Peningkatan kemampuan pemecahan masalah matematis dan kemandirian belajar siswa melalui model problem-based learning berbantuan question card

Abstract This study is motivated by the low mathematical problem solving ability and learning independence. This study aims to determine the difference in the improvement of mathematical problem solving ability and student learning independence between students who get the Problem Based Learning model assisted by Question Card and Direct Instruction assisted by Question Card as well as the relationship between the improvement of problem solving ability and the improvement of student learning independence. The research method used was quasi-experiment with nonequivalent pretest-posttest control group design. The population of this study were all students of class VIII MTs Negeri 1 Garut with samples taken by purposive sampling as many as two classes, namely class VIII-6 and class VIII-5 each with 32 students. The research instruments used were mathematical problem solving ability test and learning independence questionnaire. The results of the analysis showed that: There is a difference in the improvement of students' mathematical problem solving ability between those who get the Problem Based Learning learning model assisted by Question Card and Direct Instruction assisted by Question Card; and There is a difference in the improvement of students' learning independence between those who get the learning model. Abstrak Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah matematis dan kemandirian belajar. Penelitian ini bertujuan untuk mengetahui perbedaan peningkatan kemampuan pemecahan masalah matematis dan kemandirian belajar siswa antara siswa yang mendapatkan model Problem Based Learning berbantuan Question Card dan Direct Instruction berbantuan Question Card serta hubungan antara peningkatan kemampuan pemecahan masalah dan peningkatan kemandirian belajar siswa. Metode penelitian yang digunakan yaitu kuasi eksperimen dengan desain penelitian nonequivalent pretest-posttest control group design. Populasi penelitian ini adalah seluruh siswa kelas VIII MTs Negeri 1 Garut dengan sampel yang diambil secara purposive sampling sebanyak dua kelas yaitu kelas VIII-6 dan kelas VIII-5 masing-masing sebanyak 32 siswa. Instrumen penelitian yang digunakan berupa tes kemampuan pemecahan masalah matematis dan angket kemandirian belajar. Hasil analisis menunjukan bahwa: Terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis siswa antara yang mendapatkan model pembelajaran Problem Based Learning berbantuan Question Card dengan Direct Instruction berbantuan Question Card; Terdapat perbedaan peningkatan kemandirian belajar siswa antara yang mendapatkan model pembelajaran Problem Based Learning berbantuan Question Card dengan Direct Instruction berbantuan Question Card; dan Terdapat hubungan yang signifikan antara peningkatan kemampuan pemecahan masalah matematis dengan peningkatan kemandirian belajar siswa.
