Teaching method


The classes try to give students a solid theoretical formation complemented with practical experience on some of the subjects. The two hours of weekly lecturing classes include an average of one and a half theory exposition hours and thirty practical minutes, composed by resolution of exercises and demonstrations of the use of the learned systems (e.g. DNS and Apache configuration). In the two laboratory weekly hours the students learn about two development environments and implement two projects where the work deeply on two subjects: the web technology and the use of multimedia distributed applications in telecommunication networks.


Evaluation method

The final grade has a theoretical component and a practical component, weighting respectively 50% and 50%. Students are approved if they have a minimum grade of 9 for each component and a total grade of 10. Theoretical assessment approval can be accomplished through a final exam, or 80% in the final exam and 20% in an videoconference oral discussion (without minimal grade) - the best grade is considered. Practical assessment approval can be accomplished by implementing two laboratory works. The assessment of the laboratory projects is accomplished in group discussions with individual grades, covering the theoretical and practical aspects of the project.
