However, there is still a lack of studies that seek to visualize the evolution of scientific literature on the subject. This paper seeks to fill this gap through the development of a bibliometric analysis by carrying out a data search on the Web of Science™ database and subsequently transferring the acquired data for treatment to the VantagePoint © software package. The data indicate that research on PBL shows a strong progression since the end of the twentieth century, with a high volume of the most impact- ing studies being carried out by a group of researchers who are currently linked to or used to be connected to the Maastricht University. As a result of these studies, a geographical (from North America and Europe to Asia) and academic (from research in medical education to other biomed- ical and engineering areas) spread of scientific production regarding this teaching methodology has arisen.
