Abstract

One of the factors that influence the ability to solve mathematical problems is that students do not like mathematics and lack the ability to understand concepts. The purpose of this study was to analyze the effect of math anxiety on students' mathematical problem solving abilities. This research uses SLR (Systematic Literature Review). The result of this study is that the effect of math anxiety on problem solving abilities is negative. Based on the studies reviewed, it can be concluded that the level of students' math anxiety is high, so the resulting problem-solving ability is low, and vice versa. Problem solving abilities are strongly influenced by students' math anxiety.

Abstract

Problem-based learning is a learning model that uses real-life problems that require authentic investigations to construct knowledge actively and collaboratively. The aim of this study was to capture the research landscape related to problem-based learning applied to students at the middle school level from 1998 to 2023. A descriptive bibliometric analysis method was used in this study. The data obtained was taken from the Scopus database. The results of the study show that publications related to problem-based learning, especially in middle schools, go up and down every year. Publications in 2003 have been cited more than any other year. The United States of America is the most influential country in this field. publications in journals related to problem-based learning research applied to middle school students are mostly at the Q1 rank, namely 45 journals. The research focus is divided into 3 namely, 1) knowledge, skills and development; 2) effect, self-efficacy, achievement and effectiveness; 3) middle school students, environment and abilities. These three research focuses can be used as a reference for future researchers to determine the focus of their research related to problem-based learning

Abstract

Penyelesaian masalah dan daya juang produktif memiliki hubungan yang erat dalam pembelajaran matematika. Siswa yang memiliki daya juang produktif cenderung memberikan pengaruh positif pada bagaimana siswa mengatasi kesulitannya saat menyelesaikan masalah. Tujuan dari penelitian ini adalah untuk menganalisis kemampuan siswa dalam menyelesaikan masalah kontekstual berdasarkan struktur kalimat ditinjau dari daya juang produktif serta mendeskripsikan strategi pembelajaran yang sesuai untuk mendorong daya juang produktif siswa. Penelitian ini merupakan penelitian kualitatif. Penelitian ini dilakukan di salah satu SMP Swasta Kota Bandung yang berjumlah 20 siswa. Metode yang digunakan adalah tes, wawancara dan think aloud. Tes divalidasi oleh ahli pendidikan matematika pada validitas konten, konstruk dan muka. Analisis data pada penelitian ini mencakup reduksi data, penyajian data dan kesimpulan. Kesimpulan dari penelitian ini adalah bahwa siswa dengan daya juang produktif yang tinggi mampu menyelesaikan soal dengan struktur bahasa kompleks dan penyelesaian kompleks. Sedangkan siswa dengan daya juang produktif rendah, masih kesulitan dalam menyelesaikan soal dengan stuktur bahasa kompleks maupun penyelesaian kompleks. Adapun beberapa strategi yang dapat dilakukan untuk mendorong daya juang produktif adalah dengan memberikan soal yang menantang, mengajukan pertanyaan pendorong, memberikan waktu yang cukup serta menekankan pentingnya proses kepada siswa.

Abstract

Membuat model matematika adalah kemampuan menerjemahkan situasi realitas ke dalam bahasa matematika. Model matematika sama dengan kemampuan representasi matematis. Ada tiga representasi matematika yang menjadi sorotan dalam penelitian ini yaitu konkrit, piktorial, dan abstrak. Penelitian ini dilaksanakan di salah satu sekolah di kabupaten Bandung Barat sejumlah 51 siswa. Peneliti memilih siswa berdasarkan tingkatan daya juang produktifnya yaitu tinggi, sedang dan rendah. Siswa yang memiliki daya juang produktif tinggi dapat menjawab ketiga soal dengan benar dengan model matematika abstrak. Siswa yang memiliki daya juang produktif yang sedang dapat menjawab dua soal dengan benar dengan model matematika konkrit dan abstrak. Siswa yang memiliki daya juang produktif yang rendah dapat menjawab satu soal dengan bantuan intervensi/perlakuan dari peneliti guna mendorong daya juang produktif dengan memberikan soal pemecahan masalah dan mengajukan pertanyaan gaya Socrates. Bantuan ini tidak menghilangkan kesempatan siswa untuk aktif berfikir, sebaliknya melalui metode ini siswa dituntut untuk memaknai pengetahuannya. Sebanyak 2% siswa mengerjakan soal dengan menggunakan model matematika konkret dan seluruh siswa yang mengerjakan dengan menggunakan model matematika konkret tersebut dapat menjawab soal dengan benar. Sebanyak 7.5% siswa mengerjakan soal dengan menggunakan model pictorial dan seluruh siswa yang mengerjakan dengan menggunakan model pictorial tersebut dapat menjawab soal dengan benar. Sebanyak 90.5% siswa memilih untuk mengerjakan soal dengan menggunakan model matematika abstrak. Hanya 12.5% siswa yang mampu mengerjakan soal dengan tepat. Sebanyak 78% siswa yang gagal diakibatkan mereka memilih menggunakan model matematika abstrak padahal mereka belum menguasai model matematika abstrak dengan baik.

Abstract

Understanding a concept is not only for mastering the next concept. It is the foundational skill used to solve mathematical problems. This study aims to explore students' conceptual understanding.This research is qualitative research with phenomenology. The participants in this study consisted of 18 eighth-grade students from one of Bandung's private secondary schools. After the students were given the test, six students were selected as research subjects. This aims to ensure that data can be obtained thoroughly and comprehensively. Data collection techniques included tests, interviews, and observations, with research instruments comprising a test and an interview guideline. Data saturation has been achieved. The results of this study are as follows: 1) students with relational understanding are fewer in number than students with instrumental understanding. 2) students find it most difficult to use the interconnections of various mathematical concepts in solving problems. 3) students' difficulties are due to their lack of ability in the concept of basic operations and their lack of understanding of the problems. Therefore, teachers need to strengthen students' understanding of basic operations and the concepts of mean, mode, and median to effectively connect these concepts with their problems.

Abstract

This study aims to analyze and describe the mathematical problem-solving abilities of students in set theory, specifically within a seventh-grade class at a private school in Bandung. The research employed a qualitative case study approach, collecting data through tests and documentation. A diagnostic test served as the primary instrument for evaluating students' problem-solving skills. The findings reveal distinct patterns in how students approach mathematical problems, correlating with their achievement levels. High-achieving students consistently followed Polya's four stages of problem-solving: understanding the problem, devising a plan, carrying out the plan, and looking back to reflect on their solution. In contrast, moderate-achieving students generally adhered to the first two stages, namely understanding the problem and carrying out the plan, often omitting the reflective stage. Low-achieving students predominantly focused on the initial stage of understanding the problem, struggling to advance beyond this point. The study highlights that the ability to understand the problem is the most developed skill among students, as it is the step where most students succeeded. However, devising a plan was identified as the most challenging aspect, with the fewest students able to correctly formulate a strategy for solving the problems. These findings suggest that while understanding is a common strength, there is a need for targeted interventions to improve students' abilities to plan and execute problem-solving strategies effectively
