| THE COURSE INCLUDES 96 HOURS OF IN PERSON LECTURES DELIVERED IN TWO DIDACTIC MODULES. MODULE 1 IS COMPOSED OF 32 HOURS DEDICATED TO THEORETICAL LECTURES AND 16 HOURS DEDICATED TO EXERCISES AND LABORATORY ACTIVITIES. MODULE 2 IS COMPOSED OF 24 HOURS DEDICATED TO THEORETICAL LECTURES AND 24 HOURS DEDICATED TO EXERCISES AND LABORATORY ACTIVITIES. |
| Verification of learning | |
|---|---|
| THE FINAL EXAM IS ACHIEVED THROUGH A PROJECT REPORT AND AN INTERVIEW. THE VERIFICATION WILL CONSIST IN THE DISCUSSION OF THE PROJECT APPLICATION DEVELOPED BY THE STUDENT, POSSIBLY IN A GROUP, DURING THE COURSE AND AIMED AT VERIFYING THE LEVEL OF KNOWLEDGE AND UNDERSTANDING ACHIEVED BY THE STUDENT, THE PRESENTATION ABILITY, THE ABILITY TO AUTONOMOUSLY ORGANIZE WORK AND THE ABILITY TO WORK IN TEAM. THE EXAM MAY BE DIVIDED INTO TWO PARTIAL TESTS, ONE OF WHICH AT THE END OF THE FIRST MODULE. FOR EACH TEACHING MODULE, THE CORRESPONDING VERIFICATION TEST INVOLVES THE DEVELOPMENT AND DISCUSSION OF A DESIGN APPLICATION, THROUGH A PRESENTATION (ABOUT 20 MINUTES) AND SUBSEQUENT DISCUSSION (10 MINUTES) OF THE SOLUTION TO THE ENGINEERING PROBLEM PROPOSED DURING THE EXERCISE AND LABORATORY HOURS. THE FINAL EVALUATION WILL BE THE ARITHMETIC MEAN OF THE MARK OBTAINED IN THE TWO PARTIAL TESTS. THE FINAL MARK IS BETWEEN 18 AND 30 CUM LAUDE. THE MINIMUM (18) IS ASSIGNED TO THE STUDENT SHOWING A WEAK ABILITY OF APPLYING METHODS AND A LIMITED KNOWLEDGE OF THE PROPERTIES OF THE SYSTEMS PRESENTED IN THE COURSE. THE MAXIMUM (30) IS GIVEN TO THE STUDENT SHOWING AN IN DEPTH KNOWLEDGE OF ALL THE TOPICS TREATED IN THE COURSE AND WHEN HE/SHE IS ABLE TO APPLY THIS KNOWLEDGE EFFECTIVELY AND ACCURATELY SUPPORTING THE CHOICES DONE. THE LAUDE IS GIVEN WHEN THE CANDIDATE SHOWS EXTRAORDINARY KNOWLEDGE OF THE TOPICS TREATED IN THE COURSE, FULL OF DETAILS, AND HE/SHE IS ABLE TO ELABORATE IDEAS AND PUT TOGETHER THE CONCEPTS IN CONTEXTS THAT ARE EVEN DIFFERENT FROM THOSE ONES DESCRIBED IN THE COURSE. |
