There are a variety of cancer organizations and medical institutions that will accept donations towards cancer research, including Hospital, the National Breast Cancer Foundation and the Cancer Research Institute.

But it seems like 3 or 4 years ago VAM was the new new thing, and now we're debating what "percentage" of a teachers evaluation they should be. If there's a body of literature that shows what the "noise" from year to year is, or whether there are interesting unintended consequences, I haven't seen it.RDThttps://www.blogger.com/profile/08566356038836885187noreply@blogger.comtag:blogger.com,1999:blog-5458172893016186479.post-33417091175216443702012-09-29T14:28:15.062-04:002012-09-29T14:28:15.062-04:00Oh, puhlease.

The question is, do they have any power?<br /><br />If there were two doctors, working in the same practice and each seeing a hundred patients a year, and one doctor had an average shrinkage rate of 75% and the other doctor had an average shrinkage rate of 25%, I would have no problem in paying the first doctor more, and saying that there is a very good chance she is a better cancer doctor.<br /><br />Each of the doctors will be powerless to do a lot of things that would improve their patients' health, but those things average out.<br /><br />It is an empirical question just how much "better" one teacher is than another. There's a lot of randomness in life and teachers' value added scores are going to bounce around year to year. Only by doing the experiment and looking seriously at the results will we see if some teachers consistently outperform others--and whether the difference is worth extra money or perks.Roger Sweenyhttps://www.blogger.com/profile/12734128265493099062noreply@blogger.comtag:blogger.com,1999:blog-5458172893016186479.post-1530060007784310722012-09-28T17:55:22.796-04:002012-09-28T17:55:22.796-04:00I'm coming increasingly to believe that one of...I'm coming increasingly to believe that one of the over-arching problems facing education today is the speed with which "interesting ideas" get turned into "solutions" by policy pundits.<br /><br />Value-added is certainly a step forward from raw test scores as a way to evaluate schools and teachers. But it seems like only days elapsed between when VAM hit the literature and when it was adopted by reformers as the next silver bullet.RDThttps://www.blogger.com/profile/08566356038836885187noreply@blogger.com
