Abstract

This article discusses the use of GeoGebra as a tool in learning Systems of Linear Equations in Two Variables (SPLDV). GeoGebra, created by Markus Hohenwarter in 2001, has grown to become one of the most popular educational tools worldwide, allowing students and teachers to explore mathematical concepts visually and interactively. With features such as graph generation, mathematical object manipulation, and intersection analysis, GeoGebra facilitates a deeper understanding of SPLDV. The purpose of this article is to explain how using GeoGebra can simplify the learning process for Systems of Linear Equations in Two Variables (SPLDV). The research methodology used includes qualitative and quantitative approaches, by measuring student understanding before and after using GeoGebra. The research results show that GeoGebra not only improves understanding of mathematical concepts, but also develops students' problem solving and critical thinking skills. Thus, GeoGebra contributes significantly to improving the quality of mathematics teaching and learning.

Abstract

Kondisi pasca pandemi ini membuat siswa mempelajari setiap materi dari gadgetnya. Hal tersebut membuat pola pikir siswa sangat terbatas karena kepraktisan yang didapatkannya. Hanya dengan membuka satu situs internet, semua jawaban tentang materi yang dipelajarinya ada disitu. Hal tersebut membuat kemampuan penalaran matematis siswa tidak cukup berkembang. Oleh karena itu diperlukan adanya upaya dalam meningkatkan kemampuan penalaran matematis siswa yang salah satunya dengan memberikan pembelajaran yang sesuai dengan gaya belajar siswa. Dalam pembelajaran berdiferensiasi itu sendiri terdapat beberapa aspek kebutuhan siswa yang harus dipenuhi, yakni kesiapan, minat dan gaya belajar siswa. Pembelajaran berdiferensiasi mengedepankan konsep bahwa setiap siswa memiliki minat, potensi dan bakat tersendiri. Metode penelitian ini menggunakan metode kualitatif-deskriptif dengan tujuan mendeskripsikan kemampuan penalaran siswa dengan menggunakan pendekatan pembelajaran berdiferensiasi. Hasil dari tes tersebut menunjukan bahwa ketiga orang subjek ini memperoleh nilai yang cukup memuaskan setelah dilakukan pengelompokan berdasarkan gaya belajar. Nilai subjek yang pertama dengan gaya belajar visual meningkat dari 56 menjadi 82 , nilai subjek 2 dengan gaya belajar auditori meningkat dari 68 menjadi 80 dan nilai subjek 3 dengan gaya belajar kinestetik meningkat dari 65 menjadi 75. Dengan begitu kemampuan penalaran matematis siswa berkembang cukup baik dengan dilakukannya pendekatan pembelajaran berdiferensiasi.

Abstract

The critical problem in this research is the lack of instructional strategies that simultaneously enhance literacy and numeracy skills while addressing students' diverse learning needs. While the Problem Based Learning model fosters problem-solving, its implementation often overlooks individual differences, making its integration with differentiated instruction crucial and challenging. One of the mathematical skills that students must have is literacy numeracy skills. However, based on initial observations at one of the public senior high schools in Kuningan, students' literacy and numeracy abilities are still low. This study aims to examine the effectiveness of the Integrated Problem Based Learning Differentiated Instruction model in improving high school students’ literacy and numeracy skills. The research employed an experimental method with a one-group pre-test and post-test design involving 36 class XI students. Data were collected through literacy numeracy tests administered before and after the intervention. Data analysis was conducted using N-gain to measure the improvement in students' literacy numeracy ability. The research results were obtained from test results N-Gain, with scores of 0.56 (medium category) and an increase percentage of 56.05%. Students show better abilities in understanding, interpreting, and analyzing problem-based questions related to mathematical concepts

