<![CDATA[It is important to develop problem-solving abilities in early childhood because in everyday life children will be faced with various problems that must be resolved. Teachers must create a conducive and more creative environment to motivate children to solve problems. This research aims to determine whether there is an influence of the differentiation learning model on the problem-solving abilities of children aged 5-6 years. The research approach used is a quantitative approach with a quasi-experimental design type of research and designing experiments that include an experimental group and a control group. Data collection techniques include tests, observation, and documentation. The data analysis technique used consisted of prerequisite tests and an Independent Sample t-test with a population of 41 children. From the results of the analysis of the Independent Sample T-test, it can be proven that the results of the research hypothesis that has been formulated are that there is a difference in the average problem-solving abilities of children aged 5-6 years because Ho is rejected and Ha is accepted, that is, there is the influence of the differentiation learning model. about the problem-solving abilities of children aged 5-6 years. Researchers propose that instructors who are interested in applying a diversified learning strategy construct a variety of activities to better assess learning and potential based on the research that has been conducted. The inclinations of every student are based on their unique abilities and interests. It is advised that future researchers wishing to perform comparable studies choose tasks that are more suited for monitoring youngsters between the ages of five and six to study their problem-solving skills.
