There still has to be a way to measure performance for teachers, and there still should be a way to get rid of ones who don't do thier job. I get a yearly performance review in my job, and if I don't do what I get paid for I can get let go.
This is a problem endemic to public jobs in general, where it is far easier to find a "window job" for underperforming employees than get rid of them, forcing other people to do the bad employee's job, or force the government to hire more people.
If a teacher has no fear of losing thier job do to mediocrity, all you will get in 80% of the cases is mediocrity. There will be some who do thier job because of duty, but people, are people.
Marty,
You and I usually agree and I do agree with what you said in general. There are bad teachers out there who need to be weeded out and let go. That being said, there are so many factors in education that it is hard to do a cookie cutter comparison of teachers. I live a pretty good life and live in a nice neighborhood. I'm in that group of people who are referred to today as helicopter parents. Now, I'm not one because as a Boy Scout leader, I've learned to let kids do for themselves, but I fall into that group. We care about what our kids are doing and what they are involved in and that carries over to education. When my son was in grade school, we required him to bring his work home every night so we could check it and went over his homework as well. We never gave him the answers, we just pointed out what was wrong and had him do the work. That paid off. He just graduated high school with honors, received a scholarship to a university where he has been accepted to their honors college. He is naturally bright, but we made his education a top priority in our home. Even with a "bad" teacher, our involvement in his education gave him an advantage.
The other side of that coin is the inner-city schools where the kids don't do so well. They get the same textbooks, the same materials and the same facilities. They may even have teachers who are teaching their ass off, but the kids make bad grades. The difference, the support they get at home. Perhaps there is no dad and mom works two jobs. For a variety of reasons, some valid and some not, the parents of these kids just don't make education a prioroty and don't involve themselves in their children's education.
If you are a teacher, how do you combat that. Bad teachers with parental support whose kids are making good grades are viewed as good teachers worthy of merit pay. Good teachers with no parental support whose kids are making bad grades are viewed as bad teachers who need to be fired.
I worked for a cmpany once who hired a consulting firm to do a study. There were areas of the company who could benefit from such a study because those people did guantitative work where you could measure speed and accuracy. I was in a professional position where I did project work and no two days were alike. They wanted to measure me and my peers by the same standards as the widget folks and there really was no valid way to do that. This is how I see trying to apply a standard to a teacher. Too many variables to make it viable.
