This study aims to analyze the influence of the use of quantum phenomenon learning media implemented in Think Pair Share (TPS) learning models on improving students critical thinking skills. This type of research is quasi-experimental research with research design nonequivalent control group design. The population of this research were all students of class XII of Senior High School Attohiriyah Bodak, Central Lombok, West Nusa Tenggara. The sample of this study was class XII-F as the experimental class and XII-E as the control class selected using Purposive Sampling techniques. Students critical thinking skills were analyzed using the Separated Variance t-test, obtained at 3.22 and at 1.67 at a significant level of 5%. Therefore, then Ho is rejected and Ha is accepted. So, it can be concluded that the learning media strong phenomenon has a positive effect on students critical thinking skills. The magnitude of the influence of Phenomenon Quantum learning media by increasing the critical thinking skills of students analyzed using N-gain was obtained 0.68 in the medium category for the experimental class and 0.23 in the low category for the control class.
