"The SAMR model is a useful tool for helping teachers think about their own tech use as they begin to make small shifts in the design and implementation of technology driven learning experiences to achieve the next level. Dr. Puentedura has included Questions and Transitions Ladders with the SAMR model to help teachers make transitions to each level. Teachers in the substitution and augmentation phase can use technology to accomplish traditional tasks, but the real learning gains result from engaging students in learning experiences that could not be accomplished without technology. At the Modification and Redefinition level, the task changes and extends the walls of the classroom."
