Am I a geek or a nerd?


Is this a dead horse I’m beating?

I belatedly finished Diane Ravitch’s Death and Life of the Great American School System (I link to B&N because I have a Nook…we actually have three Nooks in this house…for two people who are able to read…and a tablet…and a netbook…heavens…) and while I’m pretty sure I knew the basics of much of her position, that she provides citations and research to debunk myth and illustrate our dangerous ways makes this a nerdy/geeky delight.

Read it yourself for the full poop; I’m still thinking about the prospect of using student test scores to evaluate teachers. Ravitch provides much info, but the piece I’m most struck by is this study: “Error Rates in Measuring Teacher and School Performance Based on Student Test Score Gains.” In short, the USDE commissioned a study that found that error rates in determining effectiveness of individual teachers range anywhere from 25 to 35 per cent depending the variables (number of years scores are collected for example). This was released in July 2010. One year prior to this study Race to the Top was announced and in part required states to use student scores to evaluate teachers. Hmm. I poked through the study document and found citations dated 2010, so my assumption is that this was commissioned sometime in 2010. So USDE demanded an action of states and at the same time paid for a study to see if that action was really effective. Then it turns out that the action doesn’t seem to be a great option but they keep on keepin’ on with the demands.

I get that scores will just be one part of evaluation for teacher here in NY, and I get that we don’t have a great system in place now (see here, here, here and I’m sure I’ve mentioned more than that and for some other great links and commentary on this, here), but I really don’t think I want any part of any evaluation to have an error rate of 25%.

I’m still trying to be unsurprised by the blindness of everyone barreling down this road.
