PENGEMBANGAN BAHAN AJAR LKS (LEMBAR KERJA SISWA) BERBASIS KONTEKSTUAL UNTUK MENINGKATKAN PEMAHAMAN SISWA DALAM OPERASI HITUNG PERKALIAN BILANGAN PECAHAN KELAS VSD

Abstract

The results showed that the product (LKS) was contextually based with the operating material of calculating fractional numbers for elementary school V grade students using the research and development research type with the Borg and Gall Version with a research procedure using seven steps of work resulting in a contextual-based LKS teaching material development design that can improve the understanding of the operation of calculating fractional number multiplication of SDN class V students  The accuracy and validation results from material experts, media and teachers show a fairly high interpretation. Obtained percentage and eligibility criteria for content 87% (very feasible), eligibility for presentation 75% (feasible), contextual assessment 81% (feasible), feasibility of graphing 79% (feasible), and language assessment 85% (worthy). Contextual-based LKS affected cognitive learning outcomes indicated by a t test significance value of 0.000 < 0.05. Gain test of 0.37 with medium criteria, percentage of student and teacher response after use of contextually based LKS is classically 90.9% with very positive criteria, student response percentage is classically 81.15% with positive criteria. The conclusion of this research is a contextual-based LKS developed for the operating material of calculating fractional numbers for elementary school V grade students in class V students is feasible and effective to use as an alternative teaching material in schools.
