"Each of these protocols will have a “time required” section which is my [Dakin Burdick, Center for Teaching Excellence, Endicott College, 2011] best guess of how much time each will take. That estimated time is based on students having about a minute to respond individually to any issue. That limit was chosen on the assumption that the small group discussion is intended to prepare the students for the large group discussion. If the small group discussion is intended to develop meaningful outputs, the times will probably be longer.
It will also list an “Online equivalent” for the exercise. When selecting the tools you wish to use online, you will first have to decide whether an activity works best synchronously or asynchronously. In general, I tend to aim at asynchronous interaction first, because it allows participants around the world to log in at their convenience. I like the idea of global conversations, and they tend to be richer and more diverse. Asynchronous discussions also give participants more time to think about their about their responses, and give shy or contemplative participants a better chance to contribute. Asynchronous interactions take a long time though (several days at least), which may lead you to choose synchronous interactions instead. Synchronous interactions are quicker and because they often involve audio or video, they can more quickly establish a sense of community and a perceived rapport with the instructor."
