The factors that influence students’ solution related to inverse proportion problems

Abstract

Abstract This study aims to explain how factors that influence students that their answer was correct mathematically and plausible on the problem of the inverse proportion concept. The subjects of this study were four students of grade 7th, a junior high school in Bandung. This research used the qualitative method with the triangulation for collecting data in the forms of written test, interview, and documentation. The result of this study analyzed by using relevant theories. This implies the need for analysis of written tests and students interview as evaluation to improve learning. During the study, we found factors that influence students in to find their answers correct mathematically and plausible. These factors include students’ understanding related to inverse proportion concept, understanding of students related to calculating operations, understanding of students related to reading and forming tables, understanding of students in terms of graphs, and understanding of mathematics equation. Based on the results of this study concluded that students could understand the questions with plausible. However, these factors affect students in problem-solving of the inverse proportion concept so that students’ difficulties in finding the right answers mathematically.
