Comments on: Performance Measurement vs. Analysis http://www.gilliganondata.com/index.php/2009/02/15/performance-measurement-vs-analysis/ Thoughts, musings, and, hopefully, not too many redundancies on the world of business data. If you missed the irony in the previous sentence, you may struggle with my writing style.

But...not just your performance -- the performance of all of their students. The assumption (which is highly problematic in its own right, but I'm pretty sure my stats professor isn't going to ever read this post, so I'll run with it) is that calculus teachers all get a roughly similar distribution of talent across their student pool. An inherently low-performing student should still perform better with a great teacher than with a lousy teacher. Actually, The New Yorker had a great article by Malcolm Gladwell a few months ago (http://www.newyorker.com/reporting/2008/12/15/081215fa_fact_gladwell). Salient quote from the article: "Eric Hanushek, an economist at Stanford, estimates that the students of a very bad teacher will learn, on average, half a year’s worth of material in one school year. The students in the class of a very good teacher will learn a year and a half’s worth of material." But...this post wasn't really meant to be about my take on the woes of the American public education system!

How does your achievement test define a bad teacher in the first place. I had numerous instructors in Calc and Stat classes that may have been good teachers and could probably do well on the achievement test. Problem is I could not understand a word they said because they were not of American descent. Wouldn't lack of communication classify them as bad? But that is not a testable quality. Or maybe it just made me a bad student, which is highly likely at that point in time. OK Tim, throw a kink in the theory. How does your achievement test define a bad teacher in the first place.
