SAMR and TPACK are two models of technology integration
SAMR is a model of technology integration comprised of four levels, two enhancing levels: substitution and augmentation, and two transforming levels: modification and redefinition. Technology can be integrated at all of them; technology used at the transformational levels transfers into a positive effect on student learning in other areas. SAMR can also be used to differentiate instruction within the same unit.
TPACK is a framework for integration which combines knowledge in content areas with pedagogy and technology. It provides a structure to identify how technology, content and pedagogy combine to support a variety of learning opportunities and to help educators choose the most effective combinations.Technological Pedagogical Content Knowledge (TPACK) attempts to identify the nature of knowledge required by teachers for technology integration in their teaching, while addressing the complex, multifaceted and situated nature of teacher knowledge. The TPACK framework extends http://en.wikipedia.org/wiki/Lee_Shulman Shulman’s idea of Pedagogical Content Knowledge.
