Savanna Kingdom Exploration Workbook, Logical-Mathematical Competency

Abstract

This study aims to develop an Exploration Workbook themed “Savanna Kingdom” as a thematic learning medium to enhance early childhood logical-mathematical abilities. The method used is Research and Development (R&D) with a quantitative approach, including content validity testing using Aiken’s V formula and effectiveness analysis through gain scores and simple linear regression. The validation results show an increase in the average Aiken’s V score from 0.43 in the first round to 1.03 in the second, indicating that the instrument meets the criteria for high validity. Empirically, the use of the Exploration Workbook led to a significant improvement in children’s logical-mathematical scores across learning stages, with a gain score of 0.608 (medium category), and 52% of students showing high gains. The paired t-test revealed a statistically significant difference before and after the intervention. Furthermore, the simple linear regression analysis yielded an R² value of 0.863, meaning that 86.3% of the variation in children's logical-mathematical ability can be explained by the use of the workbook. These findings are supported by Vygotsky’s theory of the zone of proximal development and the constructivist theories of Piaget, Bruner, and Bloom, which emphasize the importance of active and progressive learning. It is recommended that teachers utilize thematic learning media and adopt holistic and adaptive approaches. Further studies are suggested to apply multiple regression models to explore other contributing variables that affect learning outcomes more comprehensively.
