Abstract

Tujuan dari penelitian ini adalah untuk mendeskripsikan representasi matematis siswa bergaya kognitif reflektif dalam menyelesaikan masalah sistem persamaan linear dan untuk mendeskripsikan representasi matematis siswa bergaya kognitif implusif dalam menyelesaikan masalah sistem persamaan linear. Peneliti menetapkan empat subjek penelitian dari hasil tes gaya kognitif reflektif-implusif yang terdiri dari dua subjek bergaya kognitif reflektif dan dua subjek bergaya kognitif implusif. Peneliti melakukan tes masalah sistem persamaan linear dan wawancara terhadap ke empat subjek tersebut. Jenis penelitian yang digunakan adalah studi kasus dengan pendekatan kualitatif. Teknik analisis data yang digunakan adalah reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa bergaya kognitif reflektif mampu menyelesaikan masalah sistem persamaan linear menggunakan representasi visual dan simbolik, serta siswa bergaya kognitif reflektif mampu menggunakan representasi verbal namun masih kurang tepat. sedangkan sisiwa bergaya kongnitif implusif mampu menyelesaikan masalah sistem persamaan linear menggunakan representasi verbal. The purpose of this study is to describe the mathematical representation of students with reflective cognitive style in solving linear equation system problems and to describe the mathematical representation of students with impulsive cognitive style in solving linear equation system problems. Researchers set four research subjects from the results of the reflective-impulsive cognitive style test consisting of two subjects with reflective cognitive style and two with impulsive cognitive style. The researcher conducted tests on the system of linear equations and interviewed the four subjects. The type of research used is a case study with a qualitative approach. Data analysis techniques are data reduction, presentation, and conclusions. The results showed that students with reflective cognitive styles could solve linear equation system problems using visual and symbolic representations, and students with reflective cognitive styles could use verbal representations but were still not precise. while students with impulsive cognitive style are able to solve linear equation system problems using verbal representations.

Abstract

The numeracy literacy of Indonesian students at the international level is still relatively low. This can be seen based on the results of the PISA test. In 2015, Indonesia obtained a PISA score of 386 for mathematics from each country's average score, namely 487. Low numeracy literacy can occur due to student errors in solving numeracy questions, namely conceptual and work procedure errors. Numerical Literacy is closely related to solving mathematical problems, primarily found in questions of the Higher Order Thinking Skills (HOTS) type. Therefore, no research examines numeracy skills in solving HOTS problems. This research uses a qualitative approach with a case study type. This study's subjects were class VIII MTs Negeri 5 Tulungagung students. This study used 2 data collection techniques: tests in the form of descriptions and interviews. The analysis model used is Miles and Huberman's model, which consists of data reduction, data display, and conclusion drawing/verification. The results of this study indicate that the level of numeracy ability of students at MTs Negeri 5 Tulungaguang is quite diverse, although, in percentage terms, those with moderate numeracy skills are more dominant. (1) Students with low numeracy abilities cannot fulfil all indicators of Numerical Literacy ability in solving problems, (2) Students with moderate numeracy ability can only fulfil three indicators of Numerical Literacy ability in solving problems, and (3) Students with high numeracy abilities can fulfil all indicators of Numerical Literacy ability in solving problems.
