Abstract
Purpose – This study aims to investigate the impact of the Project-Based Learning (PjBL) model on students' learning outcomes in the science subject (IPAS) based on Marharoan Bolon for Grade IV students at UPTD SD Negeri 122345 Pematangsiantar. The study is designed to assess the effect of this teaching model on student performance.
Methodology – A pre-experimental research design using the One-Group Pretest-Posttest Design was employed. The sample consisted of 26 fourth-grade students from UPTD SD Negeri 122345 Pematangsiantar. The study utilised various instrument tests, including validity, reliability, difficulty level, and discrimination index tests. Data were collected through tests and documentation. Data analysis involved normality testing, t-test, and N-Gain to determine the effect of the PjBL model on learning outcomes.
Findings – The study found a significant positive effect of the PjBL model on students' science learning outcomes, with a significance value of 0.00 (p < 0.05) and a t-value of 16.11, exceeding the critical t-value of 1.70. These results indicate that the PjBL model improves students’ academic performance in IPAS.
