"SAMR model is a conceptual framework developed by Dr. Ruben Puentedura to help you better integrate technology in your instruction. SAMR stands for Substitution, Augmentation, Modification and Redefinition. Each of these four levels correspond with a set of tech-based activities and learning tasks. The strength of SAMR model is that it provides teachers with a robust method to gauge and assess the efficacy of the technology they and their students use in class. Check out this section for more resources on SAMR."
