Teaching Methods

1- Theoretical classes where the presentation of the fundamental concepts, assumptions and methods of analysis is followed by the solution and analysis of application problems. These problems can be of an introductory type or more complex exam like problems.

2- Practical classes where application problems with a examination complexity level are presented. These problems are solved and analyzed by the students working by themselves. The lecturer must clarify the student’s doubts and promote the critical analysis of the solution methods and results.

3- Tutorials at the lecturer office for students presenting more difficulties and for additional or more advanced questions.
