I really like your posts about education. There are a lot of things we learnt at school which in hindsight seems unnecessary and there are skills which most of us come out of school lacking.

If there is one thing I feel our educational system lack the most (at least from my experience) it is the ability to do critical thinking. When you consider whether what you learnt makes sense, questions are naturally triggered and questions most often bring revelation. I'm not necessarily saying that what we learn is wrong, but I get the feeling that a lot of graduates lack the ability to come up with own ideas, and become very dependent on the system which shaped their knowledge.

I also think its important for students to understand that disagreeing with the majority doesn't automatically make you wrong.

One last thing: In your list of skills students should learn at school, I would include some history as well.
