Abstract

Low understanding of fraction concepts among elementary school students remains a common problem in mathematics learning. This condition is influenced by the abstract nature of fractions and the limited use of concrete learning media in schools. This Community Service program aimed to improve students’ learning outcomes and conceptual understanding of fractions through the implementation of Fraction Wheel Media. The method consisted of preparation, implementation, evaluation, and reporting stages. The preparation stage involved observation and interviews with teachers to identify learning problems. The implementation stage included developing the fraction wheel media, preparing usage guidelines, and assisting teachers in applying the media in classroom learning. Evaluation was conducted using pretests, posttests, and observation of students’ learning activities. The results showed a significant improvement in students’ learning outcomes, indicated by an increase in mastery learning percentage from a low initial condition to more than 75% after using the media. In addition, students demonstrated higher motivation, participation, and enthusiasm during learning activities. Teachers also gained new experiences in managing manipulative-based learning. Therefore, the fraction wheel media is effective as an alternative mathematics learning medium for fraction topics and has strong potential for sustainable implementation.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kemampuan komunikasi matematika siswa melalui implementasi asesmen komunikasi matematika pada pembelajaran Sistem Persamaan Linear Dua Variabel (SPLDV) di SMAS Unggulan Harapan Ummat. Program dilaksanakan melalui tahapan analisis kebutuhan, penyusunan instrumen asesmen, pelatihan guru, implementasi asesmen dalam pembelajaran, serta evaluasi dan refleksi. Metode yang digunakan adalah pendekatan kuantitatif deskriptif dengan desain One Group Pretest–Posttest. Instrumen yang dikembangkan meliputi rubrik penilaian komunikasi matematika, lembar tes, dan angket respons siswa. Hasil kegiatan menunjukkan bahwa guru mampu menerapkan asesmen komunikasi matematika secara lebih terstruktur dalam proses pembelajaran. Rata-rata nilai kemampuan komunikasi matematika siswa meningkat dari 79,10 pada pretest menjadi 86,04 pada posttest. Hasil uji Paired Sample t-Test menunjukkan adanya peningkatan yang signifikan setelah implementasi program. Meskipun nilai N-Gain berada pada kategori rendah, respons siswa terhadap pelaksanaan asesmen menunjukkan kategori sangat praktis. Dengan demikian, implementasi asesmen komunikasi matematika memberikan dampak positif terhadap peningkatan kemampuan komunikasi matematika siswa pada materi SPLDV.
