The SAMR (Substitution, Augmentation, Modification, Redefinition) model, created by Dr. Ruben Puentudura, guides the process of reflecting on how we are integrating technology into our classrooms. The ultimate goal of technology integration is to completely redefine how we teach and learn, and to do things that we never could before the technology was in our hands. For more information, you can watch a series of podcasts by Dr. Puentudura, visit his blog, or read Dr. Puentudura's paper on the model (PDF).
The TPACK (Technological Pedagogical Content Knowledge) framework lays out the knowledge that educators need in order to successfully integrate technology into their teaching. The TPACK website provides a large collection of free resources for teachers and other instructional leaders.
