	Teaching Methods
	THE COURSE IS STRUCTURED INTO THEORETICAL LECTURES AND EXERCISES BOTH IN THE CLASSROOM AND LABORATORY. PRACTICAL PROBLEMS WILL BE PROPOSED IN THE FIELD OF THE ANALYSIS OF THE DURABILITY OF MATERIALS. LABORATORY EXPERIENCES WILL STRENGTHEN THE CONCEPTS ACQUIRED. LECTURES ARE PROVIDED IN CLASSES IN THE PRESENCE OF STUDENTS. IN PARTICULAR, THE COURSE IS STRUCTURED IN 45 HOURS OF THEORY, 15 HOURS OF EXERCISES/LAB ACTIVITIES. ATTENDANCE IS 70% MANDATORY AND WILL BE MADE KNOWN ELECTRONICALLY OR BY THE TEACHER. ACHIEVEMENT OF THE REQUIRED PERCENTAGE OF ATTENDANCE WILL BE VERIFIED BY ACTUAL PARTICIPATION IN WORKSHOP ACTIVITIES.

	Verification of learning
	THE ASSESSMENT OF THE PREPARATION WILL BE PERFOMED AT THE END OF THE COURSE BY AN ORAL INTERVIEW WHICH IS INTENDED TO CHECK THE LEVEL OF LEARNING AND THE DEGREE OF COMPREHENSION OF THE ARGUMENTS. THE ASSESSMENT IS BASED ON THE LEVEL OF KNOWLEDGE ACQUIRED, ON THE CORRECTNESS OF EXPRESSION AND TERMINOLOGY, AND THE ABILITY TO CONNECTING CONCEPTS. IN ORDER TO PASS THE EXAM, STUDENTS MUST AT LEAST BE ABLE TO IDENTIFY THE CAUSES OF DETERIORATION OF BUILDING MATERIALS AND POSSIBLE PREVENTION AND RECOVERY STRATEGIES. THE LEVEL OF EXCELLENCE CAN BE REACHED BY STUDENTS WHO SHOW TO BE ABLE TO ADDRESS NON-STANDARD PROBLEMS OR NOT SPECIFICALLY PRESENTED DURING THE LECTURES, WITH PARTICULAR REGARD TO THE CORRECT APPLICATION OF THE CORRELATIONS BETWEEN STRUCTURE, CONSTRUCTION AND DURABILITY.