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan siswa dalam memahami konsep dari literatur pada SPLDV. Tujuan penelitian ini untuk melakukan eksplorasi mengenai learning obstacle yang dialami oleh siswa SMP ketika mereka mencoba memahami konsep SPLDV. Oleh karena itu, diharapkan kedepannya penguasaan konsep dasar SPLDV dapat tercapai secara optimal. Penelitian ini merupakan penelitian kualitatif dengan desain Didactical Design Research (DDR). Subjek dalam penelitian ini berjumlah 3 siswa yang dipilih berdasarkan purposive sampling. Instrumen penelitian yang digunakan yaitu tes pemahaman konsep dan pedoman wawancara. Analisis data dalam penelitian ini meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa masih menghadapi sejumlah kesulitan dalam memahami materi spldv. Kendala-kendala yang dihadapi siswa antara lain yaitu (1) kesulitan dalam merumuskan ulang konsep sistem persamaan linear dua variabel dan kurangnya kemampuan untuk memberikan contoh SPLDV. (2)Kesulitan dalam menentukan titik potong saat membuat grafik SPLDV. (3) Kekeliruan dalam melakukan operasi hitung dan mengembangkan model matematika. (4) Kesulitan dalam merancang langkah-langkah yang diperlukan untuk menyelesaikan soal SPLDV. (5) Kesulitan dalam menyelesaikan soal yang berbeda dengan contoh soal yang diajarkan oleh guru. Hal ini menunjukkan adanya beberapa hambatan yang perlu diatasi dalam pembelajaran konsep SPLDV di tingkat SMP.   This research was motivated by the low ability of students to understand concepts from the literature on SPLDV. This research aims to explore the learning obstacles experienced by junior high school students when they try to understand the concept of SPLDV. Therefore, it is hoped that in the future mastery of the basic concepts of SPLDV can be achieved optimally. This research is qualitative research with a Didactical Design Research (DDR) design. The subjects in this research were 3 students selected based on purposive sampling. The research instruments used were concept understanding tests and interview guidelines. Data analysis in this research includes data reduction, data presentation, and concluding. The research results show that students still face several difficulties in understanding SPLDV material. The obstacles faced by students include (1) difficulties in reformulating the concept of a system of linear equations in two variables and a lack of ability to provide examples of SPLDV. (2) Difficulty in determining the intersection point when creating SPLDV graphs. (3) Errors in carrying out calculation operations and developing mathematical models. (4) Difficulty in designing the steps needed to solve SPLDV problems. (5) Difficulty in solving questions that are different from the example questions taught by the teacher. This shows that several obstacles that need to be overcome in learning SPLDV concepts at the junior high school level.

Abstract

This study aimed to implement a didactic situation design to overcome learning obstacles in the circumference and area of the circle. The method used is qualitative research with Didactical Design Research which goes through the last two stages, namely metapedadidactic analysis and retrospective analysis. The instrument used is a didactic situation design prepared by Rosita, Maharani, Tonah Munfi (2020) and interview guidelines. Based on the implementation results, the didactic situation that has been designed has not been able to overcome students' learning obstacles fully. In addition, a new learning obstacle appears in the concept of the circumference of a circle. Not all students can measure the length of the curvature of a circle because there are inaccurate measurement results. In this study, the didactic design was revised regarding the circumference and area of a circle based on metapedadidactic and retrospective analysis.Penelitian ini bertujuan untuk mengimplementasikan rancangan situasi didaktis sebagai upaya mengatasi learning obstacle pada materi keliling dan luas lingkaran. Metode yang digunakan adalah penelitian kualitatif dengan Didactical Design Research yang melalui dua tahap terakhir yaitu analisis metapedadidaktik dan analisis retrospektif. Instrumen yang digunakan berupa rancangan situasi didaktis yang telah disusun oleh Rosita, Maharani, Tonah Munfi (2020) serta pedoman wawancara. Berdasarkan hasil implementasi, situasi didaktis yang telah dirancang belum sepenuhnya dapat mengatasi learning obstacle siswa. Selain itu, terdapat learning obstacle baru yang muncul pada konsep keliling lingkaran yaitu tidak semua siswa mampu mengukur panjang lengkungan lingkaran karena terdapat hasil pengukuran yang kurang akurat.Pada penelitian ini, dilakukan perbaikan kembali desain didaktis mengenai konsep keliling dan luas lingkaran yang disusun berdasarkan analisis metapedadidaktik dan retrospektif.
