ONGOING EVALUATION During the first and second semester, ongoing activities will be proposed such as: homework, group activities in the classroom, Problem Based Learning type activities. The activities evaluated during the course have several objectives, including: helping students to gradually understand what teachers' requests are (training objectives and expected learning outcomes); encouraging a constant study commitment during the entire duration of the course; favoring an overall assessment that is less subject to emotional factors or elements of chance; developing soft-skills such as functional literacy competence, personal competence, social competence, the ability to learn to learn. FINAL WRITTEN TESTS (PARTIAL AND COMPLETE) Complete written exam (open to all students) The complete written test consists of four exercises (2 for each part of the course). The time available to carry out the test is 4 hours. The written exam is passed if the complete test is assessed with a score of at least 18/32. Partial written tests (reserved for students enrolled in the 2nd year of the current academic year) There will be two partial written tests. The first partial test consists of two exercises on the first part of the course (mechanics) and can be taken in the winter exam session between the first and second semester (January and/or February). The second partial test, which will be concomitant to the complete tests in June and July, consists of two exercises on the second part of the course (thermodynamics and fluids). The time available to carry out each partial test is 2 hours. If the first partial test (mechanics) is passed with a mark of at least 15/32, the student is also entitled to take the partial test relating to the part of thermodynamics and fluids. If the second partial test is passed with a score of at least 15/32 and such that the arithmetic mean of the two tests is larger than or equal to 18/32, the overall written test has been passed. ORAL EXAM During the oral exam, the teacher verifies that the student has understood the contents of the course and he/she is able to present them in a clear way. More in detail, the teacher can ask for: - the solution of an exercise - the analysis of a real situation that can be described using the models presented in the course - the description of a model and of its limits of validity - the demonstration of a physical relation The duration of the oral exam is at the discretion of the professors. ACCESS TO EVALUATED TESTS AND FINAL SCORE To be able to take the oral exam, it is necessary to have obtained an access score > = 18. The access score can result from either a combination of the ongoing assessment and the final written test, or from the final written test only: A. (reserved for students enrolled in the 2nd year in the current academic year) The access score results from a combination of the ongoing assessments and the written test, according to an algorithm that will be described at the beginning of the course by the teachers and reported in detail on the Aulaweb page of the course. In order for the ongoing assessments to contribute to the access score to the oral exam, it is necessary to take part in a large fraction of them, that will be better quantified before the beginning of the course.. In order for the written test (1 complete, or 2 partial tests as described above) score to be valid as an access score, it must be > = 18. B. (possible for all students) The access score results from the written test only (1 complete or two partial tests). An access score that is >= 18/32, obtained in mode A or B, remains valid for the entire academic year. For example, in the academic year 2022/23, the achievement of an access score > = 18/32 starting from the session of June 2023 gives the right to take the oral test in any following session, up to and including that of February 2024. EXAM CALENDAR The dates of the written tests are reported on Aulaweb and on the exam calendar on the University website. Registration for the written tests through the Unige website is mandatory, students are recommended to check the deadline for registration. The oral interviews take place during each exam session, in the days following the date of the written test. The teachers communicate the date, time and place of the oral interviews at the same time or immediately after the written test.
