In order to investigate the effects of the mobile-game-based collaborative prewriting approach on individual writings and the research design of improving students’ writing performance, this research reviewed the published paper conducted by Wang and Song (2022), and proposed self - reflections from the perspectives of strengths, limitations, suggestions for improvements and applications. The research caught the popular topic, and the research design was also controlled with the arrangement of variables. There are still some limitations from the aspects of gender differences, the selection of mobile games, and the consistency of the design of the research questions. Suggestions for improvement are raised according to the limitations including gender, educational apps, and the research question.
