Abstract

Berdasarkan hasil penelitian dan pembahasan tentang kemampuan representasi matematis siswa melalui model PBL, maka diperoleh kesimpulan bahwa siswa yang berkemampuan tinggi dan sedang memenuhi ketiga indikator kemampuan representasi matematis yaitu menuliskan langkah-langkah penyelesaian masalah matematika dengan kata-kata, menyajikan data atau informasi dari suatu masalah ke representasi gambar, diagram, grafik atau tabel , serta  menyelesaikan masalah yang melibatkan ekspresi matematis. Siswa berkemampuan rendah memenuhi dua indikator kemampuan representasi matematis yaitu menuliskan langkah-langkah penyelesaian masalah matematika dengan kata-kata dan menyelesaikan masalah yang melibatkan ekspresi matematis. Disarankan kepada pihak lain untuk melakukan penelitian yang sama pada materi yang berbeda sebagai bahan perbandingan dengan hasil penelitian ini atau materi yang sama namun mendapatan nilai N-Gain dengan kategori “tinggi”.Terima kasih kepada seluruh pihak yang telah ikut serta membantu dan mengevaluasi jurnal ini. terima kasih kepada pembimbing, guru disekolah para dosen dan juga teman-teman semua. Semoga jurnal ini bermanfaat.

Abstract

The purposes of this research is to the differences in mathematical problem-solving skills enhancement and self-efficacy among students who had learned Realistic Mathematics Education (RME) approach and students who received conventional instructions. Reseach use quasi-experimental was used pre-test research design posttest control group design. The experimental group was treated using RME  approach while the control group gain use conventional approach. To gather the instrument is the form of mathematical problem solving ability test, and a questionnaire to determine students' self-efficacy toward mathematics. This research was conducted at Secondary Islamic School . The population is  grade VIII students MTsN Model Banda Aceh inl year 2012/2013. The samples were  two classes, VIII-7, class as the experimental class and the control class VIII-6, by purposive sampling technique. The researc found that studens mathematical problem-solving ability which were taken by with RME approach better than conventional approaches. Based on the analysis of self-efficacy RME class increases more than the self-efficacy of students who received conventional learning. Furthermore there a relationship between the ability of solving mathematical problems with self-efficacy of students in the experimental class and control with very low qualifications.
