While SAMR is often visualized as a ladder or staircase, this can be misleading because Substitution (the bottom of the ladder) is sometimes the best choice for a particular lesson. This is why it’s better to think of the SAMR model more as a spectrum. On one end technology is used as a one-to-one replacement for traditional tools, and on the other end technology enables experiences that were previously impossible without it.
SAMR is closely linked with Bloom's Taxonomy, a hierarchical ordering of cognitive skills that can help teachers and students learn.
The Six Levels of Bloom are - Knowledge (or Remember), Comprehend (or Understand), Application, Analyze, Synthesize (or Evaluate), CREATE.
It is the final stage of Create that Chromebooks can be most productive.

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.
