Abstract:
This meta-analysis reviewed the literature on the e?cacy of game-based learning in English as a second language vocabulary acquisition. A systematic search of the literature produced 19 studies that met inclusion criteria. Using Bayesian methods and 20 standardized-mean-di?erence e?ect sizes we assessed 1) overall mean e?ects and between-studies variability, 2) subgroup analyses (grade level, sex, hardware, game type, intervention length, Foreign Services Institute level, allocation, and publication type), and 3) risk of publication bias. The overall e?ect was moderately large, indicating favorability to the video-game based learning groups. We found evidence of e?ect-size heterogeneity with a large between-studies standard deviation, along with large Q and I2 values. Subgroup analyses produced mixed results when partially explaining effect-size variability. Furthermore, all publication bias tests indicated a low risk of publication bias. We found that video-game based learning can make a significant di?erence in promoting English vocabulary acquisition and that integrating entertainment video games into educational contexts can result in substantial student learning gains.
