In this paper, we analyze the approximately 60 publications concerned with women and/or gender from our much larger database of engineering education conference papers and journal articles. We focus on four regions that had at least two publications: North America, Australia, Europe, and the Middle East. In our review of these publications, we focus on geographic and disciplinary distribution of the researchers, topics and contexts represented, and the methods used. We found much overlap between regions, but also that certain topics, methods and contexts are more heavily represented in some regions than others. Regional variations as well as theoretical foundations are discussed here, and will be further analyzed in future work. Finally, we suggest that international research collaborations on gender would benefit from a theory-oriented model of collaboration.
