Is often confused with problem-based learning. This may be partly because both methods are sometimes referred to by the acronym PBL. Though they are similar, there are a few key differences between problem and project-based learning.

Both PBLs involve students working to answer questions or solve problems. In both models, students are given complex problems with no clear solution and are asked to come up with an original idea.

The main difference between problem and project-based learning is in the product students created. In a problem-based learning lesson, students are simply developing a solution to a problem. With project-based learning, students must extend their ideas and complete an entire project.

Project-based learning is typically more in-depth and takes longer. While teachers might use a problem-based approach as a jumping-off point or only for a single lesson, project-based learning takes several weeks. As such, project-based learning usually involves more complex problems and is designed to challenge students more than problem-based learning.
