IMPLEMENTASI PENDEKATAN PEMECAHAN MASALAH UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KREATIF DAN PENALARAN MATEMATIS SISWA SMP

Creative thinking skills and mathematical reasoning students need to be increased to achieve the goals of learning mathematics. But learning school mathematics teachers do during these generally lack the ability to develop. One way that can enhance creative thinking and reasoning skills by applying mathematical problem-solving approach. This study aims to determine the increase creative thinking skills and mathematical reasoning in students who learn to approach problem solving than students who studied with conventional methods. This study uses a quantitative approach to the type of experimental research. The population in this study were all students of class IX SMP Negeri 1 Peusangan Selatan which consists of three classes with 65 students the number of people. Sampling was done randomly from three available classes is taken two classes (a class IX-2 as experiments and a class IX-3 control class). Data collection instruments in the form of test creative thinking ability and mathematical reasoning, observation sheets, and the attitude scale questionnaire. Statistical testing using t-test to see the difference in the ability of students who previously tested for normality and homogeneity of the significant level of 0.05. The results showed that 1) the increase creative thinking skills students learn mathematical problem solving approach is better than the students who received learning with conventional methods, 2) based on the attitude scale questionnaire, students positive attitudes towards learning mathematics with problem solving approach. Mathematics learning using proven problem-solving approach can improve
