Abstract

Tujuan dari penelitian ini adalah (1) mengembangkan media pembelajaran berbasis smartphone dengan menerapkan Tri-N, (2) mengetahui kualitas media pembelajaran berbasis smartphone dengan menerapkan Tri-N ditinjau dari aspek validitas dan aspek kepraktisan, dan (3) mengetahui keefektifan media pembelajaran berbasis smartphone dengan menerapkan Tri-N. Penelitian ini adalah penelitian dan pengembangan dengan model 4-D (Four D Models) yang meliputi tahap pendefinisian, perancangan, pengembangan, dan diseminasi. Hasil akhir dalam penelitian ini adalah media pembelajaran berbasis smartphone dengan menerapkan Tri-N dan dapat diunduh pada alamat link http://pwastore.com/w/media-pembelajaran-1fa13542b6c5. Media pembelajaran yang dibuat dinyatakan valid, praktis, dan efektif. Media ini dikatakan valid terbukti dari hasil validasi materi, media, dan 3N berturut-turut diperoleh rata-rata skor  (Sangat Baik),  (Sangat Baik), dan  (Baik). Kepraktisan terbukti dari hasil angket respon siswa diperoleh rata-rata skor  (Baik). Keefektifan terbukti dari nilai  dan diperoleh persentase ketuntasan sebesar 78% (Baik).

Abstract

Tujuan penelitian ini adalah untuk meningkatkan keaktifan dan hasil belajar matematika melalui model pembelajaran kooperatif tipe Think Pair Share (TPS). Jenis penelitian ini termasuk Penelitian Tindakan Kelas (PTK). Pelaksanaan tindakan meliputi perencanaan, tindakan, observasi dan refleksi. Subyek dalam penelitian ini adalah siswa kelas VIII C SMP Muhammadiyah 8 Yogyakarta. Teknik pengumpulan data dengan teknik observasi, dokumentasi, angket dan tes. Sebelum digunakan untuk mengambil data dilakukan uji coba instrumen yang meliputi validitas dan reliabilitas. Teknik analisis data keaktifan dengan menghitung jumlah skor keseluruhan sesuai dengan skor yang telah diperoleh pada setiap indikator observasi dan untuk hasil belajar dengan menghitung rata-rata belajar pada setiap siklus. Hasil penelitian menunjukkan ada peningkatan keaktifan belajar dengan rata-rata persentase pada pra siklus 46%, siklus I 61% dan siklus II 79% sedangkan hasil belajar matematika mengalami peningkatan rata-rata pra siklus 57,18, siklus I 66,14 dan pada siklus II menjadi 73,93.

Abstract

This study investigates the effectiveness of E-Worksheets in enhancing students' problem-solving skills, with a specific focus on self-directed learning, in the topic of ratios. The research examines the impact of technology-based learning tools on students' ability to solve problems and explores the relationship between self-directed learning and problem-solving abilities. The study employs a control group design, comparing the performance of students using E-Worksheets with those in a control group. The findings indicate that the use of E-Worksheets significantly improves students' problem-solving skills compared to the control group. Moreover, the analysis reveals a positive association between students' level of self-directed learning and their problem-solving abilities. These findings support the integration of technology in the learning process to create interactive and engaging experiences that foster problem-solving skills. The study emphasizes the importance of cultivating students' self-directed learning and recommends strategies for educators to promote independent problem-solving and collaboration among students. The implications of this research contribute to the understanding of the role of E-Worksheets and self-directed learning in enhancing problem-solving skills and provide valuable insights for future research and educational practices.

Abstract

The use of GeoGebra in mathematics education positively impacts students' mathematical abilities. This meta-analysis examines its overall effectiveness using 10 studies selected from Google Scholar and Scopus based on inclusion criteria. Data were analyzed using RStudio, revealing an overall effect size of 1.31, indicating a highly positive impact. The study also analyzed variability with four moderator variables: education level, publication type, control class type, and mathematical ability. Results show that GeoGebra significantly enhances mathematical abilities based on publication source and control type but is not influenced by education level. Notably, GeoGebra effectively improves students' conceptual understanding of mathematics, making it a valuable tool for enhancing mathematical skills in education. These findings emphasize the significant role of GeoGebra in fostering students' mathematical comprehension.
