This research is based on the level of mathematical reasoning ability and Self confidence which is owned by Students who are still relatively low. then the purpose of this study are: 1) to know the level of students' reasoning ability seen from the achievement of minimum mastery criteria (KKM); 2) to know the students' perceptions of each indicator of mathematical reasoning ability; 3) to know the level of Self confidence categories of students on each item statement. This research uses qualitative approach with explorative descriptive method. Subjects in this study were students of class XI IPS1 which amounted to 20 students in SMA Putra Juang academic year 2017/2018. The research instrument consisted of test question instrument, non test instrument in the form of questionnaire, and interview guide. From the research, it is found that the reasoning ability and self confidence of XI IPS1 SMA Putra Juang class students on the opportunity material are included in low category. This can be seen from the test results where the value of Students 75% below KKM and only 25% above KKM.Serta from the questionnaire that shows the ability of self-confidence mathematics owned 50% low students, 25% Medium, 20% High, and 5 % very high. whereas students 'misconception in reasoning ability occurs in many indicators of students' ability to construct and test a conjecture in mathematics lessons, where only 5 students reach this indicator of ability.

Mathematical critical thinking ability is the ability of the thinking process to systematically investigate the thinking process itself, analyze arguments and bring up ideas with evidence on each meaning to develop a logical mindset that emphasizes making decisions about what to believe or do. The importance of mathematical critical thinking skills is to help students to think rationally in making decisions and conclusions to choose the best alternative and to be able to look at various problems. In addition to mathematical thinking skills, one of the affective aspects is self-confidence or self confidence. Self-confidence is self-confidence in the ability that it has so that it is sure to be able to solve a problem. This study aims to determine the difficulties of students in working on two linear variables in terms of student self-confidence and whether there is a relationship between self-confidence and mathematical critical thinking skills. The research method used is descriptive qualitative. The population of this study was all Mts in the city of Cimahi while the sample was the students of class IX B MTSN Kota cimahi. The critical thinking ability test instruments given were 5 questions accompanied by interviews with each student. and the Self Confidence questionnaire consisting of 20 positive and negative statements. Then the results obtained are the level of mathematical critical thinking ability of the students of the City of Cimahi, which is low and there is no influence between Self Confidence and mathematical critical thinking skills.

Mathematical reflective thinking ability is a process of thinking someone in understanding, identifying, analyzing problems based on relevant information and determining solutions to solve these problems. The importance of reflective marriage is to help students develop high-level thinking skills through their encouragement to: 1) connect new knowledge to their previous understanding. 2) thinking in abstract and concrete terminology. 3) apply specific strategies for new tasks. 4) understand their own thinking processes and learn on their own. The research method used is descriptive qualitative. The population of this study was all junior high school students in the city of Cimahi, which became the sample of this study were students of class VII-H at Cimahi Middle School 8. The instruments of reflective thinking ability were given to students as many as 5 questions for written tests accompanied by interviews with each student. Then the results obtained are the level of mathematical reflective thinking ability of junior high school students in Cimahi City based on written tests and the results of interviews with Cimahi students are still relatively low and there is no influence between student self-independence and mathematical relative thinking skills.
