The Relationship on Critical Thinking Ability With the Self Confidence of Class Ix Materials of Builfding Side Rooms

Mathematical thinking ability is the ability of thinking processes to think systematically, analyze arguments and come up with ideas with evidence to develop a logical mindset on what to do. This very important because students will be helped in thinking mathematically rationally in drawing conclusions and observing the problems that exist. It is also necessary to pay attention to self confidence which is the ability of students to solve existing problems. This study aims to determine the relationship between students 'mathematical critical thinking and students' self-confidence in learning mathematics for Grade IX students. This study uses quantitative research with a non-experimental approach, namely the correlation approach. The population of this study is class IX at SMP Al Madani with a sample of 21 people through the sampling technique, namely convenience sampling. Data collection techniques using observation, questionnaires, and tests. Data analysis used normality test and Pearson correlation test. Based on the research, the results obtained were 1) normality test with a significance of 0.586> 0.05, which means the data was normally distributed and 2) a correlation value of 0.520 and significant 0.016
