Métodos de ensino e atividades de aprendizagem

After the theoretical exposition of the subjects, they are illustrated through problem solving, in which students are encouraged to actively participate. In addition, students carry out a group project where they apply knowledge according to the syllabus. The delivery of the project is divided into several stages (with phased deliveries).

Obtenção de frequência

Performance of 2 Tests – TE
Performance of 1 Projetc - PR

Fórmula de cálculo da classificação final

Final grade = 0,7*TE + 0,3*PR


Project evaluation is divided into the following phases:

1st phase (delivery of the 1st part of the Project) - 5%
2nd phase (delivery of the 2nd part of the Project - 5%
3rd phase (delivery of the final part of the Project) - 15%
4th phase (oral presentation of the Project) - 5%

Observações

During exam periods, students can recover one of the Tests or recover both Tests;

The Projetc is done in groups;

Tests are performed with consultation;
