Abstract

Mathematics learning must be facilitated by students' skills in conveying their creative ideas and the teacher's skills needed to provide constructive learning. One of the abilities that can develop students' thinking skills in learning geometry is spatial ability. Mathematical spatial ability pressure in the field of geometry and is important for students to master. The importance of spatial abilities requires students to have good mathematical spatial abilities. Because learning mathematics cannot be separated from geometry, so with good spatial abilities, mathematical abilities will also be good, especially in the field of geometry. The form of an effort to find out students understand geometry material is by using van Hiele's geometric thinking theory so that they are able to overcome students' difficulties in learning geometry. Van Hiele's stages consist of the visualization stage, the analysis stage, the abstraction stage, the deduction stage, and the rigor stage. ). In this study, we wanted to know the spatial abilities of students at the level of visualization (0) and analysis (1) from van Hiele's theory, namely students' initial ability to recognize geometric elements/components.

Abstract

Abstrak Pembelajaran geometri memerlukan bahan ajar yang sesuai dengan tahap perkembangan kognitif. Materi geometri belum dikaitkan dengan budaya lokal, sehingga pemahaman konsep peserta didik belum optimal. Salah satu yang dilakukan dengan mengembangkan LKPD berbasis etnomatematika mengikuti tahapan berpikir geometri menurut teori Van Hiele, agar pembelajaran mudah dipahami. Penelitian ini bertujuan untuk mengembangkan LKPD geometri sekolah dasar berbasis etnomatematika Padaw Tuju Dulung berdasarkan teori belajar Van Hiele. Metode yang digunakan adalah Research and Development dengan model pengembangan 4D. Data penelitian diperoleh melalui lembar validasi ahli dan angket respon peserta didik, kemudian dianalisis secara deskriptif kualitatif yang didukung oleh data kuantitatif. Hasil penelitian menunjukkan bahwa LKPD yang dikembangkan memperoleh kriteria sangat layak dengan penilaian ahli materi 88,46% dan ahli media 90,21%. Respon peserta didik menunjukkan tingkat kemenarikan 86,36% sangat menarik. LKPD yang dihasilkan memuat unsur budaya Padaw Tuju Dulung dan disusun sesuai tahapan berpikir geometri Van Hiele, sehingga layak digunakan dalam pembelajaran geometri di sekolah dasar. Abstract: Geometry learning requires teaching materials that are appropriate for the stage of cognitive development. The geometry material has not yet been linked to local culture, resulting in suboptimal understanding of concepts among students. One of the approaches taken is to develop ethnomathematics-based Student Worksheets (LKPD) following the stages of geometric thinking according to Van Hiele's theory, so that the learning is easy to understand. This research aims to develop elementary school geometry LKPD based on Padaw Tuju Dulung ethnomathematics according to Van Hiele's learning theory. The method used is Research and Development with a 4D development model. Research data were obtained thru expert validation sheets and student response questionnaires, then analyzed descriptively qualitatively supported by quantitative data. The research results show that the developed LKPD meets the very feasible criteria with a material expert assessment of 88.46% and a media expert assessment of 90.21%. Student responses indicate a very interesting level of 86.36%. The developed LKPD contains elements of Padaw Tuju Dulung culture and is structured according to the Van Hiele geometric thinking stages, making it suitable for use in geometry learning in elementary schools
