Teaching method

The teaching method in the theoretical-practical classes is essentially the oral exposition of the subjects, accompanied by drawings, diagrams and notes/summary made by the teacher using means of projection. The teacher presents standard problems and solves them in order to show the students the solution strategy.

The practical works are presented and the teacher defines a time period for their resolution outside the classroom, following the progress of the works.

Evaluation method

- Continuous assessment: presentation of two group works and a test (and/or exam).

- Obtaining frequency: realization of the group works.

- Presentation of Work 1 - End of April                                             (20% of the final classification)

- Presentation of Work 2 - Mid May                                                  (20% of the final classification)

- Realization of the Test - Beginning of June (and / or the exam)     (60% of the final classification)

- Exemption of examination: weighted average ≥ 10.
