I posted an article a few weeks ago about Bill Gates and his thoughts on education reform. The thread got a little crazy, but I found a very interesting follow-up article about the teacher evaluations the Gates Foundation is trying to develop. The group is looking into evaluations that are based on both test scores and observations (most likely video observations). What impressed me: a desire to focus on what good teachers do WELL and to use that information to help other teachers improve. What still confuses me: what if you don't teach a tested subject? Also, how are video observations done? My department uses a video observation system, but we are usually aware beforehand that we will be taped. I like it, but if it were random, it may be scary (although I suppose that would be an effective way to evaluate teachers). Here's the article: http://www.nytimes.com/2010/12/04/education/04teacher.html?_r=1&ref=education What do you all think? The research isn't completed, but could such an evaluation system weed out ineffective teachers?
