Métodos de ensino e atividades de aprendizagem

In theoretical-practical classes (TP) the program contents are exposed using active learning methodologies so that students achieve the learning objectives. In this way, the syllabus also includes the resolution of practical exercises for the application of theoretical concepts. Exercises are also proposed for autonomous resolution on the Moodle platform. All materials used in class and complementary to the Curricular Unit are available on the Moodle platform. Assessment is continuous and obtained through the completion of two tests throughout the semester and one research work (TPes). There is the possibility for students to repeat a test at exam time, if necessary.

In the laboratory classes (PL) 13 practical laboratory works are carried out that exemplify the syllabus, where students are asked to make reports and practical works that simulate industrial activity in the field of mechanical technology. The completion of these practical laboratory work is mandatory as well as the presence of students in laboratory classes.

The TP and PL classes have provided for the clarification of doubts using the Teams platform, whenever justified in supporting students

Obtenção de frequência

Continuous assessment presupposes mandatory attendance and may have a maximum percentage of absences of 15%.

Fórmula de cálculo da classificação final

Theoretical-practical assessment (with a minimum grade of 10), through 2 tests (35%) and 1 Research Work (15%).

Laboratory evaluation (with a minimum average grade of 10), through 13 Laboratory Assignments.

IMPORTANT: All assignments are mandatory and failure to meet delivery dates will result in a penalty of 5% of the grade for each day of delay.

Final Classification = Theoretical-practical (TP) (50%) + Laboratory (PL) (50%).

Students who obtain a Final Classification higher than 17 will be subject to an oral test to assess their knowledge. In case the student is not interested in defending his grade, he will be assigned a final classification of 17 values.
