developed by Dr. Rueben Peuntedura, and is often known as SAMR. The acronym stands for four levels of tech implementation: Substitution, Augmentation, Modification, and Redefinition.
Rather than describe SAMR again, I'll just embed a video of Dr. Puentedura describing it himself. In addition, he discusses two other models of tech integration: TPACK (Technological Pedagogical Content Knowledge), and one that he doesn't have a name for yet.
This a a GREAT, concise 13 minute description of how one might think about effectively transforming teaching and learning with technology.
|I particularly like this "focusing layer" he describes at about 11:20.|
