Método de ensino

The curricular unit is based on mix of theoretical lectures and practical classes. Each session will introduce new concepts and methodologies, as well as the applications of the learnt concepts using different computational tools. Different learning strategies will be used, such as lectures, slide show demonstrations, step-by-step tutorials on how to approach practical examples, questions, and answers.

The practical component is focused in exploring the different computational tools by the students, including a discussion on the best approach under different scenarios.

Método de avaliação

Exame final (100%) em ambas as épocas.
