The Effectiveness of Using Number Chart Media to Improve the Ability to Recognize Numbers 1–10 in Second Grade Deaf Students at SLB Negeri Mesuji

Abstract

This research was motivated by the identification of a second-grade deaf student at SLB Negeri Mesuji who had difficulty recognizing numbers. According to the curriculum, students are expected to recognize numbers before learning arithmetic and addition operations. However, although the teacher had already introduced counting and addition, conventional teaching methods were still predominantly used. In contrast, learning for deaf students should be conducted face-to-face, emphasize visual input, and rely heavily on visual media. Therefore, this study aimed to examine the effectiveness of number chart media in improving the ability to recognize numbers 1–10 in a second-grade deaf student at SLB Negeri Mesuji. This study employed a Single Subject Research (SSR) method with an A–B–A design, and the data were analyzed using visual graphic analysis. The results showed that the Baseline-1 (A1) phase was conducted in four sessions, with a mean level of 20%, 100% data stability, and a stable trend (=). The Intervention (B) phase was conducted in seven sessions, resulting in a mean level of 74.2%, a stability percentage of 85.7%, and an increasing trend (+). Furthermore, the Baseline-2 (A2) phase was conducted in six sessions, with a mean level of 95.8%, 100% data stability, and an increasing trend (+). Data overlap analysis showed 0% overlap between phases B/A1 and B/A2. Therefore, the research hypothesis was accepted, indicating that number chart media effectively improves the ability to recognize numbers 1–10 in second-grade deaf students at SLB Negeri Mesuji.
