The pedagogy, andragogy, and heutagogy (PAH) continuum have been widely endorsed within higher education and online learning over the years. Thus, the evaluation of research productivity has become relevant due to the emerging development of the PAH continuum as a theoretical framework. This paper aims to explore the research productivity within the PAH continuum by performing a bibliometric performance analysis. An iterative search strategy was performed to identify PAH authors and then investigate their research productivity over a 5-year period (2017–2022) using the SciVal analytics instrument by Elsevier. Drawing upon the results from multiple bibliometric analyses, the study explores publication productivity specifically in relation to the PAH continuum. This study revealed that distance education, learning, teaching, professional development, and lifelong learning have been the most prominent research areas within the PAH continuum. Within that, related topics were identified, including online learning, mobile learning, e-learning, and educational technology.
