The paper analyzes an array of scientific publications on continuing education over the past 45 years using the method of bibliometric mapping. We consider as units of analysis both (1) the collaborations of authors, organizations, and countries participating in scientific research on continuing education, as well as (2) keywords as indicators of thematic areas in the stream of publications on continuing education. We characterize the scientometric indicators of scientific directions in research on continuing education. Our analysis shows the high positive dynamics of publication productivity and the dominance of two main scientific areas in continuing education research: medicine (healthcare) and education itself. Our analysis also reveals a weak transcollaborative connection between (1) the authors of scientific research on continuing education and (2) the formation of groups of authors for conducting single studies. We further notice an expansion of the terminological (and, as a consequence, problemological) content of studies on continuing education towards interdisciplinary communication and the use of information technologies.
