Pemahaman Konsep Mahasiswa Semester Satu pada Mata Kuliah Trigonometri

Abstract

Trigonometry, a discipline in mathematics, is often misunderstood by mathematics learners. To understand Trigonometry, students should start learning from understanding Mathematical concepts. Therefore, this study aims to analyze students' understanding of concepts in the Trigonometry course. This research is a qualitative descriptive study of the first semester students' conceptual understanding of the mathematics education study program at a university in Malang City. The data collected in this study consisted of the subject's work and transcripts of interviews. The instrument used in this study consisted of 6 questions about understanding the concept of trigonometric material. Analysis of the subject's work results is carried out to find out the right or wrong answers. Meanwhile, the interview transcripts were analyzed by coding to determine the factors that support conceptual understanding. The results showed that students with good conceptual understanding could solve trigonometric problems, while students with less understanding of concepts had difficulty solving trigonometric problems. The results of this study also found aspects that influence (encourage and inhibit) students in understanding the concept of trigonometry. Furthermore, this research is expected to contribute to trigonometry subjects' learning based on indicators of conceptual understanding in the Trigonometry course.

Prospective Teachers Representations in Problem Solving of Special Angle Trigonometry Functions Based on the Level of Ability

“…Previous research results also showed that prospective teachers still experienced errors in drawing trigonometric function graphs (Jaelani, 2017;Setiawan, 2021). The results of other studies also show that prospective teacher's understanding of concepts in trigonometric material is still lacking (Mustangin & Setiawan, 2021;Nabie et al, 2018;Tuna, 2013). However, what is new from the results of this study is that all prospective teachers with low abilities can use the triangle representation correctly so that they can successfully solve the problem of special angle trigonometric functions.…”

“…The results showed that students who were able to prove had relevant basic knowledge (Setiawan, 2020a). The results of other studies show that students and students with low abilities often experience errors in solving problems (Mustangin & Setiawan, 2021;Setiawan, 2020bSetiawan, , 2020cSetiawan, , 2021Setiawan et al, 2020). This means that representation can be influenced by the abilities students have in understanding the material or solving math problems.…”

“…This can be seen from the results of research that show that prospective teachers experience errors in drawing cosine function graphs, errors in applying trigonometric comparisons, and errors in writing down trigonometric reduction identities to determine the value of the trigonometric function for special angles (Setiawan, 2021). The results also show that prospective teachers consider trigonometric material to be difficult and abstract (Nabie et al, 2018), so that conceptual understanding of prospective teachers is low in learning trigonometric material (Mustangin & Setiawan, 2021). This error is usually solved by introducing the prospective teachers to triangular trigonometry rather than circular trigonometry.…”

Workshop Penulisan Artikel Ilmiah untuk Publikasi Jurnal Nasional Terakreditasi Sinta di IAIN Kediri

“…Kesulitan ini dapat dikurangi dengan memberikan pemahaman dalam penulisan artikel ilmiah berdasarkan komponen artikel ilmiah. Hasil penelitian menunjukkan bahwa pemahaman terhadap komponen dari suatu materi dapat menyebabkan keberhasilan dalam belajar (Mustangin & Setiawan, 2021;Setiawan, 2020cSetiawan, , 2020dSetiawan, , 2020a dan sebaliknya kurangnya pemahaman terhadap komponen materi dapat menyebabkan kesalahan (Setiawan, 2021c(Setiawan, , 2021aSetiawan & Mustangin, 2020). Oleh sebab itu, penyampaian materi tentang penulisan karya ilmiah ini dilakukan sesuai komponen artikel ilmiah.…”

Analysis of Error in Determining the Distance Between Two Points in the Cartesian Plane in the First Semester Students

“…Trigonometry is a fundamental topic taught in high schools and colleges (Nejad, 2016). Trigonometry is a prerequisite course for calculus, vector analysis, and differential equations (Mustangin & Setiawan, 2021;Setiawan, 2021aSetiawan, , 2021b. Trigonometry is also taught at the high school level.…”
