Abstract

Penelitian ini bertujuan untuk mengembangkan bahan ajar berbasis etnomatematika guna meningkatkan keterampilan berpikir geometri siswa. Metode yang digunakan adalah model penelitian dan pengembangan dengan pendekatan 4D. Teknik analisis data meliputi penghitungan skor validitas dan kepraktisan melalui kuesioner. Hasil penelitian menunjukkan bahan ajar yang dikembangkan memiliki validitas rata-rata sebesar 85% dan kepraktisan rata-rata 90,5%, menandakan bahwa bahan ajar sangat valid dan sangat praktis digunakan dalam pembelajaran. Keberhasilan ini dicapai melalui integrasi konsep geometri dengan budaya lokal, sehingga pembelajaran menjadi lebih kontekstual, relevan, dan dapat meningkatkan motivasi siswa dalam belajar. This research aims to develop ethnomathematics-based teaching materials to improve students' geometric thinking skills. The method used is a research and development model with a 4D approach. Data analysis techniques include calculating validity and practicality scores through questionnaires. The research results show that the teaching materials developed have an average validity of 85% and an average practicality of 90.5%, indicating that the teaching materials are very valid and very practical to use in learning. This success was achieved through integrating geometric concepts with local culture, so that learning becomes more contextual, relevant, and can increase student motivation in learning.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi digital guru PKBM Hati Nurani Bangsa melalui pelatihan dan pendampingan pembuatan e-module interaktif berbasis aplikasi Book Creator. Metode yang digunakan adalah Participatory Action Research (PAR) dengan tahapan sosialisasi, pelatihan, workshop, pendampingan, dan evaluasi. Sasaran kegiatan adalah 15 guru yang mengajar pada program Paket A, B, dan C di PKBM Hati Nurani Bangsa, Kecamatan Palasah, Kabupaten Majalengka. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada kompetensi literasi digital guru. Skor rata-rata pre-test sebesar 55,3 (kategori rendah) meningkat menjadi 82,6 (kategori tinggi) pada post-test. Sebanyak 87% guru berhasil menghasilkan minimal satu e-module interaktif sesuai mata pelajaran yang diampu. Implementasi e-module dalam kelas juga meningkatkan keterlibatan siswa, dengan 70% peserta didik lebih aktif bertanya dan merespon pembelajaran. Selain itu, terbentuk Tim Penggerak Literasi Digital dan panduan teknis pembuatan e-module sebagai upaya keberlanjutan program. Kegiatan ini membuktikan bahwa pelatihan berbasis praktik langsung dengan pendampingan intensif efektif meningkatkan literasi digital guru dan kualitas pembelajaran. Program ini berpotensi direplikasi di PKBM lain sebagai strategi untuk mendukung transformasi digital pendidikan nonformal.

Abstract

The Role of Ethnomathematical Context in Geometric Reasoning: A Van Hiele-Based Analysis of Indonesian Seventh-Graders. Objective: This study aims to analyze students' geometric thinking skills on plane geometry material based on Van Hiele's theory. An ethnomathematics approach was employed, focusing on the geometric patterns and shapes found in the ornaments, windows, and domes of local mosques, which serve as representations of plane geometry. This study is intended to describe the profile of students' thinking levels and the difficulties that arise at each stage of geometric thinking, without testing the improvement or influence of specific interventions. Methods: The study employed a qualitative descriptive approach with 22 eighth-grader students from a public junior high school in Majalengka Regency, Indonesia, as participants. The instruments used included a diagnostic test based on Van Hiele's theory and unstructured interviews to explore students' reasoning patterns. Data were analyzed using thematic analysis through the stages of reduction, presentation, and conclusion drawing, and validated through triangulation between test and interview results. Classification of thinking levels was carried out by matching students' answers and explanations to the indicators of each Van Hiele level. Findings: The study's results showed a significant decline in the achievement of each level of geometric thinking. All students reached the visualization stage; 81.8% reached the analysis stage, 22.7% reached informal deduction, and only 9.09% reached formal deduction, while no students reached the rigor stage. The sharp decline from the analysis to the deduction stage indicates students' limited ability to connect the properties of shapes and reason logistically. Interviews revealed that the local cultural context facilitated the visualization of shapes, but did not fully encourage higher deductive abilities. Conclusion: Students’ geometric thinking skills are primarily at the stages of visualization and analysis. The use of ethnomathematical contexts has the potential to act as an early cognitive bridge, facilitating students’ recognition of shapes and their properties. Compared to standard geometry problems, ethnomathematical problems better facilitate initial conceptual understanding through their connection to students’ cultural experiences, but their contribution to formal deduction remains limited. Keywords: geometric thinking skills, van hiele's theory, ethnomathematics.
