Stick Board Media to Improve Conceptual Understanding of Numbers 1–10 for Grade 1 Students with Visual Impairment at SLB A Bina Insani

This study aims to improve the conceptual understanding of numbers 1–10 among grade 1 students with visual impairment through the use of stick board media. The study is based on the limited ability of visually impaired students to grasp basic numerical concepts due to the lack of appropriate tactile learning media. This research employed a Single Subject Research (SSR) method with an A1–B–A2 design. The subject was a first-grade student with visual impairment at SLB A Bina Insani. Data were collected through repeated observations across three phases: baseline 1 (A1), intervention (B), and baseline 2 (A2). The results showed a significant improvement in the student’s conceptual understanding. In the baseline phase (A1), the average score was 21.2. During the intervention phase (B), the score increased to 58.6, and in the second baseline phase (A2), it reached 85.71, indicating sustained improvement after the intervention. These findings indicate that stick board media is effective in enhancing students’ understanding of basic numerical concepts. The use of tactile-based media provides meaningful learning experiences for students with visual impairment. This study implies that teachers should utilize personalized, tactile instructional media and design flexible learning activities. Additionally, the integration of stick board media into the mathematics curriculum in special schools is recommended to support foundational numeracy development.
