The advent of the literacy and numeracy hours mean kids do more not less than they did.
Boys can only do well in exams if they learn what is being taught that's a fact. They don't do better in exams unless they have retained knowledge, it's not instinctive.
A balance is good yes, however suggesting that students sre failing due to the gender of teachers is not right or fair.
Female teachers achieve the same qualification as their male counterparts, and are equally as competent.
