Abstract

Introducing children to mathematics is an urgent matter. Most children in the B-Luke class at TK Kristen Kalam Kudus Pematang Siantar struggle to understand number concepts, even though they can count. Therefore, this study aims to use flashcards as a playful medium to help children understand number concepts from 1 to 20. This is a classroom action research with two cycles. The subjects were 11 children from the B-Luke class. Data were collected through observation, post-class tests, and documentation. The data analysis shows that the initial concept understanding ability, which was predominantly at the Developing (MB) level (55%), increased to an average of Very Well Developed (BSB) at 64%. This demonstrates an improvement in understanding number concepts through the use of flashcards and playful methods.

Abstract

Rendahnya pemanfaatan teknologi dan literasi digital peserta didik menjadi permasalahan utama dalam pembelajaran Matematika di SMP Bina Jaya Banguntapan. Keterbatasan sarana teknologi, metode pembelajaran yang masih konvensional, serta minimnya media visual interaktif menyebabkan rendahnya partisipasi dan motivasi belajar siswa. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi digital dan kreativitas peserta didik melalui pelatihan pembuatan media pembelajaran Matematika berbasis digital berupa infografis, poster, dan animasi. Metode pelaksanaan kegiatan menggunakan pendekatan pelatihan berbasis praktik yang terdiri atas empat tahap, yaitu persiapan, pelaksanaan inti, evaluasi, dan publikasi. Pelatihan dilaksanakan dengan memanfaatkan aplikasi Canva sebagai media desain yang mudah diakses dan sesuai dengan karakteristik peserta didik. Hasil kegiatan menunjukkan adanya peningkatan pemahaman konsep Matematika, keterampilan desain media pembelajaran digital, serta partisipasi aktif peserta didik selama proses pembelajaran. Selain itu, siswa mampu menghasilkan media pembelajaran digital yang menarik dan sesuai dengan materi yang dipelajari. Simpulan dari kegiatan ini adalah bahwa pelatihan pembuatan media pembelajaran digital efektif dalam mendukung pembelajaran Matematika yang lebih interaktif, kreatif, dan menyenangkan, serta berkontribusi pada penguatan literasi digital peserta didik.

Abstract

This study originated from the low numeracy skills of students, in which only 5 out of 33 students were able to solve the problems correctly. The purpose of this study was to improve students’ numeracy skills through the implementation of the Teams Games Tournament (TGT) model using Mathematics Domino Cards (DoMat) as learning media in Grade III of SD Negeri Salit. The research subjects consisted of 33 students, including 15 female students and 18 male students. This study employed Classroom Action Research. Data were collected through formative tests to measure students’ numeracy skills and non-test techniques in the form of observation sheets to examine learning activities. Data analysis techniques included quantitative descriptive analysis for test results and qualitative descriptive analysis for observation data. The results showed an increase in the percentage of students’ mastery of numeracy skills from 33.33% in the pre-cycle to 66.66% in Cycle I, and further increased to 87.87% in Cycle II. These findings indicate that the TGT model with DoMat cards is effective in improving students’ numeracy skills.
