Hasil penelitian ini adalah (1) tidak terdapat perbedaan yang signifikan kemampuan pemecahan masalah siswa yang diajarkan dengan model CPS dan model RBL, (2) tidak terdapat perbedaan yang signifikan rata-rata kemampuan representasi matematis siswa yang diajar model CPS dan model RBL ditinjau dari gender laki-laki, dan (3) terdapat perbedaan yang signifikan rata-rata kemampuan representasi matematis sisa yang diajar model CPS dan model RBL ditinjau dari gender perempuan. AbstractThe purpose of this study is to understand (1) the ability to solve mathematical problems of students taught with the Creative Problem Solving (CPS) model and the Resource-Based Learning (RBL) model in terms of gender, (2) solutions to students' mathematical problem solving abilities taught by the CPS model and the RBL model in terms of male and female gender. This research is a Quasi Experiment. While the design used in this study is the Only Posttest Control Design. The population in this study were all class VIII in Margasari 3 Public Middle School. The sample in this study was class VIII As a CPS class model totaling 31 students, Class VIII F as a RBL class model totaling 32 students. Data collection techniques using tests, and regulations. The data analysis technique in this research is the analysis prerequisite test that is normality test and homogeneity test using SPSS. Hypothesis testing conducted in this study uses a two-way variant analysis technique and an independent t-test using SPSS. The results of this study are (1) there is no significant difference between the ability to overcome problems with CPS students and the RBL model, (2) there is no significant difference in the average mathematical representation ability of students taught by the CPS model and the RBL model in terms of male gender men, and (3) the CPS difference model and the RBL model in terms of female gender.

Abstract

Kemampuan pemecahan masalah matematis merupakan aspek penting dalam matematika tetapi kemampuan pemecahan masalah mahasiswa masih rendah. Hal ini dipengaruhi oleh banyak factor. Kecenderungan tipe kepribadian yang dimiliki mahasiswa mempengaruhi output mereka ketika memecahkan masalah. Faktor lain adalah model pembelajaran yang digunakan masih kurang dalam mengembangkan kemampuan pemecahan masalah matematis mahasiswa. Pembelajaran menggunakan model PBL berbasis etnomatematika merupakan salah satu cara melatih kemampuan pemecahan masalah dan menguatkan kecintaan mahasiswa terhadap budaya. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah mahasiswa melalui model PBL berbasis etnomatematika ditinjau dari kepribadian topologi hippocrates dan galenus tipe Cholearis dan Phlegmatis. Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek dalam penelitian ini adalah mahasiswa pendidikan matematika semester IV. Pemilihan subjek menggunakan teknik purposive sampling. Teknik pengumpulan data dengan menggunakan observasi, angket, wawancara, dan dokumentasi. Validitas data menggunakan triangulasi. Teknik analisis data menggunakan model  Miles and Huberman yaitu Data Reduction (Reduksi Data), Data Display (Penyajian data), Conclusing Drawing/ Verification (Menarik Kesimpulan dan Memverivikasi Kesimpulan). Keywords:Kemampuan Pemecahan Masalah, PBL Berbasis Etnomatematika, Kepribadian Topologi Hippocrates dan Galenus Tipe Cholearis dan Phlegmatis
