It is research and development using the 4D (define, design, develop, and disseminate) model to learn environmental change materials and augment environmental literacy. We carried out the research on tenth graders Mia SMA Negeri 1 Tabukan Utara, Sangihe. The research aims to: · Define the validity of learning devices using the project-based learning (PjBL) model, · Define the practicality of learning devices using the project-based learning (PjBL) model, · Define the effectiveness of learning devices using the project-based learning (PjBL) model. We collected data from 15 students in the first trial test and 60 students in the second one. The data were then validated by referring to lesson plans, E-LKPD, tests, and model attractiveness. Additionally, we also collected data on student pretest and posttest, skills, and concerns about the environment. The results demonstrated that learning devices using project-based learning (PjBL) to learn environmental change materials were reliable and effective for elevating students’ knowledge, skills, and environmental literacy.
