At least they should be teaching the controversies related to TOE. That would be a good start.
Controversies? Why?
Controversies are disagreements not necessarilly based on fact..
If you were to say " At least it should be mentioned (taught) what science doesn't know about evolution" I would agree..
But there is a preponderence of evidence that points to a logical conclusion, and many theories have been proven to be correct..
Denial of fact, empirical evidence, is not Intelligent..
