Abstract
The purposes of this research were to determine: (1) is there a significant difference between the mathematical deductive reasoning abilities of students before and after learning of modeling the way (2) whether learning of modeling the way can improve the mathematical deductive reasoning abilities of students. The research was a quasi-experimental research, with one group pretest-posttest design. The location of this research was in MA NW Kabar, Sakra Sub-District, East Lombok Regency. The sample of this research were students of class XI MA NW Kabar. Instrument of this research was the mathematical deductive reasoning abilities test. The data of this research was analyzed using descriptive statistics with paired sampel t-test. The results of the research indicated as follows: (1) There is a significant difference between the mathematical deductive reasoning abilities of students before and after learning of modeling the way; (2) Based on the average and percentage of the mathematical deductive reasoning abilities test of students, the average of pretest is 49.48 with 40% of the students have the mathematical deductive reasoning abilities with good category, the average of posttest is 68.09 with 80% of the students have the mathematical deductive reasoning abilities with good category, it shows that the learning of modeling the way can improve the mathematical deductive reasoning abilities of students.

Summary
Matematika memiliki peran penting dalam meningkatkan efisiensi perkembangan teknologi. Hasil penelitian yang dilakukan oleh Ayalon and Even (2008) menyatakan bahwa penalaran deduktif sangat penting dalam pembelajaran matematika, penalaran deduktif sebagai langkah-langkah sistematis untuk menyelesaikan masalah baik dalam matematika atau domain lain. Adapun sintaks metode pembelajaran modeling the way dalam penetian ini mengacu pada sintaks modeling the way yang terdiri dari enam langkah dimulai dengan mencari topik yang menuntun siswa untuk mencoba atau mempraktikkan keterampilan yang baru, membagi siswa ke dalam beberapa kelompok kecil, memberikan waktu kepada siswa untuk meciptakan skenario kerja, berlatih, memberikan kesempatan kepada masing-masing kelompok untuk mendemonstrasikan hasil kerjanya, dan memberikan penjelasan untuk mengklarifikasi (Suprijono, 2010). Berdasarkan permasalahan dan paparan di atas, tujuan dari penelitian ini untuk mendeskripsikan peningkatkan kemampuan penalaran deduktif matematis siswa MA NW Kabar berdasarkan sintaks modeling the way.
