Abstract

This study aims to analyze students' mathematical literacy in solving geometry problems reviewed from learning styles. This type of research is descriptive research. The approach used in this study is a qualitative approach. Data collection techniques include learning style questionnaires, written tests, and interviews. The credibility of the data in this study uses time triangulation. The data was analyzed descriptively to describe the results of students' mathematical literacy tests. The results of the study show that 1) students with visual learning styles in mathematics literacy are at level 2, because they are only able to solve level 1 and level 2 mathematics literacy problems, visual students have difficulty in solving mathematics literacy problems at a higher level; 2) Students with an auditory learning style in mathematical literacy are at level 4, able to do a more in-depth analysis when solving math literacy problems from level 1 to level 4, but have difficulty solving problems in levels 5 and 6; 3) Students with kinesthetic learning styles in mathematics literacy are only at level 1; kinesthetic students have great difficulty in solving mathematics literacy problems at a higher level.

Abstract

Pendidikan yang efektif memerlukan pendekatan yang relevan dengan keberagaman budaya peserta didik, terutama untuk meningkatkan pemahaman konsep abstrak seperti penyajian data. Namun, dalam praktiknya, pembelajaran matematika sering kali bersifat monoton dan kurang mengaitkan materi dengan latar belakang budaya peserta didik, sehingga menyebabkan rendahnya hasil belajar. Penelitian ini bertujuan untuk mendeskripsikan penerapan Culturally Responsive Teaching (CRT) melalui model Problem-Based Learning (PBL) dalam meningkatkan hasil belajar peserta didik pada materi penyajian data. Penelitian ini menggunakan jenis penelitian tindakan kelas (PTK) dan dilaksanakan dalam dua siklus. Setiap siklus terdiri dari empat tahap yaitu merencanakan, melaksanakan, mengamati, dan merefleksikan. Subjek penelitian adalah peserta didik kelas VII yang berjumlah 30 orang, sedangkan instrumen yang digunakan meliputi lembar observasi dan tes hasil belajar. Hasil penelitian menunjukkan bahwa penerapan pendekatan CRT melalui model PBL secara signifikan meningkatkan hasil belajar peserta didik. Pada siklus I, terdapat 14 peserta didik (53,3%) yang mencapai ketuntasan belajar, sedangkan pada siklus II jumlah tersebut meningkat menjadi 24 peserta didik (86,7%).

This study aims to describe the thought process of students in solving problems in terms of personality types guardian and idealist in class XI SMA Negeri 5 Palu. This research is a qualitative descriptive research. The main instrument in this research is the researcher himself and the supporting instruments are The Keirsey Temperament Sorter (KTS), math problems, and interviews. The results of this study show that guardian students and idealist students are able to perform all stages of the thinking process in solving math problems, namely receiving information, processing information, and forming conclusions. Guardian and idealist students at the stage of receiving information read the problem well. Guardian students read enough once to understand the problem, while idealist students read repeatedly to understand the problem. At the information processing stage, guardian students can explain the problem solving plan while idealist students have difficulty explaining the solution plan. At the conclusion formation stage, guardian students consistently solve the problem according to what was previously planned. idealist students at the conclusion formation stage can solve the problem even though at the information processing stage they cannot explain the solution plan.
