-I don't think anyone is surprised that the article claims that boys perform better under conditions which simulate actual adult workplace conditions.
-A bigger issue is really the education system targeting the median student. That means those students with the highest potential have to fight against the system to reach it -- if they ever reach it at all. And holding back the brightest people, when the economy is advanced by that small percent of bright people, sounds horribly ineffective.
This educational system is an artificial structure imposed on people with disparate learning capabilities, trying to fit every peg under the sun into a square hole, and I think we've missed out on a lot of value because of that.
Hopefully, as automation increases, this is something we'll be able to improve upon.
