“…Pupils often are inclined to ask the teacher for help, since they view the teachers as more able to facilitate learning as compared to their peers (Newman & Schwager, 1993). This is unfortunate since educational research has demonstrated that interactions between peers can augment their learning gains (e.g., Chinn, O'Donnell, & Jinks, 2000;Gillies & Ashman, 2000;Webb & Mastergeorge, 2003). Thus, there is increased interest in the mechanisms that bring about effective peer interactions, that is, the constituents of peer interactions that are related to higher learning gains, the context factors that affect peer interactions, and the relation of peer interactions with learning gains (e.g., Fuchs, Fuchs, Kazdan, & Allen, 1999;Gillies, 2004).…”
