“…In fact, from a sociolinguistic perspective (Carlsen, 1991), educational research has stressed the instructional functions of classroom-based inquiry in science as a means for facilitating the construction of scientific knowledge (Solomon, 1994) and supporting children's abilities for scientific reasoning (e.g., May, Hammer, & Roy, 2006;Russ, et al, 2008). Following this, a growing body of research has developed an interest in classroom discourse (e.g., Abell, Anderson, & Chezem, 2000;Cazden, 2001;Edwards & Westgate 1994;Hogan, 1999;Kelly & Crawford, 1997;Lemke, 1990) for its relevance to children's inquiry (Hammer, 1995;van Zee, 2000;van Zee & Minstrell, 1997), for the development of student ideas in science (Mortimer, 1995), and for students' conceptual and cognitive development (Sprod, 1998).…”
