Taking publicly funded projects in STEM education as a special lens, we aimed to learn about research and trends in STEM education. We identified a total of 127 projects funded by the Institute of Education Sciences (IES) of the US Department of Education from 2003 to 2019. Both the number of funded projects in STEM education and their funding amounts were high, although there were considerable fluctuations over the years. The number of projects with multiple principal investigators increased over time. The project duration was typically in the range of 3–4 years, and the goals of these projects were mostly categorized as “development and innovation” or “efficacy and replication.” The majority of the 127 projects focused on individual STEM disciplines, especially mathematics. The findings, based on IES-funded projects, provided a glimpse of the research input and trends in STEM education in the USA, with possible implications for developing STEM education research in other education systems around the world.

STEM教育的研究和趋势：对公共资助项目的系统分析

我们以公共资助的STEM教育项目为特殊视角，旨在了解STEM教育的研究和趋势。我们确定了2003年至2019年间由美国教育部教育科学研究所（IES）资助的127个项目。尽管在STEM教育中有较大的波动，但STEM教育中的资助项目数量和金额都很高。这些年。随着时间的推移，拥有多个主要调查人员的项目数量有所增加。该项目的期限通常为3-4年，这些项目的目标主要归类为“发展与创新”或“效率与复制”。127个项目中的大多数集中于单个STEM学科，尤其是数学。这些结果基于IES资助的项目，
