Abstract

AbstrakLimit trigonometri menjadi salah satu materi penting pada mata kuliah Kalkulus. Namun mahasiswa mengakui bahwa sub-bab materi ini sangatlah sulit, sekalipun mereka sudah mempelajarinya di bangku sekolah menengah. Solusi yang ditawarkan adalah menganalisis kesulitan apa saja yang dialami mahasiswa. Oleh karena itu, tujuan penelitian ini adalah mendeskripsikan kesulitan-kesulitan mahasiswa dalam menyelesaikan soal limit trigonometri dan penyebab kesulitannya. Metode penelitian yang digunakan dalam penelitian ini adalah penelitian deskriptif kualitatif. Subjek penelitian yaitu mahasiswa pendidikan matematika yang berjumlah 30 mahasiswa, kemudian dianalisis tiga jawaban mahasiswa yang mewakili kesalahan yang paling banyak dilakukan oleh mahasiswa. Instrumen penelitian yang digunakan adalah soal tes sebanyak dua nomor tentang limit trigonometri. Hasil penelitian menunjukkan bahwa kesalahan yang ditemui pada penelitian ini adalah kesalahan konsep, kesalahan operasi dan kesalahan prinsip.   Analysis of the Difficulties of Mathematics Education Students in Solving Trigonometric Limit Problems AbstractLimit trigonometry is one of the important materials in Calculus courses.

Abstract

Pendidikan di era 4.0 memberikan dampak dalam proses pembelajaran setelah sebelumnya hanya memanfaatkan media seadanya saja dari pengajar, dimana dengan perkembangan teknologi harus dapat memanfaatkan fasilitas internet dan dapat menunjang kompetensi mahasiswa secara teori dan praktek. Salah satu cara yang dapat dilakukan adalah dengan mengembangkan media berbahasa pemrograman open-source dengan penerapan computational thinking. Oleh karena itu tujuan dari penelitian ini adalah untuk membuat media berbahasa pemrograman open-source dengan penerapan computational thinking dan untuk mengetahui efektivitas dari media yang dikembangkan terhadap hasil belajar mahasiswa. Metode yang digunakan dalam penelitian ini adalah metode R & D serta penelitian eksperimental dengan subjek penelitian adalah mahasiswa Pendidikan Matematika Universitas Timor yang memrogram matakuliah Kalkulus Lanjut T.A. 2021/2022. Instrumen yang digunakan adalah lembar validasi ahli materi dan ahli media, angket respon mahasiswa, serta soal pre-test dan post-test. Hasil penelitian menunjukkan bahwa media yang dikembangkan mendapatkan penilaian “sangat baik” dari ahli materi dan ahli media serta dari mahasiswa. Sebagai tambahan, terdapat peningkatan hasil tes mahasiswa sebesar 91,36 setelah diberikan perlakuan meskipun mahasiswa cenderung kurang mendapatkan penekanan pada tahap persevering. Kesimpulannya, media yang dikembangkan efektif dalam meningkatkan hasil belajar mahasiswa.

Abstract

Mathematics is a form of culture inherent in all aspects of society's life. In the cultural practices of certain communities, mathematical concepts are involved. There is an intersection between culture and mathematics. Therefore, this research is conducted to explore the mathematical concepts used by traders. This study was conducted at the Niki-Niki Traditional Market. The research subjects consist of 6 individuals, with 2 betel nut sellers, 2 chili pepper sellers, and 2 woven fabric sellers. The data in this study are primary data collected through observation, interviews, and documentation techniques. Data analysis employs the techniques of ethnographic research data analysis, including domain analysis, taxonomic analysis, componential analysis, and cultural theme analysis. The results of the research indicate that there are mathematical concepts of plane geometry and integers in the activities of traders. Concepts of plane geometry include points, rectangles, circles, rhombuses, straight lines, curved lines, and fractal geometry. Meanwhile, mathematical concepts related to integers include sets, counting, addition, subtraction, division, and multiplication.

Abstract

Literacy Numeracy is currently one of the topics in learning mathematics. A person is said to have Numerical Literacy Ability to count, distinguish and process various data symbols, and perform basic mathematical operations to fix the problem. However, the problem that is always faced by students today is the lack of understanding of the basic concepts of mathematics, one of which is integer arithmetic operations, so it won't be easy to understand more abstract mathematical concepts. The low numeracy literacy ability is due to the learning process not applying the suitable model or media. Therefore, it is necessary to have appropriate learning media so that students understand concepts well and can improve Numerical Literacy skills. One of the proper media or teaching aids for learning integer arithmetic operations is Koin Muatan, made with paper as a base material that symbolizes positive and negative charges. The type of research used was experimental research, a one-group pretest-posttest design pre-experimental design on 21 SD GMIT 4 Kefamenanu students. Data collection techniques were observation, tests and documentation. At the same time, the data analysis technique used is descriptive statistical analysis, inferential analysis and N-Gain analysis. The t-test results are used to test the average value before and after being given treatment and whether there is a significant effect. Based on the results of the tests performed, the average pretest and posttest values were 43.51 and 70.79. An N-Gain test was carried out to determine the large increase in numeracy literacy skills so that an N-Gain value of 0.45 was included in the moderate category. This result proves an increase in numeracy literacy skills after students are given the learning treatment using the Koin Muatan teaching aids at SD GMIT 4 Kefamenanu.
