Learning effectiveness influences interrelated components: teachers, students, objectives, methods, models, materials, learning tools (media), and evaluation. This research aims to determine the effectiveness of learning to write fantasy texts for class VII students at SMP Negeri 10 Jambi City using the PjBL model assisted by animated videos. This research was carried out at SMP Negeri 10 Jambi City. The type of research used in this research is Quasi-Experimental research with a non-equivalent control group design. The population in this study were all class VII students of SMP Negeri 10 Jambi City. The sample in this study was class VII E, the experimental class, and class VII B, the control class, with 25 participants in each class. The technique used is a simple random sampling technique. The analysis results in this study show that learning to write fantasy texts is effective using the PjBL model assisted by animated videos. It is based on the average data obtained by students in class VII E (experimental class) who were treated using the PjBL model assisted by animated videos; the number was 69.44, while in class VII B (control class) who were treated with the conventional model, the number was 54.40. In addition, carrying out the t-test produces t count ≥ t table (5,087 ≥ 2,956). Based on the data above, it can be concluded that using the project-based learning model assisted by animated videos is effectively applied in learning to write fantasy texts for class VII students at SMP Negeri 10 Jambi City.
