Analysis of multi-representation ability to solve algebra problem

Abstract

The phenomenon that occurs in everyday life, one of the mathematical topic that was difficult to understand by students is algebraic. In algebra, there are many symbols that make students difficult to understand and understand the concept of algebraic material. This research aims to describe the ability of multi-representation in solving algebraic problems based on students ' mathematical skills (high, moderate and low). Furthermore, the type of research used was descriptive research. The subject of research in this study is class VIII students SMP Negeri 13 Singkawang, odd semester of the school year 2017/2018 Overall the research results show the multi-representation that the student presented to the verbal representation of the average percentage of 54.46%, The average visual representation of the percentage was 59.09% while for symbol representation was obtained an average percentage of 48.92%. In this case, a highly capable subject presents a solution through various representations (verbal, visual and symbol) For medium-capable subjects, it was able to give an answer with symbolic and verbal representation and lacking in visual representation presentation. As for low-capability subjects are less able to present solutions in visual, verbal and symbolic representations.
