The arguments of the authors converge to the importance of the contact with real problems, simulated or in real time, and the challenge to look for solutions to these problems. This approach is known as problem based learning (PBL). It is a constructivist approach to learning, where the students start the exploration of a new content with the observation of the reality, identification of key factors that leads to the structuring of the theory. Based on the theory, the students are asked to formulate hypotheses to solve the problem, then apply and observe the consequences of it. By going through this process, the student can learn by acting on what he already knows and building new concepts and ideas through the interaction with experience, literature (theory) and the analysis of different point of views.
