Abstract: Compared with the method of traditional subjective literature review, meta-analysis is more objective, normative, and can effectively sort out general conclusion from existing empirical researches. Therefore, it has become an important method to identify the “best evidence” in the process of evidence-based educational reform. So far there are few educational studies in China using the meta-analysis method to review the empirical literatures. In view of this, this research analyzes the impact of STEM education on students’ academic achievement as an example of how to use meta-analysis to synthesise existing empirical research. We found: 1) STEM education is conductive to students academic achievements (d=0.410); 2) factors like educational methods, students’ educational stage, location and sample size can affect the effects. The study provides the general evidence of effects of STEM education and explores how to obtain reliable evidence through a literature review to support educational reform.

Key words: evidence-based educational reform, STEM education, academic achievement, meta-analysis
