The University of Santiago de Compostela contemplates 3 different scenarios in its document “directrices para o desenvolvemento dunha docencia presencial segura, curso 2020-21 (guidelines for the development of a safe face-to-face teaching, course 2020-21)”. It contemplates the use, for these scenarios, of the Virtual Campus (Moodle) that will use for the distribution of the educational materials, realization of test activities and communication of tasks, and the MS Teams to encourage the telematic communication with the students.
Scenario 1. Adapted normality.
Part I (master lectures and seminars): in the lectures, exposition lessons will be combined to present the theoretical contents, with the practical resolution of exercises that illustrate the theoretical contents. The seminars will focus on the performance of short evaluation tests, sometimes individual and others in groups, in order to evaluate the acquisition of the contents seen in the lectures. The active participation of students will be encouraged, both in lectures and in seminars.
Workshops: In the workshop 1 (basic wiring and automation for motor control), the students, divided into teams, will assemble various circuits that integrate various elements of power and control. At the end of the seminars the students will deliver a report of activities. In the workshop 2 carried out in the computer room, specific software will be used for the design of electrical installations (Simaris).
Tutorials: the two hours of group tutoring will be dedicated to the realization of a technical visit to the electrical installations of the ETSE and the subsequent exhibition, in groups of 2/3 people, of a brief study related to the visit.
The use of spreadsheets (Excel) and specific electrical installation design software (Simaris) will be encouraged to solve some of the problems in the bulletins.
Scenario 2. Distancing
Expositions lessons (master lectures) will be virtual by synchronous sessions, using the MS Teams application, and seminars, compulsory tutoring and workshops in the computer room and laboratories will continue to be carried out in person (ETSE installations). Moreover, the teaching methodology will be similar to that used in scenario 1.
Scenario 3. Lockdown
All the activities would be carried out virtually, synchronous telematics using Teams and asynchronous or synchronous telematics using Moodle. The teaching methodology used in Part I (activities, expository classes and seminars) would be similar to that used in Scenario 1, but tutoring would have to be replaced by a “virtual visit to ETSE electrical installations”. The laboratory work activities (workshop 1) should be replaced by presentations (video, slides). The computer room activities (workshop 2) would also be carried out using the Simaris program but should be delivered virtually in MS Teams.
The development of competences will be carried out through the different activities planned for the learning of the course.
CX.3 Exam. Lessons 1, 2, 3 and 4. Workshops 1 and 2.
CX.6 Exam. Lesson 5 and Workshops 1 and 2.
CX.11 Exam. Lesson 5 and Workshops 1 and 2.
CI.4. Exam. Lesson 1 to 4. Workshop 1.
CI.6. Lesson 5 and Workshops 1 and 2.
CT.6. Exam. Seminars of the subject.
CT.7. Exam. Tutorials and Workshops 1 and 2.
CT.11. Tutorials, technical visit and Workshop 2.
CT.13. Tutorials, Workshops 1 and 2
CT.19. Exam. Part I, classroom and Workshops 1 and 2.
The course has obligatory attendance for all the workshops, tutorials and seminars of the subject. The evaluation will be the result of a weighted average, in which the results obtained in the following items will be taken into account:
a. Exam: 50%.
b. Seminars and participation in the classroom: 20%.
c. Workshops: 20%.
d. Tutorials: 10%.
To pass the subject you must obtain a minimum score of 40% of the maximum score corresponding to each the examination, tutorials and workshops. The final examination, includes two parts, theory (30% of the overall score of the exam) and problems (70% of the overall score of the exam). In the theory part, the contents acquired in either the classroom or in the laboratories or in the tutorials will be evaluated.
Before the final exam, students will know the grades obtained in the continuous assessment (sections b, c and d). Those students who attended the workshops and tutorials, but did not obtained the minimum of 40% of the score corresponding to these activities, may be re-qualified again before the second opportunity exam.
