Abstract

Penelitian yang dilakukan bertujuan memperoleh kevalidan, kepraktisan dan keefektifan media pembelajaran berbasis web terhadap kemampuan komunikasi matematis siswa pada materi unsur-unsur bangun ruang sisi datar. Jenis penelitian Research and Development (RnD). Dari hasil penilitian pengembangan media pembelajaran berbasis web pada materi bangun ruang sisi datar kelas VIII SMP Negeri 13 Pontianak dapat disimpulkan bahwa: Pertama: peneliti menggunakan modifikasi model 3-D yaitu tahap define, design, develop dari model pengembangan 4-D oleh Thiagarajan. Kedua: Media memiliki kevalidan mencapai rata-rata 90,41% dengan kriteria sangat valid, kepraktisan memiliki rata-rata 93% dengan kriteria sangat praktis, dan tingkat keefektifan dari uji coba pretest dan posttest pada N-Gain sebesar 73,86% dengan kriteria cukup efektif. Ketiga: Media dikemas dan ditampilkan dengan menarik menggunaan gambar, audio, serta latihan soal yang tidak membosankan. Hal ini membantu menciptakan lingkungan belajar yang interaktif dan membantu siswa untuk memperdalam ilmu dengan lebih antusias.

Abstract

Abstract: This qualitative descriptive study aims to determine and analyze students' mathematical reasoning abilities and self-concepts in terms of gender in seventh grade junior high school students based on triangles and quadrilaterals. The subjects of this study were students of class VII SMP, totaling 22 students. The research instrument was in the form of a test consisting of four description questions and 20 self-concept questions. The indicators of mathematical reasoning that are measured are drawing sketches, analogies, proportional reasoning, and generalizations. The results of this study showed that the mathematical reasoning abilities of female students performed better than male students. In addition, students' self-concept analysis based on questionnaire data on mathematical reasoning abilities was in the good category.Keywords: Mathematical Reasoning; Self Concept; Gender
