Girls think they are cleverer than boys from age four, study finds Education The Guardian

The article states:

The study – Gender Expectations and Stereotype Threat – will be presented to the British Educational Research Association's conference tomorrow.
The paper argues that teachers have lower expectations of boys than of girls and this belief fulfils itself throughout primary and secondary school.
Girls' performance at school may be boosted by what they perceive to be their teachers' belief that they will achieve higher results and be more conscientious than boys, the academics claim. Boys may underachieve because they pick up on teachers' assumptions that they will obtain lower results than girls and have less drive."

With just a cursory glance this research warrants a good think by educators and parents.
