Abstract

This study aims to analyze the difficulties of junior high school students in solving mathematics problems on the Pythagorean Theorem material in terms of numerical ability based on the limitations of specific studies on numerical barriers affecting students' accuracy in applying the Pythagorean concept. The approach used is qualitative with a case study method. The research subjects consisted of 24 ninth-grade students at an Islamic junior high school in East Karawang, selected through purposive sampling based on the subject teacher's recommendations regarding learning barrier characteristics. The instruments used were a numerical ability test, Pythagorean Theorem questions, and interview guidelines. The results showed that the majority of students had low numerical ability and experienced difficulties in various indicators, such as performing calculations, thinking logically, problem solving, and recognizing number patterns. Even students with high numerical ability still had difficulty determining the slant side in Pythagorean problems. These findings indicate the importance of considering numerical ability in the learning process to develop more targeted and personalized learning methods.

Abstract

Mathematical critical thinking is a fundamental competence required for effective algebraic problem solving; however, many students experience difficulties that extend beyond procedural errors. This study aims to analyze junior secondary students’ mathematical critical thinking processes in solving algebraic problems based on the Watson–Glaser critical thinking indicators. Employing a qualitative descriptive design, the study involved 40 seventh-grade students from a public junior high school in Indonesia. Written test data were used to describe the overall distribution of students’ critical thinking levels, while in-depth qualitative analysis was conducted on three purposively selected students representing high, moderate, and low ability levels. Data were analyzed through indicator-based scoring and qualitative content analysis supported by interview data. The findings reveal that students’ mathematical critical thinking ability was predominantly low, with major difficulties in deductive reasoning and the evaluation of arguments. Qualitative results indicate distinct reasoning patterns across ability levels: high-ability students demonstrated coherent reasoning but weak communication of conclusions, moderate-ability students showed fragmented and inconsistent reasoning, and low-ability students relied heavily on intuitive guessing with limited conceptual understanding. These findings highlight the need for process-oriented, differentiated instructional strategies that explicitly foster critical thinking in algebraic learning.

Abstract

This study aims to analyze students’ mathematical connection skills in solving contextual problems involving flat-sided three-dimensional shapes, based on the limited existing literature regarding students’ thought processes when connecting concepts to complex problems. The research approach adopts a qualitative case study method. The research subjects consisted of 34 ninth-grade students in class IX-H at a junior high school in Jakarta, selected to describe variations in mathematical connection skills. The instrument used was a validated mathematical connection skills test. Data were analyzed in depth through the students’ responses. The results of the study indicate significant variations in connection abilities; the majority of students were able to complete general procedures but faced difficulties with contextual problems requiring the integration of multiple concepts. A disruption in the flow of thinking was observed when students were presented with contextual problem narratives involving complex thinking stages. These findings indicate the importance of strengthening abstraction skills and problem-modeling strategies in the learning process to help students connect various mathematical concepts when solving real-world problems. Penelitian ini berupaya untuk menganalisis kemampuan koneksi matematis siswa dalam menyelesaikan permasalahan kontekstual pada materi bangun ruang sisi datar, yang didasarkan pada masih terbatasnya literatur mengenai proses berpikir siswa saat menghubungkan konsep pada masalah kompleks. Pendekatan penelitian m mengadopsi metode kualitatif jenis studi kasus. Subjek penelitian terdiri dari 34 siswa kelas IX-H di salah satu SMP Jakarta yang dipilih untuk mendeskripsikan variasi kemampuan koneksi matematis. Instrumen yang digunakan berupa tes kemampuan koneksi matematis yang telah dinyatakan valid. Data dianalisis secara mendalam melalui hasil jawaban siswa. Hasil penelitian menunjukkan adanya variasi kemampuan koneksi yang signifikan, mayoritas siswa mampu menyelesaikan prosedur umum namun terkendala pada masalah kontekstual yang membutuhkan integrasi beberapa konsep. Ditemukan adanya keterputusan alur berpikir saat siswa dihadapkan pada narasi soal kontekstual dengan tahapan berpikir kompleks. Temuan ini mengindikasikan pentingnya penguatan kemampuan abstraksi dan strategi pemodelan masalah dalam proses pembelajaran untuk membantu siswa menghubungkan berbagai konsep matematika saat menyelesaikan persoalan dunia nyata.

Abstract

This research was conducted due to the low mathematical problem-solving ability on the mathematics learning outcomes of Vocational High School (SMK) students which are not optimal. The purpose of this study is to analyze the influence of mathematical problem-solving ability on student learning outcomes. The approach in this study uses quantitative with a population of all grade XI students of SMKS Bina Karya 2 Karawang, totaling 103 students, and 26 students as a sample determined through a purposive sampling technique. Essay tests to measure mathematical problem-solving ability and Mid-Semester Test (UTS) scores are the instruments used as indicators of learning outcomes. Data were analyzed through normality tests, linearity tests, and simple linear regression analysis. The study shows that mathematical problem-solving ability has a positive and significant influence on student learning outcomes, with a significance value of 0.000 (<0.05) and a regression equation of Y = 5.342 + 0.596X. The amount of contribution given reaches 45%, which indicates that this ability is one of the important factors in improving learning outcomes, although there are still other factors that play a role.
