Teaching methodology

The teacher explains the basic issues in the theory sessions, while opens discussions among and with the students on various topics. Each theory session includes the proposal of several issues related to the class, for students to work on them independently on their own.

The laboratory sessions follow an evolving line, based on the installation of the operating system and applications for users on it. The lab sessions are based on the well-defined lab book, and the teacher performs the necessary support to students, which functions similar to a senior manager training to novel and junior administrators.

Evaluation methodology

The autonomous learning competence is evaluated based on the reports delivered by the student during the course. Its weight is 10% on the final mark.

The technical competences are evaluated based on the theory (40%) and the laboratory exam (50%).

The theory gets evaluated based on the partial and the final exams. The mark of the 3 partial exams is computed as the averaged mean of the 3 tests, with the following weights: 25, 25, and 50%. If this mark is equal or larger than 5.0, attending the final exam is optional.

In case a student attends the final exam, his/her theory mark will be the highest between the mark obtained in the final exam and the averaged mean of the partial exams.
