The Influence of the Problem-Based Learning Model Assisted by Electronic Student Worksheets on the Science Learning Outcomes

The problem of this research is the low natural science learning outcomes of elementary school students caused by student-centered learning and the inadequate use of teaching materials. This study aims to determine the effect of the problem-based learning model assisted by electronic student worksheets based on liveworksheet on natural science learning outcomes. This study uses a quantitative approach with a nonequivalent control group design. The research sample consists of fifth-grade students from SD Muhammadiyah 29 Sunggal. Data was collected through pretest and posttest, and analyzed using normality test, homogeneity test, and hypothesis test through Independent Samples t-test. The results show that the average posttest score of the experimental class was 86.08, higher than the control class at 76.33. The t-test resulted in a significant value of p < 0.001 with a mean difference of -9.747 and a 95% confidence interval (-14.095 to -5.398), indicating a significant difference. Based on the data analysis results, it is stated that the problem-based learning model assisted by electronic student worksheets has an impact on improving the learning outcomes of 5th-grade elementary school students in science learning. These findings support the development of student-centered science education aligned with the Merdeka Curriculum
