“…Learning gains associated with peer-learning models have been reported at all educational levels, including elementary (e.g., Slavin 1990), secondary (e.g., Gillies 2008Gillies , 2003, college (Fraser et al 1977) and university contexts (e.g., Brown and McIlroy 2011;Postholm 2008;Payne et al 2006). Additionally, positive outcomes have been demonstrated in a variety of domains, for example, physical sciences (e.g., Topping et al 2011;Balfakih 2003;Chang and Lederman 1994) math (e.g., Sherman andThomas 1986), nursing (e.g., Chapman 2005), healthcare (Brown andMcIlroy 2011) andbusiness (e.g., Nordberg 2008). Apart from demonstrated cognitive gains among learners, peer instruction models often have the added benefit of enhancing learning for the peer tutors (Topping 2005;Goldschmid and Goldschmid 1976).…”
