This study aims to examine the effectiveness of the NovelToon application as a learning medium in improving the drama script writing skills of eleventh-grade students at SMA Negeri 18 Bone. The primary issue addressed in this study is the students’ low initial writing ability, which was attributed to the use of conventional learning media that were less effective in stimulating imagination and creativity. The research employed a quantitative approach using a Pre-experimental design with a One-Group Pretest–Posttest model. The sample consisted of 34 students from class XI.F3, selected through a specific sampling technique. Data were collected through observation, written tests (drama script writing), and documentation. The data were then analyzed using descriptive and inferential statistics with the assistance of IBM SPSS Statistics version 22. The findings revealed a significant improvement in students’ learning outcomes. In the pretest stage, the mean score was only 58.11 with a standard deviation of 7.93, and nearly half of the students (49.8%) were classified in the “Poor” category. After the implementation of the NovelToon application, the mean score increased substantially to 86.79, while the standard deviation decreased to 4.91. The majority of students (87.9%) achieved the “Very Good” category, and no students remained in the “Fair” or “Poor” categories. The results of the Paired Samples t-Test showed a significance value (2-tailed) of < 0.001, which is lower than 0.05 (p < 0.05). Therefore, H₀ was rejected and Hₐ was accepted. These findings indicate that the use of the NovelToon application has a significant and positive effect on improving students’ drama script writing skills. This effectiveness is supported by the availability of visual and narrative stimuli within the application, which help students visualize scenes and systematically organize the intrinsic elements of drama. Furthermore, the decrease in the standard deviation indicates that the application was also effective in reducing the achievement gap among students in the classroom.
