Discussions of ethics within in-service teacher education tend to focus on microethical concerns (e.g., discipline) that deal with decision making at interpersonal levels. Issues concerning educational technology are no exception. Yet, as teachers choose and are expected to integrate technological devices (e.g., laptops) and sociotechnical systems (e.g., learning management systems) into pedagogical practices, their classrooms and schools may become implicated in macroethical issues (e.g., electronic waste) that reach beyond the local consequences of their direct actions. Necessitated by tight couplings of (...) technology and education, this article presents the concept of macroethics for teacher educators by grounding it in three areas of concern: obsolescence, automation, and big data. These three areas offer opportunities to make economic and environmental issues more central to case studies on technology in teacher education. At the same time, teacher educators will need to put emphasis on critical reflection and collective action in units on macroethics since the limited impact of individual decision-making on these issues may put teachers in double binds (i.e., dilemmas with contradictory demands).
