“…Several observational studies also adopt a functional approach and have been instrumental in identifying data use practices such as grouping (including “triage” strategies for students on the cusp of proficiency as well as for differentiation; Breiter & Light, 2006; Brimijoin, Marquissee, & Tomlinson, 2003; Ebby, 2018; Nabors-Olah et al, 2010; Park & Datnow, 2017), reflective sense making and inquiry (Blanc et al, 2010; Braaten, Bradford, Barocas, & Kirchgasler, 2018; Garner & Horn, 2018; Riehl, Earle, Nagarajan, Schwitzman, & Vernikoff, 2018), predicting performance on other assessments (Young & Kim, 2010), adjusting curriculum content and pacing (Hamilton et al, 2009; Kerr, Marsh, Ikemoto, Darilek, & Barney, 2006; Nabors-Olah et al, 2010), selecting materials (Evans et al, 2018; Marsh et al, 2015), engaging students in data use (Kennedy & Datnow, 2011; Marsh, Farrell, & Bertrand, 2016), and identifying students for out-of-class support (Marsh et al, 2015; Supovitz & Morrison, 2011). Like survey research, each study has contributed to our knowledge of data use, while often focusing on a narrow or specific data use practice.…”
