“…Indeed, turn allocation and student selection can be seen as part of teachers' 'stocks of interactional knowledge' (PERÄKYLÄ; VEHVILÄINEN, 2003) and constitute one of the number of tasks that teachers, as the ones expected "to ensure that the discussion proceeds in an orderly manner" (NAS-SAJI; WELLS, 2000, p. 378), must coordinate during whole-group conversational activities. Such tasks include monitoring students' knowledge by, e.g., designing questions in ways as to elicit specific responses on notions that they are expected to have already learned (e.g., MARGUTTI, 2006), encouraging students' participation (e.g., SAHLSTRÖM, 1999), displaying affiliation with the students' contributions (e.g., TADIC; BOX, 2019; HALL; MALABARBA; KIMURA, 2019), and fostering students' agency (e.g., WILLEMSEN et al, 2019;PETERMANN;JUNG, 2017). For example, in their study of a fourth-grade classroom in the Netherlands, Willemsen et al (2019) showed how teachers dealt with students' questions and comments during whole-group conversation by returning the floor over to the students instead of responding to the questions themselves.…”
