The impact of using LINE@ on the cooperative learning to improve the critical thinking skills of high school students

The widespread use of social media enables new opportunities in various fields including in education. This study aimed to determine the influence of social media usage, in this case, LINE@, on cooperative learning environment to improve critical thinking skill. This research was conducted on Year 11 students on physics, especially for Elasticity subject. The method used in this research was the quasi-experiment with pretest-posttest controlled group design. The independent variable of this research was learning strategy. The dependent variable was critical thinking skill measured by essay. The covariates used were prior knowledge measured by multiple-choice questions. Statistical analysis technique used ANCOVA with the error margin of 5%. The results showed that students who received cooperative learning using LINE@ tend to have better critical thinking skills after learning compared to conventionally taught students. Prior knowledge can be used as a predictor to examine the level of critical thinking skills. The contribution of previous knowledge was relatively small indicating that the role of learning strategy was relatively high in influencing the improvement of critical thinking skills.
