Seeding long-term, sustainable change in teacher preparation programs: the case of PhysTEC.

Background: The continuation of teacher preparation activities after a 3-year Physics Teacher Education Coalition (PhysTEC) grant is used as a case study to examine multi-faceted aspects of sustainable change in higher education. Since teacher preparation is outside typical physics departmental activities, success is highly dependent on finding a department and institution who values this cause. Throughout the history of providing grants, PhysTEC has identified ten components of successful sites that they consider during the selection process.
