Analysis of Student's Mathematical Representation Abilities on Plane Figures Subject in the New Normal Era

Abstract

This study aims to analyze the mathematical representation ability of junior high school students on plane figures subject in the new normal era. To prevent the spread of Covid-19 in schools, learning was carried out alternately with 50% face-to-face learning and 50% independently at home. This research is a qualitative descriptive study. The subjects of this study were 20 students studying in seventh-grade students, in the second semester, at Dharmasraya West Sumatra for the academic year 2020/2021. The instruments used in this study were tests of students’ mathematical representation abilities and interviews. The indicators measured are visual representation, expression representation, and word representation. Based on the research conducted, it was found that the level of students’ mathematical representation ability was still low (52.65). In general, students still experience problems in using their mathematical representation skills; therefore, students must be able to hone their representation skills in visual, symbol, and verbal representations. Mastering mathematical representation skills can make it easier for students to solve mathematical problems, and there will be fewer conceptual errors. Moreover, it is necessary to conduct additional research to enhance students’ mathematical representation skills. Keywords: mathematical representation abilities, new normal era, plane figures subject
