I agree: the generous use of “master teachers” is the best way, not classroom instructions. You learn to teach by watching good teachers and by teaching.
Our experiences—Will’s as a member of Teach for America in Philadelphia and an education master’s degree candidate at University of Pennsylvania, and Michael’s as a researcher and writer—confirm what these statistics suggest: that all the money we spend on new teacher training does little to boost the quality of our beginner teachers. Fortunately, there’s a better, less expensive way to train teachers: an apprenticeship model.
Teacher apprenticeship can take many different forms, but at its core it means pairing a beginner teacher with an experienced “master teacher” who can both demonstrate effective teaching techniques—a good transition between a lesson and independent practice, for example—and then help the beginner adopt these techniques, reflect on them, and eventually forge his or her own unique style.
