ANALYSIS OF MATHEMATICAL CRITICAL THINKING SKILLS IN ARITHMETIC REVIEWED FROM SELF-EFFICACY

The ability to think critically mathematically is important for students to have in mathematics learning. But the reality is that some students still have low critical thinking skills. The purpose of this study is to describe the results of the analysis of the mathematical critical thinking ability of class X students, especially in the material of Arithmetic Rows and series reviewed from self-efficacy. The research method used is qualitative descriptive. The participants of this study are three students of class X at several high schools in North Sumatra. The instruments used were a description test on arithmetic line and series material with a total of three questions and a self-efficacy questionnaire with nine statements. Based on the results of the study, it was found that students with high, medium, and low levels of self-efficacy had critical thinking skills in the high category. Thus, descriptively there is no difference between the mathematical critical thinking ability reviewed from students' self-efficacy
