I heard a science teacher recently explain how they were moving away from what he called 'factually based learning' towards the concept of 'broadening the learners' imaginations and encouraging them to...' I can't remember the rest as I stopped listening, started drinking furiously and immediately labelled him as a fool.
People who invent things invariably have a huge in depth knowledge of their subject (self taught in many cases). Creativity is hugely over rated (the vast majority of inventions are simply clever modifications of existing devices and new scientific theories tend to be incremental advances by people tinkering with the current rules and equations. Most successful businesses also just copy an existing idea and do it better).
People are best persuaded to become entrepreneurs when they feel they might benefit from the results, rather than having to pay all their profits in taxes to fund an army of public sector box tickers. (Actually we shouldn't be trying to persuade people to risk everything in their own business venture when the vast majority would be better off working for someone else. I think entrepreneurs are more born than made.)
As for critical thinking- well, I'm afraid that the opinion of someone who does not know about their subject is utterly worthless. (But don't let that put you off reading my blog)
