We recently had an inset in our school to which a speaker by the name of Geoff Hannan gave a compelling lecture to students, parents and teaching staff about the differences in how boys and girls learn. He was very entertaining and seemed to capture the students imagination quite quickly. Some of his concepts didn't seem new in anyway but it was very interesting to hear some of the science behind his methods and reasonings. I'm not going to say too much more but I highly recommend reading the sites below and seeing one of his presentations live.
This is an article from the Times Education Supplement (TES) that discusses Geoff and some of his techniques. http://www.tes.co.uk/article.aspx?storycode=311424
This is another website that sites Geoff Hannan's work along with others and discusses and suggests ways to improve boys attainment.
