<![CDATA[This study aims to determine the influence of the Project Based Learning (PjBL) learning model using the STEAM approach on the learning outcomes of grade V students in building space materials at UPT SDN 231 Gresik. The background of this research is the low learning outcomes of students due to the monotonous learning process and lack of active student involvement. So that the STEAM-based PjBL learning model helps students in grade V UPT SDN 231 Gresik to be more active in learning, especially in the field of mathematics study of building space materials. This study uses a quantitative method with a quasi experiment design of the non-equivalent control group design. The research sample amounted to 30 VB students in the experimental class group and VA class students as the control class. The data collection technique uses learning outcome tests and student response questionnaires. The test results used were in the form of pretest and posttest questions which were carried out by analyzing data through normality, homogeneity, and T tests using SPSS 26. The test results using SPSS 26 showed that the value of the tailed sig-2 was 0.003 < 0.005. Thus, there is a significant influence of the application of the STEAM-based PjBL model on improving student learning outcomes. Therefore, the students' response to the application of this model is also very positive. Thus, the STEAM-based PjBL model can be an effective alternative learning model in improving the learning outcomes of students in class V UPT SDN 231 Gresik]]>
