It's another of those phrases frequently used and almost universally endorsed but not much talked about in terms of implementation. What does facilitating discussion mean? How should a teacher do it? Two faculty researchers, Finn and Schrodt (2016), frame the problem this way: “The literature is replete with descriptive accounts and anecdotal evidence but lacks the kinds of empirical investigations that could create theoretical coherency in this body of work” (p. 446). They decided our understanding of discussion facilitation could be deepened with an operational definition, one that resides in an instrument to measure it quantitatively.
