The Effectiveness of the Outdoor Learning Activity (OLA) Model Based on Javanese Culture in Improving Children's Working Memory

Introduction: This research aims to determine the effectiveness of the Outdoor Learning Activity (OLA) model based on Javanese culture in improving children's working memory (WM) and to identify the differences in working memory achievements in each OLA activity implemented, including Kubro Siswo dance, Engklek, and fun cooking. Methods: The research used a Pre-test and Post-test Nonequivalent Control Group Design with 171 subjects from the control group, experimental group 1, and experimental group 2. Data collection was conducted using a working memory test, and the data analysis used was one-way ANOVA and N-Gain Score.Results: The N-Gain scores for Experimental Group 1 and Experimental Group 2 reached 77.29 and 80.50, respectively, greater than 76. The average working memory achievement in each OLA activity shows Engklek at 47.03, Kubro Siswo dance at 45.65, and Fun Cooking at 44.24. Conclusions: The research results show that the N-Gain score >76, indicating that the Javanese culture-based OLA model is effective in improving children's working memory. It is concluded that the Engklek treatment is the OLA treatment with the highest average working memory score, followed by the Kubro Siswo dance treatment and lastly the Fun Cooking treatment.
