Technological Pedagogical And Content Knowledge (TPACK) is a framework to unde
rstand and describe the kinds of knowledge needed by a teacher for effective pedagogical practice in a technology enhanced learning environment.  The idea of pedagogical content knowledge (PCK) was first described by Lee Shulman (Shulman 1986) and TPACK builds on those core ideas through the inclusion of technology.  Punya Mishra, professor, and Matthew J. Koehler, professor, both at Michigan State University, have done extensive work in constructing the TPACK framework. is an active repository of news and information about TPACK.
