Raisa Amalia. (2026). Implementasi Model Discovery Learning Berbantuan Aplikasi Geo Math untuk Meningkatkan Kemampuan Spasial Siswa SMA dalam Memahami Materi Refleksi. [Skripsi. Universitas Syiah Kuala]. Di bawah bimbingan Prof. Dr. M. Ikhsan, M.Pd dan Ayu Mastura, S.Pd., M.Pd.
Kemampuan spasial merupakan kemampuan penting dalam pembelajaran geometri karena membantu siswa memahami hubungan keruangan dan memvisualisasikan objek. Namun, kemampuan spasial siswa pada materi refleksi masih tergolong rendah. Salah satu upaya untuk meningkatkannya adalah melalui penerapan model Discovery Learning berbantuan aplikasi Geo Math. Penelitian ini bertujuan untuk mengetahui apakah kemampuan spasial siswa yang belajar menggunakan model Discovery Learning berbantuan aplikasi Geo Math lebih baik dibandingkan dengan siswa yang belajar menggunakan model Discovery Learning tanpa bantuan aplikasi Geo Math. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis Quasi Experimental Design dan desain Posttest-Only with Nonequivalent Groups Design. Populasi penelitian berjumlah 68 siswa kelas XI yang seluruhnya dijadikan sampel melalui teknik total sampling. Kelas XI-1 sebagai kelas eksperimen A memperoleh pembelajaran menggunakan model Discovery Learning berbantuan aplikasi Geo Math, sedangkan kelas XI-2 sebagai kelas eksperimen B memperoleh pembelajaran menggunakan model Discovery Learning tanpa bantuan aplikasi Geo Math. Data dikumpulkan melalui tes kemampuan spasial berbentuk soal uraian dan dianalisis menggunakan uji Independent Samples t-Test. Hasil penelitian menunjukkan bahwa kemampuan spasial siswa pada kelas yang menggunakan model Discovery Learning berbantuan aplikasi Geo Math lebih baik dibandingkan dengan kelas tanpa bantuan aplikasi Geo Math. Hasil uji-t diperoleh 4,00 > 1,668, sehingga H₀ ditolak. Implikasi penelitian ini menunjukkan bahwa aplikasi Geo Math dapat menjadi alternatif media pembelajaran yang efektif untuk membantu meningkatkan kemampuan spasial siswa pada materi refleksi.

Raisa Amalia. (2026). The Implementation of the Discovery Learning Model Assisted by the Geo Math Application to Improve Senior High School Students' Spatial Ability in Understanding Reflection Material. [Undergraduate Thesis, Syiah Kuala University]. Supervised by Prof. Dr. M. Ikhsan, M.Pd. and Ayu Mastura, S.Pd., M.Pd. Spatial ability is an essential skill in geometry learning as it enables students to understand spatial relationships and visualize objects. However, students' spatial ability in reflection material is still relatively low. One effort to improve this ability is through the implementation of the Discovery Learning model assisted by the Geo Math application. This study aimed to determine whether the spatial ability of students who learned through the Discovery Learning model assisted by the Geo Math application was better than that of students who learned through the Discovery Learning model without the Geo Math application. This study employed a quantitative approach using a Quasi-Experimental Design with a Posttest-Only Nonequivalent Groups Design. The population consisted of 68 eleventh-grade students, all of whom were selected as the sample using the total sampling technique. Class XI-1, as Experimental Group A, was taught using the Discovery Learning model assisted by the Geo Math application, while Class XI-2, as Experimental Group B, was taught using the Discovery Learning model without the Geo Math application. Data were collected through a spatial ability essay test and analyzed using the Independent Samples t-test. The results showed that the spatial ability of students in the class taught using the Discovery Learning model assisted by the Geo Math application was higher than that of students taught without the Geo Math application. The t-test result indicated that 4,00 > 1,668, leading to the rejection of H₀. The findings imply that the Geo Math application can serve as an effective instructional medium to help improve students' spatial ability in learning reflection.
