Abstract

This study aims to examine the implementation of an ethnomathematical approach in teaching three-dimensional geometry using the structure of Batak traditional houses as a local cultural context. Employing a descriptive qualitative method, data were collected through classroom observations, teacher and student interviews, visual documentation, and pre- and post-tests. The findings indicate that using Batak traditional architecture as a learning medium positively impacts students' understanding of volume, surface area, and composite solid shapes. Students showed a significant improvement in post-test scores and greater engagement and enthusiasm during the learning process. The learning became more meaningful as it connected abstract mathematical concepts with students’ socio-cultural realities. However, challenges remain, particularly in media availability and contextual limitations outside specific cultural settings. Overall, the ethnomathematical approach proves to be an innovative strategy to bridge formal mathematics and local cultural heritage.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah terdapat Pengaruh Model Project Based Learning Berbantuan Aplikasi GeoGebra Terhadap Kemampuan Komunikasi Matematis Siswa Di SMP Negeri 5 Tanjung Balai TA 2022/2023. Jenis penelitian ini adalah quasy experiment dengan desain penelitian posttest-Only Control Design. Populasi dajlajm penelitiajn ini ajdajlajh seluruh siswaj kelajs VIII SMP Negeri 5 Tajnjung Bajlaji. Sajmpel yajng diajmbil sebajnyajk duaj kelajs, yajitu kelajs VIII-4 sebajgaji kelajs eksperimen yajng diajjajrkajn menggunajkajn model Project Bajsed Leajrning berbantuan aplikasi geogebra  dajn VIII-5 sebajgaji kelajs control dengajn menggunajkajn model pembelajjajrajn ekspositori. Setelah pembelajaran selesai diberikan, diperoleh nilai rata-rata post test dikelas eksperimen (90,83) sedangkan kelas kontrol (53,61). Hasil uji T diperoleh . Berdasarkan hasil uji T maka  diterima dengan demikian terdapat pengaruh positif dan siginifikan dalam penerapan Model Project Based Learning Berbantuan Aplikasi GeoGebra Terhadap Kemampuan Komunikasi Matematis.  Kata kunci: Project Based Learning, Kemampuan Komunikasi Matematis,                                 Aplikasi Geogebra
