A recent article proclaims that “The findings of several recent studies by psychologists, economists, and educators show that—despite many reformers’ claims to the contrary—it may be possible to make low-performing teachers better, instead of firing them.” (“How To Build a Better Teacher http://tinyurl.com/cnnl2pn)
Why would we think otherwise? How has the debate over teacher quality lost track of how excellence is developed in any field? It takes time, targeted practice, and the right support!
First, it takes 10,000 hours to reach excellence, as Malcolm Gladwell so eloquently documents in Outliers. That’s 10,000 hours–about 8 school years’ worth–with the right sort of coaching and support. Let’s be clear, too, that only actual teaching, lesson planning, assessment construction and analysis, and other core responsibilities count toward those hours, not preservice theory work (although that may guide practice).
A compilation of over 100 studies from many disciplines revealed, “When most people practice, they focus on the things they already know how to do. Deliberate practice is different. It entails considerable, specific, and sustained efforts to do something you can’t do well—or even at all.”
