“…Miller, Glover, Averis (2008) define the teacher noticing as the "ability to identify quickly and understand the elements of meaning in an environment" (p. 84); while Jacobs, Franke, Carpenter, Levi, & Battey (2007) point out that it concerns the answer that the teacher gives to what he or she perceives. Other researchers try to acknowledge either the kinds of features that teachers notice (Van Es & Sherin, 2008) or the ways to influence what teachers perceive (Miller et al, 2008;Santagata, Zannoni, & Stigler, 2007). Certainly, the question how teachers make sense of and react to the instructional settings (Santagata et al, 2007;Star & Strickland, 2007) is still valid.…”
