Abstract

This study aims to identify the sources and causes of learning difficulties in mathematics among eighth-grade students at SMP Negeri 1 Telaga during online learning. A descriptive research method was employed, with data collected through a Likert-scale questionnaire and semi-structured interviews. The results revealed an average difficulty percentage of 53.40%, with the majority falling into the medium category. Unstable network conditions were identified as the primary source of difficulties (63.91%), while limited interaction and delivery of material were the main causes (59.06%). These findings provide valuable insights for teachers and schools in designing more effective online mathematics learning strategies.

Abstract

Mathematical problem solving ability is a key component of students’ cognitive development, enabling them to understand, analyze, and apply mathematical concepts in various real-life situations. Despite its importance, many students struggle with problem-solving due to teacher-centered approaches and the lack of interactive, concept-oriented instructional models. This study aims to examine the effectiveness of the Heuristic Vee learning model in improving students’ mathematical problem-solving skills, particularly in the topic of two-dimensional shapes. The research employed a quasi-experimental method using a Non-Equivalent Posttest-Only Control Group Design. The participants were two seventh-grade classes at MTs Negeri 1 Kota Gorontalo, selected through purposive sampling based on class equivalence and teacher recommendations. The experimental group received instruction using the Heuristic Vee model, which involved problem exploration, concept mapping, and guided reflection, while the control group was taught through the direct instruction method. Data were collected through a post-test consisting of essay questions based on Polya’s four problem-solving stages. All instruments were validated by experts and tested for reliability. Data analysis included descriptive statistics, normality and homogeneity tests, independent t-tests, and effect size measurement. The results showed that the experimental group achieved a higher mean post-test score (49.83) than the control group (31.70), with a significant t-value of 3.458 > 2.002 at the 5% significance level. The effect size (Cohen’s d = 0.89) was categorized as high. These findings indicate that the Heuristic Vee model significantly enhances students’ mathematical problem-solving skills and serves as an effective strategy for promoting student-centered and meaningful mathematics learning.

Abstract

Penelitian ini merupakan peneltian tindakan kelas yang bertujuan untuk meningkatkan hasil belajar matematika siswa melalui model discovery learning berbantuan wordwall pada materi bentuk aljabar. Subjek penelitian adalah 20 siswa kelas VII MTs Al Mabrur Bone Raya. Penelitian dilaksanakan dalam dua siklus yang terdiri atas tahap perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Teknik pengumpulan data dilakukan melalui instrumen lembar observasi dan tes hasil belajar. Data dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa model discovery learning berbantuan wordwall dapat meningkatkan hasil belajar matematika siswa. Hasil data dari instrumen dianalisis secara keseluruhan dan menunjukkan terjadi peningkatan rata-rata persentase sesudah diterapkan tindakan lanjutan untuk perbaikan proses belajar mengajar pada siklus II. Dimana aspek observasi seluruh aktivitas guru dan aktiivitas siswa serta hasil belajar siswa diperoleh 80% sesuai dengan indikator keberhasilan penelitian. Pada ranah afektif dan psikomotorik setelah perbaikan pada siklus II mengalami peningkatan 80% sesuai dengan indikator keberhasilan penelitian. Untuk itu, dengan menggunakan model pembelajaran discovery learning berbantuan wordwall dalam pembelajaran matematika dapat meningkatkan hasil belajar matematika siswa pada materi bentuk aljabar.

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan berpikir kritis siswa dalam menggunakan multimedia interaktif pada materi segitiga di kelas IV SDN 12 Bukal. Penelitian ini adalah penelitian deskriptif dengan subjek penelitian adalah kelas IV berjumlah 16 siswa. Pengumpulan data dilakukan melalui instrumen tes berbentuk uraian yang telah melalui tahap uji validasi. Untuk mengukur kemampuan siswa dalam berpikir kritis digunakan 4 indikator yaitu : 1) Identifikasi masalah, 2) Analisis, 3) Memecahkan masalah, dan 4) Menarik simpulan. Penelitian menunjukkan bahwa kemampuan berpikir kritis siswa di kelas IV SDN 12 Bukal setelah mengikuti proses pembelajaran yang menggunakan multimedia interaktif tergolong pada kategori sedang dan capaian persentase 66,00%. Selanjutnya untuk hasil setiap indikator juga tergolong pada kategori sedang karena mencapai persentase masing-masing identifikasi masalah 72,92%, analisis 64,58%, memecahkan masalah 63,89%, dan menarik kesimpulan 60,94%.
