<![CDATA[Penalaran matematis merupakan salah satu aspek penting yang sangat dibutuhkan peserta didik dalam mempelajari matematika. Berbagai upaya telah dilakukan untuk meningkatkan kemampuan penalaran matematis peserta didik, salah satunya dengan penerapan model pembelajaran Reciprocal Teaching. Penelitian ini merupakan penelitian deskriptif kuantitatif yang bertujuan untuk mengetahui proses pembelajaran dan kemampuan penalaran matematis peserta didik melalui penerapan model pembelajaran Reciprocal Teaching pada materi bangun datar segiempat di kelas VII. Subjek penelitian ini adalah 34 peserta didik kelas VII.5 yang berasal dari SMP Negeri 13 Palembang. Data dikumpulkan menggunakan observasi dan tes. Data yang diperoleh dalam penelitian ini adalah data hasil observasi kegiatan peserta didik pada saat diterapkan model pembelajaran Reciprocal Teaching dan data hasil tes untuk melihat kemampuan penalaran matematis peserta didik setelah diterapkan model pembelajaran Reciprocal Teaching. Analisis data dilakukan secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa (1) keaktifan peserta didik selama diterapkan model pembelajaran Reciprocal Teaching berada pada kategori “sangat aktif” dengan persentase rata-rata 88,71%; (2) kemampuan penalaran matematis peserta didik setelah diterapkan model pembelajaran Reciprocal Teaching berada pada kategori “cukup” dengan rata-rata skor sebesar 67,89.Kata kunci: Pembelajaran Reciprocal Teaching, penalaran matematis, pembelajaran matematika Applying of reciprocal teaching-learning model viewed from students’ mathematical reasoning on the quadrilateral matter AbstractThe mathematical reasoning was one of the important aspects that students need in learning mathematics. Various efforts have been made to improve students’ mathematical reasoning skills, one of which was the application of the Reciprocal Teaching learning model. This research was a quantitative descriptive research that aims to explain the process of learning implementation and student’s mathematical reasoning ability by using the Reciprocal Teaching learning model on the quadrilateral matter in class VII. The subjects of this research were 34 students of class VII.5 from SMP (Junior High School) Negeri 13 Palembang, South Sumatera, Indonesia. Data were collected using observations and tests. The data obtained in this research were the observation data of students activities when applied the Reciprocal Teaching learning model and the test results data to see students’ mathematical reasoning abilities after applying the Reciprocal Teaching learning model. The results of research showed that (1) student activity during applying the Reciprocal Teaching learning model was in the “very active” category with an average percentage of 88.71%; (2) students’ mathematical reasoning abilities after applying the Reciprocal Teaching learning model was in the “enough” category with an average score of 67.89.]]>
