The Allure Of Teacher Quality


One question you do not pose, but would seem quite worthy of multiple posts, has to do with the entire list of approaches. Why is the US pursuing strategies to improve teacher quality in ways vastly different than all of the countries with greater international performance than the US? If policymakers are going to fixate on international test scores, perhaps they should pay attention to what other countries have proved already works. It seems the US is trying mightily to show that a free-market approach would work when none of the top-performing take such an approach. Having just listened to multiple spokespeople from the US Department of Education fail to provide and research evidence for the approach they are taking, one has to wonder what it would take for the US to seriously consider trying approaches that have actually been shown to be effective.

I think the field (and especially policy makers and advocacy groups) are in the middle of committing a huge fundamental attribution error. Too many people are framing the issue in terms of teacher quality, when it should be about TEACHING quality. Yes, the two are related but they are not the same. Too many policy discussions and research studies treat teaching as a black box and assume that it is enough to ensure that every student has a “good teacher,” as if mere exposure to a good teacher--placing students physically in the presence of a teacher and absorbing knowledge like light rays--is what brings about learning. Good teaching is not simply a function of good teachers, and the practices that teachers employ are not merely a function of their individual knowledge, skills, and experiences. It is also a function of the "technology" of teaching that we employ (curriculum, pedagogical models, teaching methods, instructional materials and tools), and the organizational structures and social resources in which teachers' work is embedded. One of the barriers to improving US education is the individualistic culture, and the heroic images of teaching in our culture. More than many other cultures, Americans believe that good teachers are born not made, that they are function of certain personal characteristics rather than the product of training. You either got the teaching knack or you don't. And also, it's rooted in American anti-intellectualism that sees teaching as easy work ("Those who can do, those who can't teach.") As the other Ed pointed out, other countries have done a better job of improving teacher quality by using training to reduce the variability in TEACHING PRACTICE. Yes, many of them have also recruited more accomplished college graduates into the profession by making teaching a higher status occupation, but they also invest (as other professions in the US do) more in ensuring that all teachers are rigorously trained to enact a set of pedagogical practices. In other words, they reduce variability not through selection but through training. Well, and also having national curricula helps, too.

Matt, I think your list has neglected the most powerful strategy for improving the quality of teachers--developing the capacity of school-site teams to continually improve instruction. There is quite a bit of research showing that teacher conversation around instruction trumps every other approach(even more powerful than the influence of socio-economics). For example, See Also impressive are the results from instructional collaboration in successful districts and states such as Mass., Ontario, Canada, Long Beach, Sanger, and the Aspire charter network and from high-flyers internationally. In all of these places, developing successful school teams focused on improving instruction was the hall-mark of improvement efforts and such approaches offer effect size gains many multiples of any strategy you listed.

I agree with Ed Liu's comment re fundamental attribution error and variability in teaching vs teacher - there is a BIG difference that policy-makers aren't recognizing. We should be re-evaluating the TEACHING PROFESSION, not teachers. The teaching profession, as others have noted, is extremely weak - not a profession in the true sense as it has little authority, expertise, or ability to peer-review its members. Because of this, TEACHERS themselves are weak in much the same way that disadvantaged students are under-performers: both are products of a weak system. SO, isn't the solution to reevaluate the profession itself - how it screens, regulates, develops, and supports its members? The focus should be on the profession, not the teachers.
