Abstract

Classroom Action Research aims to improve vocabulary acquisition among first-grade students using flashcards at SD Negeri 060912 Medan for the 2024/2025 academic year. Initial observations revealed that students' understanding of letters and words was not meeting developmental expectations. Only 8 out of 21 students were able to read well, while most struggled with letter recognition and word reading. To address this issue, the research employed flashcards to enhance early reading skills. The study involved 21 students (12 boys and 9 girls) as subjects. Research instruments included observation sheets, student worksheets, and pretests and posttests for cycles 1 and 2. The results showed a significant improvement in vocabulary acquisition: in cycle I, 47.61% of students had not reached the Minimum Completeness Criteria (KKM), whereas in cycle II, 85.71% of students surpassed the KKM. This indicates that using flashcards effectively improved students' vocabulary acquisition.
