This is absolute bollocks. I totally agree with you ISNT, and Pogle, 50/50 is fine, that way learners have to develop skills in both research and memorising facts, which seems good and useful all round. Agree also that the coursework version will become "second class" and girls will get kicked in the teeth once again by a system that only panics when girls are outdoing boys.
I cannot explain how stupid and irritating this "girls prefer x, boys prefer y" thing is. They always mean "on average more girls prefer x, more boys prefer y", and when it comes down to figures you'll find that something like 56% of girls prefer x, and 52% of boys prefer y. Invariably some idiot then generalises this out to say that, in that case, all girls should do x, all boys should do y. Well what about the nearly half of boys and girls who don't fit in with the "majority" of their gender? If it was 99% correlated with gender it would make sense. This is just crap.
Also, it sounds like they are attempting a double whammy - improving boys' results by not making them do actual pesky work except for the exams, and lessening girls' chances by not having them sit exams. This is wrong, if girls are doing better at the moment the answer is to improve boys' grades somehow, not to put a hobble on the girls who are doing so well with the current methods of examination!
