Mathematical beliefs and metacognitive knowledge play significant roles in solving mathematical problems; thus, this study aims to investigate the influence of middle school students' beliefs on their metacognitive knowledge when solving geometry problems. This study utilizes both quantitative and qualitative research methods. A linear regression test was used to determine the effect of middle school students' beliefs on their metacognitive knowledge. The results of the quantitative research analysis were followed up with a qualitative research approach to describe the metacognitive knowledge of students who have high and low confidence in solving geometric problems. This research involved 352 middle school students in the Tarakan area. Based on the results of linear regression, it is known that the beliefs of middle school students have a positive effect on their metacognitive knowledge when solving geometric problems. In addition, it was found that students with different beliefs could solve a given geometry problem, but the approach to solving it varied among subjects. Middle school students have diverse beliefs, but these variations do not affect their capacity to apply their metacognitive knowledge at every stage of solving mathematical problems.

This study aims to analyze the influence of Adversity Quotient (AQ) and learning independence on students' mathematical problem-solving abilities and to explore problem-solving strategies based on differences in AQ and learning independence levels. The study employed a mixed-methods approach with a sequential explanatory design, involving 150 secondary school students. Results showed that AQ and learning independence significantly influenced problem-solving abilities, with learning independence having a greater impact. Students with high learning independence were more innovative and persistent, while those with low independence faced challenges. This study highlights the importance of developing AQ and learning independence to enhance students' problem-solving skills. Education should strengthen these aspects through strategies like project-based learning and resilience training, to better prepare students for real-world challenges.

Students’ mathematical reasoning ability (MRA) is an essential component of mathematics learning, particularly for solving non-routine problems. However, many junior high school students still rely on procedural strategies without sufficient conceptual understanding, resulting in weak reasoning skills, especially in geometry topics such as the Pythagorean Theorem, indicating the need for a detailed analysis of students’ mathematical reasoning ability. This study aims to analyze junior high school students’ mathematical reasoning ability on the Pythagorean Theorem based on four indicators: proposing conjectures, performing mathematical transformations, providing logical justification, and drawing conclusions. A descriptive qualitative approach was employed involving 31 eighth-grade students of SMP Negeri 1 Raha selected through purposive sampling. Data were collected using an open-ended mathematical reasoning ability test related to the Pythagorean Theorem and supported by semi-structured interviews. Data analysis was conducted using Miles and Huberman’s interactive model, consisting of data reduction, data display, and conclusion drawing and verification. The results indicate that 6% of students demonstrated high mathematical reasoning ability, 8% were categorized as moderate, and 86% were classified as low. Most students experienced difficulties in formulating conjectures, transforming contextual problems into mathematical models, providing logical justification, and drawing valid conclusions. In conclusion, students’ mathematical reasoning ability on the Pythagorean Theorem remains relatively low. Therefore, instructional strategies that emphasize conceptual understanding, reasoning processes, justification, and reflective thinking are necessary to improve students’ mathematical reasoning abilities.

Creativity in problem-solving needs to be strengthened through a systematic thinking framework. This study aims to explore students' creative thinking patterns in solving mathematics problems based on computational thinking (CT). A descriptive qualitative approach was employed, involving three junior high school students in West Bandung Regency representing high, medium, and low levels of mathematical ability. Data were collected through semi-structured in-depth interviews and essay test focusing on four elements of CT (decomposition, pattern recognition, abstraction, and algorithmic thinking) and four indicators of creative thinking (fluency, flexibility, originality, and elaboration). The results revealed High-ability students demonstrated strong integration between CT and conceptual creativity. Medium-ability students exhibited strategic flexibility, although their symbolic representations were not yet stable. In contrast, low-ability students tended to rely on procedural approaches. This study confirms that CT can function as a systematic thinking framework to foster creativity in 21st-century mathematics learning. It also contributes theoretically to understanding the dynamic relationship between CT and mathematical creative thinking and practically to the design of pattern-based tasks that stimulate student creativity.

Creative thinking skills are essential 21st-century skills that students must master. One factor that can hinder the achievement of this skill is math anxiety. This study aims to describe students' creative thinking skills in relation to their level of math anxiety. The research method employed is a descriptive qualitative approach. This research was conducted at SMP Negeri 2 Ungaran with seventh-grade students as the research subjects. The research tools consisted of a mathematics anxiety questionnaire, a mathematics ability test, and interview guidelines. The data will be analyzed through the stages of reduction, presentation, and conclusion. The sampling technique used was purposive sampling, in which students with high and low levels of mathematics anxiety were selected. The research subjects selected were four students who had similar creative thinking abilities. The creative thinking process is characterized by fluency, flexibility, and novelty. Based on the research, students with low levels of math anxiety tend to be able to demonstrate fulfillment of creative thinking skill indicators. Meanwhile, students with high levels of math anxiety are not able to demonstrate fulfillment of creative thinking skill indicators. However, there are differences in the creative thinking process between students with high and low levels of math anxiety.

