The main teaching method consists of frontal lectures, accompanied by exercises (group work for attending students and individual work for non-attending students). The didactic material consists mainly of the slides discussed during the lectures, available in the online platform Elly. Attendance to the lessons is strongly recommended, as well as the participation to the group works. It is important to highlight the role of Elly as a communication platform between the lecturer and the students. The material used for the lectures will be upload in the platform and will serve for the preparation of the written exam.
Teaching will be carried out through classroom lectures with the aid of slides that will represent educational material available online at Elly platform in pdf format for students.
Assessment methods and criteria
The additive assessment of the learning is carried out through:
1. Exercises on a transversal nutrition topic. Exercises for attending students will consist of a group work related to the presentation of a nutrition case study set with the teacher. Exercises for non-attending students will consist of an individual work related to a nutrition case study set with the teacher. The test is evaluated with a scale of 0-5 points.
2. A written test with 36 close questions (multiple response) and 3 open questions. The duration of the exam is 1 hour and a half. Question topics are related to the theoretical and applicative contents discussed during the course, including the exercises. Maximum question mark for close questions is 0.5 points, with penalty for wrong answers (2 wrong answers subtract 0.5 points). Maximum question mark for open questions is 3 points. The ability to synthesize and link the topics will be particularly rewarded. Maximum mark for the written test is 27, while the minimum to pass the exam is 18 points. Please note that the online registration for the exam is compulsory.
The final grade is obtained from the sum of the marks of both tests (in thirtieths). Honors (lode) are granted when reaching the maximum mark and demonstrating a deep knowledge of the topic vocabulary.
The summative assessment of the learning is carried out through:
1. a semi-structured written test with three open questions during the course, not compulsory, which deals with the topics: metabolic regulation and non-nutritive food components. During the written exam, the student is asked to answer the questions in a concise manner. The duration of the exam is 1 hour and a half, the weight of the questions is fairly divided, the evaluation scale is from 0 to 30, and the final mark is obtained by averaging the evaluation of each question. The ability to synthesize and link the topics will be particularly rewarded.
2. a group work consisting in the presentation of a nutrition case study set with the teacher. The test is evaluated with a scale of 0-30.
3. an oral exam which will focus on the last two parts of the program (particular nutrition and food information to consumers) with an indicative half-hour duration. The oral exam is evaluated with a scale of 0-30.
The final grade, communicated at the end of the oral exam, is obtained from the arithmetic average of the marks of the 3 tests (in thirtieths) or of the 2 tests if the student decides not to take the test during the course.
The mark of the written test during the course is communicated within the two weeks following the test, by publication on Elly platform. Please note that the online registration for the exam is COMPULSORY both in the case of the written test and the oral exam.
