Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) model on the learning outcomes of IPAS for fourth-grade students at SD Swasta Ra Kartini Cerdas Bangsa. The background of this study is based on the low IPAS learning outcomes caused by teacher-centered learning, limited use of learning media, and low student participation during the learning process. This study employed a quantitative approach using a quasi-experimental method with a One-Group Pretest–Posttest design. The research subjects consisted of 23 fourth-grade students at SD Swasta Ra Kartini Cerdas Bangsa. Data were collected through learning outcome tests in the form of pretests and posttests. The results showed that the average pretest score was 80.00, while the average posttest score increased to 90.52, indicating an improvement of 10.52 points. The normality test results indicated that both pretest and posttest data were normally distributed. Furthermore, the results of the paired samples t-test showed a t-value of –11.989 with a significance value of 0.000 < 0.05, which indicates a significant difference between students’ learning outcomes before and after the implementation of the Problem Based Learning model. Therefore, it can be concluded that the Problem Based Learning model has a positive and significant effect on IPAS learning outcomes of fourth-grade students at SD Swasta Ra Kartini Cerdas Bangsa.

Abstract

This study aims to improve student learning motivation through the implementation of the Project-Based Learning (PjBL) model in the IPAS subject for fourth-grade students at SDN 105330 Bangun Sari. The research design used in this study is Classroom Action Research (CAR). In detail, the stages in the action research design begin with planning, implementation of action, observation, and reflection in each cycle, continuing until the desired improvement is achieved. The approach used in this study is a qualitative approach. The subjects involved in the study are fourth-grade students at SDN 105330 Bangun Sari Baru, Tanjung Morawa District. The class consists of 32 students, including 9 boys and 23 girls. Based on the findings, it can be concluded that the application of the Project-Based Learning (PjBL) model can increase students' learning motivation in the IPAS subject. This is evidenced by the increase in student motivation questionnaire scores and learning test results during the learning process. Moreover, the implementation of PjBL also makes learning more meaningful and enjoyable for students, as well as actively engaging them in the learning process.
