Pengaruh Penerapan Model PjBL (Project Based Learning) terhadap Kemampuan Berpikir Kritis Peserta Didik (Kelas III Sekolah Dasar)

Abstract

This study aims to examine the application of Project Based Learning (PjBL) models to improve the critical thinking skills of elementary school students in learning fine arts on geometric shapes in buildings. This study was motivated by the low ability of students to connect geometric concepts with works of art due to conventional learning methods that are one-way. This study used the Kurt Lewin Classroom Action Research (CAR) method with 24 third-grade students as subjects at SDN Tanjungrejo 4, Malang City. Data collection techniques included observation, testing, and documentation. The study was conducted in two cycles with stages of planning, action/implementation, observation, and reflection. The results showed a significant increase in both the activity and critical thinking skills of students. The average critical thinking score increased from 59 (pre-action) to 70 (cycle I) and reached 82 (cycle II). This PjBL model has proven effective in creating an active, collaborative learning atmosphere and supporting the development of students' critical thinking skills. This research shows that the PjBL model is an appropriate alternative strategy in improving critical thinking skills of students at the elementary school level.
