Sorry Stat, can't agreeYou are certainly correct that a system by itself doesn't teach much, but it is a system that ensures that the good teachers (i.e. those that can impart the knowledge and inspire confidence and learning to students) can thrive in a given school system and that bad teachers get rooted out. It is also a system that ensures that a curriculum is taught appropriately.
If a large number of students are (a) not learning what we as society think students should learn, and (b) there is evidence that students are "gaming the system", then that is a flaw in the system.
In our system today many of the best teachers leave and the poor ones stay.
I'm speaking from experience....
