EFEKTIVITAS PENGGUNAAN FLASHCARD DALAM MENGEMBANGKAN PEMAHAMAN GEOMETRI PADA ANAK USIA 4-5 TAHUN DI TKIT AN NAHL PONDOK MELATI

Abstract

This study aims to examine the effectiveness of using flashcard media in improving the understanding of geometric concepts among children aged 4-5 years at TKIT An Nahl Pondok Melati. The background of the research is based on the importance of introducing geometric concepts from an early age as a foundation for logical thinking and problem-solving in the future, as well as the challenges found in understanding geometry due to less engaging teaching methods. The research uses an experimental method with a Single Subject Research (SSR) design of the A-B-A’ type, involving five children from group A as subjects. Data were collected through observation and documentation, then analyzed descriptively using the percentage of children's skill development. The results showed a significant increase in geometric understanding, from an average of 28% in the baseline-1 phase to 79% in the baseline-2 phase after the flashcard intervention. In addition, the children demonstrated high enthusiasm and active participation during the learning process. These findings confirm that flashcards are effective as an interactive and enjoyable geometry learning medium for early childhood and can serve as an alternative teaching method at the kindergarten level.
