| Verification of learning | |
|---|---|
| THE EXAM IS AIMED AT ASSESSING, OVERALL, THE ACHIEVEMENT OF THE SET LEARNING OBJECTIVES BY VERIFYING THE KNOWLEDGE AND UNDERSTANDING OF THE CONCEPTS PRESENTED AND DISCUSSED DURING THE LECTURES, AS WELL AS THE ABILITY TO APPLY SUCH KNOWLEDGE TO THE DESIGN OF AN EMBEDDED SYSTEM CAPABLE OF OPERATING IN THE E-HEALTH FIELD. THE FINAL TEST INCLUDES THE DEVELOPMENT AND PRESENTATION OF A GROUP PROJECT ON A TOPIC ASSIGNED BY THE INSTRUCTOR AND AN INDIVIDUAL ORAL INTERVIEW. THE PROJECT PRESENTATION WILL TAKE PLACE THROUGH THE SUBMISSION OF A REPORT, FOLLOWED BY A GROUP PRESENTATION DURING WHICH STUDENTS WILL BE ASKED TO DISCUSS THE IDENTIFIED SOLUTIONS, THE METHODS ADOPTED, AND THE ACHIEVED RESULTS. THE EVALUATION WILL CONSIDER EACH STUDENT’S ABILITY TO ANALYZE AND UNDERSTAND THE ASSIGNED PROBLEM, TO IDENTIFY SUITABLE DESIGN CHOICES AND IMPLEMENT THEM EFFICIENTLY BASED ON THE KNOWLEDGE ACQUIRED DURING THE COURSE, THE ABILITY TO PRESENT THE WORK IN A COMPLETE AND EXHAUSTIVE WAY, THE DEMONSTRATION OF CORRECT AND VALID RESULTS WITHIN THE DEFINED APPLICATION CONTEXT, AS WELL AS THE ABILITY TO WORK IN A TEAM. THE ORAL INTERVIEW WILL BE MAINLY AIMED AT VERIFYING THE OVERALL KNOWLEDGE OF THE SUBJECT MATTER OF THE COURSE THROUGH A DISCUSSION ON THE THEORETICAL TOPICS, WHETHER OR NOT RELATED TO THE ISSUES ADDRESSED DURING THE PROJECT IMPLEMENTATION. THE FINAL GRADE, EXPRESSED OUT OF THIRTY WITH POSSIBLE HONORS, WILL EQUALLY TAKE INTO ACCOUNT BOTH THE PRESENTATION AND DISCUSSION OF THE PROJECT AND THE INDIVIDUAL INTERVIEW, AND WILL ALSO DEPEND ON THE STUDENT’S COMMUNICATION SKILLS, THE QUALITY OF THE PRESENTATION, INDEPENDENT JUDGMENT, AND LEARNING ABILITY. |
