Windi Yoga. (2026). Penerapan Model Discovery Learning Berbantuan Aplikasi Geo Math dalam meningkatkan Kemampuan Spasial Siswa pada Materi Dilatasi. Skripsi. Universitas Syiah Kuala. Di bawah bimbingan Prof. Dr. M. Ikhsan, M.Pd dan Ayu Mastura, S.Pd., M.Pd.
Penelitian ini bertujuan untuk mengetahui apakah kemampuan spasial siswa yang diajarkan melalui model Discovery Learning berbantuan aplikasi Geo Math lebih baik daripada kemampuan spasial siswa yang diajarkan melalui model Discovery Learning tanpa bantuan aplikasi Geo Math pada materi dilatasi. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian quasi experimental design. Desain penelitian yang digunakan adalah Posttest-Only with Nonequivalent Groups Design. Populasi dalam penelitian ini adalah seluruh siswa kelas XI SMA Kartika XIV-1 Unggul Berbasis Talenta Banda Aceh. Teknik pengambilan sampel menggunakan purposive sampling, sehingga diperoleh dua kelas sebagai sampel penelitian, yaitu kelas A dan kelas B yang masing-masing berjumlah 23 siswa. Kelas A diberikan perlakuan menggunakan model Discovery Learning berbantuan aplikasi Geo Math, sedangkan kelas B menggunakan model Discovery Learning tanpa bantuan aplikasi Geo Math. Instrumen penelitian yang digunakan berupa soal uraian kemampuan spasial pada materi dilatasi yang mencakup indikator persepsi spasial, visualisasi spasial, dan orientasi spasial. Data penelitian dianalisis menggunakan uji Independent Samples t-test setelah memenuhi uji prasyarat berupa uji normalitas dan uji homogenitas. Hasil penelitian menunjukkan bahwa kemampuan spasial siswa yang belajar menggunakan model Discovery Learning berbantuan aplikasi Geo Math lebih baik dibandingkan kemampuan spasial siswa yang belajar menggunakan model Discovery Learning tanpa bantuan aplikasi Geo Math pada materi dilatasi. Penggunaan aplikasi Geo Math membantu siswa memvisualisasikan objek geometri secara lebih interaktif sehingga mendukung pemahaman konsep dilatasi dan meningkatkan kemampuan spasial siswa. Hasil penelitian ini mengimplikasikan bahwa integrasi aplikasi Geo Math dalam pembelajaran dengan model Discovery Learning dapat dijadikan sebagai alternatif pembelajaran geometri, khususnya materi dilatasi, untuk memfasilitasi visualisasi konsep secara lebih efektif dan mendukung pengembangan kemampuan spasial siswa.
Kata kunci: kemampuan spasial, Discovery Learning, Geo Math, dilatasi, transformasi geometri.

Windi Yoga. (2026). The Implementation of Discovery Learning Model Assisted by Geo Math Application in Improving Students’ Spatial Ability on Dilation Material. Undergraduate Thesis. Syiah Kuala University. Supervised by Prof. Dr. M. Ikhsan, M.Pd and Ayu Mastura, S.Pd., M.Pd. This study aimed to determine whether the spatial ability of students through the Discovery Learning model assisted by the Geo Math application was better than the spatial ability of students through the Discovery Learning model without the assistance of the Geo Math application on dilation material. This study employed a quantitative approach with a quasi-experimental research design. The research design used was Posttest-Only with Nonequivalent Groups Design. The population of this study consisted of all eleventh-grade students of SMA Kartika XIV-1 Unggul Berbasis Talenta Banda Aceh. The sampling technique used was purposive sampling, resulting in two classes as the research samples, namely class A and class B, each consisting of 23 students. Class A received treatment using the Discovery Learning model assisted by the Geo Math application, while class B received treatment using the Discovery Learning model without the Geo Math application. The research instrument used was an essay test of spatial ability on dilation material covering indicators of spatial perception, spatial visualization, and spatial orientation. The data were analyzed using the Independent Samples t-Test after fulfilling the prerequisite tests, namely the normality test and homogeneity test. The results showed that the spatial ability of students who learned using the Discovery Learning model assisted by the Geo Math application was better than that of students who learned using the Discovery Learning model without the Geo Math application on dilation material. The use of the Geo Math application helped students visualize geometric objects more interactively, thereby supporting students’ understanding of dilation concepts and improving their spatial ability. The findings of this study suggest that integrating the Geo Math application into the Discovery Learning model can be considered an effective instructional alternative for geometry learning, particularly on dilation, as it facilitates more effective visualization of concepts and promotes the development of students' spatial ability. Keywords: spatial ability, Discovery Learning, Geo Math, dilation, geometric transformation.