The following table shows how it is the distribution of the activities:
Assessment distribution.............Scenario 1............Scenario 2.............Scenario 3
1.Continuous assessment (50%): Activities and participation+Tutorials+Workshops
Activities and participation (20%) In person............In person...............Telematic
Tutorial (10%).............................In person............In person................Telematic
Workshops (20%).......................In person…………..In person……….……..Telematic
2.Final exam (50%): theory and problems
Theory (15%).............................In person…………In pers/Telematic…..Telematic
Problems (35%)........................In person………..In pers/Telematic…...Telematic
If it is detected that any assignments or tests were carried out in a fraudulent manner by the students, the document "Regulations for assessment of the academic performance of the students and for revision of marks" ("Normativa de avaliación do rendemento académico dos estudiantes e de revisión das cualificacións") will be of application.
Assessment of competences:
CX.3 Exam. Lessons 1, 2, 3 and 4. Workshops 1 and 2.
CX.6 Exam. Lesson 5 and Workshops 1 and 2.
CX.11 Exam. Lesson 5 and Workshops 1 and 2.

Seminars: 6.0
Laboratories: 15.0
Individualized tutorials: 2.0
Review and revision: 5.0
Personal work at home, total: 92.0 h
Expository classes: 36.0
Seminars: 18.0
Laboratories: 18.0
Individualized tutorials: 4.0
Review and revision: 16.0
TOTAL HOURS: 150.0 (6 ECTS)
The in-class study indicates the number of hours that were planned for the various activities that will be carried out in the ETSE, theory classes, problems, workshops in the laboratory and in the computer room, tutorials, as well as the final examination. In personal work, the associated activities of the student outside the classroom were estimated. The total hours, 150 hours, are the sum of the hours of personal and in-class time and are adjusted to the corresponding 6 ECTS assigned to the subject.
It is recommended that students pass Mathematics and Physics courses. Class attendance is also recommended, as well as the use of the Virtual Campus of the subject (Moodle) in accordance with the indications indicated above.
In the case of remote teaching, it will be necessary to have a computer with microphone and camera for carrying out the different activities programmed along the semester. It is recommended to purchase equipment with the MS Windows system, as other platforms do not support some of the computer programs used in the subjects, available at USC.
Improve information and digital skills with the resources available at USC
The subject will be taught in Galician, although English information sources will be handled.
The admission of students registered in the laboratory of practices requires that these know and they fill the "general safety instructions in the laboratories of practices" of the University of Santiago de Compostela. This information is available at the web page: www.usc.es/estaticos/servizos/sprl/normalumlab.pdf. Moreover, a basic instruction manual will be provided to the students for each of the practices, which will include the most relevant aspects in relation to safety and prevention of occupational risks.
The facial mask must be used by the students at all times during their presence in the ETSE. All indications by the health authorities and the USC for health protection against COVID-19 must be followed rigorously. Use mask, apply handrub, or wash hands with water and soap according to the recommendations, and, whenever possible, increase the physical distance with colleagues and instructor in the classroom.
Contingency plan:
To adapt to the 3 scenarios, contemplated by the USC, the following adaptations will be made in the section of methodology and assessment:
METHODOLOGY
Whatever the scenario, the schedule of classes, practices and exams established by the ETSE will be scrupulously respected. The difference will be the use of telematic tools (MS Teams) for the master classes of stage 2 and for all types of activities with the student in stage 3. The teaching materials will be distributed via Virtual Campus (Moodle).
The main difference would be that in scenario 3 it would not be possible to carry out experimental practices in the laboratory of Part II of the subject and the technical visit scheduled in the tutorial, which would be replaced by presentations, videos and the realization of a work. The rest of the scheduled activities can be taught indifferently in person or online.
Voluntary (individual) tutorials, for questions, will preferably be done using MS Teams.
ASSESSMENT SYSTEM
The assessment system will be the same independently of the scenario in which the semester be developed (in-person or remote). Therefore, no changes to the evaluation system are contemplated. In any case, the activities that are assessed in person (seminars, tutorials or workshops) are replaced, as indicated by their telematic equivalents.
