I see your point, easily actually. I think this will come down to how to figure out which teachers stink. I assume there are entrenched foes on that issue, especially complicated with testing testing and testing as the simple and prime standard.
I'm not sure where I stand on testing. We were tested six days from sunday; if anything, too damned much, but not from any standard the school was issued (I'm talking re what I call elementary school, 1-8).
I've whined in the past on a2k about my 1-12 years of, yes, catholic school, being too rote oriented. Few if any of us learned to argue at all, which was mirrored in our homes... leaving us who ended up at a public university somewhat gobsmacked.
All that rote was useful in it's timeworn way and I understand those who want to go back to that somewhat. Still, I think learning how to explore, question, learn, question again, not to mention becoming acquainted with syllogistic reasoning, should occur much earlier than I ran into those.
