The importance of critical thinking skills in problem solving is one of the objectives of implementing learning. While the ability to analyze and summarize the information obtained is called reflective thinking. This study aims to describe how students' reflective thinking processes during problem solving. Subjects needed in this study amounted to 1 student selected from 30 students of class IX D SMP Negeri 5 Jember. The data was collected by using the method of tests, questionnaires and interviews with analytical techniques including data reduction, presentation and drawing conclusions. The results showed that the refractive thinking process of introverted students started from gathering information and interpreting it. Furthermore, students connect the existing information with the knowledge they have. The subject had no other alternative in solving the problem, so there was no reason for him to had a strategy that had been implemented. However, introverted students were able to find the right answers and checked the answers they received.

This study aims to describe the mathematical critical thinking skills of junior high school students after the implementation of educational videos in the learning process. Critical thinking skills involve a deep thinking process, where individuals not only accept information as it is but also question, evaluate, and assess the validity of the information. This ability allows someone to analyze information objectively, evaluate various arguments, and make decisions based on logical reasoning. This study uses a qualitative research type. The researcher will take 2 data sources based on the results of the pre-test of student abilities, namely 2 students with high thinking ability criteria and low thinking ability criteria. The results of the study showed that in critical thinking, high ability students met three main indicators, namely basic support (building basic skills), elementary clarification (giving simple explanations), and inference (concluding). While low ability students showed weaknesses in giving simple explanations (elementary clarification), they had good abilities in building basic skills (basic support) and concluding (inference). This shows that although R1 and R2 are able to use data and evidence effectively and draw logical conclusions, they have difficulty explaining concepts or information simply and clearly.
