<![CDATA[This study aims to develop and examine the effectiveness of a bilingual (Arabic–Indonesian) interactive pictorial dictionary based on audio QR codes in improving students’ vocabulary mastery. This study employed a Research and Development (R&D) approach using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The subjects of this study were 21 fourth-grade students (Class IV A) at MI Raudlatul Qur’an Batam. Data were collected through expert validation, student response questionnaires, and pretest and posttest assessments. The validation results indicated that the product achieved an average score of 93%, categorized as “very feasible.” The effectiveness test results showed an improvement in the students’ average scores from 19.05 to 55.71. The N-Gain analysis revealed a score of 0.45, which falls into the moderate category. Furthermore, the paired sample t-test results showed that the calculated t-value (5.81) was greater than the t-table value (2.086), indicating a significant difference between pretest and posttest results. These findings indicate that the interactive pictorial dictionary based on audio QR codes is effective in improving students’ vocabulary mastery. This study contributes to the development of innovative, interactive, and technology-based Arabic language learning media that align with the needs of learning in the digital era.
