The document discusses the SAMR model, a framework for categorizing technology integration in education. It describes the four levels of the SAMR model: Substitution, Augmentation, Modification, and Redefinition. Substitution and Augmentation involve using technology to enhance lessons, while Modification and Redefinition transform lessons. Examples are provided for each level to illustrate how technology can be integrated at different degrees, from direct replacements to novel experiences not possible without technology.
