PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERBASIS ETNOMATEMATIKA BERORIENTASI DARI KEMAMPUAN REPRESENTASI MATEMATIS SISWA

Abstract

The purpose of this study was to determine the quality of ethnomathematics-oriented student worksheets (LKPD) based on students' mathematical representation abilities produced in this study in terms of valid, practical, and effective criteria that have been set. This type of research is research and development (R&D), namely the development of student worksheets based on ethnomathematics orientated from students' mathematical representation abilities. R&D, namely the development of worksheets developed based on the Plomp model which consists of the initial investigation phase (prelimenary investigation), design (design), realization/construction (realization/construction), test, evaluation and revision (test, evaluation, and revision). The test subjects in this study were class VII-4 students of SMP Negeri 1 Tanjungbalai Asahan. Based on the results of the trials carried out, data obtained from the validation results of experts with an average of 93% is in the very valid category, because 81% - 100% so that the LKPD is said to be very valid. Furthermore, student worksheets were assessed by students with an average response of 93% in the very practical category, and the teacher's response with an average response of 90% in the very practical category. So based on the results of the students' mathematical representation ability test they completed classically with an average of 94% in the very effective category.
