Computing education research (CER) has gradually built its own identity as a research field. A part of this process has been the publication of a growing number of meta-studies which have explored the CER literature to identify the state of the art and trends in terms of active research topics, the nature of publications, use of different research methods, and the use and development of theoretical frameworks in papers published in different conferences and journals. In this chapter, we explore these meta-studies to build a picture of the way in which research in the field has developed. We identify trends over years, and discuss the implications of these findings for the future of the field.
