MAPPING UNDERSTANDING THE CONCEPT OF COMPLEX NUMBERS OF TADRIS MATHEMATICS STUDENTS OF UIN K.H. ABDURRAHMAN WAHID PEKALONGAN

Abstract

Basic mathematical concepts in complex numbers are important in understanding further what complex number material is in complex analysis courses. The aim of this research is to map the understanding of mathematics students at UIN K.H. Abdurrahman Wahid Pekalongan on the concept of complex numbers. This research adopts a qualitative approach through descriptive analysis. The subjects of this research were 10 Tadris mathematics students taking complex analysis courses in the 2023/2024 academic year. The data collection technique uses a test sheet with 3 questions and interviews with 5 students. data validity techniques through triangulation of sources and techniques. The data analysis technique uses stages of data condensation, data display, and conclusion drawing. The research results indicate that students' understanding of basic mathematical concepts in complex numbers varies. Some students show deep understanding, while others still need better understanding. This research provides a significant contribution in describing the understanding of Tadris mathematics students at UIN K.H. Abdurrahman Wahid Pekalongan relates abstract mathematical concepts in depth, which is an important basis in understanding complex analysis. This research provides a significant contribution in describing the understanding of Tadris mathematics students at UIN K.H. Abdurrahman Wahid Pekalongan relates the concept of abstract mathematics in depth.
