Abstract

Abstract The aim of this study is to describe the effectiveness of applying cooperative learning of jigsaw type on students’ mathematical communication ability on the topic statistics at the eleventh grade students of SMA Negeri 2 Padang Bolak. This research was conducted by applying experimental (one group pre test post test design) with 47 students as the sample and they were taken by using total sampling technique . Observation and test were used in collecting the data. Based on descriptive analysis, it was found that: (a) the average of applying jigsaw type was 3.56 (very good category) and (b) the average of students’ mathematical communication ability on the topic statistics before using jigsaw type was 58.81 (fair category) and after using jigsaw type was81.13 (very good category). Furthermore, based on inferential statistics by using pair sample ttest, and help SPSS version 16, the result showed the significant value was less than 0.05 (0.000<0.05). It means, applying cooperative learning of jigsaw type on students’ mathematical communication ability on the topic statistics at the eleventh grade students of SMA Negeri 2 Padang Bolak. Keywords: cooperative learning of jigsaw type, mathematical communication ability

Abstract

Abstract Penelitian ini bertujuan untuk mengetahui tentang efektivitas Pendekatan Pendidikan Matematika Realistik terhadap Kemampuan Berpikir Kreatif Matematis Siswa di SMA Negeri 1 Portibi. Mengajarkan dan mengembangkan kemampuan berpikir kreatif matematis siswa sangatlah penting dan jangan dianggap hal sepele. Jenis penelitian eksperimen, dengan populasi seluruh siswa kelas X sebanyak 142 orang. Sampel penelitian ini yaitu siswa kelas X IPA-3 berjumlah 24 orang dengan menggunakan tekhnik Cluster Random Sampling. Pengumpulan data menggunakan observasi dan tes yang sebelumnya sudah divalidasi. Hasil penelitian menunjukkan gambaran tentang pendekatan pendidikan matematika realistik dengan nilai rata-rata 3,56 dengan kategori “Sangat Baik”. Gambaran kemampuan berpikir kreatif matematis siswa sebelum menerapkan pendekatan pendidikan matematika realistik diperoleh nilai rata-rata 59,23 dengan kategori Kurang”. Sedangkan untuk kemampuan berpikir kreatif matematis siswa sesudah menerapkan pendekatan pendidikan matematika realistik diperoleh nilai rata-rata 83,47 dengan kategori “Sangat Baik”, dengan kata lain terjadi peningkatan penerapan pendidikan matematika realistik terhadap kemampuan berpikir kreatif matematis siswa. Artinya, “Pendekatan pendidikan matematika realistik efektif dalam meningkatkan kemampuan berpikir kreatif matematis siswa di SMA Negeri 1 Portibi”. Kata-kata kunci: Pendekatan Pendidikan Matematika Realistik dan Kemampuan Berpikir Kreatif Matematis siswa
