Abstract :

Critical thinking is one of the skills needed in the 21st century. Critical thinking skills are very important for students to have because with critical thinking skills, students can solve various problems. This study aims to describe students’ critical thinking skills in solving problems related to ratios. This study is a descriptive study with a qualitative approach. The data collection techniques used in this study were tests and questionnaires. This study involved 30 students in class VII-E at SMPN 1 Panti Jember. Data analysis techniques were carried out by reducing data, presenting data, and drawing conclusions. The data validity technique used triangulation methods. The test used in this study consisted of three questions. The results showed that the critical thinking skills of students were predominantly in the medium and low category.  Many students in class VIIE have high, medium, and low critical thinking skills, with 10, 12, and 8 students, respectively. Students with high critical thinking skills meet the criteria of focus, reason (R₁ and R₃), inference, clarity, situation, and overview. However, they still fall short on the criterion of reason (R₂). Students with moderate critical thinking skills meet the criteria of focus, reason, situation, and clarity, but fall short on the criteria of reason (R₂), clarity, inference, and overview. Students with low critical thinking skills meet criteria of focus, but still fall short on the criteria of reason, inference, situation, clarity, overview and therefore need improvement in all areas. Based on the results of this study, it is recommended that learning methods, approaches, or models that can accustom students to critical thinking be implemented, or that learning tools that can improve critical thinking skills be applied.
