A burgeoning literature, policy landscape, and set of practice resources and guidelines have emerged around ethical educational technology development and implementation, particularly in the context of data or artificial intelligence informed tools. However, while these resources provide valuable tools to support navigation of the ethical landscape, they suffer from some limitations. These include a focus on coarse-grained, clear cut cases; a lack of attention to dilemmas and tensions; and a potential focus on procedural aspects of ethics, rather than our moment-to-moment ethics-in-action. This paper provides a case study description, using a reflective design case to provide a more textured micro-ethics. The case approach, its exemplification as a tool for micro-ethics, and the features of interest in our particular case each provide valuable tools for the educational technology community.
