It seems like an immensely complex issue. For example, they discuss in this article how while there are biological differences between boys and girls:

However, there is very little gap between what girls and boys can learn, and herein lies the rub. In fact, the differences are most pronounced in young children, and as children grow older, their home environment, their interests and their peers have the greatest influence over their behavior. By the time children are in the 12th grade, the differences between boys and girls are very subtle.

That being said, boys and girls do seem to lean towards learning in different ways - though not every boy will be an learner who needs activity and movement and not every girl is going to lean towards group work, language, and relationship-based learning.

Make sure teachers understand the different learning styles of boys and girls so that they are able to create a learning environment that meets the needs of both, by teaching different modalities that capture girls' needs for spatial learning practice, including geometry, and boys' needs for enrichment projects.
