I have worked for 30 years in post-secondary education. Evaluating teaching effectiveness is one of the hardest tasks that administrators have. Even metric that is commonly used has serious fundamental flaws which usually lead to some dysfunctional behavior as instructors attempt to game the system.
I am a Mechanical Contractor and Engineer. I can assure you it took a LOT of hard work to get that degree. I get a little tired of the teachers who throw that little diddy of their superior education and how hard they worked for it. While it is true they did receive a higher education, please see post no. 9.
Thank you. People don’t want to think about how hard it is to base teacher pay on merit. I like the idea, but have not ever seen a way that really works.
