Successfully leading and guiding student discussions requires a range of fairly sophisticated communication skills. At the same time teachers are monitoring what’s being said about the content, they must keep track of the discussion itself. Is it on topic? How many students want to speak? Who’s already spoken and wants to speak again? How many aren’t listening? Is it time to move to a different topic? What’s the thinking behind that student question? How might the discussion be wrapped up? Most of us are not trained discussion facilitators. Here is an empirically developed instrument that can be used to more clearly identify the various skills involved in effective discussion facilitation and to gather student feedback that can help you assess yours.
