One of the most important developments in online education is closing the gap between content and engagement by making online learning content interactive. Instead of reading an article or watching a video and then engaging with it later in discussion or an assignment, apps allow for the interaction with learning content that is so important for understanding and retention. For instance, EdPuzzle and PlayPosit allow instructors to add questions, comments, and other interactions to videos. Genially is a recent addition to this movement. It allows instructors to easily add interactions to both live presentations and asynchronous online content and is rapidly gaining converts among educators.
