Abstract

Pembelajaran matematika di sekolah dasar sangat penting untuk kemampuan dasar anakdalam mengenal hal angka dan perhitungan yang bertujuan untuk meningkatkan keterampilan kognituf para siswa. Dengan alat peraga, maka hal-hal yang abstrak dapat bisa disajikan dalam bentuk model-model, sehingga siswa dapat memanipulsi objek tersebut dengan cara dilihat, dipegang, diraba, diputar balikkan, agar lebih mudah memahami matematika. Sosialisasi ini merupakan sosialisasi yang berbasis PAR (Participatory Action Research) dan berbasis demostrasi. Kegiatan sosialisasi alat peraga matematika diselenggarakan pada tanggal 19 Juni 2023. Kegiatan ini dilakukan di ruangan kelas III SDN 067244. Sosialisasi alat peraga Matematika merupakan salah satu implementasi ilmu pengetahuan dan teknologi oleh Prodi Pendidikan Guru Sekolah Dasar Universitas Katolik Santo Thomas Medan. Melalui kegiatan ini peserta kegiatan dapat menguasai cara memakai alat peraga bilangan bulat petak pintar sehingga dapat memahami konsep bilangan bulat dengan lebih mudah. Sosialisasi kegunaan alat peraga telah berhasil di lakukan oleh tim mahasiswa PGSD kepada guru dan siswa,

Abstract

This study aims to determine the effect of the CORE (Connecting, Organizing, Reflecting, Extending) learning model assisted by visual media on student learning outcomes in the IPAS subject for Grade IV at SD Negeri 060954 Medan Marelan. The research employed a One Group Pretest-Posttest Design with tests and questionnaires as data collection instruments. A total of 26 students participated as the research sample. The CORE model was implemented through structured steps that guided students to connect prior knowledge with new concepts, organize ideas, reflect on information, and deepen understanding through assignments. The results showed a significant improvement in the students’ average scores from 46.92 (pretest) to 85.34 (posttest), with 23 out of 26 students achieving mastery learning. The t-test analysis yielded tcount = 2.156 > ttable = 2.064, and the correlation coefficient was r = 0.403 > rtable = 0.388, indicating a moderate and significant relationship between the CORE model implementation and student learning outcomes. Furthermore, questionnaire responses revealed that students enjoyed the use of visual media, as it made learning more engaging, concrete, and easier to understand. These findings support cognitive learning theory and previous research showing that the CORE model enhances student engagement and conceptual understanding. It can be concluded that the CORE learning model assisted by visual media significantly improves student learning outcomes in IPAS, while fostering collaborative and meaningful learning experiences.
