“…Both contributing and attending to discussion messages are important activities in realizing the theoretical potential of online discussions to support knowledge construction (Wise, Speer, Marbouti, & Hsiao, 2013). However a substantial research base shows that in actual asynchronous discussions learners often pay limited attention to others' posts (Hewitt, 2003;Thomas, 2002), resulting in conversation patterns that can be characterized as incoherent rather than dialogic (Herring, 1999;Webb, Jones, Barker, & van Schaik, 2004).
