Instagram-Based Element Chemistry Poker Card Game in Improving Students' Critical Thinking

\nLearning media in chemistry subjects is needed so that students can better understand chemical materials that are very complex. Instagram-based Poker Chemistry Card game media as an alternative media in learning elemental chemistry. Critical thinking is a whole series of cognitive activities that are used by individuals in dealing with problems. This study aims to analyze the effect of applying the Instagram-based poker Chemistry Elements card game to increasing students' critical thinking. This media development research uses a quasi-experimental research method with a non-equivalent Pretest-Posttest Control Group Design type. This research was tested in class XI SMA using two classes with a total of 70 students. The test instrument was developed based on critical thinking indicators with a total of 10 questions.

The test data results were analyzed using a single ANCOVA with pretest as a covariate. The test results show that Ho is rejected which means there is a significant difference and influence in the application of Instagram-based chemical element poker cards on students' critical thinking abilities in elemental chemistry material. The results of this research confirm that Instagram-based elemental chemistry poker card media can improve students' critical thinking skills in elemental chemistry material.\n
