Mathematical creative thinking ability is a critical ability in learning mathematics, especially in solving mathematical problems. This research is a qualitative descriptive study that aims to describe the mathematical creative thinking skills based on the mathematical resilience of grade VII F students of SMP Negeri 1 Banyumas. The research subjects were grouped into 3 categories, namely high, medium, and low mathematical resilience categories. The sampling technique used purposive sampling by taking 3 people each in each category to become respondents. Data collection was done by giving questionnaires, written tests, interviews, and documentation which were carried out online. The data analysis technique was done by reducing the data, presenting the data, and drawing conclusions. The results showed: (1) students in the high mathematical resilience category were able to provide a variety of different solutions, as well as come up with new ideas with systematic and detailed answers, (2) students in the moderate mathematical resilience category were able to provide more than one different solution with systematic answers but not detailed, and (3) students in the low mathematical resilience category can solve mathematical problems with systematic.Keywords: Mathematical Creative Thinking Skills; Mathematical Resilience AbstrakKemampuan berpikir kreatif matematis adalah kemampuan yang penting dalam pembelajaran matematika, terlebih dalam penyelesaian permasalahan matematika. Penelitian ini merupakan penelitian deskriptif kualitatif yang bertujuan untuk mendeskripsikan kemampuan berpikir kreatif matematis berdasarkan pada resiliensi matematis siswa kelas VII F SMP Negeri 1 Banyumas. Subyek penelitian dikelompokkan menjadi 3 kategori, yaitu kategori resiliensi matematis tinggi, sedang, dan rendah. Teknik pengambilan sampel menggunakan purposive sampling dengan mengambil masing –masing 3 orang pada setiap kategori untuk dijadikan responden. Pengumpulan data dilakukan dengan pemberian angket, tes tertulis, wawancara, dan dokumentasi yang dilakukan secara online. Teknik analisis data dilakukan dengan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan: (1) siswa kategori resiliensi matematis tinggi mampu memberikan berbagai penyelesaian berbeda, serta memunculkan ide baru dengan jawaban yang sistematis dan terperinci, (2) siswa kategori resiliensi matematis sedang mampu memberikan lebih dari satu penyelesaian yang berbeda dengan jawaban yang sistematis namun tidak rinci, dan (3) siswa kategori resiliensi matematis rendah mampu menyelesaikan permasalahan matematika dengan jawaban yang sistematis.Kata Kunci: Kemampuan Berpikir Kreatif Matematis; Resiliensi Matematis
Penelitian ini bertujuan untuk memperoleh gambaran kemampuan representasi matematis ditinjau dari peminatan saat jenjang pendidikan menengah mahasiswa semester I Program Studi Pendidikan Matematika FKIP Universitas Muhammadiyah Purwokerto. Jenis penelitian digunakan adalah penelitian deskriptif kualitatif. Prosedur penelitian ini meliputi tiga tahapan utama yaitu: tahap persiapan, tahap pelaksanaan, dan tahap analisis data. Pada tahap persiapan meliputi: (a) mempersiapkan soal tes kemampuan representasi matematis; (b) menentukan subyek penelitian, yaitu dengan cara purposive sampling, sehingga diperoleh 9 Mahasiswa, 3 mahasiswa dari jenjang SMA IPA, 3 mahasiswa dari jenjang SMA IPS, 3 mahasiswa dari jenjang SMK teknik untuk diwawancarai tentang kemampuan representasi matematisnya; dan (c) membuat pedoman wawancara. Tahap pelaksanaan meliputi: (a) mengambil data jenjang pendidikan menengah mahasiswa; (b) melaksanakan tes representasi matematis; dan (c) melaksanakan wawancara. Tahap analisis data meliputi: (a) tahapan reduksi data, (b) penyajian data, dan (c) penyimpulan data. Teknik pengumpulan data yang digunakan oleh peneliti melalui beberapa cara, yaitu: tes dan wawancara. Hasil penelitian menunjukkan bahwa: (a) mahasiswa dengan latar belakang SMA IPA mempunyai kemampuan representasi matematis, (b) mahasiswa dengan latar belakang SMA IPS belum memiliki kemampuan representasi matematis, dan (c) mahasiswa dengan latar belakang SMK sudah memiliki kemampuan representasi matematis, walaupun belum sempurna.
This research aims to identify the error of students’ answers to the quations of descriptive statistics viewed from mathematical communication skill. This is a descriptive research. The subjects of this research are 36 students of class IB. The technique of data collection used in this research is test. Based on the result of the research, it can be concluded that the errors of students’ answers to the quations of descriptive statistics viewed from mathematical communication skill are: (1) the error in presenting diagram appropriate to the objective of 30.56%; (2) the error in presenting data in the frequency distribution table of 27.78%; (3) the error in presenting data from frequency histogram to frequency distribution table of 22.22%; and (4) the inconsistency in writing symbol of 36.11%. Based on the result, it is known that the most errors of the students’ answer viewed from mathematical communication skill are the inconsistency in using the symbols.Keywords: Error identification, Mathematical Communication Skill
