Teaching Methods
THE COURSE IS ARTICULATED IN 72 HOURS (9 CFU) OF FRONTAL LECTURES (THEORY AND PRACTICE), TAKING PLACE IN THE CLASSROOM ALSO USING MULTIMEDIA FACILITIES. THE PRACTICAL ACTIVITIES ARE AIMED AT THE STUDENTS’ ACQUISITION, WITH “HANDS-ON” MODE, OF THE BASIC LAWS APPREHENDED DURING THE COURSES, THROUGH THEIR APPLICATION TO SIMPLE ALMOST REALISTIC PHYSICAL CASES
IN ORDER TO BE ELIGIBLE FOR THE FINAL EVALUATION PROCEDURE AND THE GAIN OF THE COURSE CREDITS, STUDENTS ARE REQUIRED TO HAVE ATTENDED THE COURSE FOR THE 70% AT LEAST OF THE SCHEDULED HOURS OF THE FRONTAL LECTURES.
Verification of learning
STUDENTS’ PROFIT IS ASSESSED THROUGH A MID-TERM TEST, A WRITTEN FINAL TEST AND AN ORAL INTERVIEW.
THE MIDTERM TEST, WHOSE DURATION IS 1.5 HOURS CONSISTS IN SOLVING EXERCISES/PROBLEMS CONCERNING THE TOPICS RELATING TO THE FIRST HALF OF THE COURSE.
THE FINAL WRITTEN TEST, WHOSE DURATION IS 1.5 HOURS, CONSISTS IN SOLVING EXERCISES/PROBLEMS CONCERNING THE TOPICS RELATING TO THE SECOND HALF OF THE COURSE.
EACH WRITTEN TEST CONSISTS IN SOLVING EXERCISES/PROBLEMS SIMILAR TO THOSE ONES AFFORDED DURING THE PRACTICAL ACITIVITIES PERFORMED IN THE COURSE.
THE STUDENTS NOT ATTENDING OR NOT SUCCEEDING THE MIDTERM TEST HAVE TO ATTEND A WRITTEN TEST, WHOSE DURATION IS 2,5 HOURS, WHICH WILL CONTAIN EXERCISES/PROBLEMS ON THE WHOLE COURSE TOPICS AND WILL TAKE PLACE AT THE SAME DATE AND TIME OF THE FINAL WRITTEN TEST.
THE WRITTEN TESTS ARE EVALUATED IN THIRTIES. THE FINAL SCORE IS OBTAINED TAKING INTO ACCOUNT OF THE OUTCOME OF THE ORAL INTERVIEW AND THE WRITTEN TESTS, WHICH HAVE A PREVALENT WEIGHT ON THE ASSESSMENT OF THE FINAL SCORE.
THE STUDENTS THAT WILL SHOW AN EXCELLENT KNOWLEDGE OF THE COURSE TOPICS, EXCELLENT ABILITY TO EXPOSURE THE ARGUMENTS BESIDES THE ABILITY TO APPLY THE ACQUIRED KNOWLEDGE TO THE SOLUTIONS OF PROBLEMS NEVER AFFORDED PREVIOUSLY DURING THE COURSE WILL BE AWARDED WITH THE SCORE OF MAGNA CUM LAUDE.
