Pemahaman Konsep Mahasiswa Tentang Ring Pada Mata Kuliah Struktur Aljabar 2 Ditinjau Dari Pemikiran Kreatif Pada Siswa Kelompok Atas

Abstract

This research is intended to describe the students concept of the ring in the course of algebra structure 2 in terms of creative thinking in upper students. This research is included in this type of qualitative research. The subject of the study is a mathematics student who has taken the course of Structure Algebra 2 (Ring Theory). The subjects in this study are three students who have high math skills. Instrument used in research 1) Test of Concept of Ring Concept (TPKR), 2) Interview Guidelines, 3) Creative Thinking Rubric, 4) Recording Equipment, 5) Documentation. Based on the results of the study and discussion, the findings involving the students' concept of the ring in the course of algebraic structure 2 in the upper sstudent can solve the problem in terms of explaining the associative nature, explaining the nature of the identity element, explaining the nature of each element having a good inverse. However, I can not only use one solution only, but it is less diverging and able to find other solutions. At the student level still not able to meet the original indicators in creative thinking

Analisis Kesulitan Mahasiswa Dalam Menyelesaikan Soal Pemahaman Matematis Pada Mata Kuliah Teori Peluang

“…Menurut Rismawati & Hutagol (2018) menjelaskan bahwa saat mahasiswa mengetahui konsep, mahasiswa dapat menentukan prinsip serta topik pembelajaran memakai daya pikir personal deskripsi untuk memberi mahasiswa miliki pengaturan kata berbeda tetapi mempunyai tujuan serupa. Sejalan dengan hal tersebut, Rubowo et al (2017) juga menjelaskan bahwa penguasaan terhadap suatu konsep matematika yang rumit dan kompleks memerlukan suatu kecermatan atau ketelitian, baik itu cermat dalam memahami makna simbol pada suatu konsep, cermat dalam memahami konsep-konsep sebelumnya, dan cermat dalam mengaitkan konsep sebelumnya dengan konsep yang sedang dipelajari. Hal ini juga sejalan dengan beberapa hasil penelitian yang menemukan fakta bahwa masih banyak pemahaman konsep matematik mahasiswa yang kurang dan mengalami kesulitan serta kesalahan dalam mempelajari suatu konsep (Gusmania & Agustyaningrum, 2020;Hanifah & Abadi, 2018;Nila, 2016;Purwaningrum & Bintoro, 2018;Rosyidah et al, 2021;Suraji et al, 2018).…”

The Coherence of Group Scheme of the High Initial Ability Students Based on Cognitive Style

“…As an abstract subject, group theory is open to misconceptions at the more general levels of proof and logical reasoning (Alcock, et al, 2015). The characteristic of group theory emphasizes on the abstract thinking aspect (Putra & Kristanto, 2017). According to Wasserman (2017), the abstractness of group theory is useful for teachers because it helps them understand and interpret the mathematics they are going to teach.…”
