Teaching method

Theoretical sessions in the classroom with data show to present the theoretical topics, but in which the debate with students is a central objective. Theoretical-practical sessions to carry out work proposed by the teacher. Technical visits.

If there are ERASMUS students enrolled who do not speak Portuguese, the classes will be taught in English.

Evaluation method

Two theoretical tests (tests 1 and 2) with a weight of 25% each in the final classification.

Two theoretical-practical team works (works TP1 and TP2) with a weight of 25% each in the final classification.

Approval with a minimum classification of 9.5 values (20 values scale).
