This theoretical paper argues that Feminist Science and Technology Studies (FSTS) can help advance the emancipatory project in critical Ed Tech research. To support this claim, we deploy Tsing's concept of 'scale-making projects' (2005. "Friction: An Ethnography of Global Connection." Princeton, NJ: Princeton University Press) to connect 'global' narratives to 'local' users in a mobile learning project for Kenyan health workers. Drawing from this exemplar case, we discuss more broadly how FSTS provides useful theory and methods for tracing the trans-national power relations of digital technologies 'on the ground'. The paper concludes by advocating for new forms of emancipatory Ed Tech research -- ones framed not only within oppositional pairings such as 'global' versus 'local', but which elucidate how binaries themselves are constituted through far-flung trans-national arrays of sociomaterial practice.
