Teaching method
Lectures consist of a theoretical exposition, illustrated by application examples, and supported by slides and the usage of the software development environment of the lecturer.
In the lab sessions, students solve problems by concretely applying the concepts discussed in the previous lectures.
Students may clarify any doubts during classes or in the instructor’s contact hours.
Evaluation method
The evaluation includes 2 tests (corresponding to a total of 45% of the final grade) and 2 projects (55% of the final grade). One of the projects, and corresponding test, focuses primarily in quality models, verification and validation. The other project, and corresponding test, focuses on reverse engineering, reengineering and the application of design patterns.
