Abstract

Abstract: The low level of students' mathematical representation ability became the background of this study. The research aimed to analyse the effect of implementing the Problem-Based Learning (PBL) model assisted by interactive PowerPoint media and Microsoft Excel on students' mathematical representation ability. The research method used was a quasi-experiment with a pretest-posttest control group design. The sample consisted of 40 eighth-grade students divided into an experimental group and a control group. The research instrument was a mathematical representation ability test that had been validated and proven reliable. Data were analysed using a t-test and N-Gain calculation. The results showed that the N-Gain score in the experimental class reached 0.82 (high category), while in the control class it was only 0.22 (low category). The difference was statistically significant (t = 20.316; p < 0.000). Thus, it can be concluded that integrating PowerPoint and Excel into the PBL model is effective in improving students' mathematical representation ability, particularly in presenting data in the form of graphs and tables. This research implies that a PBL model supported by digital media can serve as an innovative alternative for mathematics learning. Keywords: Problem Based Learning (PBL); Microsoft Excel; Mathematical Representation; Data Centralization; Quasi-Experiment

Abstract

Penelitian ini bertujuan menganalisis pengaruh penerapan model Project-Based Learning berbantuan media PowerPoint Interaktif terhadap pemahaman matematis siswa pada materi relasi dan fungsi. Penelitian menggunakan metode quasi experiment dengan desain Nonequivalent Control Group Design. Sampel penelitian terdiri atas dua kelas VIII SMPN 1 Monta, yaitu kelas VIII B sebagai kelas eksperimen dan kelas VIII C sebagai kelas kontrol yang masing-masing berjumlah 25 siswa. Data dikumpulkan melalui tes pemahaman matematis, observasi, dokumentasi, dan validasi ahli, kemudian dianalisis menggunakan statistik deskriptif dan inferensial yang meliputi uji normalitas, uji homogenitas, Independent Samples t-Test, perhitungan N-Gain, dan Cohen's d. Hasil penelitian menunjukkan bahwa kemampuan pemahaman matematis siswa pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Rata-rata N-Gain kelas eksperimen sebesar 62,66% lebih tinggi daripada kelas kontrol sebesar 41,03%. Hasil Independent Samples t-Test menunjukkan adanya perbedaan yang signifikan antara kedua kelompok setelah perlakuan, dengan nilai effect size yang termasuk kategori sangat besar. Berdasarkan temuan tersebut, dapat disimpulkan bahwa penerapan model Project-Based Learning berbantuan media PowerPoint Interaktif memberikan pengaruh positif terhadap pemahaman matematis siswa pada materi relasi dan fungsi.
