Computing Education Research (CER) is a branch of Discipline Based Education Research (DBER) and is a relatively young research area. The Uppsala Computing Education Research Group (UpCERG) can be an example of how this area has evolved from the mid-90s, when the group was started, until today, when CER is an established research area at Uppsala University with a research program and full professors. This case study involves searching for and building a community, formulating frameworks for conducting CER, finding and including methods, theories, and people from other disciplines, and developing relevant research questions for CER. The people in UpCERG represent a wide area of research interests, and the case study illustrates, to a large extent, the development of CER in general. The chapter will relate the UpCERG evolution to the CER field in general.
