In response to the long-term challenges of skills shortages and mismatches, many countries worldwide have made significant investments in STEM education. However, to obtain a comprehensive understanding of the progress of global research on the implementation of STEM education, it is essential to compile case studies on STEM education. Therefore, we conducted a bibliometric analysis of 750 publications from Scopus database to assess the bibliographic content of case studies on STEM education from 2006 to 2022. Our main findings show that the first case study on STEM education dates back to 2006, and research in this direction has grown enormously and continuously over the last five years (counting for 72.9%). The most influential articles in the field are cited mainly in the background citations section and help provide an initial perspective for readers to understand the insights discussed later in the study. The most popular journals publishing case studies in STEM education are of good quality, ranking highly in Scopus and Web of Science categories. The analysis results show three main research directions: STEM education in higher education, STEM education expands to STEAM, and STEM education activities in K12-education.

This study makes use of recent evidence from developing countries by which to evaluate the effectiveness of private higher education institutions (HEIs), comparing them with public HEIs. In this way, it contributes to the literature by providing the first evaluation of productivity and its components in Vietnamese HEIs. The study uses the Färe-Primont index together with a meta-frontier approach. The research results indicate that the higher education system in Vietnam is powerfully driven by the large-scale public sector coupled with the long-term plans of Vietnamese state HEIs. Public HEIs have also been a major contributor to domestic research, and although there has been an increase in total factor productivity (TFP) throughout the research period, the private sector’s TFP was 30% higher than that of the public sector. Moreover, the higher technology gap rate (TGR) of private HEIs shows the potential for greater development in the future.
