This article argues the importance of including significant technologies-in-use as key qualitative research participants when studying today's digitally enhanced learning environments. We gather a set of eight heuristics to assist qualitative researchers in "interviewing" technologies-in-use (or other relevant objects), drawing on concrete examples from our own qualitative research projects. Our discussion is informed by Actor-Network Theory and hermeneutic phenomenology, as well as by the literatures of techno-science, media ecology, and the philosophy of technology.
