Abstract

ABSTRACT The aim of this study is to describe the effectiveness using expository strategy by helping macromedia flash 8 on students’ mathematical problem solving ability on topic of opportunity at the eleventh grade students of SMA Negeri 1Panyabungan Utara. This research was conducted by applying experimental (one group pre test post test design) with 24 students as the sample and they were taken by using cluster sampling technique from 49 students. Observation and test were used in collecting the data. Based on descriptive analysis, it was found: (a) the average of using expository strategy by helping macromedia flash 8 was 3.6 (very good category), (b) the average of students’ mathematical problem solving ability on topic of opportunity before using expository strategy by helping macromedia flash 8 was 53.12 (fair category) and after using expository strategy by helping macromedia flash 8 was 74.50 (good category) and (c) classical completeness showed 75% (effective category). It means, using expository strategy by helping macromedia flash 8 is effective on students’ mathematical problem solving ability on the topic opportunity at the eleventh grade students of SMA Negeri 1Panyabungan Utara. Keywords: effectiveness, strategy, expository, macromedia flash 8, problem solving

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

Abstract

abstract The aims of this study is to describe the effectiveness of using Realistic Mathematical Education (RME) approach on students’ mathematical problem solving ability on the topic of the system of linier equation two variables at the tenth grade students of SMK Negeri 1Batang Angkola. This research was conducted by applying experimental method with 30 students as the sample and they were taken by using simple random sample technique from 130 students. Test and observation were used in collecting the data. Based on descriptive analysis, it was found (a) the average of using RME approach was 2.8 (good category) and (b) the average of students’ mathematic problem solving ability on the topic of the system of linier equation two variables before using RME approach was 49.9 (poor category) and after using RME approach was 85.9 (very good category). Furthermore, by using pair sample ttest and help SPSS version 17, the result showed the significant value was less than 0.05 (0.000<0.05). It means, RME approach was effective used on students’ mathematic problem solving ability on the topic of the system of linier equation two variables at the tenth grade students of SMK Negeri 1Batang Angkola. Keywords: RME approach, mathematical problem solving ability, the system of linier equation two variables
