedback based approach where I see how students are coping up, and then introduce variations.
