Abstract

This research aims to find out and describe how high the mathematical communication skills of Grade IX Middle School (SMP) students are on the material Systems of Linear Equations in Two Variables (SPLDV). This study involved students in class IX-D at one of the State Middle Schools in Karawang Regency for the 2023/2024 academic year as research subjects. Purposive sampling technique was used to select subjects and obtained 32 students. Qualitative descriptive research was used. The data collection method was carried out using a mathematical communication ability evaluation tool which consisted of three descriptive questions. The data processing technique used descriptive statistics to determine the high, medium and low categories of all students in classes IX-D. It is proven from the result of the students’ mathematical communication skills test that they are in the low classification because they show an average score of 32,00957.

Abstract

Epistemological obstacles arise due to the limited knowledge possessed by students in certain contexts so when facing different contexts, students will experience obstacles in finding a relationship and conceptual linkage. This study aims to describe students' epistemological obstacles in solving problems on the subject of quadratic equations. The approach used in this study is a qualitative approach with a descriptive method. Data collection was obtained by giving a written test of three quadratic equation questions adopted from previous studies and conducting unstructured interviews. The subjects studied were all ninth-grade students of SMP Negeri 2 Majalaya, Karawang, and using probability random sampling techniques, a sample of 44 students was taken. The test data were then processed and grouped into three categories, namely high, medium, and low. Then the students' answers were analyzed and reviewed from the epistemological obstacle indicators. Then the researcher conducted unstructured interviews to find out more about the obstacles that occurred to the three selected participants. The results of the study showed that the epistemological obstacles experienced by students in solving problems on the subject of quadratic equations were: (a) conceptual obstacles, there were participant errors in determining definitions and not writing formulas in a given problem; (b) procedural obstacle, there are participants who have not been able to solve the problem according to the requested procedure; and (c) operational technique obstacle, there are participants who have errors in calculations in the process of working on certain steps and errors in writing formulas, the process of working, and the final results in solving the problem. It is hoped that the findings in this study can have a significant impact on the mathematics learning process, both theoretically and applicatively.

Abstract

Matematika merupakan salah satu mata pelajaran yang memegang peranan penting dalam kehidupan sehari-hari, namun sebagian besar siswa kurang menyukai matematika karena dianggap terlalu rumit dan banyak mengandung misteri, hal ini menimbulkan rasa takut, gugup serta gelisah saat belajar matematika. Ketakutan, gugup serta gelisah saat belajar matematika merupakan pengaruh dari kecemasan matematis. Kecemasan matematis dianggap sebagai penghambat belajar yang dapat mempengaruhi kinerja kognitif siswa. Tujuan dari penelitian ini adalah untuk mengetahui tingkat kecemasan matematis siswa kelas VII SMP. Subjek dalam penelitian ini adalah sebanyak 18 siswa kelas VIIB SMPIT ARMANIYAH Tahun Pelajaran 2023/2024. Metode penelitian yang digunakan adalah metode penelitian deskriptif dengan menggunakan pendekatan kualitatif. Pengambilan data diperoleh dengan menggunakan metode non tes yaitu instrumen berupa angket yang di dalamnya memuat 32 pernyataan, dimana setiap pernyataan memuat 4 aspek dari indikator kecemasan matematis yang diadopsi dari penelitian terdahulu. Data skor kecemasan matematis diolah dan dikelompokkan menjadi tiga kategori, yaitu : rendah, sedang dan tinggi. Hasil penelitian menunjukkan bahwa (1) tingkat kecemasan matematis yang dialami siswa tergolong sedang. (2) sebagian besar siswa menganggap materi matematika sulit untuk dipahami karena materi yang banyak dan rumit. Siswa yang mengalami kesulitan akan merasa tidak nyaman saat belajar matematika dan merasa kurang percaya diri saat pembelajaran matematika.

Abstract

Penalaran merupakan suatu faktor yang mempengaruhi hasil belajar siswa. Kemampuan penalaran matematis siswa yang baik, akan menghasilkan pemahaman dan pemecahan masalah matematis siswa yang lebih mendalam. Penelitian ini bertujuan untuk menganalisis kemampuan penalaran matematis siswa kelas VIII SMP terhadap soal-soal matematika untuk sub materi segitiga. Subjek dalam penelitian ini adalah siswa kelas VIII.7 TA 2022/2023 disalah satu SMP di kabupaten Bogor sebanyak 38 siswa. Penelitian ini menggunakan metode deskriptif kualitatif. Teknik pengumpulan data pada penelitian ini yaitu tes tulis dan wawancara. Instrumen tes tulis diadopsi dari skripsi, penilaian hasil tes tulis berdasar pada point-point indikator kemampuan penalaran matematis. Wawancara dilakukan dengan wawancara tak terstruktur. Berdasarkan hasil analisis data penelitian subjek dibagi menjadi 3 kategori yaitu dengan tingkat kemampuan penalaran tinggi, sedang, dan rendah. Diambil 3 siswa berdasar pada tingkat kemampuan penalaran untuk dianalisis dan diwawancara. Siswa dengan kategori tinggi (26%) mampu menyelesaikan setiap soal berdasar pada indikator kemampuan penalaran. Siswa dengan kategori sedang (47%) belum mampu mencantumkan alasan penarikan kesimpulan pada kalimat kesimpulan. Siswa dengan kategori rendah (26%) belum mampu menyelesaikan setiap soal berdasar pada indikator kemampuan penalaran. Hasil penilaian didapat nilai terendah 0,0 dan nilai tertinggi 91,0. Mengacu pada KKM sekolah yaitu 75, pada hasil data penelitian didapat siswa dengan capaian tuntas sebanyak 5 siswa dan tidak tuntas sebanyak 33 siswa, sehingga kemampuan penalarannya masih rendah.

Abstract

Creative thinking skills are the ability to communicate ideas, solve problems, and create something that has never been discovered by others. Geometry is one of the areas of mathematics taught in schools that requires the use of reasoning, calculation analysis, and creative imagination. This study aims to review the literature on the topic of creative thinking skills in geometry learning in junior high school. SLR (Systematic Literature Review) on “Creative Thinking Ability” and “Geometry” that have been published in the last ten years served as the research methodology. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA), which generates research articles for systematic reviews between 2014 and 2024, became the basis of this study. The results show that there are several levels of creative thinking skills in geometry learning, namely high, medium, and low, using various approaches, models, and media support. Through the use of media and problem development tools, the results showed a high level of creative thinking ability. A moderate level was achieved when students only showed one or two of the three previously mentioned indicators of creative thinking ability, or when they had not fully met the indicators. The low level was achieved when students did not meet any of the creative thinking indicators and were mostly directed by teacher examples or standard working procedures without any input from students on how to solve the problem
