PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) PADA MATERI PENJUMLAHAN PECAHAN PENYEBUT TAK SAMA BERBASIS PROBLEM SOLVING DIKELAS IV SD

Abstract

This research is motivated by the condition that there are not many schoolsthat implement LKPD in accordance with the requirements and steps for preparing Student Worksheets (LKPD). The Student Worksheet (LKPD) is a learning tool that is able to facilitate students in increasing their understanding of a certain material. LKPD is a sheet that contains the stages of students in making the discovery of a concept independently. This worksheet will feel more meaningful and the concepts obtained will always be remembered in the minds of students. However, there are still many schools that only provide LKPD in the form of practice questions and material from theme books. So that the existing LKPD in general has not been able to facilitate students in increasing knowledge and highlevel thinking such as problem solving. Educators should always conduct analysis and development of LKPD which aims to obtain an LKPD that is in accordance with the needs and characteristics of students. In this development research, the aim is to obtain a Student Worksheet (LKPD) based on Problem Solving on the Addition of Fractions with Unequal Denominators in Grade IV Elementary School. This study uses the ADDIE development model, from Branch (2009:2) which has 5 stages, namely Analysis, Design, Development, Implementation and Evaluation. The validation in this study was carried out by 3 experts, namely material experts, media experts and classroom teachers. The results of the material expert validation have an assessment score percentage of 93% which are included in the feasible category. The results of the media expert's validation obtained a percentage value of 100% in the feasible category. And the results of the validation of the fourth grade elementary school teachers get a percentage value of 91.98% in the appropriate category. so that with the results of the validation, LKPD can be said to be feasible and can be used as a learning tool in schools. Evaluation of the development of LKPD media as a learning medium shows that students tend to prefer LKPD which are more varied and interesting because students prefer to use pictures or concrete objects so that they are easy to understand.
