Abstract

Kemampuan matematis adalah kemampuan untuk menghadapi permasalahan, baik dalam matematika maupun kehidupan nyata. Kemampuan matematis terdiri dari Penalaran matematis, komunikasi matematis, pemecahan masalah, pemahaman konsep, pemahaman matematis, berpikir kreatif dan berpikir kritis. Dalam aspek pemecahan masalah matematika diperlukan pemikiran-pemikiran kreatif dalam merumuskan dan menyelesaikan model atau perencanaan pemecahan masalah. Salah satu materi yang dapat mendorong siswa untuk berpikir kreatif yaitu SPLDV, siswa dituntut untuk menuangkan ide-ide kreatifnya, karena penyelesaian soal SPLDV banyak cara metode yang dapatĀ  digunakan. Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kreatif matematis terhadap siswa MTs Kelas VIII melalui tugas Problem Posing pada materi SPLDV. Sedangkan yang menjadi sampel dalam penelitian ini adalah 6 orang siswa yang terdiri dari 2 orang siswa berkemampuan tinggi, 2 orang siswa berkemampuan sedang, dan 2 orang berkemampuan rendah. Segala sesuatu yang akan diukur diantaranya tes kemampuan berpikir kreatif matematis yang berdasarkan indikator-indikatornya sebanyak 5 soal berbentuk essay. Berdasarkan hasil analisa data diperoleh pola Persentase penyelesaian masalah seluruh subjek penelitian tiap indikator kemampuan berpikir kreatif matematik yaitu : (1) kelancaran (Fluency) 64,63% ; (2) Kelenturan (Flexibility) 44,20% ; (3) Keaslian/ orisinalitas (Originality) 48,58% ; (4) Elaborasi (Elaboration) 62,50%.

Abstract

This study aims to determine the level of communication skills and mathematical creative thinking of junior high school students through tests of straight-line equation questions, and analyze the difficulties of students in solving problems in the matter of straight-line equations. The population in the study were all eighth grade students of Pasundan 1 Junior High School 1 Cimahi with a sample of 9 students in class VIII I who were taken using the proportionate stratified random sampling technique that is by taking samples from each strata proportionally randomly with the provisions of each of the 3 high-ability students , 3 students with moderate ability and 3 low-ability students. The research data was collected through a test of mathematical communication skills based on the indicators of 4 essay questions. The results showed students' mathematical communication skills of 34.4% included in the less category, while for creative thinking ability was 41% including sufficient categories. Based on the answer analysis students have been able to identify elements that are known and asked and stated them in mathematical symbols, able to identify the links between elements / data that are known and asked, only students have not been able to complete mathematical models and determine relevant solutions. Based on the results of the average questionnaire shows that students' self-confidence in mathematics learning can be categorized as being. These results are directly proportional to the results of tests of low mathematical communication skills and creative thinking abilities that are categorized sufficient.
