The conclusions of such a survey seems to be that older teachers are just resistant to change and don't care as much about improved student learning. This is like saying that experienced doctors should be open to using patient death rates as a way of rating the effectiveness of doctors. However no one would question an experienced doctor's objection to this, pointing out that doctors who serve the most "at risk" patients are likely to have higher patient death rates. No doctor should be rated as effective or ineffective by such a stupid measure. But the reformers think its OK to treat teachers that way.
I just watched an interview with Bill Gates on the Fareed Zakaria show. For such a smart man, he sure is dumb about education. Fareed asked him if all the research his foundation had done had identified what makes a great teacher.
"Yes, it has!"
"So tell us exactly what it is Bill."
Bill Gates then kind of beat around the bush and finally said something about a teacher who is more interactive and is able to better engage students in the learning process. Big discovery! The problem is, Bill then goes on to talk about how if we would just spend about 2% of what we normally spend on teacher salaries to use data and new evaluation techniques to ID the best teachers and train or somehow get all teachers to perform like the best teachers, we would soon have the best education system in the world. According to Gates, its all about the teacher! Not one word about attacking poverty. Not one word about the lack of books in some children's homes. Not one word about parent responsibility. Not one word about ensuring discipline in all classrooms. With helpers like Bill Gates, public education does not need more enemies! See the Inconvenient Truth About Edcuation Reform in the Washington post. Now we are seeing much evidence that it is all about the money, not the children!
