Frontal lessons, interaction by means of Moodle platform

Slides and supporting material available on Moodle platform

Written exam with multiple-choice and open-ended questions on the topics covered in the course. The maximum score achievable will be specified for each question. The total score is 31 points, which allows for an overall grade of 30/30 with honors. The minimum passing score for the written exam is 18 points. Students who pass the written exam may (optionally) attempt to improve their grade by taking an oral exam during the same exam session. However, a failure in the oral exam will invalidate the written exam grade (the oral exam takes precedence over the written exam). Knowledge of specific topics, fluency in language, and the ability to identify correlations between environmental issues will be assessed. Any changes to the procedures described here, which may be necessary to ensure the application of safety protocols related to possible emergency situations, will be communicated on the Department, Degree Program, and course websites.
