Three Project Based Learning Resources: Free Online Resources for Student Collaboration and Problem Solving Project based learning using all or any of the three online resources offers a dynamic approach to teaching in which students explore real-world problems and challenges. Project Based Learning (PBL) provides opportunities for students to collaborate as they solve challenging problems. This problem solving strategy is guided by open-ended questions which drive student lead investigative processes. Student groups research the problem, collect data, and draw conclusions based on their findings. An example of a complicated PBL is assigning student groups to visit ten stations around the classroom. At each station there are different items. The challenge is to determine the socio-economical forces that drove those products into being made.
