I'd like to point out that there is an A-Level in Critical Thinking, and I taught the version from the OCR board. My experience of it was not altogether positive, in that unless you overload the course to make it useful, the core of it does not address CT usefully. It has been described as a "pseudo-qualification", and one commentator has written:
But what I found most disheartening when reviewing the figures for A-levels was the increase in subjects such as "critical thinking" - especially as there were fewer than 1,000 students taking Latin or ancient Greek this year. Why is critical thinking even a subject? I can understand why A-levels come under flak when you need to be given a certificate telling you that you have the capacity to think.
My preferred approach would be for critical thinking to be split into various domains, with the government working with clever people like whats we can finds on this here forumboard. Then we weave these into specifications for all courses appropriately. All this is backed up by regularly focus on critical thinking issues that arise in news, media, politics, advertising etc. However, this would lead to an education system that educated people, and that's not exactly the point of it at the moment.
As an aside: I don't trust De Bono. His bullcrap, like 'thinking hats', is too often used by "blue sky thinkers" to provide a sheen of scientific legitimacy. Also his lateral thinking exercises, I have read, has not shown any effect on cognitive skills in empirical tests. Sorry I can't provide a reference for this, though.
I also don't trust Buzan. He somehow makes money teaching people how to mind-map... surely one book and you're done? He also claims to have invented it when really such techniques go back to the Ancient Greeks. The Ancient Greeks rocked and I'll have anyone that prefers the Romans!
In short, I am 'ornery and like to complain.
