The Effectiveness of Physics Learning with Blended Learning Models using the Edmodo Application to Improve Students' Critical Thinking Skills

Abstract

This study aims to describe the effectiveness of learning physics with a blended learning model using the Edmodo application to improve the critical thinking skills of high school students. The sample of this study were students of SMA Negeri 1 Ngronggot which consisted of two classes, namely X MIPA 1 and X MIPA 2, each class totaling 30 students. This research is pre-experimental research with one group pretest-posttest design. Before learning is done, students are given an initial test (pre-test) and after learning, students are given a final test (post-test) with the same material. The collected data was then analyzed using paired t-test, n-gain calculation, and independent t-test. which were analyzed quantitatively. The results showed that there was an increase in students' critical thinking skills scores with an average value of n-gain on the high criteria in each experimental class and there was no difference in the average value of n-gain between the two experimental classes. It can be concluded that learning physics with a blended learning model using the Edmodo application can effectively improve students' critical thinking skills. This research implies that learning physics with a blended learning model using the Edmodo application can be used as an alternative learning model that can be used to improve students' critical thinking skills.
