In an attempt to theorize pedagogical interaction using conversation analysis, Waring (2016) argues that there are three main principles that revolve around what teachers do in classrooms. These three principles are competence, complexity, and contingency. The principle of competence includes teachers’ sensitivity to competency concerns of students in interaction, while complexity is about the ways teachers manage to accomplish multiple actions by producing a single turn. The principle of contingency, on the other hand, is concerned with the idea that teaching requires being responsive to the moment. This principle goes in line with the findings of aforementioned studies (Seedhouse, 2004; Walsh, 2011; Sert, 2015) in that the responsive behaviours of teachers should converge with the pedagogical goal of the moment, closely tied to the skills teachers show in online (Walsh, 2011) interactive decision making (Walsh, 2011; Li, 2017).
