In this module, learners are introduced to the interaction between teaching, content, and technology, using the acronym TPACK. Through this acronym, teachers are invited to recognize the ways in which different types of knowledge work together. We are also introduced to an additional acronym: SAMR. This acronym invites teachers to consider how essential the tool is to achieving learning outcomes, and whether it simply replaces an older type of technology, or if it transforms the learning process itself.
