It will be necessary to attend at least 80% of the face-to-face sessions to be evaluated through the aforementioned weightings. Students who take advantage of the blended modality will be able to follow the subject through the Virtual Course on the tele-teaching platform Moodle, of the University of Vigo, which will allow access to the necessary materials for the acquisition of the skills and achievement of the results of learning, both its theoretical and practical contents. The teaching methodologies and evaluation activities will be specified, along with the delivery schedule (in-person or remote) that will be clearly established. Activities that require presence will be replaced by others that allow access to the same percentage of the grade. Individualized monitoring of student participation through ICT will be done using the platform's own tools (participation, access statistics, online tests or exercises, etc...). The student must meet the minimum requirements for attendance, attending the tutorials, which will be set at a time compatible with their activity, to resolve any doubts that arise during the continuous evaluation. You must also attend the tests that the teacher(s) consider essential. Those students who choose to be evaluated through the "global evaluation" modality must notify the teaching staff responsible for the subject within 31 business days from the beginning of each semester (article 19.4  of the Regulamento sobre a avaliación, a calificación e a calidade da docencia e do proceso de aprendizaxe do estudantado of the Universidade de Vigo). Those students who cannot take part in the continuous evaluation will be evaluated on the contents of the subject program through a written test that will account for 70% of the final grade and a practical work (which represents the remaining 30%).
