Abstract

Tujuan dari penelitian ini adalah mengembangkan bahan ajar desain didaktis untuk meningkatkan kemampuan berpikir reflektif matematis siswa SMA. Metode Penelitian ini adalah metode kualitatif. Alat pengumpul data dalam penelitian ini berupa tes kemampuan berpikir reflektif awal dan akhir yang merupakan soal uraian sebanyak 5 soal yaitu Tes Kemampuan Berpikir Reflektif  Matematis  (TKBRM). Subjek penelitian ini adalah siswa kelas XI sebanyak 20 siswa di MA Cahaya Harapan Bandung Barat. Kesimpulan dari hasil penelitian ini  adalah 1). Desain didaktis yang berupa bahan ajar (LKS) mendukung siswa untuk meningkatkan kemampuan berpikir reflektif matematis, 2). Instrumen dan LKS yang dihasilkan memenuhi standar dan valid untuk digunakan, 3).Terdapat indikator yang paling rendah dalam pencapaian TKBRM siswa, yaitu indikator mengevaluasi proses penyelesaian, 4). Desain didaktis yang dikembangkan dapat mengatasi rendahnya kemampuan berpikir reflektif matematis siswa pada materi program linear.

Abstract

This study aims to describe the mistakes made by students and analyze the factors that cause students to make mistakes in solving problems on the SPLDV material. This research was conducted at SMP Pasundan 2 Cimahi grade 8 in the even semester. The subjects of this study were students of grade 8E at SMP Pasundan 2 Cimahi. The data collection technique used in this research is by using the method of written tests and interviews. The methods used in data analysis include data reduction, data presentation and conclusion drawing. The results of data analysis can be concluded that in the process of solving the SPLDV material questions students made several mistakes, namely: 1) conceptual errors; 2) calculation errors, and 3) procedural errors. The factors that make students make these mistakes are the low understanding ability of students in mastering concepts, lack of doing exercises to solve various questions, students tend to be in a hurry when working on questions, lack of accuracy of students in solving problems and the high sense of laziness of students in checking back. the result of the answer.

Abstract

The research was aimed at analyzing student's difficulties in resolving social arithmetic on 7th grade class. The method was qualitative descriptive. In one of West Bandung MTSN with 20 students on 7th grade class 2020-2021 school year as subject. The sampling was giving a written test of six questions. After that, the answer will be analyzed. That data were analyzed by Data Reduction, Data Presentation, and Drawn a Conclusion. Result of the research showed that the student's difficulties are 1) understanding the question 2) determining the correct formula 3) the student less precise in answer the questions and 4) lack of understanding concepts. Result of this research hopes that teachers can lead and help the student's difficulties, so that students can improve their math skills especially social arithmetic.
