Abstract

Mathematical representation ability is one of the abilities that students must have in building concepts and thinking mathematically. Therefore, an effort is needed that is able to accommodate mathematical representation abilities in order to develop optimally, namely a method that provides sufficient opportunities for students to be able to train and develop their mathematical representation abilities. A learning model that presents tasks in the form of problems because with a problem, students will try to find solutions with various ideas and representations so that students^ thinking abilities are truly optimized through the problem solving process. One suitable learning model is the Geogebra-assisted Problem Based Learning learning model. Through the Geogebra-assisted Problem Based Learning learning model, students are expected to be able to present information data back from a representation to diagrams, graphs, or tables- use visual representations to solve problems effectively- draw geometric patterns to clarify problems and facilitate resolution.
The method used in this research is an experimental method with the research subject of level III students of the Mathematics Education Study Program, Suryakancana University in the Linear Program course. The data collection technique was carried out using a test instrument in the form of a student^s mathematical representation ability test and a non-test in the form of a student attitude scale questionnaire towards Geogebra assisted Problem Based Learning.
Based on the results of the research, it is known that: 1) The improvement of students^ mathematical representation skills using geogebra-assisted problem based learning is better than students using ordinary learning- 2) Students have a positive attitude towards learning with Geogebra-assisted Problem Based Learning and mathematical representation questions
