I have even visited schools of education and have seen first-hand the stupidity behind the miserable test scores and substandard academic performances. What teachers are really saying is that they cannot understand how anyone can possibly disagree with their views. Such blind dogmatism is especially dangerous in people who are supposed to be teaching young people how to think. The most positive thing we can do for American education is to replace the kinds of teachers we have with better educated and more intelligent people. Private schools have no problem doing that because they are not tied up in red tape or in laws that enable teachers' unions and the schools and departments of education to keep out people who have not jumped through their hoops.
Studies show no correlation between education courses and teaching success.
Many private schools don't require such courses and some don't even want to hire people who have been through such drivel. As for the teacher who wanted me to tell her what to do in the classroom, that is not my job. My job is to try to help inform the public, so that they get teachers like her out of the classroom. Nor is more money either necessary or sufficient to attract better people. Private schools get better people while paying lower salaries than the public schools.
