Twenty-Two Years of ACE

This paper presents a bibliometric analysis of the first 22 years of the Australasian Computing Education Conference. A similar analysis was carried out after the first ten years; the purpose of this second instance is to explore what has happened since then. The report finds that ACE continues to be dominated by papers set in the context of programming courses and by papers that discuss various approaches to teaching and learning. The previous analysis identified an increase in papers that could be unequivocally described as research, as opposed to the experience reports that dominated the conference's first few years. This analysis finds that the increase has stopped and the balance now appears reasonably stable, with research papers somewhat dominant over other papers. An analysis of the authorship of ACE papers finds, among other things, that ACE shows a reasonable fit with Lotka's law of author productivity, but with a relatively high power constant, suggesting that the community might benefit from more authors contributing to higher numbers of papers.
