You'd be surprised how many good teachers I know. I think it's one of those situations where a few of bad ones are so bad that it's easy to make a leap that they represesnt the majority of teachers. I have seen studies where they polled individuals and asked their general opinions of teachers. The answer where negative but when they asked a follow up question about the specific teachers they have had experience with, they same people's answers were very positive. For example my kids have had aproximately 15 teachers. One was not very good. Another was ok. But 13 out of 15 were great. And a few of those were so awesome that they drastically improved my children's lives. But it is far more likely to talk at length about the one negative experience. I have to catch my self and make sure if I do, I also talk about the great ones.