This study examines the creative thinking abilities of mathematics student teachers in solving geometry problems, analyzed through the lens of Adversity Quotient (AQ). The participants, categorized as climbers, campers, and quitters, displayed varying levels of creative thinking based on three indicators: fluency, flexibility, and novelty. Climber students achieved fluency and flexibility by producing multiple logos using two different methods but lacked novelty as their approaches relied on existing methods. Campers demonstrated flexibility by using two distinct approaches but failed to meet fluency and novelty criteria. Quitters only met the fluency indicator and were at the less creative level. None of the subjects fulfilled the originality indicator, highlighting a critical gap in creative thinking skills among the participants. These findings underline the importance of fostering creative thinking in mathematics education, especially for student teachers who will later nurture such skills in their students. Enhancing the quality of mathematics instruction by incorporating open-ended problems and promoting a culture of mathematical thinking is essential. This aligns with the educational aim to balance analytical and creative thinking as fundamental aspects of problem-solving in mathematics.

The purpose of this study was to describe the critical thinking process of students with Field-Independent (FI) and Field-Dependent (FD) cognitive styles when they solved the Two-Variable Linear Equation System (SPLDV) problem, which is based on the Polya step and the Facione critical thinking indicator. This research is qualitative descriptive. The instruments in this study are the GEFT Test, the SPLDV problem-solving test and the interview guidelines are the research instruments. The results of the study show that FI students are able to understand and analyze data independently and systematically, use logical inference to choose a solution strategy, and provide a thorough procedural explanation. They are also capable of self-verification, which shows strong self-control In contrast, FD students face difficulties in selecting important information, making preparations that rely on the teacher's example, and performing inconsistent completion steps. Since the evaluation stage of FD students still depends on external justification, they also show a lack of self-regulation. These results confirm that cognitive style affects the activation of critical thinking indicators at each stage of problem-solving. In addition, cognitive style also provides implications for the importance of adaptive learning based on students' cognitive characteristics.

Penelitian ini bertujuan untuk mengklasifikasikan emosi manusia berdasarkan suara menggunakan metode Dimensi Fraktal Higuchi dan algoritma K-Nearest Neighbours (KNN). Data yang digunakan terdiri dari 120 sampel suara yang mewakili enam jenis emosi, yaitu marah, jijik, takut, bahagia, sedih, dan terkejut. Setelah melalui tahap pre-processing, fitur suara diekstraksi menggunakan Discrete Wavelet Transform (DWT), kemudian dihitung nilai dimensi fraktalnya dengan metode Higuchi. Nilai-nilai tersebut kemudian digunakan dalam proses klasifikasi menggunakan algoritma KNN. Berbagai pengujian dilakukan dengan variasi nilai K dan K-max untuk menemukan akurasi terbaik. Hasil penelitian menunjukkan bahwa metode yang digunakan mampu mengklasifikasikan emosi dengan akurasi tertinggi mencapai 91,67%. Temuan ini menunjukkan bahwa pendekatan ini cukup efektif dalam mengenali emosi manusia berdasarkan suara dan dapat menjadi dasar bagi pengembangan sistem pengenalan emosi berbasis suara di masa depan.

Pengenalan sidik jari merupakan salah satu metode biometrika yang banyak digunakan dalam sistem identifikasi individu. Pola sidik jari berbeda pada setiap individu dan bersifat permanen seumur hidup, sehingga menjadikannya alat identifikasi yang efektif. Namun, dalam penerapannya, sidik jari dapat mengalami kerusakan atau alterasi, baik yang terjadi secara alami akibat luka, goresan, atau penyakit, maupun yang dilakukan secara sengaja untuk menghindari sistem identifikasi. Kondisi ini dapat menurunkan tingkat akurasi sistem pengenalan sidik jari. Oleh karena itu, diperlukan sistem pengenalan sidik jari yang andal dan lebih adaptif terhadap perubahan pada pola sidik jari. Penelitian ini bertujuan untuk mengklasifikasikan citra sidik jari, baik citra asli maupun citra yang telah teralterasi, menggunakan perhitungan dimensi fractal dengan metode Box Counting. Sebanyak 100 citra sidik jari digunakan dalam penelitian ini. Proses diawali dengan penajaman citra, konversi citra ke format grayscale, dan deteksi tepi menggunakan metode Canny. Hasil deteksi tepi kemudian digunakan dalam perhitungan dimensi fraktal. Nilai dimensi fraktal yang diperoleh selanjutnya digunakan dalam proses klasifikasi menggunakan algoritma K-Nearest Neighbor (K-NN) dengan skema k-Fold Cross Validation. Hasil penelitian menunjukkan bahwa akurasi tertinggi yang dicapai adalah 83% menggunakan 4-Fold Cross Validation pada nilai K = 3 dan K = 5 untuk jumlah tetangga terdekat. Metode ini diharapkan dapat menjadi salah satu solusi alternatif dalam pengenalan sidik jari berbasis citra yang lebih adaptif terhadap perubahan pola sidik jari.
