Dara Damayanti. (2025). Pengaruh Model Problem Based Learning Berbantuan Aplikasi Desmos terhadap Hasil Belajar Siswa pada Materi Fungsi Kuadrat di SMA. [Skripsi Universitas Syiah Kuala]. Di bawah bimbingan Dra.Yuhasriati, M.Pd. dan Dewi Annisa, S.Pd., M.Pd.

Rendahnya hasil belajar matematika siswa, khususnya pada materi fungsi kuadrat disebabkan oleh kurangnya pemahaman konsep, kesulitan menggambar grafik, serta minimnya keterlibatan aktif siswa selama proses pembelajaran. Salah satu solusi yang diyakini dapat mengatasi permasalahan tersebut adalah penggunaan model problem based learning berbantuan aplikasi Desmos. Penelitian ini bertujuan untuk mengetahui pengaruh model problem based learning berbantuan aplikasi Desmos terhadap hasil belajar siswa pada materi fungsi kuadrat di kelas X SMA Negeri 2 Timang Gajah. Penelitian ini merupakan studi kuasi eksperimen dengan pre-test post-test control group design. Populasi penelitian adalah seluruh siswa kelas X SMA Negeri 2 Timang Gajah dengan sampel dua kelas yang dipilih secara simple random sampling, yaitu kelas X IPAS 1 sebagai kelas eksperimen dan kelas X IPAS 2 sebagai kelas kontrol, masing-masing terdiri atas 32 siswa. Data dalam penelitian ini adalah nilai hasil belajar pada materi fungsi kuadrat. Pengumpulan data dilakukan dengan menggunakan instrumen tes hasil belajar pada materi fungsi kuadrat berupa soal uraian yang disusun oleh peneliti dan telah divalidasi oleh ahli. Data dianalisis menggunakan statistik uji-t independen. Berdasarkan hasil analisis data dengan taraf signifikansi α = 1% diperoleh nilai t_hitung sebesar 14,99 lebih dari t_tabel 2,388. Hal ini menunjukkan bahwa terdapat pengaruh yang sangat signifikan model problem based learning berbantuan aplikasi Desmos terhadap hasil belajar siswa pada materi fungsi kuadrat di kelas X SMA Negeri 2 Timang Gajah.

Dara Damayanti. (2025). The Influence of Models Problem Based Learning Desmos Application Assistance on Student Learning Outcomes on Quadratic Function Material in Senior High School. [Syiah Kuala University Thesis]. Under the guidance of Dra.Yuhasriati, M.Pd. and Dewi Annisa, S.Pd., M.Pd. The low achievement in students' mathematics learning outcomes, particularly in the topic of quadratic functions, is attributed to a lack of conceptual understanding, difficulties in graphing functions, and limited active student engagement during the learning process. One proposed solution to address these challenges is the implementation of the Problem-Based Learning (PBL) model supported by the Desmos application. This study aims to investigate the effect of the Problem-Based Learning model assisted by Desmos on students' learning outcomes in quadratic function material in Grade X at SMA Negeri 2 Timang Gajah. This research employed a quasi-experimental design with a pre-test–post-test control group design. The population consisted of all Grade X students at SMA Negeri 2 Timang Gajah. Two classes were selected as samples through simple random sampling: Class X IPAS 1 as the experimental group and Class X IPAS 2 as the control group, with 32 students in each class. The data in this study comprised students’ learning outcomes in the topic of quadratic functions. Data were collected using a learning achievement test in the form of essay questions developed by the researcher and validated by experts. The data were analyzed using an independent t-test. Based on the analysis at a significance level of α = 1%, the obtained t-value was 14.99, which exceeds the critical t-table value of 2.388. This indicates that the Problem-Based Learning model assisted by the Desmos application has a statistically significant effect on students' learning outcomes in quadratic functions in Grade X at SMA Negeri 2 Timang Gajah.
