Student's Multiple Representation in Solving Addition and Subtraction of Fraction Problem

Abstract

Fraction is one of mathematics' topics that difficult to be understood. Many representation form from fraction. Representation has an important role in mathematic. Representation helps student to create mathematic ideas more concrete. So, multi-representation is needed in fractional problem solving. This study is to describe students' ability of multi-representation in solving fraction problem. The sample of this study is the VII-B grade students of a state junior high school in Munjungan city, East Java. There are eight classes from A to H, VII-B was chosen purposively. There were 10 boys and 12 girls in VII-B. Multi-representation test was given to each student. Three volunteer were chosen as our respondents. The semi-structured interview was utilized to investigate the process and students conceptual of fraction. This study shows that the students still have difficulties to represent fraction. The students were success to solve model representation, but they have difficulty to solve fraction in number line. The error in representation on addition and subtraction of fraction problem shows that student did not understand fraction concept well. Student ability on multi-representations should be conducted through exercise continually.
