Teaching methods
Teaching is done through registered lessons (42 hours, corresponding to 6 CFUs), including some lessons in streaming for questions. It is possible that this scenario will change according to the evolution of the pandemia.
The student is required to retrieve and understand the content transmitted during the frontal lessons, both through the study of the notes and through the consultation of textbooks.
The teacher is available for individual explanation during the classes, at the end of lessons or by appointment (by e-mail).
The teacher also uses supplementary teaching material (slide of lessons) loaded on the Elly platform.
On the Elly platform are also uploaded some examples of the multiple-choice questions of the written examinations.
Assessment methods and criteria
In order to achieve the final vote, the student must demonstrate that he has memorized and understood the fundamental concepts of each topic.
Assessment of learning involves the conduction of a written examination (1 hour) in remote mode through Elly and Teams platforms and consisting of 33 multiple-choice questions regarding all the program. To each correct answer is assigned a score of 1 point, zero points to the unanswered question and -0.25 points to the wrong answer. Each question has four possible answers and only one is the correct one.
The evaluation is expressed in thirtieths, with a minimum vote of 18/30 for the sufficiency. There is no way to improve the evaluation of the written examination with an oral examination.
At each exam session, after registration closes, the teacher will send all enrolled students a file with detailed instructions for the test, including the link for the connection on Teams and the link for uploading the identity document.
