[English]: This study investigates the relationship between students' mathematical resilience and their learning styles and gender. Employing a non-experimental comparative design and survey methodology, the study utilized mathematical resilience and learning style questionnaires as data collection instruments. The study's sample consisted of 62 fifth-grade elementary school students from Stabat City, North Sumatra Province. Sampling was conducted using the probability proportional sampling technique, resulting in 32 female and 30 male students. Data analysis employed a two-way ANOVA test to examine the impact of two independent variables (learning style and gender) on the dependent variable (mathematical resilience). The findings revealed that the visual learning style was the predominant learning style among students. Furthermore, the study demonstrated a significant correlation between learning styles and mathematical resilience, suggesting that variations in learning styles significantly influence mathematical resilience. In contrast, gender was found to have no discernible impact on mathematical resilience. Additionally, the analysis indicated no interaction between learning style and gender in influencing mathematical resilience. These findings imply that learning styles independently influence mathematical resilience, without any moderating effect of gender. The implications of this study suggest that when developing teaching strategies to enhance mathematical resilience, it is advisable to prioritize individual learning styles rather than differentiating based on gender. [Bahasa]: Penelitian ini bertujuan untuk menguji resiliensi matematis siswa dalam kaitannya dengan gaya belajar dan jenis kelamin mereka. Dengan menggunakan desain komparatif non-eksperimental dan metodologi survei, penelitian ini menggunakan kuesioner resiliensi matematis dan gaya belajar sebagai instrumen pengumpulan data. Subjek penelitian terdiri dari 62 siswa sekolah dasar kelas lima dari Kota Stabat, Provinsi Sumatera Utara. Pengambilan sampel dilakukan dengan menggunakan teknik probability proportional sampling, menghasilkan 32 siswa perempuan dan 30 siswa laki-laki. Analisis data menggunakan uji ANOVA dua arah untuk menguji dampak dari dua variabel independen (gaya belajar dan jenis kelamin) terhadap variabel dependen (resiliensi matematis). Temuan penelitian mengungkapkan bahwa gaya belajar visual adalah gaya belajar yang paling umum (dominan) di antara siswa. Lebih jauh lagi, gaya belajar menunjukkan dampak yang signifikan pada resiliensi matematis, yang menunjukkan bahwa variasi dalam gaya belajar memberikan kontribusi secara substansial pada tingkat resiliensi matematis. Sebaliknya, tidak ditemukan pengaruh jenis kelamin pada resiliensi matematis. Selain itu, analisis menunjukkan tidak adanya interaksi antara gaya belajar dan jenis kelamin dalam mempengaruhi resiliensi matematis. Temuan ini menunjukkan bahwa gaya belajar secara mandiri mempengaruhi resiliensi matematis, tanpa moderasi apa pun oleh jenis kelamin. Implikasi dari penelitian ini menunjukkan bahwa ketika mempertimbangkan strategi pengajaran untuk meningkatkan resiliensi matematis, penekanan dapat diberikan pada gaya belajar individu tanpa perlu membedakan berdasarkan jenis kelamin.

This study aims to analyze the Computational Thinking (CT) abilities of prospective mathematics teacher students enrolled in the Teacher Professional Education Program at Universitas Islam Sumatera Utara. Using a descriptive quantitative approach, CT abilities were examined based on four main indicators: decomposition, pattern recognition, abstraction, and algorithmic thinking. Data were collected through contextual open-ended tests, perception questionnaires, and limited interviews involving 24 PPG students. The results showed that, in general, students' CT abilities fell into the moderate category, with the highest achievement in pattern recognition and the lowest in abstraction. Most students had never received explicit instruction in CT, yet acknowledged that this approach helped them solve mathematical problems more systematically. These findings highlight the importance of explicitly integrating CT skills into mathematics education curricula through problem-based and digital literacy-oriented learning approaches. The study recommends strengthening instructional strategies to develop students’ systematic and logical thinking abilities as future mathematics educators.

Hasil menunjukkan bahwa kelompok eksperimen mengalami peningkatan signifikan, dengan N-Gain literasi (0.449) dan numerasi (0.439) lebih tinggi dibanding kelompok kontrol (0.268 dan 0.236). Selain itu, PK berpengaruh signifikan terhadap numerasi, tetapi tidak terhadap literasi. Penelitian ini merekomendasikan integrasi PBL dalam kurikulum untuk meningkatkan keterampilan siswa serta penelitian lanjutan terkait motivasi dan konteks sosial-budaya. PBL terbukti sebagai pendekatan inovatif yang relevan bagi peningkatan kualitas pendidikan di Indonesia. Abstract Literacy and numeracy skills are essential for individuals to reach their full potential, lead meaningful and productive lives, and participate fully in society. This study aims to examine the effectiveness of Problem-Based Learning (PBL) in enhancing the literacy and numeracy skills of primary school students in Medan, Indonesia. Employing a quasi-experimental design, the study involved 37 students in the experimental group (PBL) and 35 students in the control group (conventional learning). Data were collected through prior knowledge (PK) tests, as well as literacy and numeracy assessments, and analyzed using two-way ANOVA. The results revealed that the experimental group showed significantly greater improvement, with N-Gain scores for literacy (0.449) and numeracy (0.439) exceeding those of the control group (0.268 and 0.236, respectively). Additionally, prior knowledge had a significant effect on numeracy outcomes, but not on literacy. The study recommends integrating PBL into the curriculum to enhance student skills and encourages further research on motivational and sociocultural factors. PBL is demonstrated to be an innovative and relevant approach for improving the quality of education in Indonesia.
