Abstract

 Student learning outcomes represent their understanding of subject material and serve as a benchmark for evaluating educational effectiveness. A preliminary investigation at SMA Negeri 7 Gorontalo revealed low student performance in matrix-related mathematics topics. Among various factors influencing learning success, critical thinking stands out as a key internal factor in mathematics education. This study employed a quantitative, descriptive-correlational design with an ex post facto approach. It aimed to assess the mathematical critical thinking skills of Grade XI students and to examine their relationship with learning outcomes on matrix material. Critical thinking was evaluated using four indicators: analyzing, evaluating, explaining, and concluding. Findings indicated that most students had not yet achieved an optimal level of mathematical critical thinking, with an average score of 56.34 across a sample of 50 students. Correlational analysis revealed a significant positive relationship between critical thinking skills and learning outcomes, with critical thinking accounting for 61.62% of the variance in performance. The data suggest that mathematical critical thinking skills play a substantial role in determining student success in matrix material. Given the strong correlation observed, enhancing these skills may lead to measurable improvements in learning outcomes. There is a significant and positive relationship between students' mathematical critical thinking skills and their learning outcomes in matrix material. Efforts to strengthen critical thinking could be an effective strategy to improve academic performance in mathematics.

Abstract

This research aims to develop an e-module on the topic of the Pythagorean Theorem using the RealisticMathematics Education (RME) approach, assisted by Flip PDF Professional The background of thisresearch was the low level of students mathematical understanding, the limited availability of teachingmaterials, and the suboptimal use of technology in the learning process at SMP Negeri 2 Randangan. Theresearch followed the five stages of the ADDIE development model, namely. Analysis, Design,Development, Implementation, and Evaluation. The results of the expert validation for media and contentshowed that the developed e-module fell into the "valid" category, with average scores of 3.36 and 3.37,respectively. The practicality tests also yielded excellent results, with a practicality percentage of 92.50%from teachers and 89.49% from students, both categorized as "very practical." Therefore, this e-modulewas considered suitable and effective for use as a learning resource, particularly for teaching thePythagorean Theorem. It was also found to enhance student engagement and understanding through acontextual and interactive approach.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan media interaktif Wordwall terhadap hasil belajar matematika siswa pada materi operasi bilangan bulat di kelas VII SMP Negeri 1 Talaga Jaya. Metode penelitian yang digunakan adalah eksperimen semu dengan desain pretest–posttest control group design. Subjek penelitian terdiri atas dua kelas, yaitu kelas eksperimen yang menggunakan media Wordwall dan kelas kontrol yang menggunakan media PowerPoint. Instrumen penelitian berupa tes hasil belajar yang telah diuji validitas dan reliabilitasnya. Analisis data dilakukan menggunakan uji t, effect size, dan N-Gain untuk melihat perbedaan hasil belajar serta efektivitas perlakuan.mHasil penelitian menunjukkan adanya perbedaan signifikan antara hasil belajar siswa kelas eksperimen dan kelas kontrol, dengan nilai t-hitung 7,767 > t-tabel 2,011 pada taraf signifikansi 0,05. Rata-rata nilai posttest kelas eksperimen sebesar 90,02, sedangkan kelas kontrol 76,33. Nilai effect size 2,69 menunjukkan pengaruh tinggi, dan N-Gain 0,726 termasuk kategori tinggi. Dapat disimpulkan bahwa media interaktif Wordwall berpengaruh positif dan signifikan terhadap peningkatan hasil belajar matematika siswa. Media ini mampu menciptakan pembelajaran yang aktif, menarik, dan menyenangkan, serta meningkatkan motivasi belajar siswa.
