Métodos de ensino e atividades de aprendizagem

The lectures will serve to theoretical exposition of the course syllabus. The classes will have a component based on examples, in terms of applications of the contents taught in lectures, and on problem-solving and worksheets. In laboratory classes are scheduled 4 works. Approval of the theoretical and practical component is provided with the completion of course’s final written evaluation. The written evaluation has a weight of 60% in the final grade, and is constituted by 5 tests during the course or by a final exam. The lab evaluation has a weight of 20% of the final grade, with mandatory submission of reports. The minimum grade in any component of assessment is 9,5 points (on a scale 0-20). Final scores above 16 points will be defended in oral examination if considered necessary. To stimulate the spirit of learning, a work group is due with 20% weight in final grade.

Obtenção de frequência

The approval in the discipline can be obtained by continuous evaluation or by final examination.
Continuous assessment and final assessment includes a mandatory laboratory component and theoretical component.

The written component consists of:
1) Perform 5 continuous evaluation tests.
or
2) Take the final exam.

The laboratory component consists of:
1) Execution of the 4 lab assignments with delivery of the respective report by e-mail until the last laboratory class.
2) Execution of a lab project with delivery of the respective report and software (on a date according to the laboratory shift), with oral discussion in that same class.

The laboratory component is exempt from students who have attended it, with approval, in the immediately preceding academic year.

The final exam evaluation consists of the normal period exam. Anyone who does not have the approval in the theoretical component of the continuous or final evaluation can recover in the examination of the time of appeal. Anyone who has passed the theoretical component of the continuous assessment may improve the grade in the examination of the resource period. The minimum grade of the resource exam is 9,5 points.

All exams and interim tests are written, individual and without consultation.

If the teacher responsible for the discipline deems it necessary, final classifications of more than 16 values ​​will have to be defended in oral tests. If the student does not attend the oral test, his final grade will be 16 points.

Fórmula de cálculo da classificação final

The continuous assessment grade (N) is calculated according to the following formula:
N = 0,6*T + 0,2*L1 + 0,2*L2, with T, L1 and L2> = 9,5 values,

at where:

T: Mean of the scores of the 5 interim tests or grade of normal period exam;
L1: Note of the 4 laboratory works;
L2: Note from the lab project.

In continuous evaluation, attending the 5 tests is mandatory. A student can only have 2 tests with a score of less than 8,5 values. The average of the 5 tests must be greater than or equal to 9,5 values.

The minimum mark of all continuous evaluation components (T, T, L1 and L2) is 9,5 values.
