Abstract

This study aims to know the description of mathematical communication skills in terms of students' mathematics ability in class IX in solving problems on the subject of quadratic equations. The type of research is qualitative research with a descriptive approach. There were 6 research subjects namely two students that have high-ability, two students that has medium-ability, and two students that has low ability. The instruments used in data collection are written tests and interviews. The results showed that subjects with high mathematical abilities were sufficiently able to describe and state problem situations in written or image form properly, were able to use mathematical symbols and terms appropriately and were able to connect algebraic expressions into mathematical ideas. Subjects with moderate mathematical abilities are able to use mathematical symbols and terms appropriately but are less able to describe and state problem situations in written or image form properly and are also less able to connect algebraic expressions to mathematical ideas. Subjects with low mathematical abilities are not able to describe and state problem situations in written or image form properly and correctly, are less able to use mathematical symbols and terms appropriately and have not been able to connect algebraic expressions into mathematical ideas. The results of this study are expected to add insight and improve students' mathematical communication skills, especially in solving math problems related to the application of everyday life.

Abstract

This study aims to determine how the mathematical representation ability of seventh grade students at SMPN 7 Makassar in solving algebraic form problems. This type of research is qualitative research with a descriptive approach. The subjects of this study were 3 students from class VII.8 SMPN 7 Makassar in the 2021/2022 academic year. The focus of this research is the ability of visual representation, symbolic representation (mathematical expression) and verbal representation. The instruments used in data collection are mathematical representation ability test questions and interview guidelines. The results showed that: (1) Representation ability on visual indicators is moderate. The three subjects were able to present images of the given story problems but the subjects still had difficulty in presenting images of the given mathematical symbols. (2) Mathematical representation ability on mathematical expression indicators is low. There are 2 subjects who are able to solve problems involving mathematical expressions but the three subjects have not been able to create equations or mathematical models from other given representations. (3) Mathematical representation ability on verbal indicators is quite high. On average, subjects were able to solve problems by presenting statements using everyday language from the given mathematical equations even though there were still subjects who were mistaken in solving the problem.
