This research is motivated by the difficulties experienced by students with mild intellectual disabilities, specifically in their low vocabulary mastery. A learning media in the form of a fable book using the concept of an audio movable book was utilized to enhance the vocabulary of students with mild intellectual disabilities. The objective of this study is to analyze the effectiveness of using a fable book with the concept of an audio movable book in improving the vocabulary of students with mild intellectual disabilities. This research method adopts a quantitative approach with a pre-experimental type and a one-group pretest-posttest design. The sample consists of 6 students with mild intellectual disabilities, comprising 2 students from SDLB level, 1 student from SMPLB level, and 3 students from SMALB level, who exhibit fluent speech but have low vocabulary. Data collection techniques employed include tests, and non-parametric statistical data analysis techniques using the Wilcoxon test. Based on the research results using the Wilcoxon Match Pair Test formula with two-sided testing, the alternative hypothesis (Ha) and null hypothesis (H0) are rejected. The Wilcoxon Match Pair Test yields a value of 2.2, which is greater than the critical value of 1.96 at 5% significance level. Additionally, the test using SPSS V 25.0 yields Asymp.Sig.(2-tailed) = 0.028, which is smaller than α = 5%, indicating that the fable book media with the concept of an audio movable book is effective in improving the vocabulary of students with mild intellectual disabilities.
