This study examines the integration of Project-Based Learning (PjBL) and the TikTok Duet Challenge to improve speaking skills, particularly fluency and comprehensibility, among eleventh-grade students at MA DDI Parigi. The research employed a pre-experimental design using a one-group pre-test and post-test approach involving 15 students. Data were analyzed using a t-test to determine the effectiveness of the treatment, with the results showing that the t-counted value (11.83) exceeded the t-table value (1.761). The findings indicate a significant improvement in students’ speaking performance, as reflected in the increase of the mean score from 36.66 in the pre-test to 61.66 in the post-test. The treatment was conducted over six meetings and covered topics such as describing people and expressing agreement and disagreement through TikTok duet activities. The results demonstrate that the integration of PjBL and TikTok effectively enhances students’ speaking fluency, confidence, and opportunities for authentic, real-world communication, thereby addressing limitations identified in previous speaking skill studies.
