"Give a man a fish; you have fed him for today. Teach a man to fish; and you have fed him for a lifetime."
Education is about learning how to think. It is only when a person can truly think and analyze her own process that he or she will become an independent life-long learner with the ability to be skeptical when necessary. We call the ability to analyze one's own thoughts 'meta cognition' in education lingo.
It follows that the emphasis on any education should be about teaching students to think, in a variety of disciplines... the more the better.
If you look at our system, at least in California, you will see that we teach students how to perform on multiple-choice, standardized tests. Thus we will have a generation of students who can perform well on standardized tests. I am fairly certain though, that this type of training is not teaching the students to think.
More on that later.
