Advantages and Challenges of STEM Education in K-12: Systematic Review and Research Synthesis

This study presents a systematic review of the literature on STEM education. We investigated the trends of STEM education, as well as its main advantages and challenges in K-12 settings. A total of 118 empirical studies published between 2013 and 2021 in refereed journals were included in the analysis. The findings indicate a steady increase in the number of STEM studies over the past nine years. The dominant discipline on the studies is science, while the most common level of education is upper secondary education. Most STEM interventions take place in formal settings and uses mixed research methods. The most popular educational material is simple tools, and the most measured variable is learner achievement. The most reported advantage is that STEM education helps develop of 21st century skills. On the other hand, the most reported challenge is that STEM activities are difficult to design. Further, the study discusses other advantages and challenges in detail, to map the opportunities and difficulties for students, teachers, and researchers. Finally, the study highlights some research gaps, as well as some suggestions for future research.
