Abstract

This community service activity aims to improve the competency of junior high school mathematics teachers at UPTD SMP Negeri 1 Jorlanghataran in making ICT-based mathematics learning media that are in accordance with the independent learning curriculum. Making ICT-based mathematics learning media is an alternative that teachers must have to increase their competence. On the other hand, this activity can improve teacher skills in writing teaching materials using instructional media. The method used in this community service activity is a collaborative-participatory dialogic approach including socialization and in-house training (lectures, questions and answers, discussions) for delivering material, hands-on practice for making learning media. To ensure the sustainability of training results and to receive support in improving the quality of learning, participants were given the task of making learning media outside of training hours. The training participants in the community service program activities totaled 50 participants. The participants stated that this activity was very useful and a new experience. This community service activity could run smoothly, well and even for the next activity they asked to be included again.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis siswa pada materi sudut dalam lingkaran ditinjau dari gaya belajar visual di SMA Negeri 1 Siantar. Penelitian ini menggunakan metode deskriptif kualitatif dengan subjek siswa kelas XI tahun ajaran 2025/2026. Instrumen penelitian terdiri dari tes uraian, angket gaya belajar, dan wawancara, yang dianalisis berdasarkan empat indikator kemampuan berpikir kritis yaitu interpretasi, analisis, evaluasi, dan inferensi. Data diperoleh melalui tes tertulis, penyebaran angket, serta wawancara mendalam terhadap siswa bergaya belajar visual yang mewakili kategori tinggi, sedang, dan rendah.Hasil penelitian menunjukkan bahwa sebagian besar siswa memiliki gaya belajar visual, namun kemampuan berpikir kritis mereka masih bervariasi. Siswa pada kategori tinggi mampu memenuhi keempat indikator berpikir kritis, siswa kategori sedang hanya menguasai sebagian indikator, sedangkan siswa kategori rendah masih kesulitan terutama pada aspek analisis dan evaluasi. Hal ini menunjukkan bahwa gaya belajar visual dapat mendukung pemahaman konsep sudut dalam lingkaran, tetapi dibutuhkan media pembelajaran visual yang lebih interaktif agar kemampuan berpikir kritis siswa dapat berkembang secara optimal
