Project Zero is a research group at the Harvard Graduate School of Education. http:www.pz.harvard.edu/Research/Research.htm They have been investigating the development of learning processes in children, adults, and organizations since 1967. Oneof the outcomes of this extended study is the "Smart Schools" model, a set of seven guidelines for good education that is based on two guiding principles: 1) learning is a consequence of thinking--and good thinking is learnable by all students; 2)learning should include deep understanding, which involves the flexible, active use of knowledge.
