Kemampuan Memeriksa Kembali (looking back) Siswa SMP dalam Menyelesaikan Masalah Matematika
Abstract
Abstract: The purpose of this research is to describe the ability of looking back students of SMP Negeri 2 Tegalsiwalan Probolinggo regency in solving rectangular shape problems. The research method used is descriptive qualitative. Subjects of this research is three students who had knowledge of geometry level 2 (Informal Deduction) based on Van Hiele's theory. The results showed that subjects at level 2 (Informal Deduction) knowledge of Van Hiele's geometry were able to carry out looking back steps in solving mathematical problems. In addition, the subject is also able to provide more than one way of solving problems and can train students' ability to solve problems.
Abstrak: Tujuan penelitian ini adalah mendiskripsikan kemampuan memeriksa kembali (looking back) siswa SMP Negeri 2 Tegalsiwalan Kabupaten Probolinggo dalam menyelesaikan masalah bangun datar segiempat. Metode penelitian yang digunakan adalah deskriptif kualitatif. Subjek penelitian ini adalah tiga siswa yang memiliki pengetahuan geometri tingkat 2 (Deduksi Informal) berdasarkan teori Van Hiele. Hasil penelitian menunjukkan bahwa subjek mampu melaksanakan langkah looking back dalam menyelesaikan masalah matematika. Selain itu, subjek juga mampu memberikan lebih dari satu cara dalam menyelesaikan masalah dan dapat melatih kemampuan siswa dalam menyelesaikan masalah.Keywords
