PENGEMBANGAN PERANGKAT PEMBELAJARAN BERBASIS PENDEKATAN MATEMATIKA REALISTIK UNTUK MENINGKATKAN KEMAMPUAN PENALARAN MATEMATIS DAN SELF EFFICACY SISWA SMP NEGERI 3 MUARA SIATAS BARITA

This study aims to describe the development of learning tools based on valid, practical realistic mathematics approaches, and to find effective tools used to improve mathematical reasoning abilities and self-efficacy. Describes increasing students' mathematical reasoning abilities through the development of learning tools with a realistic mathematical approach, and describes increasing students' self-efficacy through developing learning tools with realistic mathematical approaches in class VII SMP Negeri 3 Muara Siatas Barita. This research includes development research (Development Research). In this study, the Thiagarajan learning device development model was used. The subjects of this study were students of class VII-B of SMP Negeri 3 Muara Siatas Barita for the academic year 2021/2022 as many as 32 students. As objects in this research are learning tools, namely Learning Implementation Plan (RPP), Teacher's Book (BG), Student's Book (BS), Student's Mathematical Self Efficacy Questionnaire and Student's Reasoning Ability Test. The results of the study, namely learning tools based on Realistic Mathematics Approach (PM) were valid to be used to improve mathematical reasoning abilities and self-efficacy of seventh grade students of SMP Negeri 3 Muara Siatas Barita. There was an increase in students' mathematical reasoning abilities through the development of learning tools that were developed based on a realistic mathematical approach in class VII SMP Negeri 3 Muara Siatas Barita. Learning tools based on Realistic Mathematics Approach (PM) are practically used to improve mathematical reasoning abilities and self-efficacy of seventh grade students of SMP Negeri 3 Muara Siatas Barita. There was an increase in student self-efficacy through the development of learning tools developed with a realistic mathematical approach in class VII SMP Negeri 3 Muara Siatas Barita
