"The SAMR Model is a framework created by Dr. Ruben Puentedura that categorizes four different degrees of classroom technology integration. The letters "SAMR" stand for Substitution, Augmentation, Modification, and Redefinition. The SAMR model was created to share a common language across disciplines as teachers strive to help students visualize complex concepts."
"The goal for the teacher is to construct a simple SAMR ladder that is coupled to Bloom’s Revised Taxonomy -- i.e., as the task moves from lower to upper levels of the taxonomy, it also moves from lower to upper levels of SAMR. The two Enhancement levels of SAMR (Substitution, Augmentation) are associated with the three lower levels of Bloom (Remember, Understand, Apply), while the two Transformation levels of SAMR (Modification, Redefinition) are associated with the upper levels of Bloom (Analyze, Evaluate, Create). In turn, within each grouping a similar ordering occurs -- e.g., Remember-type tasks are primarily associated with S-level uses of the technology, Understand-type tasks are associated with either S- or A-level uses of the technology, and so on."
