TINGKAT KEMAMPUAN BERPIKIR KREATIF SISWA SMP DALAM MENYELESAIKAN MATHEMATICAL MODELLING PROBLEM DITINJAU DARI SELF EFFICACY

LEVEL OF CREATIVE THINKING ABILITY OF JUNIOR HIGH SCHOOL STUDENTS IN SOLVING MATHEMATICAL MODELLING PROBLEM IN TERMS OF SELF-EFFICACY

Kemampuan berpikir kreatif seseorang bertingkat dan dapat ditingkatkan dengan memahami kemampuan berpikir kreatif serta faktor-faktornya seperti self efficacy. Tujuan penelitian ini yaitu mendeskripsikan tingkat kemampuan berpikir kreatif siswa kelas IX dengan self efficacy tinggi, sedang, dan rendah dalam menyelesaikan mathematical modelling problem. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Untuk subjek penelitian, peneliti memilih tiga siswa kelas IX di SMPN 4 Pare dengan tingkat self efficacy berbeda (tinggi, sedang, rendah), kemampuan matematika tinggi, dan berjenis kelamin sama. Peneliti menggunakan angket self efficacy, tes kemampuan matematika, mathematical modelling problem, dan wawancara untuk mengumpulkan data. Data berupa hasil tes dianalisis berdasarkan tingkat kemampuan berpikir kreatif Siswono dan wawancara lanjutan. Hasil penelitian menunjukkan pada aspek kelancaran, siswa self efficacy tinggi dapat memberikan tiga jawaban dengan tepat, siswa self efficacy sedang dapat memberikan dua jawaban tepat, dan siswa self efficacy rendah hanya memberikan satu jawaban tepat. Aspek keluwesan, ketiga subjek dapat memberikan penyelesaian menggunakan cara berbeda. Aspek kebaruan, siswa self efficacy tinggi dapat memberikan dua solusi baru sedangkan siswa self efficacy sedang dan siswa self efficacy rendah menghasilkan solusi umum. Berdasarkan hal tersebut, siswa self efficacy tinggi tergolong tingkat kemampuan berpikir kreatif 4 (sangat kreatif), siswa self efficacy sedang tergolong tingkat kemampuan berpikir kreatif 3 (kreatif), dan siswa self efficacy rendah tergolong tingkat kemampuan berpikir kreatif 2 (cukup kreatif).

A person's creative thinking ability is graded and can be improved by understanding creative thinking ability and its factors such as self efficacy. The purpose of this study is to describe the level of creative thinking ability of ninth grade students with high, medium, and low self efficacy in solving mathematical modelling problems. This research uses a qualitative approach with descriptive research type. For the research subject, the researcher chose three ninth grade students at Junior High School 4 Pare with different levels of self efficacy (high, medium, low), high mathematical ability, and the same gender. The researcher used self efficacy questionnaire, mathematical ability test, mathematical modeling problem, and interview to collect data. Data in the form of test results were analyzed based on Siswono's level of creative thinking ability and follow-up interviews. The results showed that in the fluency aspect, high self efficacy students could give three correct answers, moderate self efficacy students could give two correct answers, and low self efficacy students only gave one correct answer. The flexibility aspect, the three subjects can provide solutions using different ways. The novelty aspect, high self efficacy students can provide two new solutions while moderate self efficacy students and low self efficacy students produce common solutions. Based on this, high self efficacy students belong to creative thinking ability level 4 (very creative), moderate self efficacy students belong to creative thinking ability level 3 (creative), and low self efficacy students belong to creative thinking ability level 2 (quite creative).
