PiedmontSteward;
Your post sort of reminds me of the often-quoted union assertion of "a fair days work for a fair days pay", in which the union is always willing to quantify what a "fair days pay" is...but when it comes to quantifying what a "fair days work" is, it's a different story.
I see standardized tests like that, in that they're a necessary evil. Somehow, you have to QUANTIFY teacher effectiveness, otherwise there's really no way of objectively judging their performance. For example, in the case of the young teacher you mentioned, perhaps he was using some "innovative stuff", but when it came down to his students being able to demonstrate that they had learned "the basics" which standardized test place emphasis on - the essentials that EVERY student needs to know - he recognized that innovative stuff didn't cut it. Now I'm not saying that teachers shouldn't be innovative or creative, but if they can't bring their students around to learning the basics, then they need to be weeded-out.
Lastly, regarding you assertion that "Teachers in poorer school districts have kids that do worse on standardized testing", just why IS that? Granted, it may be true (and I'd be willing to judge teachers on the DIFFERENTIAL in such cases), but since when did "poorer" become an excuse for inferior academic performance? Maybe the parents ought to be made more aware that, simply because they're poor, that doesn't mean that their children should do poorly in school...and that, if they do, it's primarily THEIR fault. And if "poorer" families (I suspect in this instance, quite often - and unfortunately - a racial expression, given that "poorer" families of Asian and Eastern European background don't seem to have nearly the same problems with their children's academic performance) aren't willing to accept the responsibility of "bootstrapping" their children's education, then maybe it's time that society give up that goal as well...until such time as they ARE willing.
Sounds cold, I'm sure....but look what our education system has descended to. And I can't help but believe that the forces that brought it to that level are represented in large part by those out on strike in Chicago.
