“…Research on teacher development motivates attention to teacher noticing in preparation of mathematics teachers (e.g., Goldsmith & Seago, 2011;Jacobs, Lamb, & Philipp, 2010;Jacobs, Lamb, Philipp, & Schappelle, 2011;Mason, 2002;Sherin & van Es, 2009;Star & Strickland, 2008; van Es & Sherin, 2002) and science teachers (e.g., Barnhart & van Es, 2015;Luna, 2018;Luna, Selmer, & Rye, 2018). Teachers who notice student thinking, that is, identify and make sense of students' mathematical and scientific ideas and build on these ideas appropriately while making pedagogical decisions, are positioned to support reformoriented, student-centered mathematics and science instruction.…”
