Utilization of Collaborative Problem Solving of Mathematical Representation in Solving One Variable Linear Equation Problems

Penelitian ini bertujuan untuk melihat dan mendeskripsikan kemampuan representasi matematis siswa pada materi Persamaan Linier Satu Variabel (PLSV) setelah diterapkan model Collaborative Problem Solving (CPS). Metode penelitian yang digunakan adalah deskriptif dengan analisis data secara kuantitatif kualitatif sesuai indikator matematis. dilaksanakan di SMP Negeri 6 Indralaya Utara kelas VII.1 melibatkan sebanyak 16 sebagai subjeknya. Pengumpulan dilakukan memberikan tes tertulis berupa soal uraian hasil wawancara siswa. Teknik meliputi memeriksa merujuk yaitu visual, simbolik verbal. Data telah terkumpul kemudian dianalisis berdasarkan pedoman penskoran Hasil selanjutnya dikelompokkan menjadi tiga kategori tinggi, sedang, rendah. Berdasarkan didapatkan bahwa persamaan linier satu variabel diterapkannya CPS berada dikategori sedang nilai rata-rata sebesar 59,687 skor visual 71,093, 60,156, verbal 35,937.This study aims to look at and describe students' mathematical representation abilities in the One Variable Linear Equation material after applying (CPS) model. The research method used is descriptive with quantitative qualitative analysis according indicators of representation. This was conducted class involving students as subjects. collection carried out by giving written tests form description questions results interviews students. technique includes examining test referring representation, namely symbolic that has been collected then analyzed based on scoring guidelines refer are grouped into three categories, high, medium, low. Based analysis, it found one-variable linear equations implementation were moderate category an average score 59.687 for 71.093, 60.156, 35.937.
