<![CDATA[ABSTRACT This study aims to determine the effect of the problem-based learning model on cognitive learning outcomes at SD Negeri Gayamsari 02 Semarang. This type of research is experimental research with the form of Pre-Experimental Design and Group Pretest-Posttest design. 29 class IVA students were involved as a population. The sampling technique was 29 students. The data in this study were obtained from assistance, tests, and documentation. The results showed that the average pretest was 58.6, while the post-test score was 80.68. Based on research that has been carried out in class IVA SD Negeri Gayamsari 02, the data obtained from calculations using the Paired Sample T-Test test obtained count> t table = 24.6179 > 2.045, then H0 is rejected and Ha is accepted, meaning that there is influence from the Problem-Based Learning learning model Against Science Learning Outcomes Class 4 SD Negeri Gayamsari 02.
