Description |
Guest lecture / keynote speech |
Lectures will be taught by a video-conference system in campus
classrooms of A Coruña, Santiago, Vigo and Madrid. The course teachers will explain
the contents of the course using slides and lecture notes. Students will be highly
encouraged to ask and question about any topic explained during the lectures. |
Multiple-choice questions |
Once the lecture period is over, a writing exam will be scheduled,
where the students will to solve questions and problems with the help of books
(included in the course bibliography) or their own lecture notes. In this test, the
students should show the knowledge accomplished on the course topics. |
Problem solving |
During this course, some exercises and problems related to the
course contents will be assigned. They will have to be solved and submitted taking
into account a prescribed deadline. |

Assessment comments |
For
those students which were using the second opportunity to pass their assessments, the deadline
for the submission of their assignments will be the final exam date
of this second opportunity. If the assignments would not be submitted
in this second period, only the assignments submitted in the period
of the first opportunity would be evaluated.
