Technology is not usually the deciding factor for successful or failed learning. However, technology in education has evolved into an important aspect of teaching and learning. Educational technology is supported by a broad and rich body of literature focused on research, theory, practice, and policy with authorship represented in more than 250 academic journals in the field (Perkins and Lowenthal 2016). Although the academic community has addressed teaching and learning from many angles, a few notable findings persist in the literature: prior learning, time-on-task, and formative feedback. This entry provides a discussion about each of these findings along with specific examples of the effective use of technology in education that promote them.
