It has long been known that male and female brains are different - that they mature at different rates and develop in different ways.
You only need to look at the way very young boys and girls play to see that often they like different things and approach things in different ways.
Experts say girls' brains are more wired up for communicating and reading emotions, while boys like moving, doing and solving practical problems.
Principal of the School of Emotional Literacy Dr Elizabeth Morris says: "Boys like doing things for a purpose and having things that are concrete and relevant to deal with.
"Girls will be happier with discussion, relationship building, team activities and reading."
She adds: "The teaching profession in primaries is dominated by women who, with the best will in the world, will tend to deliver a larger proportion of the curriculum in teaching styles that make most sense to them - and therefore favour the girls."
Girls tend to be auditory and visual learners whereas boys are more kinaesthetic learners.
This means that while girls like to listen and watch, boys like to learn by doing and taking part in discussions in small groups.
