PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERBASIS ETNOMATEMATIKA MENGGUNAKAN PERMAINAN TRADISIONAL LAMPUNG TAPLAK PADA MATERI SEGI EMPAT SEGITIGA KELAS VII SMP SWADHIPA 1 NATAR

Abstract

This research and development is based on the fact that mathematics teaching materials for class VII SMP Swadhipa 1 Natar do not meet the learning needs of students' mathematics and do not bridge mathematics and culture. The teaching materials used are limited to student handbooks. The objectives of this research and development are: 1) to develop and determine the feasibility of ethnomathematics-based worksheets using traditional Lampung tablecloth games on the subject matter of rectangles and triangles in terms of their validity as teaching materials, 2) to find out the response of teachers and students to the developed ethnomathematics-based worksheets, and 3) find out the effectiveness of the Student Worksheets (LKPD) developed in terms of student learning outcomes on the subject of rectangles and triangles. This study uses research and development (R&D) methods with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development model. The results showed that material validation for Student Worksheets (LKPD) with a value of 4.25, media validation with a value of 4.13, and language validation with a value of 4.76, all of which were declared valid. Student responses showed an average of 4.58 in the interesting category, while teacher responses showed an average value of 4.61 in the practical category as teaching materials. After using the developed ethnomathematics-based Student Worksheets (LKPD), the percentage of students' learning completeness reached 90% which indicated that the developed LKPD was effective on students' mathematics learning outcomes in rectangular and triangular material. These results indicate that ethnomathematics-based Student Worksheets (LKPD) for class VII SMP are appropriate for use as teaching materials.
