Abstract

Mathematical critical thinking skills have so far shown unsatisfactory results, so media or learning resources such as worksheets are needed to complete them. In addition, concepts of scientific learning such as Niteni, Nirokke, and Nambahi activities have not provided opportunities for students to think critically. For this reason, this study aims to obtain valid and practical relations and function worksheets based on tri-n. The research stages used are defining, designing, and developing. These three stages are part of the development research with 4D. At the defining stage, data collection techniques use documentation to make the data analysis qualitative. At the design stage, data collection techniques use observation to make the data analysis qualitative descriptive. In the developing stage, the data collection technique uses a questionnaire, so the data analysis is quantitative. The results showed that the relations and function worksheets based on Tri-N had a V-Aiken index of more than 0.83, and some students responded well to this worksheet. Apart from that, the mathematics material in this Student Worksheet uses the Tri-N stages, namely Niteni, Nirokke, and Nambahi. Based on this, it can be concluded that the Tri-N-based Student Worksheet on Relations and Functions is a valid and practical result of development. For this reason, this worksheet can be used to improve students' critical thinking skills. Kemampuan berpikir kritis matematis siswa selama ini menunjukkan hasil yang belum memuaskan, sehingga dibutuhkan media atau sumber belajar sepert worksheet untuk menyelesaikannya. Selain itu, konsep pembelajaran saintifik seperti kegiatan Niteni, Nirokke, Nambahi belum memberikan kesempatan kepada siswa untuk berpikir kristis. Untuk itu penelitian ini bertujuan untuk memperoleh Lembar Kerja Siswa Relasi dan Fungsi berbasis Tri-N yang valid dan praktis. Tahapan penelitian yang digunakan adalah mendefinisi, mendesain, dan mengembangkan. Ketiga tahapan ini merupakan bagian dari penelitian pengembangan tipe 4D. pada tahap mendefinisi, Teknik pengumpulan data menggunakan dokumentasi, sehingga analisis data yang digunakan bersifat kualitatif. Pada tahap mendesain, Teknik pengumpulan data menggunakan observasi, sehingga analisis data yang digunakan bersifat kualitatif deskriptif. Tahap mengembangkan, Teknik pengumpulan data menggunakan angket, sehingga analisis data yang yang digunakan bersifat kuantitatif. Hasil penelitian diperoleh bahwa Lembar Kerja Siswa Relasi dan Fungsi memiliki indeks V Aiken lebih dari 0,83, dan sebagian siswa memberikan respon sangat baik terhadap prototipe worksheet ini. Selain itu, materi matematika yang ada pada Lembar Kerja Siswa ini menggunaan tahapan Tri-N, yaitu Niteni, Nirokke, dan Nambahi. Berdasarkan hal tersebut dapat disimpulkan bahwa Lembar Kerja Siswa Relasi dan Fungsi berbasis Tri-N hasil pengembangan yang valid dan praktis. Untuk itu dimungkinkan worksheet ini digunakan sebagai salah satu cara untuk meningkatkan kemampuan beprikir kritis siswa.

Abstract

The background of this research is that student learning outcomes in analytical geometry lecture during the transition from pandemic to Covid-19 endemic are still low, which is due to a lack of student interest in learning, and they are still accustomed to online learning, thus having an impact on their low problem-solving skills and mathematical disposition. This research aims to determine to what extent the implementation of ethnomathematics and the Mozart effect can improve students' problem-solving skills and mathematical disposition in analytical geometry lecture during the transition from pandemic to endemic COVID-19, so the research is important to do. The implementation of ethnomathematics and the Mozart effect in mathematics learning is unique because it is a combination of learning approaches that have never been used before in Indonesia and other countries. The research method used was a quasi-experimental non-equivalent control group design because this research was experimental and sample determination was not carried out randomly, but using purposive sampling technique on the second-semester students of the mathematics undergraduate program, Faculty of Mathematics and Natural Sciences, Universitas Padjadjaran. The instruments used in this study were problem-solving skills test, mathematical disposition scale, and students’ attitude questionnaire toward learning with the implementation of ethnomathematics and the Mozart effect. The results showed that: (1) problem-solving skills of students who received learning by implementing ethnomathematics and the Mozart effect are better than students who achieved direct instruction; (2) mathematical disposition of students who received learning by implementing ethnomathematics and the Mozart effect is better than students who achieved direct instruction; and (3) students are interested and motivated to learn mathematics by implementing ethnomathematics and the Mozart effect. This research concludes that the implementation of ethnomathematics and the Mozart effect can improve students' problem-solving skills and mathematical disposition in analytical geometry lecture during the transition period from the pandemic to endemic COVID-19. It can be seen from good average post test scores achieved by students.
