Teaching method

During theoretical classes the teacher introduces the main concepts supported in adequate audio-visual means such as slides and videos which are facilitated afterwards to enhance autonomous study.


Experimental classes are synchronized with the theoretical ones. Students develop experimental work in the lab targeting also team work.

Evaluation method

Option 1: Continuous Evaluation

- 1st Test (T1) in person, if the pandemic situation allows it;

- 2nd Test (T2) in person, if the pandemic situation allows it;

- Practical work 1 (TP1) about welding;

- Practical work 2 (TP2) about metal casting.

 

Final grade = 0.70 x [(T1 + T2)/2] + 0.30 x [(TP1 + TP2)/2] 

with [(T1 + T2)/2] >= 9.0 values  and  [(TP1 + TP2)/2] >= 9.5 values.

 

To obtain frequency, the student must have at least 9.5 values in average in the Practical works. Students with frequency in the previous academic year (2021/2022) are automatically admitted to evaluation this year.

The student will be approved if the Final grade is equal to or greater than 9.5 values while have frequency to the discipline.

If the student has a Final grade equal to or higher than 18 values, an oral exam will be held to defend the grade.

 

Option 2: Final Exam  

All students with frequency to the discipline have access to the final exam.

The exam will be in person, should the pandemic situation allows it.

The final grade will be:

Final grade = 0.70 x Exam + 0.30 x [(TP1 + TP2)/2]

with Exam > = 9.0 values  and  [(TP1 + TP2)/2] >= 9.5 values.

The student will be approved if the Final grade is equal to or greater than 9.5 values while have frequency to the discipline.

If the student has a Final grade equal to or higher than 18 values, an oral exam will be held to defend the grade.

 

If the student fails, the grade of the practical works will remain valid for 1 academic year.
