SAMR Model

Substitution

When students use a word processor without any features for editing, education technology is operating at the lowest level, as a substitute for pen and paper, with no functional improvement.

Augmentation

When that word processor has sophisticated editing functions to improve the final product, for example the possibility of printing out the document, students are working at the augmentation level, using it as a substitute with functional improvement

Modification

When tasks become something quite different for example the writing becomes part of a blog, wiki or social network exchange that is at the modification level.

Redefinition

When technology allows students to access new tasks, for example creating a video-documentary based on their writing. This final level is the most difficult to describe because the evolution is constantly redefining what becomes possible using technology that is the redefinition level.
