PENGEMBANGAN PERANGKAT PEMBELAJARAN DENGAN PENDEKATAN PMRI UNTUK MENINGKATKAN HASIL BELAJAR SISWA KELAS V SD PADA MATERI KUBUS DAN BALOK

Abstract

The problems faced in learning mathematics are students not playing an active role in the learning process, it affects the ability of students to solve mathematical problems. The purpose of this study was to produce learning tools in the form of lesson plans with a Realistic Mathematics Education (PMRI) approach to cube and block material for fifth grade elementary school students. This research uses the type of research development or Research and Development. This research model refers to the development of PLOMP which consists of 5 phases: preliminary investigation, design phase, realization / construction phase, test phase, evaluation and revision (test, evaluation and revision) ), and the implementation phase. Considering COVID-19 the subjects of this study were 8 students in grade V elementary school. Learning devices meet valid criteria based on an evaluation by 3 validators. Then the quality of the lesson plan (RPP) in terms of validity obtained an average score of 3.60 out of a maximum of 4.00. The Quality of Student Worksheets in terms of validity obtained an average score of 3.68 from a maximum score of 4.00. Then for the quality of the questions reviewed in terms of validity obtained an average score of 3.75 from a maximum score of 4.00. As for the quality of the media in terms of validity, the average score was 3.89 from the maximum score of 4.00. Then the results of the analysis include criteria A. Regarding student learning outcomes are taken by giving students with 10 items. Then the scores obtained from group A are 100 while group B is 90.
