Abstract This study aims to analyze the effect of applying the inquiry-based learning model on Arabic language learning outcomes among tenth-grade students at Wali Songo Sukajadi Senior High School in Central Lampung. The research employed a descriptive quantitative method, using a questionnaire as the primary data collection tool. A total of thirty students participated in this study, and the data were analyzed using Pearson correlation coefficient and the One-Sample Kolmogorov-Smirnov Test to assess the normality of data distribution. The results showed that the data followed a normal distribution, allowing for the application of parametric statistical tests. The Pearson correlation analysis revealed a very strong positive relationship between the implementation of the inquiry-based learning model and Arabic language learning outcomes, with a correlation coefficient of 0.960, indicating that the model accounts for 92.16% of the variance in student performance. This suggests a high level of effectiveness of the model in improving academic achievement. The study concludes that the inquiry-based learning model contributes to the development of critical thinking, enhances active student engagement, and improves comprehensive language skills. The study recommends wider implementation of this model in various educational contexts, supported by a conducive learning environment and well-trained teachers capable of effective execution.
