Abstract

Penelitian ini bertujuan guna mendeskripsikan kemampuan pemecahan masalah matematis ditinjau dari self confidence siswa pada materi sistem persamaan linear dua variabel. Penelitian ini menggunakan penelitian kualitatif deskriptif. Subjek pada kelas VIIIB SMP Negeri 3 Losari sebanyak 6 siswa dengan kategori self confidence tinggi, sedang, dan rendah. Instrumen terdiri atas angket self confidence, tes tertulis kemampuan pemecahan masalah matematis, dan wawancara yang telah diuji terlebih dahulu oleh ahli matematika dan kemudian data dianalisis menggunakan 3 tahap yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa dengan kategori self confidence tinggi mampu memenuhi 4 indikator kemampuan pemecahan masalah matematis menurut Polya, siswa kategori self confidence sedang hanya mampu memenuhi 2 indikator diantaranya menyusun rencana, dan melihat kembali jawaban keseluruhan. Sedangkan siswa kategori self confidence rendah tidak mampu memenuhi indikator memahami masalah, menyusun rencana, melaksanakan rencana penyelesaian, maupun melihat kembali jawaban keseluruhan. Dapat disimpulkan bahwa semakin tinggi self confidence yang dimiliki maka akan lebih mudah dalam menyelesaikan suatu permasalahan matematis, dan sebaliknya jikalau self confidence siswa rendah maka akan lebih sulit juga dalam menyelesaikannya.

Abstract

Considering that mathematics has an important role in learning and in everyday life, the process of learning mathematics that hones the problem solving skills of people who play a role in solving the problem, usually mathematics based on this problem uses questions that contain elements of contextual problems that intersect with students' daily lives. . The aim is to describe students' mathematical problem solving abilities on the material of a two-variable system of linear equations. Class VIII students are the subjects of this research. The indicators according to Polya are (1) Understanding the Problem, (2) Developing a Plan, (3) Implementing a Solution Plan, (4) and Reviewing the Overall Answer. The result of this research is to have an average in the medium category. In the process of completing all Polya indicators, students were able to meet all indicators, but students who had moderate mathematical problem solving abilities were only able to fulfill the indicators of planning and reviewing overall answers, while students with low mathematical problem solving abilities could not fulfill all existing indicators.Keywords: mathematical problem solving ability, system of two variable linear equations.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1839-1849
