PENGEMBANGAN PERANGKAT PEMBELAJARAN BERBASIS PENDEKATAN REALISTIC MATHEMATICS EDUCATION (RME) DENGAN METODE SAINTIFIK

This research uses Research and Development (R & D) method with ADDIE development model which includes analysis, design, development, implementation, and evaluation. The results of the assessment of learning devices conducted by two expert lecturers and mathematics teachers showed that learning tools developed valid and meet the minimum criteria either. Assessment of RPP by one lecturer of material and mathematics teacher got score 4.19 with valid classification. While the assessment of LKS by two expert lecturers and math teachers get a score of 4.30 with a classification is very valid. The result of questionnaire analysis of teacher and student response shows that learning device is said to be practical with a total average value of 4.14. From the observation of the implementation of learning shows good classification with the average percentage of learning implementation reaches 86.7%. The result of students' competence assessment showed that learning device is said to be very effective because it meets 82,14% classical completeness classification
