Much of the discussion about 'what's working' suggests that students learn because the school is public, private, district, charter, parochial or whatever. This is bizarre: Clearly, students learn from what goes on in the school; from its curriculum, pedagogy, materials and teachers. The discussion falls back on 'jurisdictional status', becomes simply political, because we have no set of concepts, no language, that lets us talk about schools as schools. The field of education research has never -- astonishingly -- developed a systematic and orderly way to describe and classify the subject of its study. Now, working with Education|Evolving and with help from the Spencer Foundation, a University of Minnesota researcher developed a framework that sets out characteristics and variables that researchers and evaluators can use. Hopefully, next, researchers will 'go out into the field and collect specimens' and organize these to create at last a taxonomy of schools. This becomes more and more important as schools become more and more different.
