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.

Abstract

This study aims to determine the development of a valid, practical, and effective mathematical logical thinking ability test instrument for flat geometry material for students at SMP Negeri 3 Mojoagung. This instrument is designed to objectively measure students' logical reasoning ability in solving problems related to geometric concepts of flat geometry. This research is a Research and Development (R&D) study, adapting the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research procedure follows the ADDIE model development stages: Analysis, Design, Development, Implementation, and Evaluation. These stages are carried out sequentially and systematically to produce a valid, practical, and effective instrument. The results of this study indicate that the developed test instrument meets good quality criteria, namely the mathematical logical thinking ability test instrument (TKBLM) for flat geometry material is declared valid, practical, and effective. The validity of the TKBLM instrument can be seen from the TKBLM instrument validation percentage, which is 93%, categorized as very valid. The practicality of the TKBLM instrument can be seen from the percentage of the readability questionnaire, where 85% of students' results showed a ???? ≥ 75%. Meanwhile, the effectiveness of the media can be seen from the TKBLM results, where for each indicator, at least one student met the logical mathematical thinking indicator. Thus, this test instrument is suitable for use as an effective measurement tool to evaluate students' logical mathematical thinking skills in the material on plane figures. Keywords: Test Instrument, Logical Mathematical Thinking, Plane Figures.
