So, how to educate children in a changing world? How to educate children to get into a world where most jobs have not even been invented yet? Complex? Yes, it is. It is impossible to prepare students to (or educate for) this changing world. At least with current "systems" of education. We have to bear in mind that we have educational systems that stem from the middle ages (with changes), with teachers trained in the 20th century but with 21st century demands. And the answer is not more exams or memorization (by the way, do you remember all you have memorized?). The answer is an education ("system"?) where everything is integrated; where you learn things through other things; and where you do (useful) things with the things you have learnt. At the same time, we should bear in mind that not everybody is good at (or should be good at) the same things.
I do not consider education "instruction. I would rather consider it "extraction"! Governments should aim at "extracting" student´s talents rather than "inserting" concepts into their brains.
