This research aims to analyze differences in mathematical understanding of fourth grade students at UNISMUH Makassar Labschool based on their learning styles. The background to this research stems from various problems found in the field, such as students' low mathematical understanding, teachers' lack of understanding of learning styles, and the lack of research related to learning styles at the elementary school level. This research uses a descriptive qualitative approach with phenomenological methods to explore students' subjective experiences in understanding integer material based on visual, auditory and kinesthetic learning styles. The research results show that students with an auditory learning style tend to excel in solving problems verbally and narratively, while visual students are better at understanding basic concepts through pictorial representations, but have difficulty in advanced applications. Kinesthetic students show moderate comprehension, depending on the physical activity and props used. Although differences were found in the level of mathematical understanding between learning styles, these differences were not statistically significant. Thus, learning style is not the only determining factor in students' mathematical understanding, but it still needs to be considered in planning more adaptive learning.

Background: Metacognition significantly influences students' effectiveness in solving mathematical problems. Variability in metacognitive patterns among students is shaped by factors such as adversity quotient (AQ) and gender.Aim: This research aimed to explore metacognitive patterns in mathematical problem-solving among students majoring in mathematics at Universitas Muhammadiyah Jakarta, with a specific focus on differences due to AQ and gender.Method: Adopting a qualitative approach with a phenomenological framework, this study included six students (three males and three females) from the 2021–2022 academic year. These students represented different AQ categories: climber, camper, and quitter. Data collection involved tests, observations, and interviews.Results: The investigation showed that students with a climber AQ, irrespective of gender, adeptly utilized all metacognitive knowledge facets: declarative, procedural, and conditional. In contrast, male campers engaged primarily in declarative and procedural knowledge, while male quitters demonstrated negligible engagement. Female campers predominantly employed declarative knowledge, occasionally integrating conditional knowledge. Female quitters, however, did not exhibit significant usage of metacognitive knowledge. Regarding metacognitive regulation—planning, monitoring, and evaluation—students identified as climbers displayed proficiency across all these aspects, regardless of their gender.Conclusion: The study underscores the influence of AQ and gender on metacognitive patterns in mathematical problem-solving, noting an exception in climbers who consistently exhibit effective metacognition. These insights could guide educational strategies to bolster metacognitive skills in the context of mathematics education.

Penelitian ini bertujuan untuk menganalisis penerapan pendekatan Realistic Mathematics Education (RME) dalam meningkatkan hasil belajar siswa pada materi operasi hitung penjumlahan dan pengurangan di kelas sekolah dasar. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus, yaitu siklus I dan siklus II, dengan tahapan perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Hasil penelitian menunjukkan bahwa pendekatan RME yang menghubungkan materi matematika dengan konteks kehidupan sehari-hari mampu meningkatkan hasil belajar siswa secara signifikan. Pada pra-siklus, hanya sekitar 50% siswa yang berhasil menyelesaikan soal dengan benar. Namun, setelah penerapan RME pada siklus I, hasil belajar meningkat menjadi 70%, dan pada siklus II mencapai 90%. Refleksi yang dilakukan setelah setiap siklus memungkinkan guru untuk menyesuaikan metode pembelajaran sesuai dengan kebutuhan siswa. Temuan ini konsisten dengan penelitian sebelumnya yang menunjukkan bahwa pendekatan berbasis konteks dapat meningkatkan motivasi dan pemahaman siswa dalam belajar matematika. Berdasarkan hasil penelitian ini, disarankan agar pendekatan berbasis konteks seperti RME diterapkan lebih luas dalam pembelajaran matematika, didukung dengan penggunaan alat peraga yang bervariasi dan evaluasi berkelanjutan melalui refleksi.
