THE MINIMUM PERCENTAGE OF ATTENDANCE REQUIRED IS 70% FOR EACH OF THE ACTIVITIES. THE COURSE IS ORGANIZED AS FOLLOWS: - CLASSROOM LECTURES ON ALL THE TOPICS OF THE COURSE; - DEVELOPMENT OF THE DESIGN EXERCISES: - DRAFTING OF AN ANNUAL PROJECT AIMED AT THE PRELIMINARY DESIGN OF A FIRE-FIGHTING SYSTEM BASED ON HYDRANTS - DRAFTING OF A YEAR PROJECT AIMED AT THE PRELIMINARY DESIGN OF THE DISPOSAL OF RAINWATER FROM BUILDINGS. . MODALITY: STUDENTS WILL BE DIVIDED INTO GROUPS (4 TO 6 STUDENTS PER GROUP) AND WILL FOLLOW 12 GUIDED EXERCISES OF 5 HOURS EACH. AT THE END OF THE GUIDED EXERCISES, STUDENTS WILL HAVE TO CARRY OUT THE ANNUAL PROJECTS, WHICH WILL BE INDIVIDUALLY VERIFIED AT THE MOMENT OF THE ORAL EXAM. |
| Verification of learning | |
|---|---|
| THE ACHIEVEMENT OF THE LEARNING OUTCOMES IS CERTIFIED BY PASSING AN EXAM WITH EVALUATION IN THIRTIETHS (SCALE 0-30), THE MINIMUM GRADE IS 18/30 (BASIC KNOWLEDGE OF THEORETICAL FUNDAMENTALS, CALCULATION METHODOLOGIES AND SUFFICIENT COMPETENCE ON THE DEVELOPED PROJECTS) AND THE MAXIMUM GRADE IS 30/30. THE MAXIMUM MARK CAN BE ADDED "CUM LAUDE" (30 CUM LAUDE). THE EXAM INCLUDES A WRITTEN TEST AND AN ORAL TEST THAT MAY TAKE PLACE ON DIFFERENT DAYS, PREVIOUSLY SCHEDULED. THE WRITTEN TEST IS PRELIMINARY TO THE ORAL EXAMINATION. THE ORAL EXAM INCLUDES THE PRESENTATION OF THE PROJECTS, AND ON TOPICS INDICATED BY THE TEACHER. THE WRITTEN TEST CONSISTS IN ANSWERING THEORETICAL QUESTIONS AND IN SOLVING NUMERICAL PROBLEMS. THE TEST HAS A DURATION OF NO MORE THAN 120 MINUTES AND IS AIMED AT VERIFYING THE ABILITY TO CORRECTLY APPLY THE THEORETICAL KNOWLEDGE, THE ABILITY TO UNDERSTAND THE PROPOSED PROBLEMS AND THE ABILITY TO COMMUNICATE IN A WRITTEN MANNER. IF IN THE PRESENCE, DURING THE TEST IT IS NOT ALLOWED TO CONSULT TEXTS OR TO USE A PC OR SMARTPHONE; A POCKET CALCULATOR IS ALLOWED. THE TEST TAKES PLACE BEFORE THE ORAL EXAM AND IS CONSIDERED TO HAVE BEEN PASSED WITH THE ACHIEVEMENT OF A PRE-ESTABLISHED MINIMUM SCORE. THE ORAL EXAM CONSISTS OF A DISCUSSION LASTING ABOUT 30 MINUTES AIMED AT ASCERTAINING THE LEVEL OF KNOWLEDGE AND UNDERSTANDING ACHIEVED BY THE STUDENT ON THE THEORETICAL AND METHODOLOGICAL CONTENTS INDICATED IN THE SYLLABUS. THE ORAL TEST WILL ALSO ALLOW THE STUDENT'S COMMUNICATION SKILLS TO BE VERIFIED WITH THE LANGUAGE AND AUTONOMOUS ORGANIZATION OF THE EXPOSITION. THE ORAL EXAM INCLUDES A DISCUSSION OF TECHNICAL WORKS PRODUCED BY THE STUDENT INDEPENDENTLY OR IN A GROUP ON A CASE STUDY PROPOSED BY THE TEACHER AS A LABORATORY ACTIVITY. THE DISCUSSION WILL ILLUSTRATE THE PROBLEMS POSED BY THE ASSIGNED CASE, THE POSSIBLE PROJECT ALTERNATIVES, THE POSSIBLE REGULATORY CONTEXT, THE METHODOLOGICAL APPROACH ADOPTED, THE ANALYSIS OF THE RESULTS OBTAINED. DURING THE DISCUSSION SLIDES CAN BE USED AND PROVIDE FOR THE REQUEST FOR THEORETICAL INSIGHTS AND DETAILED CLARIFICATIONS BY THE MEMBERS OF THE EXAMINATION COMMITTEE. THE EVALUATION OF THE ORAL TEST WILL BE CARRIED OUT ON THE BASIS OF THE FOLLOWING INDICATORS: COMPLETENESS, PRESENTATION, RELEVANCE. THE TEST AS A WHOLE MAKES IT POSSIBLE TO ASCERTAIN BOTH THE CAPACITY FOR KNOWLEDGE AND UNDERSTANDING, AND THE ABILITY TO APPLY THE SKILLS ACQUIRED, BOTH THE ABILITY TO EXHIBIT, AND THE ABILITY TO LEARN AND DEVELOP SOLUTIONS IN INDEPENDENT JUDGMENT. THE FINAL GRADE USUALLY COMES FROM THE AVERAGE OF THE TWO TESTS. THE HONOURS CAN BE AWARDED TO STUDENTS WHO REACH THE MAXIMUM SCORE OF 30/30 AND DEMONSTRATE TO BE ABLE TO INDEPENDENTLY APPLY KNOWLEDGE AND SKILLS ACQUIRED EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED IN CLASS. |
