Three scenarios are foreseen in the USC guidelines for the 2020-2021 academic year, depending on the COVID-19 pandemic situation. This course will have a Virtual Classroom with basic resources and serving as primary channel in any of the scenarios.
SCENARIO 1: adapted normality (no major restrictions on population mobility)
- Lectures and interactive lectures will be basically carried out in a face-to-face basis, although remote learning (e.g. through videos) could be employed up to a maximum of a 10% of the lecturing hours and 25% in the case of practical sessions.
SCENARIO 2: social distancing (partial restrictions on population mobility)
- Lectures will be performed remotely in a synchronous or asynchronous way, maintaining the timetable established for face-to-face lectures in the fist case, by using the Virtual Classroom and/ior MS Teams, or will be combined 50% with the face-to-face way, in teaching spaces where distance is possible. Seminars and tutorials will be hold face-to-face, or combined at 50% in teaching spaces where distance is possible. Practical sessions may combine remote learning (up to a 50%) and lab sessions, if social distancing is required. Practical sessions will include the completion of a test and a report, before and after each session, respectively.
SCENARIO 3:
- Lectures will be performed remotely in a synchronous or asynchronous way, maintaining the timetable established for face-to-face lectures in the fist case, by using the Virtual Classroom and/ior MS Teams. Seminars and tutorials will be hold remotely in synchronous way through MS Teams. Practical sessions will be performed entirely by remote learning making use of different resources available on the web (e.g, videos) and experimental data that will be provided to student through the Virtual Classroom and/or MS Teams. Practical sessions will include the completion of a test and a report, to be completed through the Virtual Classroom.
Students’ grading will consist of a combination of continuous assessment and a final exam.
However, the grade of the student will be the maximum value for that either obtained in the final exam, or than that obtained by weighting the final exam grade with the continuous assessment, this last ranging between 25-40% of the overall value. Attendance to the interactive small group classes (seminars), very small group classes (tutorials), as well as laboratory practices, is mandatory. In addition student need must pass laboratory practical assessment in order to pass the course. Attendance to lab is also mandatory, in order to pass this course.
The grade obtained by the student in the course will consist of two parts:
1. A continuous assessment (40%) that will include:
- Exercises and tests carried out in the seminars (Sem): 20%
- Work during the tutorials (Tut):5%
- Lab sessions (Lab): 15%. In this case, tests, the report and work carried out on the lab sessions will be used for assessment.
Continuous assessment will be carried out from the beginning of the course, though different assignments and tests that will be indicated in the Virtual Classroom. Exercises will be assigned and collected randomly in seminar sessions and tutorials may include some assignments.
2. Final examination (FE) (60%)
The final examination will cover the whole contents of the course, thus, it will include issues related to laboratory sessions (representing 15%).
Depending on the Scenarions, this exam will be performed:
- Physically at the USC (scenario 1)
- Remotely (scenarios 2 and 3) by using the Virtual Classroom and/or MS Teams.
The grade of the student will not be lower to that obtained in the final examination neither to that obtained after considering continuous evaluation, as follows:
Final grade = maximum (0.4 x N1+ 0.6 x N2, N2)
Where: N1= numerical markcorresponding to the continuous evaluation (scale 0-10). N2= numerical mark corresponding to the final examination (scale 0-10).
For consideration of the continuous assessment in the final mark, a minimum mark of 4 in the final exam (N2) must be obtained.
Students repeating the course will have the same consideration than other students as regards attendance to lectures, with the exception of lab sessions. If a repeating student has passed the lab sessions in former years, (s)he will be exempted to perform lab experiments again and will retain their lab-related grading for a maximum of two academic years. Hence, they do not need to repeat lab sessions but will need to attend the remaining interactive lectures (seminars and tutorials).
However, students can always repeat lab sessions if they want, even if they have passed that part in previous years. In this case, they just need to communicate that to the lecturer.
In case of fraud or unethical behavior during the completion of tests, exams or assignments, the USC regulation as regards academic performance and grading (“Normativa de avaliación do rendemento académico dos estudantes e de revisión das cualificacións”) will be considered.

Risk management plan as regards COVID-19:
Depending on the evolution of to the COVID-19 situation, the USC may require changes in this program. Any change in the methodology and/or assessment system foreseen for scenarios 2 and 3 will be informed to students through the Virtual Classroom and other communication channels available.
