How coaches influence student achievement

A fabulous article by L'Allier, Elish-Piper and Bean in the April 2010 edition of The Reading Teacher describes how literacy coaches improve student performance... highest gains were reported with students whose teachers worked with coaches who spent most of their time working with teachers, as opposed to other activities.... makes sense. But the good news is that over time coaches begin to spend more and more time in "teacher-centered" activities....It seems that it often takes as many as 3 years to build those collaborative relationships!!! Read it and comment about what you think....
