Subjek dari penelitian ini merupakan 3 orang narasumber yang mengerti atau mengetahui tentang ritual adat nimang padi suku dayak kanayat’n. berdasarkan wawancara dan observasi didapat 6 aktivitas etnomatematika yang terkandung dalam ritual adat tersebut yakni; 1) aktivitas membilang/menghitung; 2) aktivitas mengukur; 3) aktivitas mendesain; 4) aktivitas penentuan lokasi; 5) aktivitas bermain; dan 6) aktivitas menjelaskan, serta memuat konsep bangun datar dan bangun ruang.
Penelitian ini bertujuan untuk mengembangkan media pembelajaran PowerPoint yang terintegrasi dengan GeoGebra pada materi transformasi geometri. Penelitian ini menggunakan metode Research and Development dengan model pengembangan ADDIE. Subjek dalam penelitian ini adalah 1 ahli media, 2 ahli materi, dan 31 siswa kelas IX SMP Negeri 4 Sungai Raya. Objek dalam penelitian ini adalah media pembelajaran PowerPoint terintegrasi GeoGebra yang telah dikembangkan. Instrumen pengumpulan data yang digunakan adalah lembar validasi ahli media, lembar validasi ahli materi, dan angket persepsi siswa. Hasil validasi ahli media menunjukkan bahwa media berada pada kategori Sangat Layak dengan persentase 88,33% dan penilaian ahli materi menunjukkan media dari segi materi berada pada kategori Sangat Layak dengan persentase 93%. Pada uji persepsi siswa media berada pada kategori Sangat Layak dengan persentase 94,36%. Sehingga, media pembelajaran PowerPoint terintegrasi GeoGebra yang telah dikembangkan dapat dikatakan layak digunakan sebagai media pembelajaran matematika.
Salah satu yang dapat mempengaruhi terbangunnya keterampilan berfikir kreatif adalah scientific attitudes seseorang. Tujuan penelitian ini adalah (a) Mendeskripsikan profil scientific attitudes mahasiswa Program Studi Pendidikan matematika, (b) Mendeskripsikan kemampuan berpikir kreatif mahasiswa Program Studi Pendidikan matematika, (c) Menguji keterkaitan antara scientific attitudes dan kemampuan berpikir kreatif mahasiswa. Aspek kelancaran, aspek keaslian dan aspek kerincian termasuk kategori tinggi. Sedangkan aspek keluwesan termasuk pada kategori sedang. Bentuk penelitian menggunakan mixed methods dengan status sepadan yaitu menggunakan pendekatan deskriptif kualitatif dan pendekatan kuantitatif. Sedangkan sampel penelitian adalah mahasiswa yang tidak mengulang pada mata kuliah penilaian proses dan hasil pembelajaran matematika tahun ajaran 2022/2023. Pengambilan sampel menggunakan teknik klaster random sampling. Pengujian hipotesis penelitian dengan menggunakan analisis korelasi Kendall Tau. Hasil pengujian hipotesis menunjukkan bahwa terdapat keterkaitan yang erat antara scientific attitudes dengan kemampuan berfikir kreatif mahasiswa pada perkuliahan penilaian proses dan hasil belajar matematika. One that can affect the development of creative thinking skills is a person's scientific attitude. The aims of this study were (a) to describe the scientific attitude profile of students in the Mathematics Education Study Program, (b) to describe the creative thinking skills of students in the Mathematics Education Study Program, (c) to test the relationship between scientific attitudes and students' creative thinking skills. Aspects of fluency, aspects of creativity, and aspects of fact are included in the high category. In comparison, the aspect of flexibility is included in the medium category. This form of research uses mixed methods with commensurate status, namely using a qualitative descriptive approach and a quantitative approach. Meanwhile, the research sample was students who did not repeat the mathematics learning process and results in the 2022/2023 school year assessment course. Sampling using cluster random sampling technique. Testing the research hypothesis using Kendall Tau correlation analysis. The results of hypothesis testing show a close relationship between scientific attitudes and students' creative thinking abilities in the process assessment lectures and mathematics learning outcomes.
This study aimed to examine students' mathematical lateral thinking skills in creative problem-solving, differences in subjects' answers based on the level of their study period, and factors that affect students' lateral thinking skills. The descriptive method was used in the form of an educational survey. The sampling technique used in this research was stratified random sampling. The research subjects were first, third, and fifth-semester students of Mathematics Education at FKIP Tanjungpura University in 2019. The data collection technique used was the "Paper-and-pencil Assessment," with the written test sheet adopted from the Mathematical Lateral Logic Test by Bruce Woodcock. The results showed that students' lateral mathematical thinking skills in creative problem-solving were in the poor category, with an average score of 9.39 out of 25. The results of statistical tests with a value of χ2 indicated that the answers to the subjects were different based on the level of study. The ability to recognize dominant ideas and the polarization of perception of the problem, and the ability to use other ideas are the dominant factors affecting the level of students' mathematical lateral thinking skills in all subject groups. In general, the way of thinking with formal logic or thinking vertically affected students' lateral thinking patterns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
