Abstract

The student understanding about mathematical concept, especially on the topic of linear equation in two variables was importance. Aim of this study to develop mathematic material based on Realistic Mathematics Education to build students mathematical concept understanding. The material was developed upon 4-D model of Thiangrajan and was modified to be defined, designed, and developed. Therefore the realistic mathematic education instruction had good contribution on students thinking process. Population of this study are whole students grade VII junior high school of Bina Insan Mandiri and subject consist of ten students who were chose by purposive sampling based on evaluation test and students activity trough instructions. The developed material validated with descriptive analysis while quantitative data were calculated with score average. Based on experts the material was developed has been represented valid and effectiveness criteria based on students tested evaluation, and suitable to the instruction process.

Abstract

Dilatarbelakangi oleh pentingnya pemahaman konsep matematika siswa terutama pada materi Sistem Persamaan Linier Dua Variabel. penelitian ini bertujuan untuk mengembangkan bahan ajar matematika berbasis Realistic Mathematic Education untuk membangun pemahaman konsep siswa. Bahan ajar dikembangkan berdasarkan model 4-D yang direkomendasikan oleh Thiangrajan dan dimodifikasi menjadi defined, designed, dan developed. Dengan demikian, pembelajaran matematika realistik akan mempunyai kontribusi terhadap kemampuan berpikir matematika siswa. Populasi penelitian ini adalah seluruh siswa kelas VIIC Sekolah Bina Insan Mandiri dan subjek penelitian ini terdiri dari sepuluh siswa yang dipilih secara purposive sampling berdasarkan hasil evaluasi dan keaktifan siswa selama pembelajaran. Bahan ajar yang dikembangkan dilakukkan validitas dengan teknik analisas diskriptif, sementara data kantitatif yang diperoleh dihitung berdasarkan rata-rata sekor. Berdasarkan uji validitas oleh ahli instrumen yang dikembangkan dinyatakan valid dan berkriteria efektif berdasarkan hasil uji coba kepada siswa, serta layak untuk digunakan dalam pembelajaran.
