Abstract

This study was conducted to determine the mathematical connection abilities of ninth-grade junior high school students in learning mathematics on the subject of Two-Variable Linear Equation Systems (SPLDV). This study used a qualitative method with a descriptive approach, which aims to understand phenomena in depth through direct observation. The study was conducted at a junior high school in Riau, with a sample of 12 ninth-grade students who had studied the topic of Systems of Linear Equations with Two Variables (SPLDV). The sampling technique used in this study was purposive sampling, selecting three students for further analysis based on the following criteria: (1) students with high mathematical connection skills (all indicators met), (2) students with moderate mathematical connection skills, and (3) students with low mathematical connection skills. The instruments used in this study consisted of a written test and an interview guide. The written test comprised three essay questions designed to measure students' mathematical connection skills in the SPLDV material. The results and discussion of this study showed that 6 students had high mathematical connection skills, 2 students had moderate mathematical connection skills, and 4 students had low mathematical connection skills
