Surely his failed exam reforms are all we need to know he's a pile of crock.
He wanted to ditch GCSEs for his bacc programme. Except, the teachers, the head teachers and the association of businesses in GB opposed it. He dismissed this as a bunch of whiners. 21 university lecturers and specialists in education wrote an open letter explaining why his plans were wrong. He dismissed them out of hand. Didn't he also refuse to admit that the head of OFQUAL opposed his changes at a select committee, if I recall correctly. Then the head of OFQUAL published the lettter, highlighting very grave concerns about his plans, and so finally once he was faced with the fact that teacher, schools, businesses, professors in education and the examination authorities all said publicly and repeatedly he was wrong did he finally back down.
Now he is wanting to ditch the AS level, despite the universities and the teachers saying no, that they work. Oxford and Cambridge have both publicly condemned his reforms (that he claims will improve education) as detrimental and a backwards step.
Why do I hate Gove? Because he comes up with ill thought through ideas and refuses to listen to those who do actually know what they're talking about!
