Métodos de ensino e atividades de aprendizagem

The teaching method is based on:

- Theoretical-practical classes in which the different contents are presented followed by a participatory method of the students through practical problem.
- Practical-laboratory classes in which students will carry out tests with real-scale equipment in order to deepen their knowledge about heating equipment and in another phase the students will develop group work of sizing and energy analysis of heating systems.

Obtenção de frequência

To obtain classification in the laboratory, the presence and preparation of test reports and laboratory work is mandatory.
In order to be considered in the evaluation, the reports must all be delivered on time and individually approved with a minimum score of 10 points. An overall score will be given to the reports.
The minimum test grade is 8.5 values.
Oral assessment can be performed:
- in the laboratory component
- in tests rated higher than 16 points

Fórmula de cálculo da classificação final

The calculation of the classification will be made based on work reports and tests or exam according to the following rules:
Final Grade = 0.75 (Score from test 1 + test 2)/2 + 0.25 (Reports grade)
Final Grade = 0.75 (Score from exam) + 0.25 (Reports grade)
