Influence of Project Based Learning Models and Learning Interest on Critical Thinking Skill Students of Class X SMAN 4 Wajo

Abstract

This study is a true experiment which employs 2x2 factorial design. The purpose of this study is to analyze the difference in critical thinking skills of students who are taught using the Project Based Learning model and those taught with the Discovery Learning model are reviewed as a whole and reviewed from those who have high and low interest in learning. The sample in this study is 61 students from classes taught using Project Based Learning, and 61 students taught using Discovery Learning. The hypothesis test was carried out with a two-track anava, showing the average score of critical thinking skills of students who were taught using the Project Based Learning model of 21.64 and those who were taught using the Discovery Learning model of 19.13. The difference in the average score of critical thinking skills of students who were taught using the Project Based Learning model and the Discovery Learning model for students who had high interest in learning was 24.82 and 21.35. Meanwhile, the average scores of critical thinking skills of students who were taught using the Project Based Learning model and those taught using the Discovery Learning model for students who had low interest in learning physics were 19.12 and 17.35. Based on the description of the hypothesis test, it can be concluded that there is a difference between the Project Based Learning model and the Discovery Learning model on students' critical thinking skills, there is a difference between the Project Based Learning model and the Discovery Learning model on the critical thinking skills of students with high interest in learning, there was a difference between the Project Based Learning model and the Discovery Learning model on the critical thinking skills of students with low learning interest, and there was no interaction between the learning model and learning interest on the critical thinking skills of students.
