PEMBELAJARAN MATEMATIKA DENGAN MODEL PROBLEM SOLVING PADA MATERI SISTEM PERSAMAAN LINEAR DUA VARIABEL BERBANTUAN MEDIA KARET-STAR (KARAMBOL ETNO SPLDV NUSANTARA) UNTUK MENINGKATKAN KEMAMPUAN LITERASI NUMERASI PADA SISWA

Abstract

Numerical literacy is one of the most important abilities in today's era. For students, these abilities should be possessed considering that these competencies have been tested in the AKM (Minimum Competency Assessment). However, many students do not master numeracy literacy competence, because their mindset towards mathematics is not good. This resulted in the inhibition of mathematical problem solving abilities in students, especially in material of a two-variable linear equation system. Based on the literacy data that has been collected, information is obtained that the need for habituation of problem-based learning, one of which is a problem solving model. The goal is that students are trained and familiar with mathematical problems related to everyday life so that they will improve their mathematical problem solving abilities. Learning the material can be done with a problem solving learning model considering that there are many problems around students that can be solved with this concept. This learning also involves the KARET-STAR game media. KARET-STAR is a mathematical game media in the form of a modified carom board and there is a question card containing story questions related to the culture of the archipelago and clarified pictures in beside the questions. The learning is carried out through stages (1) teacher gives a problem of a two-variable linear equation system related to the culture of the archipelago, and provides the right solution concept, and (2) students play the media which is guided by the teacher. The existence of such learning needs to be done for the habituation and improvement of students' numeracy literacy skills.
