PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK BERBASIS PROBLEM BASED LEARNING PADA MATERI BILANGAN PECAHAN UNTUK SISWA KELAS IV SD NEGERI 2 RAWA LAUT

Abstract

This study aims to develop teaching materials in the form of Student Worksheets (LKPD) based on Problem Based Learning (PBL) on the material of fractional numbers for fourth graders of SDN 2 Rawa Laut. The type of research is research and development (R&D) using the ADDIE model which has five stages, namely: analysis, design, development, implementation, and evaluation. Based on the results of the study, the Student Worksheets (LKPD) that were developed had a material expert validity score of 100% after going through the revision stage and included in the very feasible criteria, 90% design experts with very feasible criteria, and 87% language experts with very feasible criteria. The validation results from the three experts show that the Problem Based Learning-based mathematics LKPD obtained a very feasible criteria. The response of students and teachers to the use of LKPD in learning obtained an assessment result of 91% and 97% or very interesting. From the effectiveness of using LKPD in learning, it is known that the completeness of mathematics learning outcomes reaches 83%. It can be said that the use of Problem Based Learning-based mathematics LKPD is effective in learning.
