	Teaching Methods
	BOTH COURSES CONSIST OF THEORETICAL LECTURES, DEVOTED TO THE EXPLANATION OF ALL THE COURSE CONTENTS AND CLASSROOM PRACTICES, PROVIDING THE STUDENTS WITH THE MAIN TOOLS NEEDED TO PROBLEM-SOLVING ACTIVITIES. LECTURES ARE IN ITALIAN.

	Verification of learning
	FOR EACH MODULE BOTH WRITTEN TESTS, AND ORAL INTERVIEWS WILL BE PLANNED. THE WRITTEN TESTS OF THE TWO MODULES WILL BE GENERALLY DONE IN THE SAME DAY. THE WRITTEN TESTS WILL CONSIST IN SOLVING TYPICAL PROBLEMS. THE SCORES WILL BE EXPRESSED ON A SCALE FROM 1 TO 30. TO PASS TO THE ORAL INTERVIEWS A MINIMUM SCORE OF 18 WILL BE ALWAYS NEEDED. THE WRITTEN TESTS WILL BE NOT PRESERVATIVE. THE WRITTEN TEST REFERRED TO THE MODULE OF RATIONAL MECHANICS IS MADE OF 2 EXERCISES: ONE REGARDING THE GEOMETRY OF MASSES (MAXIMUM THRESHOLD: 15 SCORES), AND THE OTHER ONE REGARDING THE ANALYTICAL MECHANICS (MAXIMUM THRESHOLD: 15 SCORES). THE STUDENT HAS 2 HOURS AND 30 MINUTES TO CARRY OUT THE WRITTEN TEST. THE SCORE IS EXPRESSED ON A SCALE FROM 0 TO 30 AND IT IS THE SUM OF THE SCORES OBTAINED IN EACH EXERCISES ABOVE. THOSE SCORES DEPEND ON THE STUDENT'S ABILITY IN APPLYING OWN KNOWLEDGE. TO PASS THE WRITTEN TEST A MINIMUM SCORE (BASED ON THE SINGLE SCORES ABOVE) OF 18 IS REQUIRED. THE WRITTEN TEST REFERRED TO THE MODULE OF STRUCTURAL MECHANICS IS MADE OF 2 EXERCISES (ONE ON THE SOLVING OF A PLANE SYSTEM OF BEAMS, ANOTHER ON THE SOLVING OF A CONTINUOUS BEAM). THE STUDENT HAS 3 HOURS TO WORK ON THE WRITTEN TEST. THE ORAL INTERVIEW OF EACH MODULE IS SUBJECTED TO BEING SELECTED IN THE CORRESPONDING WRITTEN TEST, AND AIMS AT EVALUATING THE KNOWLEDGE OF ALL TOPICS, AND COVERS DEFINITIONS, ARGUMENTS AND PROOFS. IN THE CASE OF THE MODULE OF RATIONAL MECHANICS, THE ORAL TEST CONSISTS IN 3 QUESTIONS RELATED TO THE ARGUMENTS WHICH HAVE BEEN TREATED DURING THE COURSE. A SCORE IN THE RANGE [0; 10] WILL BE ASSIGNED TO EACH ANSWER. THE ORAL TEST WILL BE PASSED ONLY IF THE TOTAL SCORE (I.E., THE ARITHMETIC SUM OF THOSE SCORES) IS LARGER THAN (OR EQUAL TO) 18. IN THE CASE OF THE MODULE OF STRUCTURAL MECHANICS, THE ORAL TEST, DEVELOPED THROUGH A WRITTEN TEST, AND COMPLETED WITH AN ORAL DISCUSSION AFTERWARDS, CONSISTS IN 6 QUESTIONS/EXCERCICE : I) 2 QUESTIONS ON THE CONTINUUM MECHANICS; II) 2 ON THE BEAM THEORY; III) 1 QUESTION STRESS STATE IN A BEAM; IV) 1 EXERCISE ON SAFETY VERIFICATION OF A BEAM. FOR EACH CORRECT ANSWER, THE STUDENT GETS 30 POINTS AS A MAXIMUM. A MINIMUM OF 18 POINTS IS REQUIRED FOR EACH ANSWER. THE FINAL MARK OF EACH MODULE IS, USUALLY, THE MEAN VALUE OF THE MARKS OF THE WRITTEN AND THE ORAL TESTS AND IT IS EXPRESSED ON A SCALE FROM 18 TO 30 (POSSIBLY WITH LAUDEM). ONCE MARKS HAVE BEEN OBTAINED IN THE TWO MODULES, THE OVERALL (I.E., FINAL) MARK WILL BE THE WEIGHTED ARITHMETIC MEAN OF THE AFOREMENTIONED TWO SINGLE MARKS. THE WEIGHTS ARE THE UNIVERSITY EDUCATIONAL CREDITS. LAUDEM WILL BE CONFERRED ONLY IN THE CASE OF AN EXCELLENT METHODOLOGIC ACCURACY.
