Abstract A meta-analysis method was used to analyze the experimental results of 25 constructive teaching studies quantitatively and systematically on the theme of “chemical bonds” at home and abroad. The results showed that compared with traditional teaching, the overall effect of constructive teaching in promoting the understanding of the concept of “chemical bonds” was significant. Class capacity, teaching time and geographical location had a significant positive impact on the effect of “chemical bonds” constructive teaching, and the more obvious the teaching effect of “chemical bonds” in small and medium-sized classes that had been using constructive teaching for a long time. Based on this, three suggestions for promoting the understanding of “chemical bonds” in teaching and research were proposed.
