“…In this sense, many researchers suggest that teachers need to "learn to notice" in order to attend to student thinking, to develop better pedagogical decisions for increasing students' learning (Goldsmith & Seago, 2011;Jacobs, Lamb, & Philipp, 2010;Star & Strickland, 2008;van Es & Sherin, 2002). However, researchers argue that prospective teachers do not develop their noticing of student mathematical thinking naturally (Stockero, Rupnow, & Pasceo, 2017;Teuscher, Leatham, & Peterson, 2017), but they can learn it (PhelpsGregory & Spitzer, 2018;Stockero, 2014).…”
