Abstract

This study aims to improve the critical thinking skills of fifth-grade students in science learning on light through the application of the Project Based Learning model assisted by a light experiment kit. This study uses the Classroom Action Research (CAR) method of the Kemmis and McTaggart model which is implemented in two cycles. The subjects of this study were fifth-grade students of SDN 3 Nagrikaler, Purwakarta Regency. The research instruments used included critical thinking skills tests, observation sheets of teacher and student activities, and documentation. Data collection techniques were carried out through tests, observations, and documentation, while data analysis used quantitative and qualitative descriptive analysis. The results of the study indicate that the application of the Project Based Learning model assisted by a light experiment kit can improve students' critical thinking skills. Classical completeness increased from 0% in the pre-cycle with an average value of 38.9 to 57.58% in cycle I with an average of 69.01, and increased again in cycle II to 93% with an average of 88.04. Teacher activity increased from 72.5% to 90.8%, while student activity increased from 65% to 86.6%. Thus, the application of the Project Based Learning model assisted by a light experiment kit is effective in improving students' critical thinking skills in science learning on light material.
