Abstract

Mathematical representation ability is the ability to present notations, symbols, tables, pictures, graphs, diagrams, equations, or other mathematical expressions into other forms possessed by students to find solutions to a problem at hand. Therefore, teachers should provide sufficient opportunities for students to be able to train and develop mathematical representation skills as an important part of solving the problems given. The mathematical representation ability of students is still low. Students still find it difficult to solve mathematical problems related to aspects of verbal indicators, picture indicators, and symbol indicators. This can be found in linear programming material. Also, linear programming material is often considered difficult material by students in learning mathematics. This study aims to describe students' mathematical representation abilities including symbol representation, image representation, verbal representation on linear programming material in class XI SMA Negeri 3 Ambon. The type of research used is combination research (mixed methods). The research was conducted at SMA Negeri 3 Ambon with 36 research subjects from class XI MIPA 4 and the subjects chosen to be interviewed were based on the results of the mathematical representation ability test. From the results of the mathematical representation ability test on linear programming material, students are grouped based on the very high, high, medium, low, and very low categories. The subjects interviewed were 1 student with a very high category; 1 student with a low category, and 1 student with a very low category. Linear programming material is given to help students improve mathematical representation abilities. The largest percentage of students' test results are in the very low category. Based on the test results, it shows that the mathematical representation ability of students on symbol representation is higher than image representation and verbal representation. Meanwhile, from the three subjects interviewed, it was found that subjects tended to fulfill the indicator of symbol representation ability compared to the indicators of image representation and verbal representation

Abstract

This research is descriptive because it aims to describe students' mathematical representation ability. Mathematical representation is related to ways of expressing mathematical ideas. Mathematical representation is divided into verbal, visual/pictorial, and symbolic representations. The subjects of this study were 40 new Mathematics Education study program students. Data were collected using test and interview techniques. Furthermore, the data were analyzed using descriptive and qualitative statistics. The results showed that only 10% of the students had the mathematical representation ability in the good category, 12.5% in the moderate category, 10% in the poor category, and 67,5% in the very poor category. In detail, for verbal skills, there is 2.5% in the very good category, 7.5% in the good category, 17.5% in the moderate category, 15% in the poor category, and 55% in the very poor category. For the ability of visual/pictorial representation, there is 2.5% in the very good category, 7.5% in the good category, 12.5% in the moderate category, 7.5% in the poor category, and 70% in the very poor category. Furthermore, for the symbolic representation ability, 10% is in a good category, 10% in the moderate category, 7.5% in the poor category, and 72.5% in the very poor category. Based on the classroom observation and interview, the low mathematical representation ability is caused by two main things, namely (1) relatively low prerequisite knowledge and (2) mathematics learning, which is dominated mainly by teachers; learning does not provide opportunities for students to develop mathematical representation skills
