Abstract

This study aims to explore primary school students' mathematical connection skills in solving mathematical problems. Mathematical connection ability is the ability of students to connect and integrate different mathematical concepts effectively. This research used a qualitative approach with descriptive method. The sample consisted of 20 grade V students at SDN 31 Bontomacinna. Data were collected through tests and interviews, and analysed using quantitative and qualitative approaches. The results showed that students' mathematical connection ability varied, with some students having excellent, good, sufficient, deficient, and very deficient abilities. Data analysis showed that students with better mathematical connection ability tended to obtain higher scores in solving mathematics problems. Students' mathematical connection skills also influenced their overall understanding of mathematical concepts and ability to see connections between topics in mathematics, outside mathematics, and everyday life. This research makes an important contribution to the development of more effective mathematics curriculum and learning strategies. By understanding better about students' mathematical connection abilities, educators can design more interesting and enjoyable learning experiences, and improve students' ability to solve mathematical problems. The implementation of Merdeka Curriculum in Indonesia is also expected to support the development of students' mathematical connection skills at the primary school level.

Abstract

Pembelajaran daring telah menjadi solusi utama dalam meningkatkan akses pendidikan, terutama di daerah terpencil yang memiliki keterbatasan infrastruktur. Namun, implementasi pembelajaran daring di daerah tersebut masih menghadapi berbagai kendala, seperti minimnya akses internet, keterbatasan perangkat, serta rendahnya kesiapan guru dan siswa dalam memanfaatkan teknologi digital. Penelitian ini bertujuan untuk menganalisis tantangan utama dalam implementasi pembelajaran daring di daerah terpencil serta mengeksplorasi solusi yang dapat diadaptasi agar proses pembelajaran lebih efektif dan inklusif. Metode penelitian yang digunakan adalah kualitatif dengan pendekatan fenomenologis, di mana data dikumpulkan melalui wawancara mendalam, observasi lapangan, dan analisis dokumentasi. Hasil penelitian menunjukkan bahwa keterbatasan infrastruktur merupakan hambatan utama yang menyebabkan rendahnya efektivitas pembelajaran daring. Selain itu, sebagian besar guru dan siswa mengalami kesulitan dalam mengakses dan memahami materi daring tanpa adanya bimbingan langsung. Sebagai solusi, penelitian ini merekomendasikan pendekatan blended learning berbasis komunitas, yang mengombinasikan pembelajaran daring dengan sesi tatap muka di pusat-pusat belajar lokal. Selain itu, pengembangan konten pembelajaran yang lebih kontekstual, seperti materi berbasis bahasa lokal dan metode interaktif berbasis audio dan video, terbukti meningkatkan keterlibatan siswa hingga 75%. Dengan strategi yang lebih adaptif terhadap kondisi daerah terpencil, pembelajaran daring dapat dioptimalkan untuk meningkatkan akses pendidikan yang lebih inklusif dan berkelanjutan.

Abstract

This study aims to analyze the effectiveness of implementing the Project Based Learning (PjBL) model in the CAD/CAM course to improve the learning outcomes of Mechanical Engineering students at Universitas Tomakaka. Using a quasi-experimental method with a pretest-posttest control group design, the study involved 60 fourth-semester students divided equally into an experimental group taught with PjBL and a control group taught using conventional methods. Data were collected through cognitive tests, project assessments, and affective rubrics, then analyzed using normality and homogeneity tests, independent t-tests, and N-Gain scores.The findings showed that the experimental group experienced significant improvement in cognitive learning outcomes, with higher posttest scores and moderate to high N-Gain values, compared to the control group, which demonstrated only low improvement. Psychomotor outcomes also revealed a strong positive effect, with the PjBL group outperforming the control group in 3D modeling accuracy, design quality, and software utilization. Furthermore, affective outcomes highlighted that the experimental group exhibited greater teamwork, communication, and participation, supported by significant statistical differences.These results confirm that PjBL is an effective learning model that enhances not only cognitive and technical competencies but also essential soft skills required by the engineering profession. The integration of PjBL in CAD/CAM courses provides a holistic learning experience that prepares students to face the challenges of Industry 4.0. This study recommends broader implementation of PjBL in technical education, supported by adequate facilities and collaboration with industry to ensure the relevance and sustainability of project-based curricula.
