“…Organizing classrooms around argumentation encourages students to interact directly with each other, as opposed to directing conversation exclusively to the teacher, who, in turn, evaluates comments (Berland, 2011;Duschl & Osborne, 2002;Martin & Hand, 2009). Making argumentation structures visible to students encourages them to make their ideas explicit, promoting the elaboration, connection, and consolidation of scientific understandings (Bell & Linn, 2000;Chin & Osborne, 2010;de Lima Tavares, Jiménez-Aleixandre, & Mortimer, 2010;Keys, Hand, Prain, & Collins, 1999;von Aufschnaiter et al, 2008). Some studies have shown that, over time, students appear to use more of the desired components and scientific norms in their argumentation (McNeill et al, 2006;Osborne et al, 2004;Sampson, Enderle, Grooms, & Witte, 2013).…”
