Métodos de ensino e atividades de aprendizagem

The teaching methodology is based on theoretical-practical lectures and classroom practice. This methodology is complemented by the laboratory component that consists of carrying out laboratory work and a lab project.

Obtenção de frequência

The minimum grade in continuous assessment by tests is 8 points in any of the tests.
In situations where the teaching staff considers it necessary, final grades above 16 may have to be defended in an oral exam. If the student does not attend these oral tests, their final classification will be 16 points.

(In the evaluation by final exam or tests, questions related to the laboratory component of the UC are foreseen)
Once approved in continuous assessment, the student will only be able to improve their grade during the appeal period. Attendance and approval in the laboratory component (execution of all work, delivery of results and reports) is mandatory for approval in the UC.

Rules for carrying out tests:
• When requested, it is mandatory to present an identification document during the tests.
• Only written tests in EST Setúbal test/exam booklets are accepted.
• Leaving the room can only take place 30 minutes after the start of the test/exam and implies the final delivery of the test, and the delay in entry cannot, under any circumstances, exceed 15 minutes.
• Calculating machines with graphic or alphanumeric capabilities may only be used during the tests if the teacher authorizes it.
• During the tests, the handling or display of cell phones (which must be switched off) and other electronic equipment is not permitted, and the use of any of this type of equipment will result in cancellation of the test.

Fórmula de cálculo da classificação final

The final grade is calculated according to the following formula:
NF=0.8*EF+0.2*LAB;
EF- average classification of the 2 tests or the classification in the final exam;

LAB- laboratory classification (minimum 10 points).


In the case of assessment by exam, the grade for the EF component corresponds to the classification obtained in this test, and, as mentioned, attendance and approval in the laboratory component are mandatory to pass the UC.

Improvement of the distributed final classification
The student can improve their final grade obtained through continuous assessment by taking the second exam.
