Abstract

Mathematical education, as it is now practiced, has many problems. Students that were taught using traditional instruction were only taught to listen. Without the input and feedback of the pupils, the teacher controls the learning process. Students were unable to improve their communication abilities and lacked learning independence. This study aimed to ascertain how case-based learning affected students' mathematics communication skills. The study had a posttest-only design and was a quasi-experimental investigation. The control class received standard instruction, whereas the experiment class received case-based learning instruction. The ability of students to communicate mathematically was the dependent variable in this study. The independent variables in this study were case-based learning and independent variables. Forty-six pre-service mathematics teachers from two full classes served as the research participants in their fifth semester. The tests of prior knowledge and mathematical communication skills were used as study tools. According to the research findings, there is a difference in students' capacity for mathematical communication between those who receive case-based learning instruction and those who receive traditional instruction. The experiment class had better student communication skills than the control group (p-value = 0.047). As a result, case-based learning is one option for enhancing students' communication abilities.

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan pemahaman konsep matematis siswa setelah diterapkan model pembelajaran Team Assisted Individualization dan mendeskripsikan peningkatan kemampuan pemahaman konsep matematis siswa setelah diterapkan model pembelajaran Team Assisted Individualization. Penelitian ini merupakan penelitian quasi eksperimen dengan desain penelitian one group pretest-posttest design. Teknik pengumpulan data dilakukan dengan menggunakan instrumen tes kemampuan pemahaman konsep matematis berbentuk tes essay dan instrumen non tes berbentuk lembar pengamatan (daftar check list). Data dianalisis dengan menggunakan statistik inferensial dengan menggunakan uji One-sample T test, dan statistik deskriptif dengan menggunakan uji  peningkatan gain ternormalisasi (N-gain). Berdasarkan hasil uji One-Sample T test menggunakan SPSS for windows diperoleh nilai sig. 0,000 (sig. ˂ α = 0,05). Hal ini berarti terdapat peningkatan kemampuan pemahaman konsep matematis siswa setelah diterapkan model pembelajaran Team Assisted Individualization, Sedangkan berdasarkan statistik deskriptif menggunakan uji perhitungan gain ternormalisasi diperoleh nilai N-gain yaitu 0,59. Hal ini berarti peningkatan kemampuan pemahaman konsep matematis siswa setelah diterapkan model pembelajaran Team Assisted Individualization diinterpretasikan sedang.
