Teaching Methods
THE COURSE CONSISTS IN FRONT LESSONS (60 H) AND CLASSROOM EXERCISES (30 H) FOR A TOTAL AMOUNT OF 90 HOURS WHICH ARE WORTH 9 CREDITS.
ATTENDANCE AT THE LECTURES IS STRONGLY RECOMMENDED
Verification of learning
THE EVALUATION OF THE ACHIEVEMENT OF THE EXPECTED OUTCOMES WILL BE CARRIED OUT WITH A SCRIPT AND AN ORAL INTERVIEW.
THE ASSESSMENT OF THE LEARNING OUTCOMES, CARRIED OUT IN THE FINAL EXAMINATION, WILL TAKE INTO ACCOUNT THE FOLLOWING EQUIVALENT CRITERIA: A) KNOWLEDGE AND ABILITY TO SOLVE MAJOR ISSUES THAT REQUIRE THE APPLICATION OF EXPRESSED CONCEPTS; B) KNOWLEDGE OF THE BASIC ASSUMPTIONS AND LOGIC OF THE DISCIPLINE; C) ABILITY TO EXTEND THE APPLICATION OF BASIC CONCEPTS TO SOLVE ISSUES IN NEW APPLICATIONS, D) PROPERTY OF LANGUAGE WITH PARTICULAR REFERENCE TO THE SPECIFIC TERMINOLOGY OF THE DISCIPLINE.
THE EXAM WILL BE EVALUATED SUFFICIENT WHEN THE STUDENT IS ABLE TO SET THE DESIGN OF THE OPERATIONS UNIT, USING PROPERLY ALTHOUGH NOT READILY PHYSICAL AND CHEMICAL-PHYSICAL VARIABLES INVOLVED, AND IF IT SHOWS SUFFICIENT KNOWLEDGE OF THE VOCABULARY OF THE SUBJECT. THE STUDENT WHO SUCCESSFULLY PROJECTS, WHICH HAS FULL AND READY PERCEPTION OF THE EFFECTS OF THE DESIGN VARIABLES AND SHOWING MASTERY OF THE SUBJECT LEXICON IS RATED AS EXCELLENT.
