Teaching Methodologies and Assessment Criteria |
The curricular unit is structured in two parts. In the first part, the fundamentals and concepts are lectured with the support of multimedia slides. Additional information is written on the board. In the second part, computational tools (development of computer codes and use of commercial packages) are applied to solve practical engineering problems.
Evaluation is continuous and carried out in two stages: (i) a written test (TE); and (ii) a set of assignments (TP), evaluating different aspects of the competencies acquired by the students. The learning process classification is NFA=0.3xTE+0.7xTP. Approval occurs when, cumulatively, NFA>=10, TE>=8, and TP>=6. The condition for exam access is TE>=8 and TP>=6. The exam evaluation is based on a
written test (NE) and the assignments carried out during the semester (the assignments are only done once). The exam classification is NFE=0.3xNE+0.7xTP.
