Abstract

Penelitian ini bertujuan untuk menghasilkan instrumen tes kemampuan pemecahan masalah dan komunikasi matematis pada materi bangun ruang sisi datar yang tervalidasi, memiliki reliabilitas, daya pembeda (DP), dan indeks kesukaran (IK) yang memadai. Metode penelitian yang digunakan adalah penelitian pengembangan (R&D) dengan tahapan mengidentifikasi potensi dan masalah, mengumpulkan informasi, mendesain produk, melakukan validasi, melakukan revisi, melakukan uji coba, dan melakukan revisi akhir. Instrumen penelitian terdiri dari lembar validasi dan  lembar tes kemampuan pemecahan masalah matematis dan komunikasi matematis. Validasi Instrumen tes dilakukan oleh 5 orang ahli yang terdiri dari 4 orang validator ahli, dan satu orang guru matematika. Subjek uji coba instrumen tes sebanyak 78 orang siswa kelas IX yang sudah belajar materi bangun ruang sisi datar. Hasil penelitian diperoleh seperangkat instrumen untuk mengukur kemampuan pemecahan masalah matematis dan komunikasi matematis yang memadai.
