If there's a specific reason behind the curriculum that puts women off from studying then it should be corrected. However I attended an all girls school from 11 - 16 and the science classes were smaller than, for example, the art, history or language classes - and you can't say that was because of any bias towards women since the entire year was female. Perhaps we should just agree that men and women are different, they have different views and different interests, and I disagree with trying to persuade anyone into studying something they have little or no interest in. Young people should be encouraged to examine their strengths and interests and choose their subjects accordingly, regardless of what gender they happen to be, and if that leads to an imbalance of the sexes in some fields then so be it.
