A Meta-analysis of selected studies on the effectiveness of gamification method for children. Multiple gamification methods are used to motivate students to improve their learning outcomes. Yet, this method is still very rarely used in learning for children aged 6-10 years. This systematic review and meta-analysis aim to objectively determine the effectiveness of gamification method in increasing knowledge, skills and attitudes of children aged 6-10 years.The data were obtained from the ERIC, Emerald and Elsevier databases published between 2014-2018 using the keywords of "gamification on education", "gamification methods", and "children". In the chosen systematical analysis, 6 studies were then reviewed using a meta-analysis. The effect summary showed a value of 1.01 with confident interval of 0.98-1.05, which indicates that gamification method is statistically effective in improving students' knowledge, skills, and children's attitudes. The Z test with a value of 0.68 and a significance level of 5% also showed a significant effect of this method calculated by random-effect models.
