Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kreatif matematis siswa Sekolah Menengah Atas pada materi Sistem Persamaan Linier Dua Variabel secara keseluruhan kemampuan siswa, berdasarkan kategori kemampuan, dan berdasarkan kemampuan setiap indikator kemampuan berpikir kreatif matematis. Subjek penelitian adalah siswa dari kelas X sebanyak 30 siswa pada salah satu Sekolah Menengah Atas di kota Garut, Jawa Barat-Indonesia. Penelitian ini merupakan penelitian deskriptif kualitatif dengan menggunakan teknik purposive sampling. Instrumen penelitian menggunakan tes kemampuan berpikir kreatif dan wawancara. Indikator kemampuan berpikir kreatif yang diukur meliputi: fluency (berpikir lancar); flexibility (berpikir luwes); originality (keaslian); elaboration (berpikir elaborasi). Hasil penelitian menunjukkan: (1) secara keseluruhan kemampuan berpikir kreatif sebesar 60,65% termasuk kategori cukup; (2) berdasarkan kategori kemampuan berpikir kreatif matematis menunjukkan bahwa 86,25% siswa berkemampuan sangat baik, 73,92% kategori baik, 53,31% kategori cukup, dan 35,00% kategori kurang; (3) kemampuan berpikir kreatif berdasarkan indikator a) Fluency siswa sebesar 56,67% (kategori cukup), b) Flexibility siswa 26,67% (kategori kurang), c) Originality siswa sebesar 40,00% (kategori cukup), dan d) Elaboration siswa sebesar 46,67% (kategori cukup). Hal ini menunjukkan bahwa kemampuan berpikir kreatif matematis siswa masih belum optimal dan memerlukan perhatian bagi pendidikan dan pemangku kebijakan pendidikan.

Analyzing mathematical creative thinking skills of senior high school students in Algebra

Abstract

This study aims to analyze the mathematical creative thinking skills of senior high school students in solving two-variable linear equation systems problems generally, based on the ability category, and on the ability of each indicator of the mathematical creative thinking ability. The research subjects are 30 grade X students of one of the high schools in the city of Garut, West Java-Indonesia. This research is a qualitative descriptive study employed the purposive sampling technique. The research instrument includes a creative thinking skills test and interview guide. The indicators of creative thinking abilities that are measured include fluency, flexibility, originality, elaboration. The results show: (1) the ability to think creatively has a percentage of 60.65% (sufficient category); (2) the mathematical creative thinking ability: 86.25% in very good category, 73.92% in good category, 53.31% in moderate category (53.31%), and 35.00% in an insufficient category; (3) the ability to think creatively based on indicators shows a) fluency has a percentage of 56.67% (sufficient category, b) flexibility has a percentage of 26.67% (poor category), c) originality has a percentage of 40.00 % (sufficient category), and d) elaboration has a percentage of 46.67% (sufficient category). This implies that teachers and policymakers need to pay attention to students' mathematical creative thinking skills.
