Studi Kasus Analisis Kemampuan Disposisi Matematis pada Mata Pelajaran Matematika Kelas IX Sekolah Menengah Pertama

Abstract

This research aims to analyze more deeply the mathematical disposition abilities of students in learning mathematics. The method used in this research is a qualitative method. The subjects in this research were fifteen students in class 9 of 1 Sanden Junior High School. Of all the subjects, two students were taken for analysis, these two students had high and medium abilities. Data collection techniques in this research are non-test techniques, namely observation, questionnaires and interviews. With research instruments in the form of questionnaires and interview guidelines. The results of this research are based on the researcher's observations carried out on class 9D and it was found that students were less confident in presenting their answers in front of the class. Furthermore, based on the results of the questionnaire analysis, the average results for each indicator were obtained as follows: (1) self-confidence aspect 68.57 (medium); (2) persistence and perseverance 83.33 (high); (3) open and flexible thinking 80.89 (high); (4) interest and curiosity 80.89 (high); (5) monitor and evaluate 84.38 (high). So the results obtained were that mathematical disposition abilities, especially in the aspect of self-confidence, were still relatively moderate. Furthermore, based on the analysis of the interview results, it was found that the indicators of student self-confidence were still lacking. And the aspect of students' interest and curiosity is quite good. Thus, action is needed to improve students' mathematical disposition abilities in learning mathematics, especially in the aspect of self-confidence. It is hoped that this research will be useful for further research.
