Educational institutions increasingly rely on digital platforms to deliver content and learning, monitor attendance, communicate with stakeholders, and evaluate institutional performance. Despite the efficiency and accessibility gains they offer, digital platforms are powered by personal data which, through a process of datafication, can be used to track, monitor, and profile staff and students. The insights drawn from this data can be used to shape educational and professional futures. This article examines how datafication has become a social justice issue in education, (...) discussing the implications for well-being, decision-making, governance, and power in education. Using Hintz and colleagues framework for data justice, it applies and explores the three dimensions of data justice to the context of education, including: (1) infrastructures (2) regulation, and (3) informed and knowledgeable stakeholders. The paper discusses the unique challenges to achieving data justice in education and concludes by outlining the key questions for a future research agenda. (shrink)
