The study aims to investigate the effect of project-based learning on students' motivation and their self-efficacy. Project-based learning is an instructional technique which has been proven to be effective because it allows students to play an active role in their own learning process. By participating in a project-based learning model, students are able to construct their own knowledge and reflect upon their learning projects, resulting in increased motivation and self-efficacy. In this particular study, 79 students were distributed among 13 teams and each team shared a common goal. Each team was given a project, and every student in each team was assigned a task that would help the team achieve the preset goal. The project in this study was a video production that required students to work together in collaborative ways. The results of this study support the idea that project-based learning has a positive influence in students' motivation and is able to enhance their cooperation skills as well. Furthermore, student responses in the survey taken after the project shows that the students' perceptions toward project-based learning are very positive. Further research is suggested to find the effects of project-based learning on students' motivation and self-efficacy in different levels, grades, or age groups.
