“…Researchers might ask questions related to the two important differences between this study and Frey and Kaise’s (2011) study, which were the dosage of play expansions received by target children (i.e., children in this study received fewer play expansions) and the implementers (i.e., teachers versus researchers). Furthermore, previous research has shown systematic prompting is related to increases in child play complexity (Barton, 2015; Barton, Choi, & Mauldin, 2019; Barton, Gossett, et al, 2019; Barton, Murray, et al, 2019), which should be considered when planning play interventions.…”
