This study aims to evaluate the mathematical communication skills of eighth-grade junior high school students on the topic of the Pythagorean Theorem. Mathematical communication is essential as it reflects conceptual understanding, procedural skills, and the ability to clearly express ideas both verbally and in writing. A descriptive qualitative approach was used, involving 23 students as participants. Data were collected through essay tests based on NCTM indicators and supported by interviews. The results showed that 73.91% of students had moderate communication skills, 13.04% were in the high category, and some were able to express mathematical ideas and use symbols accurately. These findings highlight the need for more varied and focused instructional strategies, particularly to improve calculation accuracy, mathematical language use, and visual representation of concepts.
Penelitian ini bertujuan mengevaluasi kemampuan komunikasi matematis siswa kelas VIII SMP pada materi teorema pythagoras. Komunikasi matematis penting karena mencerminkan pemahaman konsep, keterampilan prosedural, dan kemampuan menyampaikan ide secara jelas, baik lisan maupun tulisan. Penelitian ini menggunakan pendekatan kualitatif dengan melibatkan 23 siswa. Data dikumpulkan melalui tes esai berdasarkan indikator NCTM dan wawancara sebagai pelengkap. Hasil menunjukkan 73,91% siswa memiliki kemampuan sedang, 13,04% tinggi, dan sebagian mampu menyampaikan ide serta simbol matematika dengan benar. Temuan ini menunjukkan perlunya strategi pembelajaran yang lebih variatif dan terarah, terutama untuk meningkatkan akurasi perhitungan, penggunaan bahasa matematika, dan representasi visual konsep.
