Dear @Ahmad, I think that pBL courses enable students of Engineering to investigate closely some real life applications in their field, and thus are very essential and important; in addition, this is a good chance for the students to interact with their professors, the employers, and with other pairs. The following link is the website of the Aalborg Centre for Problem Based Learning in Engineering Science and Sustainability under the auspices of UNESCO that contains interesting material:

Dear @Ahmad, "Problem-Based Learning (PBL) is an educational approach that is learner focused. The focus shifts from a method of instruction that is teacher driven and led to one where the student is empowered to conduct self-directed learning. The learner is mentored and encouraged to conduct research, integrate what is learned, and apply that learning to develop a viable solution to an ill-defined problem"! It is a good master thesis!

As it is mentioned in @Abedallah's link: "Universities should take an active role in educating engineers and scientists that are able to participate in and contribute to the development of sustainable solutions to present and emerging social, economic and environmental challenges.!
