Hmm, well I went to a grammar school and was in the top form.
It was 50/50 boys and girls in the form.
We got half term and full term marks (which is course work I suppose) and then sat exams twice a year and got the end of year form order from the exam results.
As I recall the top 2 places in the form (and thus the year) alternated between a very clever girl and a very clever boy. They were both brilliant at every subject. Then we had subject specialists, top in physics was a very geeky boy who went on to Imperial and got a first, top in MAths was a girl (I was always 3rd or so).
Top in languages was a girl, top in history a boy...exams certainly did not favour one gender or the other.
But I think this silly thinking as per the article all stems from:
Only very clever people who can pass top exams get qualifications.
OK, so for those for whom O level is just too much lets introduce GCSE's
Oh look, we still have quite a lot of people getting no qualifications, lets make the exams a bit easier so people who are less clever still get a qualification and feel better
Oh, exams don't suit some people, lets add in a bit of continual assessment
Oh, now girls are out-performing boys...that's not fair, lets do something to adress the balance or boys will get despondent...
Let's not mention that girls mature more quickly than boys emotionally anyway, and physically so sitting still from age 4 and holding a pen is easier for them and that we actually have made the education system from day 1 more difficult for boys, especially as the old methods of getting boys to learn (feeding them brimstone and treacle and thrashing them if they don't try hard) are now gone. (I'm not saying these were good things BUT they were just as much an answer to boys not working hard during the year as giving them exam only course as is currently proposed).
Lets ignore the fact boys learn generally in a different way and need more attention and get more attention and that girls who sit and work steadily and quietly get less praise from the teacher than a lazy boy who then does one bit of work well
Lets also ignore the fact men will earn more when they leave education regardless of educational attainment
This is just papering over the cracks of a different problem (basic gender inequality in education and the workplace).
