Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) model on students’ IPAS learning outcomes in grade V at SD Negeri 091608 Sinaksak. The research sample consisted of 25 students with the topic of ecosystem harmony. The research instrument was 25 multiple-choice questions that had been tested for validity and reliability. Data were collected through pretest and posttest to measure students’ initial and final abilities. Data analysis was conducted using the normality test and paired sample t-test. The results of the hypothesis test showed a significant difference between pretest and posttest scores with a significance value (Sig. 2-tailed) of 0.000 < 0.05. In addition, there was an average increase in learning outcomes of 31.120. Therefore, it can be concluded that the Project Based Learning (PjBL) model h
