Application of Moodle-based Blended Learning to Improve Students' Critical Thinking Skills in Straight Motion Materials

The learning applied to the revised 2013 edition of the curriculum requires students to master critical thinking skills. One of the efforts to improve critical thinking skills is by applying blended learning. This study aimed to determine the improvement of critical thinking skills using Moodle-based blended learning. This type of research is a quasi-experiment with a nonequivalent research design. Sampling was done using purposive sampling technique, in order to obtain class X MIPA 4 as the experimental class and X MIPA 5 as the control class at Cisolok, which consists of 60 people, 37 are female and 23 are male. This research instrument uses essay questions to test critical thinking skills in straight-motion material with as many as 10 questions. The results showed an increase in critical thinking skills of experimental class students who obtained an N-gain of 0.60, while an increase in critical thinking skills of control class students obtained an N-gain of 0.56. The results of the hypothetical analysis of t-test using blended learning obtained t count pretest of 1.07 and posttest of 1.53, while t table of -2.048 so that t count > t table and H0 is rejected while Ha is accepted. Thus, it can be concluded that there is an increase in students’ critical thinking skills by applying Moodle-based blended learning on straight motion.
