“…A growing subfield of education researchers are calling this the "datafication" of education, where every aspect of schooling, students, teachers, etc., is rendered as data to be collected, analyzed, surveilled, and controlled (Bradbury 2019;Bradbury & Guy-Holmes, 2018;Buchanan & McPherson, 2019;Selwyn, 2015;Williamson, 2017a). The "datafied teacher," in particular, faces increased pressures to rely on numerical data (e.g., standardized achievement tests, value-added model output) and evaluative tools (e.g., observation rubrics) to guide their pedagogical decisions and classroom practices (Holloway, 2019;Bradbury & Roberts-Holmes, 2017;Hardy, 2018). In these data environments, the "quality" of the teacher is narrowly defined by numbers, while "improvement" is defined as increasing these numbers, rather than improving practice and fostering collaboration (Perryman, 2009;Taubman, 2009).…”
