The problem in this study was to determine whether there was a significant influence between the Problem Based Learning model on student learning outcomes in terms of changes in shape of objects, theme 7 sub-themes 1 learning 2. with a quantitative approach to the One Group Pretest-Postest Design research design. The population used is fifth grade students, amounting to 26 people. Data collection techniques and instruments: 1) Test. The research instrument is a test in the form of pre-test and post-test to measure learning outcomes. This research was conducted at SD Inpres Kuanino 3 Kupang City, the results of hypothesis testing, using a paired sample T-test obtained a t_count of 11.351, which means it is greater than the t_table of 1.711, showed that the significance value (2-tailed) was 0.001. This shows that at the significance level (2-tailed) <0.05. In accordance with the basis for making decisions in this test, if the sig.(2-tailed) <0.05, so there is a significant difference between learning outcomes in the pretest-posttest data. Based on the results of the research above, it can be concluded that there is an influence between the Problem Based Learning model on student learning outcomes in the matter of changes in shape of objects.
