Abstract

Guru harus mengembangkan soal berpikir kreatif matematis sesuai dengan dominasi otak siswa untuk mengoptimalkan fungsi kedua belahan otak secara seimbang, sehingga dapat menciptakan pembelajaran yang optimal. Tujuan penelitian ini adalah untuk mengetahui bagaimana siswa menyelesaikan soal berpikir kreatif matematis ditinjau dari dominasi otak. Metode penelitian yang digunakan adalah kualitatif dengan pendekatan deskriptif eksploratif. Instrumen yang digunakan adalah soal berpikir kreatif matematis, tes dominasi otak, dan wawancara tidak terstruktur. Hasil penelitian sebagai berikut: siswa dominasi otak kiri menyelesaikan soal berpikir kreatif matematis menggunakan karakteristik dari fungsi belahan otak kiri yaitu berpikir konvergen, analisis, penilaian analitik, berurutan dan teratur, sedangkan penggunaan karakteristik fungsi belahan otak kanan yaitu memori baru proses dan sistem membaca seluruh bahasa; siswa dominasi otak seimbang menggunakan karakteristik fungsi belahan otak kiri yaitu melakukan proses lalu memori, sistem membaca fenotik, respon verbal, berurutan dan teratur, sedangkan penggunaan karakteristik belahan otak kanan adalah berpikir holistik dan berpikir sintesis; dan siswa dominasi otak kanan menggunakan karakteristik dari fungsi belahan otak kanan yaitu sistem membaca seluruh bahasa, memori lalu proses, respon non verbal, berpikir holistik, berpikir sintesis, dan bersifat acak.

Abstract

Tujuan penelitian ini adalah mendapatkan gambaran proses berpikir kreatif matematis siswa dalam memecahkan masalah matematika berdasarkan tahapan Wallas yang ditinjau dari dominasi otak seimbang. Metode penelitian yang digunakan adalah kualitatif dengan pendekatan deskriptif – eksploratif. Teknik pengumpulan data menggunakan tes berpikir kreatif matematis, tes dominasi otak, dan wawancara tidak terstruktur. Instrumen utama penelitian ini adalah peneliti sendiri dengan bantuan instrumen lainnya berupa soal tes berpikir kreatif matematis dan tes dominasi otak. Analisis data dilakukan dengan langkah-langkah: reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa: siswa berdominasi otak seimbang dapat memecahkan masalah matematis melalui tahapan Wallas. Tahap persiapan siswa membaca soal kemudian bertanya kepada siswa lainnya. Tahap persiapan mampu dilalui dengan berpikir konvergen dan respon berupa respon verbal. Tahap inkubasi siswa merenung untuk mencari ide atau gagasan dan tahap iluminasi siswa menuliskan konsep yang akan digunakan. Tahap inkubasi dan tahap iluminasi mampu dilalui dengan berpikir divergen. Tahap verifikasi siswa menyelesaikan soal dengan dua cara yaitu menggunakan volume kubus dan volume balok. Tahap verifikasi mampu dilalui dengan berpikir konvergen dan respon verbal yang merupakan ciri belahan otak kiri, serta berpikir divergen, berpikir sintesis, dan berpikir holistik yang merupakan belahan otak kanan. Siswa mampu menyelesaikan masalah dengan merespon secara verbal ketika mendapatkan kendala, sedangkan proses pengerjaan dihitung dengan berpikir sintesis dan berpikir holistik. siswa juga melakukan proses berpikir konvergen dan berpikir divergen dalam memecahkan masalah. Siswa melakukan proses berpikir konvergen dan berpikir divergen secara bergantian sehingga jumlah berpikir konvergen dan berpikir divergen dilakukan dengan jumlah yang sama.

Abstract

Convergent and divergent thinking play an essential role in a person’s creative thinking process to solve problems, which highlights the significance of this research. Aside from that, these two types of thinking are related to the function of the brain’s hemispheres that will affect a person’s perspective in processing information. This research aims to get a view of convergent and divergent thinking in the mathematical creative thinking process in terms of brain dominance. The research was conducted using qualitative method with an exploratory descriptive approach. The instruments used are mathematical creative thinking test, brain dominance tests, and unstructured interviews. The research revealed that left-brain dominant students in the creative thinking process are more prominent in convergent thinking; the balance dominant students in the creative thinking process are balanced in divergent and convergent thinking, while right-brain dominant students in the creative thinking process are more adept in divergent thinking.

Abstract

Differences in students' resilience levels are very important, especially when facing difficulties in solving problems. The relationship between brain dominance and mathematical resilience, as well as the different ways of thinking of the two hemispheres of the brain, requires research on mathematical resilience based on brain dominance. In addition, research on mathematical resilienci based on brain dominance has not been conducted. The purpose of this study was to obtain a picture of mathematical resilience in terms of brain dominance. The research method used was qualitative with a descriptive exploratory approach. The instruments used were a mathematical resilience questionnaire, a brain dominance test, and an unstructured interview. The subject of this study were 3 subjects who met the criteria consisting of 1 subject with left brain dominance, 1 subject with balanced brain dominance, and 1 subject with right brain dominance. The results of the mathematical resilience study based on brain dominance were that left brain dominance students met all the measured indicators, balanced brain dominance students met 4 measured aspects and 2 aspects were not met, and right brain dominance students met all measured indicators.

Abstract

This study aims to develop a Project Based Learning (PjBL)-based teaching module to enhance students’ critical and creative thinking skills on the topic of the Pythagorean Theorem. The research employed a Research and Development (R&D) approach using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The module was validated by five experts, resulting a score of 0.71, categorized as very valid. The module was tested on 38 eighth-grade students at SMP Negeri 11 Cirebon. The effectiveness test showed a significant improvement in students’ critical and creative thinking abilities, with N-Gain scores of 0.56 and 0.57 respectively, both categorized as moderately effective. The Wilcoxon test showed a significance value of 0.000 for both skills, indicating a significant difference between pretest and posttest scores. Additionally, student responses to the module were highly positive, with an average score of 85.91%. Based on these results, the developed PjBL-based teaching module is considered feasible and effective for enhancing higher-order thinking skills in mathematics learning.
