| KNOWLEDGE AND UNDERSTANDING: TO KNOW THE MAIN IDEA AT THE BASIS OF PHYSICAL PHENOMENA; TO UNDERSTAND THE TERMINOLOGY. ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING TO BE ABLE TO IDENTIFY THE PHYSICAL MODELS THAT CAN BE TREATED BY THE THEORETICAL KNOWLEDGE ACQUIRED. MAKING JUDGEMENT TO BE ABLE TO CHOOSE THE APPROPRIATE METHODOLOGIES TO ANALYZE THE PROBLEMS UNDER STUDY. TO EVALUATE THE SOLVING PROCEDURES BY MEANS OF SUITABLE MATHEMATICAL TECHNIQUES. COMMUNICATION SKILLS TO BE ABLE TO SHOW, IN WRITTEN AND ORAL FORM, THE CONCEPTS AND THE SOLVING METHODS OF THE PHYSICAL PROBLEMS UNDER STUDY. LEARNING SKILLS TO BE ABLE TO APPLY THE KNOWLEDGE OBTAINED DURING THE CLASS, TO ANY CONTEXT, EVEN APPARENTLY DIFFERENT FROM THE STANDARD ONES. TO DEEPLY EXAMINE THE PROGRAM TOPICS, BY USING DIFFERENT AND COMPLEMENTARY APPROACHES. |

| Teaching Methods | |
|---|---|
| THE COURSE IS ORGANIZED IN LECTURES EXPLAINING THE FUNDAMENTAL CONCEPTS OF MECHANICS. EACH LECTURE IS DEVOTED TO THE THEORETICAL INTRODUCTION OF ONE OR MORE TOPICS FOLLOWED BY EXAMPLES AND APPLICATIONS. |
| Verification of learning | |
|---|---|
| THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN EXAM. EXAMINATION IS GRADED ACCORDING TO A SCALE RANGING FROM 0 TO 30, WITH 18 AS A PASS MARK. THE EXAM INCLUDES A WRITTEN TEST (WHICH MAY BE DIVIDED INTO TWO IN ITINERE TESTS) AND AN ORAL EXAM THAT TAKE PLACE ON DIFFERENT DAYS, ACCORDING TO A PRE-ESTABLISHED CALENDAR. ACCESS TO THE ORAL EXAM IS ALLOWED TO STUDENTS WHO HAVE PASSED THE WRITTEN TEST (PASS MARK: 15/30). IN THE WRITTEN TEST THE STUDENT MUST DEMONSTRATE TO KNOW THE FUNDAMENTALS OF CLASSICAL MECHANICS, DISCUSSING AND SOLVING TWO OR THREE PROBLEMS. THE TEST HAS A DURATION OF TWO HOURS. THE ORAL EXAM IS AIMING AT EVALUATING THE STUDENT'S ABILITY TO CRITICALLY DISCUSS SIMPLE SITUATIONS RELATED TO MECHANICS. THE ABILITY TO FORMULATE MODELS AND DISCUSS THEIR IMPLICATIONS IN THE LIGHT OF THE CONCEPTUAL FRAMEWORK PRESENTED DURING THE COURSE IS EVALUATED DURING THE ORAL EXAM. THE FINAL GRADE IS OBTAINED FROM THE AVERAGE PERFORMANCE IN THE WRITTEN TEST AND THE ORAL EXAM. THE MINIMUM MARK FOR PASSING THE EXAM IS 18/30. THE “LODE” (MAXIMUM GRADE WITH DISTINCTION) CAN BE GIVEN TO STUDENTS WHO OBTAIN A GRADE OF 30/30 AND SHOW THAT THEY ARE ABLE TO AUTONOMOUSLY USE KNOWLEDGE AND SKILLS IN CONTEXTS WHICH ARE NEW OR NOT DISCUSSED DURING THE COURSE. THE EXAMS CAN BE TAKEN IN THE FOLLOWING WAYS: (A) WRITTEN TESTS DURING THE COURSE (IN ITINERE WRITTEN TESTS) AND FINAL ORAL EXAM. STUDENTS ARE ADMITTED TO THE ORAL EXAM WITH A MINIMUM GRADE OF 15/30 ON EACH "IN ITINERE" WRITTEN TEST. (B) PERIODIC WRITTEN TESTS WITH ORAL EXAM ACCORDING TO THE CALENDAR SET BY THE TEACHING COUNCIL (CONSIGLIO DIDATTICO) FOR THOSE WHO HAVE NOT TAKEN OR PASSED THE IN ITINERE WRITTEN TESTS. CANDIDATES WHO HAVE OBTAINED THE PASS MARK OF 15/30 ARE ADMITTED TO THE ORAL EXAM. |
