IMPLEMENTATION OF PROJECT-BASED LEARNING MODEL ON ACID-BASE MATERIAL TO IMPROVE LEARNING OUTCOMES AND ACTIVITIES STUDENTS SMAN 2 PERCUT SEI TUAN

Abstract

This research investigates the differences in learning outcomes and student activities between the Project-Based Learning (PBL) model and the conventional teaching model on acid-base material at SMAN 2 Percut Sei Tuan. Two classes from the XI grade were selected as samples: one experimental class using the PBL model and one control class using traditional lecture and discussion methods. Data analysis involved tests for normality, homogeneity, hypotheses, and correlations. The Independent Sample T-test results indicated a significant difference in both learning outcomes and student activities, with a significance value of 0.00 (𝑝 < 0.05), supporting the acceptance of Ha and the rejection of H0. Furthermore, the correlation test revealed a significant relationship between learning outcomes and student activities in the PjBL context, with a Sig. (2-tailed) value of 0.000 (𝑝 < 0.005). These findings highlight the efficacy of the PjBL model in enhancing student engagement and academic performance in learning acid-base concepts.
