摘要:The focus of this article is to determine the influence of BrainGym on mathematical achievement of children. The main purpose of this research is to optimize brain activity to better mark the changes in mathematical achievement. The research used a pre test – post test control group design. In the intervention program, the treatment group was given exercises such as training the owl, cross crawl, sit up, and cross-legged kick for as long as 30 minutes. Whereas the control group was not given any exercises. Training was given 3 times per week for as long as 8 weeks. Data analysis conducted found that there is a significant difference in the treatment group between pre test–post test while there is no significant difference in the control group pre test–post test results. Therefore, it can be concluded that brain exercises does influence mathematical achievements.
