DEVELOPMENT OF MATHEMATICS TEACHING MATERIAL BASED ON REALISTIC MATHEMATICS EDUCATION IN ELEMENTARY SCHOOL

Penelitian ini bertujuan untuk mengembangkan bahan ajar berbasis Realistic Mathematics Education(RME) pada materi pecahan untuk siswa kelas 4 di Sekolah Dasar sehingga menghasilkan bahan ajar yang valid dan praktis digunakan dalam pembelajaran. Jenis penelitian ini adalah penelitian Reasearch and Development (R&D) dengan menggunakan model pengembangan ADDIE yang terdiri dari 5 tahapan yaitu analysis, design, development, implementation, dan evaluation. Penelitian ini dilakukan di SD Islam Raudhah BSD Palembang. Berdasarkan hasil validasi oleh ahli materi bahwa pengembangan bahan ajar matematika berbasis realistic mathematics education dinilai valid dengan skor yang tinggi yaitu 88.63%. Hasil validasi oleh ahli media juga dinilai valid dengan skor yang tinggi yaitu 87,22%. Bahan ajar ini juga bernilai praktis sebagaimana hasil uji prodak terhadap siswa diperoleh skor yang tinggi yaitu 91,94%. Penelitian ini membuktikan bahwa pengembangan bahan ajar matematik berbasis realistic mathematics education sangat layak dan praktis digunakan dalam pembelajaran matematika di sekolah dasar.This study aims to develop teaching material based on Realistic Mathematics Education (RME) on fractions for grade 4 students in elementary schools so as to produce teaching material that is valid and practical to use in learning. This type of research is Research and Development (R&D). Research applies the ADDIE development model which consists of 5 stages suc as analysis, design, development, implementation, and evaluation. This research is conducted at Islamic Elementary School of Raudhah BSD Palembang. Based on the results of validation by material experts that the development of realistic mathematics teaching material based on mathematics education is considered valid with a high score of 88.63%. The results of the validation by media experts were also considered valid with a high score of 87.22%. This teaching material also has practical value as the results of the product test on students obtained a high score of 91.94%. This research proves that the development of mathematics teaching material based on realistic mathematics education is very feasible and practical to use in learning mathematics in elementary school
