<![CDATA[This study aims to analyze the effect of block play on the problem-solving abilities of early childhood students at RA Al-Ma'arif, Gorontalo City. Problem-solving ability is a fundamental aspect of cognitive development that should be nurtured from an early age, as it is closely related to logical thinking, creativity, and decision-making skills in everyday life. Block play was selected as the learning medium because it provides concrete, enjoyable, and interactive learning experiences while encouraging children to explore, observe, and develop solutions to various challenges. This research employed a quantitative approach using a one-group pretest-posttest design involving 30 children as research participants. Data were collected through observation and problem-solving ability tests and were analyzed using the t-test to determine the significance of the treatment effect. The findings revealed a significant improvement in children's problem-solving abilities after participating in block play activities. The mean pretest score increased from 55.4 to 82.7 in the posttest. Statistical analysis indicated that the calculated t value of 6.25 exceeded the critical t value of 2.06, demonstrating a statistically significant effect of block play on children's problem-solving abilities. Furthermore, the learning mastery level increased from 35% to 85%. These findings suggest that block play is an effective learning medium for enhancing logical thinking, creativity, and problem-solving skills among early childhood learners.]]>
