Abstract

This article aims to describe students' mathematical representation abilities by utilizing mathematics learning media. Research using the literature review method is based on previous studies that are relevant regarding mathematical representation abilities, as well as a mathematics teaching media. From articles obtained by searches through Google Scholar and also the Science Direct and ERIC databases. The number of articles studied was 21 from national and international journals indexed by Sinta and Scopus. The results of the study show that using mathematics learning media can improve and train students in solving mathematical problems. One of the abilities students must have is the ability to represent mathematically, so that it is easier to present a solution to a problem. Keywords: Mathematical Representation Ability, Mathematics Learning Media.

Abstract

Mathematical Representation Ability (MRE) is one of the important competencies that need to be mastered by students in learning mathematics. One aspect that can affect students' MRE is the character or thinking patterns possessed by the students. This study aims to evaluate the level of validity and reliability of the test instrument designed to measure the mathematical representation ability of junior high school students in solving algebra problems. The method used is a quantitative descriptive method. Based on the results of the validity test using the Aiken's V formula, the four questions were said to be valid, which indicates that the instrument has very good validity and is suitable for use. Meanwhile, the results of the reliability test showed a correlation coefficient value of 0.795, which indicates a fairly good level of consistency in the reliability category so that it is considered reliable. Thus, this instrument is considered suitable for use by teachers in measuring students' mathematical representation abilities in algebra material.
