Métodos de ensino e atividades de aprendizagem

The classes are theoretical-practical in nature, aimed at operationalising the concepts. The participatory and interactive lecture method is adopted. The aim is to lead students to draw conclusions, guiding them in this process so that they acquire the necessary knowledge and develop a critical spirit.

The course has a laboratory component, with the aim of illustrating some of the theoretical concepts taught in practice. In the laboratory classes, the students carry out experimental work according to the protocols provided, making the respective records and processing the results/answering questionnaires in class on a Worksheet.

The course has a laboratory component which, in accordance with the course's objectives:

- the operationalisation of the concepts taught;

- developing the ability to solve cases;

- the development of a scientific and experimental spirit;

- learning laboratory procedures and techniques and acquiring "knowing how to do" and "knowing how to think" skills;

- developing teamwork skills.

Obtenção de frequência

Students can choose between a continuous assessment regime or a final exam, although it is compulsory to fulfil the requirements imposed for the laboratory practice component.

1. Assessment by exam: the student will take the exam in the normal period and/or in the appeal period, and will pass if they have a final classification of at least 9.5.

Students with Student Worker status who opt for the examination system but who miss more than one piece of laboratory work must take a specific group specifically related to the laboratory component of the course in the final examination.
In the laboratory component of the exam, a minimum classification of 9.5 marks is required for approval.
The final mark in the subject, under the examination system, is the mark corresponding to the examination (the mark for the laboratory component does not count in its calculation).
2. Continuous assessment: the student will take 2 written tests throughout the semester.
1st Test: 04/12/2023 (at TP class time)
2nd Test: 18/01/2024 (15 h)
To pass, you must have a classification equal to or greater than 8.0 in each test.

For the purposes of passing the course, the minimum arithmetic average score for the tests is 9.5.

If the student obtains a classification equal to or greater than 8.0 in the 1st Test and less than 8.0 in the 2nd Test, they may choose to retake the 2nd Test on the normal exam date (in this case, they choose not to take the exam).
The student must attend at least 75 % of TP classes (in this case, this corresponds to a maximum of four absences).
Without attending the laboratory classes and handing in the respective Worksheets (duly prepared), the student will not pass the UC, whether they are in the continuous assessment regime or the examination regime. A maximum of one absence from a laboratory class is permitted. Working-student students are allowed to take a test for the laboratory component on the exam date if they have missed more than one laboratory assignment.

Fórmula de cálculo da classificação final

Assessment by Exam:
Final classification = Exam Classification
(rounded to the nearest integer)

Assessment by Tests:
Final classification=0.50x1st Test Classification+ 0.50x2nd Test Classification
(tests quoted to the nearest tenth; final mark rounded to the nearest integer)
