“…Regarding the impact of intervention, and intervention studies focusing on the interpretation strategies of preservice mathematics teachers, it was consistently found that these strategies could be improved. Moreover, regarding the types of intervention used (Stahnke, Schueler, & Roesken-Winter, 2016), studies exploring professional noticing relied either on students' written work (Jakobsen, Ribeiro, & Mellone, 2014), observational videos (Kersting, 2008;Norton, McCloskey, & Hudson, 2011;König, Blömeke, Klein, Suhl, Busse, & Kaiser, 2014;Knievel, Lindmeier, Heinze, 2015;Osmanoglu, Isiksal, & Koc, 2015;Schäfer & Seidel, 2015), or both (Kilic, 2018).
