Difference between Project-Based and Problem-Based Learning
While Project-Based Learning and Problem-Based Learning share much in common, they are two distinct approaches to learning. In Project-Based Learning, students have a great deal of control of the project they will work on and what they will do in the project. The project may or may not address a specific problem. In Problem-Based Learning, a specific problem is specified by the course instructor. Students work individually or in teams over a period of time to develop solutions to this problem. This instructional approach is widely used in Architecture Education, Business Education, Medical Education, and in other situations where "case study" methods provide a useful focus in teaching/learning.
Note: This site lists many projects from a variety of other sites in many disciplines. Many of these projects can be transformed into problems. Its a good starting place for idea generation.
