“…The extant literature on teacher collaboration indicates that learning is fostered when teachers engage in conversations about new material (Davis, 2003), discuss strategies for effective teaching (Brownell, Yeagar, Rennels, & Riley, 1997;Little, 2003), push one another to experiment around new initiatives (Davis, 2003), work collaboratively to share expertise (Little, 2003;Smylie, 1995), and interpret policy messages (Coburn, 2001). Recent work by Goddard, Goddard, and Tschannen-Moran (2007) suggested that "the more teachers collaborate, the more they are able to converse knowledgably about theories, methods, and processes of teaching and learning, and thus improve their instruction" (p. 879).…”
