Abstract

ABSTRAK Kemampuan penalaran dan kemampuan representasi dalam pembelajaran matematika sangatlah penting. National Council of Teachers of Mathematics (NCTM) menetapkan lima persyaratan kemampuan yang harus dimiliki oleh siswa dalam pembelajaran matematika, yaitu kemampuan pemecahan masalah, kemampuan komunikasi, kemampuan koneksi, kemampuan penalaran dan kemampuan representasi. Berdasarkan dari hasil pra penelitian, siswa kelas VII di SMPN 32 Bandar Lampung masih memiliki kemampuan penalaran dan representasi matematis yang relatif kurang baik, dimana kebanyakan siswa masih banyak yang mendapatkan nilai dibawah rata-rata. Dari 154 siswa, yang mendapatkan nilai diatas rata-rata hanya ada 24 siswa sedangkan 130 siswa mendapatkan nilai dibawah rata-rata . Peneliti tertarik untuk mempraktikan model pembelajaran yang dapat meningkatkan kemampuan penalaran dan representasi matematis siswa. Tujuan penelitian ini untuk mengevaluasi dampak model pembelajaran DMR (Discourse Multy Representation) terhadap kemampuan penalaran dan representasi matematis siswa. Penelitian ini merupakan jenis penelitian Quasy Ekperiment dengan desain penelitian faktorial 2x2. Sampel penelitian ini adalah siswa SMPN 32 Bandar Lampung kelas VII B dan kelas VII D. Teknik pengambilan sampel yang digunakan adalah rendom sampling. Tes adalah metode yang digunakan dalam pengumpulan data penelitian ini . Dalam penelitian ini uji normalitas, daya beda, tingkat kesukaran, dan homogrnitas merupakan teknik analisis data yang digunakan. Menggunakan Uji (MANOVA) untuk menguji hipotesis dalam penelitian ini. Berdasarkan hasil penelitian dan hitungan uji MANOVA, dapat kesimpulan bahwa terdapat pengaruh model pembelajaran DMR terhadap kemampuan penalaran matematis siswa. Terdapat pengaruh model pembelajaran DMR terhadap kemampuan representasi matematis siswa. Terdapat pengaruh model pembelajaran DMR terhadap kemampuan penalaran dan representasi matematis siswa. Kata kunci : Model Pembelajaran DMR (Discourse Multy Representation), Kemampuan Penalaran Matematis, Kemampuan Representasi Matematis. iv ABSTRACT In order to acquire mathematics, reasoning and representational skills are crucial. Students must meet five mathematical ability requirements, according to the National Council of Teachers of Mathematics (NCTM), which include problem-solving abilities, communication skills, connection skills, reasoning abilities, and representation abilities. The reasoning skills and mathematical representations of seventh grade junior high school students at SMPN 32 Bandar Lampung are still relatively low, according to the results of the pre-research. Out of 154 students, only 24 students received scores above the average, while 130 students received scores below the average. Researchers are interested in putting learning models into practice that might enhance students' mathematical representations and reasoning skills. The aim of this study was to examine how students' mathematical representations and reasoning skills were affected by the DMR (Discourse Multirepresentation) learning paradigm. With a 2x2 factorial research design, this study is a particular kind of quasi-experiment. Students from SMPN 32 Bandar Lampung's classes VII B and VII D made up the study's sample. Random sampling is the method that is employed. The test is the method used in this study's data collecting. In this study, the normalcy test, discriminating power, level of difficulty, and homogeneity were employed as data analysis techniques. In this study, the Multivariate Analysis of Variance (MANOVA) Test was utilized to test the hypothesis. The MANOVA test counts and study findings led to the conclusion that the DMR learning model had an impact on students' mathematical reasoning skills. Students' capacities for mathematical representation are influenced by the DMR learning paradigm. The DMR learning paradigm has an impact on how students reason and represent mathematics.Keywords: DMR (Discourse Multirepresentation) Learning Model, Mathematical Reasoning Ability, Mathematical Representation Ability
