Teaching methodologies (including evalution)

The C.U. will be ministered with theoretical presentations and practical applications of the dealt subjects, to which didactical materials, variant in nature, will be made available to students. Worksheets will also be made available to students with problems to be solved in group, students that at the end will have to present and discuss the conclusions with their colleagues. The proposed works will have to be solved in the classroom with the possibility to reflect over the given solutions, in an autonomous work and subsequent delivery of the reformulated solutions. Evaluation modes and correspondent reflection: two written tests, each with 50% weighting in the final grade.
