The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases (e.g., ERIC, Springer Link, Taylor & Francis, Wiley Online Library Full Collection, and Scopus) to find chemical bonding-intervention studies. Thus, it included 50 chemical bonding-based intervention papers (15 dissertations, 32 articles, and 3 proceedings). The current "meta"-analysis found that the overall effect-size of chemical bonding-based intervention studies was 1.007, which shows a "large" effect. Findings regarding moderator analysis displayed non-significant differences between educational levels and a statistically significant difference between the intervention types. This "meta"-analysis reveals that the chemical bonding-based intervention studies are effective at improving the participants' academic performance in terms of chemical bonding. Further, it denotes that when the abstract nature of chemical bonding is overlapped with the features of the intervention type, the interventions (e.g., cooperative learning and enriched learning environment with different methods) result in better academic performance. Since this study, like all "meta"-analyses, points out consistent and inconsistent findings among published research, further "meta"-analysis studies should be undertaken to resolve any contradictory findings.
