Abstract

Permasalahan dalam penelitian ini adalah rendahnya hasil belajar matematika siswa pada materi bentuk aljabar, yang ditunjukkan oleh kesulitan memahami konsep dasar dan rendahnya keaktifan selama pembelajaran. Media yang digunakan guru juga belum mampu menarik perhatian siswa secara optimal, sehingga dibutuhkan media alternatif yang lebih menarik, visual, dan interaktif. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan powerpoint interaktif terhadap hasil belajar matematika siswa kelas VIII SMP Negeri 8 Mataram Tahun Ajaran 2025/2026. Penelitian menggunakan pendekatan kuantitatif dengan desain Posttest-Only Control Group Design, melibatkan 76 siswa yang dipilih melalui teknik cluster random sampling dan dibagi menjadi kelas eksperimen dan kelas kontrol. Data diperoleh melalui posttest setelah dua pertemuan dan dianalisis menggunakan statistik deskriptif, uji Independent Sample t-test, serta perhitungan effect size. Hasil perhitungan uji-t didapatkan bahwa nilai yang artinya terdapat perbedaan rata-rata hasil belajar antara kedua kelas. Kelas eksperimen memperoleh nilai rata-rata 71,316, lebih tinggi dibandingkan kelas kontrol sebesar 63,553, dengan effect size 0,562 pada kategori sedang. Hasil ini menunjukkan bahwa penggunaan powerpoint interaktif memberikan pengaruh positif terhadap hasil belajar matematika pada materi bentuk aljabar.

Abstract

This study was motivated by the low mathematics learning outcomes of students on the Pythagorean Theorem material, as indicated by difficulties in understanding concepts and low student participation during the learning process. The instructional media used by teachers have not been able to optimally attract students’ attention; therefore, alternative learning media that are more engaging and easier to understand are needed. This study aims to determine the effect of comic-based learning media on the mathematics learning outcomes of eighth-grade students at SMP Negeri 1 Lembar in the 2025/2026 academic year. This study employed a quantitative approach using a Posttest-Only Control Group Design. The research sample consisted of two classes selected using the cluster random sampling technique, namely class VIII B as the experimental class consisting of 33 students and class VIII D as the control class consisting of 32 students. The experimental class was taught using comic-based learning media, while the control class received instruction without the use of comic media. Data were collected through a posttest administered after two learning sessions and analyzed using descriptive statistics, an Independent Samples t-test, and effect size calculations. The results showed that , which is greater than , indicating a significant difference in learning outcomes between the two classes. The mean learning outcome of the experimental class was higher than that of the control class, with an effect size of 1.381, which falls into the large category. Thus, comic-based learning media have a positive and significant effect on students’ mathematics learning outcomes.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan pemecahan masalah matematis siswa ditinjau dari adversity quotient. Penelitian menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Subjek penelitian adalah siswa yang dikelompokkan berdasarkan kategori adversity quotient, yaitu tinggi, sedang, dan rendah. Pengumpulan data dilakukan melalui angket adversity quotient, tes kemampuan pemecahan masalah matematis, serta wawancara untuk memperkuat hasil analisis. Data dianalisis melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Indikator kemampuan pemecahan masalah mengacu pada langkah memahami masalah, merencanakan penyelesaian, melaksanakan penyelesaian, dan memeriksa kembali hasil. Hasil penelitian menunjukkan bahwa siswa dengan adversity quotient tinggi memiliki kemampuan pemecahan masalah matematis yang lebih baik karena mampu memenuhi hampir seluruh indikator secara sistematis dan tepat. Siswa dengan adversity quotient sedang mampu memenuhi sebagian besar indikator, namun masih mengalami kesulitan pada tahap pelaksanaan dan pemeriksaan kembali. Sementara itu, siswa dengan adversity quotient rendah cenderung mengalami kesulitan pada hampir seluruh tahapan pemecahan masalah. Dengan demikian, adversity quotient berperan dalam membedakan kemampuan siswa dalam menyelesaikan masalah matematis. Hasil penelitian ini diharapkan dapat menjadi bahan pertimbangan bagi guru dalam merancang pembelajaran yang mendukung ketahanan siswa dalam menghadapi tantangan matematika. Analysis of Students’ Mathematical Problem-Solving Ability in Terms of Adversity Quotient This study aims to analyze students’ mathematical problem-solving ability in terms of adversity quotient. The study employed a qualitative approach with a descriptive research design. The research subjects were students classified into three categories of adversity quotient, namely high, moderate, and low. Data were collected through an adversity quotient questionnaire, a mathematical problem-solving test, and interviews to strengthen the analysis results. The data were analyzed through the stages of data reduction, data display, and conclusion drawing. The indicators of problem-solving ability referred to the steps of understanding the problem, planning the solution, carrying out the solution, and rechecking the result. The findings showed that students with a high adversity quotient had better mathematical problem-solving ability because they were able to fulfill almost all indicators systematically and accurately. Students with a moderate adversity quotient were able to meet most of the indicators, but they still experienced difficulties at the stages of carrying out the solution and rechecking the result. Meanwhile, students with a low adversity quotient tended to experience difficulties in almost all stages of problem solving. Thus, adversity quotient plays a role in differentiating students’ ability to solve mathematical problems. The results of this study are expected to serve as a consideration for teachers in designing learning that supports students’ resilience in facing mathematical challenges.
