There's More to Schools than Teachers
It is fast becoming a received truth that teachers, teachers, teachers make all the difference in a child's academic performance. But what if analysis of students' scores on state tests threw that belief into question? It may have in L.A.
That's not the impression you'll get from the recent L.A. Times story on teacher quality. The Times used student test data to estimate 6,000 L.A. teachers' relative effectiveness. The story suggests that it's all about the teachers:
Year after year, one fifth-grade class learns far more than the other down the hall. The difference has almost nothing to do with the size of the class, the students, or their parents.
It's their teachers.
But blogger Corey Bunje Bower had a look at the report behind the Times analysis, and he drew another conclusion. The Times notes that the best teachers aren't all crammed into the "best" schools. Bower weighs the implications of that finding:
Teacher quality varies widely within schools--just as with test scores, there's far more variation within schools than across schools. ("Teachers are slightly more effective in high- than in low-API schools, but the gap is small, and the variance across schools is large"). Which means that the highest performing schools don't have all the best teachers and the lowest performing schools don't have all the worst teachers. Which means that something other than teacher quality is causing schools to be low and high performing. Which means we should probably focus our attention on more than just teacher quality.
Of course teachers are very important. Why would anyone teach if teachers didn't matter? But should we put ALL our eggs in the teacher basket?
Other bloggers have raised strong objections to the L.A. Times piece. Can we trust the tests? Can we trust "value-added" analysis of test scores? Is it right to publish names and even pictures of ostensibly ineffective teachers in the paper? Is it legal? Is it fair? Will the Times' tactics pit teacher against teacher? Will the threat of public humiliation make it that much harder to recruit new people into the profession?
Those are all important questions. But Bower's suggestive analysis shouldn't get lost in the scuffle. It deserves more attention.
