PENGGUNAAN KOMIK UNTUK MENDUKUNG KEMAMPUAN REPRESENTASI MATEMATIS SISWA SMP PADA MATERI TEOREMA PYTHAGORAS
Low representation skills are an issue in mathematics learning, with many students still lacking mathematical representation skills, especially in the Pythagorean Theorem. Innovative learning media is needed to improve students' understanding of mathematics learning. This study aims to describe the Mathematical Representation Ability of junior high school students in the Pythagorean Theorem material using comics through the application of the Problem Based Learning (PBL) learning model. The method used is descriptive with 35 students in class VIII.B Junior High School 1 Indralaya. The research instrument was in the form of three descriptive questions with indicators of Mathematical Representation Ability, namely Visual Representation, Symbol Representation, and Verbal Representation as well as interviews. The results of the study showed that the average Mathematical Representation ability of students was 63% and was included in the good category. In detail, the visual representation indicator obtained an average of 72%, the symbol representation indicator of 72%, and the verbal indicator of 46%. These findings show that students' abilities are still dominant in visual and symbolic aspects, while verbal skills are still poor. The causative factors include low motivation in writing words or conclusions in solving a problem, lack of habituation in learning verbal representations, there are still students who think that writing words or conclusions in solving a problem is not important and students' dependence on their peers in the learning process. Thus, the application of the PBL model assisted by Pythagoras Comics can help build students' mathematical representation skills, but it needs to be optimized by habituating questions that meet the indicators of mathematical representation ability, especially in verbal representations.
