The document discusses the SAMR model of technology integration. The SAMR model proposes four levels of technology use in education - substitution, augmentation, modification, and redefinition. At the substitution level, technology acts as a direct substitute with no functional change. Higher levels involve using technology to significantly redesign tasks and create new tasks previously inconceivable. Examples are given such as using a word processor instead of pen and paper (substitution), online research tools allowing for more in-depth exploration than print resources (augmentation), using comments and annotations features for collaborative work (modification), and real-time collaborative documents and projects (redefinition).
