"SAMR, a model designed to help educators
  integrate technology into teaching and learning, was developed by
  Dr. Ruben Puentedura, Ph.D.. The model aims to
  enable teachers to design, develop, and integrate digital
  learning experiences that utilize technology to transform
  learning experiences to lead to high levels of achievement for
  students."
