Let's face it, we're going to see a massive outcry against the 'new' all linear GCSEs that are just starting once girls' results start to fall. Which, after all, is why the modular system was introduced.
IMO, I think we should have moved on a bit from the idea that all subjects should be, as near as dammit, examined identically. Some need to demonstrate absolute recall, some need to demonstrate how to use given information.
I was only talking to DH this morning about how, when we sat down to O level maths circa 1978, the very first thing you did when you were allowed was quickly, frantically write down all the formulae you had rote learned. Today, the DC are supplied with a formula sheet and I say good! I think it's more useful in the modern world for someone to be able to know how to access information (including checks on the veracity of information), and how to use it. We had question after question of 'straight' maths. Today's maths papers ask the DC to use their maths skills to solve problems.
In some subjects I think learning and using a set of skills, then testing that ability at the end of that module is just as valid as throwing a small cross section of the lot at a DC after 2 or 3 years. Yes, limit resits, allow all but no 'homework' (ie mum doing it), increase the 'formal exam' content, but don't get rid of modular learning!
Finally, tho I am not a suspicious or 'conspiracy- minded' person, I genuinely do wonder if Gove really is trying to feck up the life chances of state educated DC. It won't be the first time a ruling elite have done so. I'd like to think his -ahem- 'policies' are just misguided and ill-judged but I do wonder.
