Friends, Hanushek appeared recently (September?) at a public forum organized by the UC Berkeley School of Journalism to address the controversy over the LA Times' infamous publication of individual teachers' "effectiveness"ratings based on test scores. That's the publication that provoked Rigoberto Ruelas' suicide because he dared to teach difficult students. Somebody posted the links to the videos of this forum on this list. I describe the video of the opening panel. Hanushek was on an expert panel about the technical aspects of value-added (VAM) teacher ratings, and in my opinion, he came across as reasonable and an expert on educational measurement because he was able to focus on some of the narrower weaknesses of the current application of VAM, like the sloppiness of attributing scores to the wrong teachers, the failure to consider ALL of the teachers teaching a child (not just the teacher of record), the unreliability of year to year scores, etc Hanushek admitted to the fact that such weaknesses needed to be "fixed" but was able to defend VAM as a necessary and useful approach to improving our schools. In effect, he made teacher bashing look legitimate. Within the narrow context of that panel's discussion, I think the general public got the impression that an improved VAM is a necessary tool for real education reform, especially for poor minority kids. In other words, more grist for the corporate standardistas' teacher bashing propaganda mill, more spin for their bogus civil rights ploy. On this panel, there was not sufficient discussion of the fact that the REAL causes of low test scores, and of kids' weak learning, are poverty and the narrow behaviorist teaching that has taken over in low income schools. There was insufficient criticism of the use of standardized tests to measure learning. The two Berkeley professors, good people and true experts, may have mentioned these criticisms, but I just don't remember because the whole premise of the panel was a set-up that gave an ideologue like Hanushek undeserved respectability. As a minion of the conservative corporate hypocrites, who now clamor for "deficit reduction" as they promote astronomical war spending, Hanushek has played with statistics unrelated to teaching and learning to argue for twenty years that "schools don't need more money" His writings are a part of the CAUSE of low achievement in working class schools. They have been used as a justification for the deliberate underfunding of public schools that began under the Reagan revolution. The point is, UCB School of Journalism, you can't give right wing ideologues a free space in which to look legitimate. Their false premises (school funding is unimportant, teachers are the prime cause) should be frankly addressed and exposed BEFORE they are given a platform to spin them. Those of us who know the truth about education and the politics of education must take any limited opportunity we have to highlight the real issues, as Stephen Krashen does below, and not get drawn into technical debates that legitimize the standardistas' lies, like how best to use standardized tests to fire teachers. Pete Farruggio ----- Start Forwarded Message ----- Sent: Wed, 3 Nov 2010 20:16:04 -0400 From: Stephen Krashen <noreply@sdkrashen.com> There has been a change in strategy: supporters of value-added and making teacher evaluations public now admit that there are problems but think that they can be easily fixed. The relevant section of the New Jersey Star-Ledgrer's editoral: "In New York, the teachers union filed a lawsuit to block such a release saying errors are rampant: Some teachers were scored based on students or classes they never taught, and there’s a high margin of error. Unpredictable swings rank a teacher in the top tier one year and near the bottom in the next. If true, that must be fixed." I suspect that this confession comes from Hanushek's article in the NY Daily News, available at http://susanohanian.org/show_nclb_outrages.php?id=4065 . My response: Fixing value-added evaluations: Not our first priority Sent to the NJ Star-Ledger, November 3, 2010 The Star-Ledger feels that value-added scores, the gains a teacher's students make in a year on standardized tests, should be released to the public (Nov. 2). The Star-Ledger recognizes that there are problems with using value-added scores, and states that they must be "fixed." It's not that simple. Studies show that value-added ratings are unstable. Value-added ratings based on one year are weak predictors of value-added ratings the next year. A teacher who succeeds in boosting scores with one group will not necessarily succeed with others. Studies also show that different reading tests result in different value-added scores for the same teacher. Value-added ratings may not represent real learning. There are ways of pumping up test scores without student learning, including teaching test-taking strategies and making sure weak students don't take the test. It would take years of hard work and major financial support for research to fix these problems. Our schools are facing tremendous financial problems: In high poverty areas, science classes lack equipment, libraries lack books, and even bathrooms lack toilet paper. Funding complex and subtle studies to attempt to create what might or might not be a better teacher evaluation measure is not our first priority. Stephen Krashen
