Multilateral activity model: improving children's gross motor

Introduction: Gross motor development of children is very important for their physical and cognitive growth. However, many children face difficulties in this regard. Multilateral activity models involving various body movements can be effective in stimulating and improving gross motor skills in early childhood. Objective: This study aims to determine whether multilateral activity models can improve children's gross motor skills. The instrument used is the Basic Motor Test with movement guidance to measure its impact, with a pre-experimental group pre-test-post-test research strategy and using the Gross Motor Skill test. Results: The normality test with Kolmogorov-Smirnov showed a Sig. value of 0.00 for the pretest and posttest of multilateral activity, which means that the data is not normally distributed because the significance value is less than 0.05 (0.00 < 0.05). The Wilcoxon test showed a positive increase from pretest to posttest, with an average increase in rating of 17.00 and a total rating of 561.00 from 33 respondents. There were five respondents who had exactly the same value. The results of the Wilcoxon test showed a Sig. value of 0.00, which is less than 0.05, so the hypothesis is accepted. This evidence confirms that multilateral activity has a significant effect on increasing children's gross motor skills. In addition, the determination test showed an R-square value of 0.977, which means that 97.7% of children's gross motor skills can be explained by the influence of multilateral activity. Conclusion: So it can be concluded that the multilateral activity outcome variable has a significant influence on the gross motor outcome variable.
