... Before taking the exam specific reports about selected project activities have to be submitted for evaluation. Four (4) projects are assigned to each team during applied lectures, i.e. 4 reports have to be submitted. Deadline for the submission of each report is also established during applied lectures, In general, all reports have to be submitted before the start of summer examination session. If exam is not taken before the end of the current A.Y., a new project set has to be assigned, prepared and submitted. The exam consists in two parts (both oral tests): Part A: discussion of the report + one question (mainly about topics related to applied lecture) -> Score A (out of 30) Parte B: one/two questions (mainly about topics discussed during lectures) ?> Score B (out of 30) Baseline score (out of 30) =(𝐒𝐜𝐨𝐫𝐞 𝐀 + 𝐒𝐜𝐨𝐫𝐞 𝐁)/𝟐 Extra points: up to three, based on the global evaluation of the reports Final score = Baseline score + extra points Part A and part B have to be taken in the same day, one after the other Average duration of exam (A+B): 1-1.5 h
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam; Group project;
Team projects (Elaborato progettuale di gruppo) At the beginning of the course, students will be divided in teams of two-three people. Each team has to carry out four (4) projects that are assigned during applied lectures. A report has to be submitted for evaluation for each project. , i.e. 4 reports have to be submitted. Deadlines for the submission of each report are established during applied lectures at the beginning of the course, so that all reports are submitted before the start of summer examination session. If exam is not taken before the end of the current A.Y., a new project set has to be assigned, prepared and submitted in the next A.Y.. After submission, each project will be evaluated with a score (out of 30). The score of each project and a detailed evaluation of the report will be published in due time, i.e. before the deadline for the next report, so that students can take suggestions into account before writing and submitting the report of the next project. The resulting average score of all the projects will be published before the start of the 1st exam session after the end of the course. Oral test (Prova orale obbligatoria) The exam consists in an oral test with one/two questions about topics discussed during lectures. A discussion of the reports can be required. Final score (out of 30) = (Project score + oral test score) / 2
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
