I have just done a lot of writing and researching about boys and the way the curriculum is failing them.
I have taken it from the angle ...
The Govt is pushing us to better manage the needs of boys... what is going wrong and how do we support them?
I have looked at nature vs nurture and then gone on to consider whether our curriculum meets their needs.
I like your thoughts about g & t as well. I am not sure how much research is already out there but what I think might be interesting to research is how children who are g & t interact with each other in mixed ability settings.
