<![CDATA[This study aims to analyze the influence and effectiveness of a project-based collaborative learning model on the enhancement of students' civic responsibility. This research employs a quantitative approach with a pre-experimental design, specifically utilizing the one-group pretest-posttest method. The subjects of this study were 8th-grade students at SMP Shohibul Barokah. Data collection was conducted through questionnaires, while data analysis involved statistical testing, including the Kolmogorov-Smirnov normality test, the paired sample t-test for hypothesis testing, and the N-Gain calculation. The results indicate that the implementation of the project-based collaborative learning model significantly influences students' civic responsibility. This is evidenced by the hypothesis test results, which yielded a significance value (Sig. 2-tailed) of < 0.001. As this value is considerably lower than the established significance level ($\alpha = 0.05$), the null hypothesis H0 is rejected, and the alternative hypothesis H1 is accepted. However, the level of effectiveness remains in the low category, with an N-Gain score of 0.158. Nevertheless, these findings demonstrate a measurable improvement in students' civic responsibility following the application of the project-based collaborative learning mode.]]>
