Students’ Procedural Design in Solving System of Linear Equation in Two Variable Problems (SLETV) at Junior High School
This study aims to analyze students' procedural errors in solving SLETV problems. Procedural fluency is one of the supporting factors for students to be proficient in learning mathematics. It is crucial to identify students’ procedural fluency in SLETV topic. The subjects of this study are junior high school students in Pandeglang. Subjects were randomly selected based on high, medium, and low mathematical abilities. The method of this research is descriptive method. The assessment criteria for procedural fluency used three items, namely eficiency, accuracy, and flexibility. These criteria refer to the ability of students to apply knowledge about procedures as well solve an SLETV problem accurately. In this research the students’ procedural fluency level is categorized into three, such as fluent, quiet fluent, and less fluent. The finding of this reserash shows that not all students are fluent in mathematical procedure and not all students have the ability to solve a mathematical problem efficiently, flexibly, and accurately. Furthermore, procedural fluency must be supported by strong conceptual understanding to promote students' mathematical procedural fluency. Finally, this study gives good contribution to observe the procedural fluency of mathematics in junior high school.
