This research aimed to determine the effects of a problem-based learning model with environmental literacy-oriented on the elementary school students' narrative writing skills. Using the quasi-experimental method, this research employed a non-equivalent control group design. The research participants were 50 fifth-grade students of Islamic Elementary School (MI) Darul Qirom, consisting of 25 students in the experimental class and 25 students in the control class. The data were collected using a test instrument consisting of five questions about writing narratives. The data were then analyzed using the independent sampel t-test with the assistance of the SPSS application. The data analysis showed a significant difference between the class that used the problem-based learning model with environmental literacy-oriented and the class that used the conventional learning model, with a significant value (2-tailed) of 0.006 < 0.05. In this study, the average post-test score for the experimental class after the treatment was 5.52 higher than the control class (78.2 > 72.68). It can be concluded that the environmental literacy-oriented problem-based learning model has a significant effect on the narrative writing skills of elementary school students.
