Worth the read: A good debate on using data to measure teacher effectiveness.
Measuring teacher effectiveness is complex, and I agree with the economists that if all evaluations are based on test scores, teaching to the test will increase, especially among the less effective teachers.
Unlike batting averages, most ‘official’ student test data is acquired only once a year. We’ve also seen some of the negative effects high stakes have had on sports. Also, unlike athletes, teachers don’t all peak at the same time.
I feel like I’m an effective teacher, but I’m not sure how to really assess that. I also feel I have a lot more to learn and plenty of room for improvement.
