Verification of learning
THE ACHIEVEMENT OF THE LEARNING OUTCOMES IS CERTIFIED BY PASSING AN EXAM WITH EVALUATION IN THE THIRTIETHS (SCALE 0-30); THE MINIMUM GRADE IS 18/30 (BASIC KNOWLEDGE OF THEORETICAL FUNDAMENTALS, CALCULATION METHODOLOGIES, BASIC KNOWLEDGE OF METHODOLOGIES APPLIED IN THE LABORATORY PROJECTS), AND THE MAXIMUM GRADE IS 30/30. IN CASES OF PARTICULAR MERIT, THE MAXIMUM MARK CAN BE ADDED "CUM LAUDE" (30 CUM LAUDE). THE EXAM INCLUDES A WRITTEN TEST AND AN ORAL TEST WHICH NORMALLY TAKE PLACE ON THE SAME DAY, PREVIOUSLY SCHEDULED. THE WRITTEN TEST IS PRELIMINARY TO THE ORAL EXAMINATION. THE ORAL TEST INCLUDES THE PRESENTATION OF THE PROJECTS, ON TOPICS INDICATED BY THE COMMITTEE MEMBER.
THE WRITTEN TEST CONSISTS OF ANSWERING THEORETICAL QUESTIONS AND SOLVING NUMERICAL PROBLEMS. THE TEST HAS A DURATION OF NO MORE THAN 120 MINUTES AND IS AIMED AT VERIFYING THE ABILITY TO CORRECTLY APPLY THEORETICAL KNOWLEDGE, THE ABILITY TO UNDERSTAND THE PROPOSED PROBLEMS AND THE ABILITY TO COMMUNICATE IN A WRITTEN MANNER. DURING THE WRITTEN TEST, IT IS NOT ALLOWED TO CONSULT TEXTS OR USE A PC OR SMARTPHONE; A POCKET SCIENTIFIC AND/OR PROGRAMMABLE CALCULATOR IS ALLOWED. THE WRITTEN TEST TAKES PLACE BEFORE THE ORAL TEST 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 DETERMINING 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 OF THE EXPRESSED CONTENTS.
THE ORAL EXAM INCLUDES A DISCUSSION OF LABORATORY PROJECTS PRODUCED BY THE STUDENT INDEPENDENTLY OR IN A GROUP, ON A CASE STUDY PROPOSED BY THE TEACHER AS A LABORATORY ACTIVITY. THE DISCUSSION CONSISTS OF THE PROBLEM STATEMENT DEFINITION, OF THE POSSIBLE PROJECT ALTERNATIVES, REGULATORY CONTEXT, APPLIED METHODOLOGY, DISCUSSION OF THE OBTAINED RESULTS. THE DISCUSSION MAY MAKE USE OF SLIDES AND INCLUDE THE REQUEST FOR THEORETICAL INSIGHTS AND DETAILED CLARIFICATIONS FROM THE MEMBERS OF THE EXAMINATION COMMISSION.
THE EVALUATION OF THE ORAL TEST WILL BE CARRIED OUT ON THE BASIS OF THE FOLLOWING INDICATORS: COMPLETENESS, PRESENTATION, RELEVANCE.
