Teaching method

There are two hours of lectures and a lab session of three hours each week.

Lectures are problem-driven. They start with a concrete problem, which motivates the presentation of some computer systems topic, some data type or some programming language construct, and end with the complete source code of a program that solves it.

In the lab classes, students design, implement and test programs for solving simple problems in Science and Engineering fields.

Evaluation method

Please see the portuguese version. If there are Erasmus students this part will be filled.
