Formative assessment
The exercises in the classroom and in the laboratory, as well as discussions with the professor during the lectures would allow to assess and evaluate the student ability to apply their knowledge and understanding of the topics covered during the course.
The expected ILOs assessed during the formative assessment are summarized in the following (refer to the list in the "expected learning outcomes" field):
- ILOs assessed by means of discussions with the professor: 2, 11, 13, 14.
- ILOs assessed by class exercises and laboratory activities: 1, 3, 6, 9, 10, 12, 14.
Criteria, rules, and procedures for the final examination
The final examination consists of two distinct written parts, which the student must take in succession (i.e. in the same day): one part aims to assess the contents concerning assembly technology; second part to assess the contents concerning manufacturing processes.
Each written part consists of 10 questions inherent to the topics addressed during the course (both during the frontal and exercise lectures, as well as lab activities). Therefore, the whole exam consists of 20 questions. The questions can be multiple choice questions, open-ended questions and/or exercises to be solved.
Each written part can be successfully passed if the student reaches 18/30 (answers are rated from 0 to 3 points each).
Score of 18/30 in both the written parts is a mandatory to pass the whole exam, otherwise it is failed.
In case of passing only one of the two tests, students can keep the good one till the first exam session of the next academic year (January - February).
The expected ILOs assessed during the final exam are (refer to the list in the "expected learning outcomes" field): 1-8, 10, 13.
Evaluation criteria and criteria for awarding marks
The evaluation criteria of the written exam are based on the correctness of the responses to multiple choice questions and exercises, and pertinence and clarity of the response to the open-ended questions.
The grade for each written part is expressed in a 30/30 scale.
The student can present the results of a teamwork activity (a team normally consists of 4-6 students) in order to increase the final grade of further 1/30 to 3/30 points. In the teamwork activity, students must design autonomously an assembly or a manufacturing process to fabricate an industrial component assigned by the professor. The teamwork activity lasts about 1.5 months (approximately from the beginning of May to mid-June). Students must make an oral presentation, always planned before the first exam session, to present and discuss the results of the teamwork activity. The evaluation criteria of the teamwork are based on the knowledge of the topics of the course, the clarity and the properties of language of students, the pertinence and the relevance to the answers of the professor, and the autonomy of judgment. Teamwork activity is optional and not compulsory.
Summarizing:
final score = [score of manufacturing test (expressed in xx/30 with a minimum of 18/30) + score of assembly test (expressed in xx/30 with a minimum of 18/30)] /2 + teamwork score (from 0 to 3/30).
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.

Formative assessment
Classroom exercises, laboratory activities, and discussions with the professor during lectures will provide opportunities to assess and evaluate students' ability to apply their knowledge and understanding of the topics covered in the course.
The expected ILOs assessed during the formative assessment are as follows (refer to the list in the "expected learning outcomes"):
- ILOs assessed through discussions with the professor: 2, 11, 13, 14.
- ILOs assessed through classroom exercises and laboratory activities: 1, 3, 6, 9, 10, 12, 14.
Criteria, rules, and procedures for the final examination
The final examination consists of two distinct written parts, manufacturing and assembly parts, which must be taken consecutively on the same day. The first part assesses the contents concerning manufacturing processes, while the second part assesses the contents concerning assembly technologies.
The Manufacturing part (70 min) consists of two tasks inherent to the topics addressed during the course:
- a multiple-choice quiz of 8-10 questions (30 min) about manufacturing topics. For each question, the student must choose 1 or 2 correct answers from 5 alternatives proposed. A penalty from -0.1/30 to -0.5/30 points is given for each wrong answer, depending on the difficulty of the question. Not answered questions have no penalties.
- 2 exercises (40 min) about manufacturing topics.
The Assembly part (70 min) consists of two tasks inherent to the topics addressed during the course:
- a multiple-choice quiz of 8-10 questions (30 min) about assembly topics. For each question, the student must choose 1 or 2 correct answers from 5 alternatives proposed. A penalty from -0.1/30 to -0.5/30 points is given for each wrong answer, depending on the difficulty of the question. Not answered questions have no penalties.
- 2 open-ended questions (40 min) about assembly topics.
In both Manufacturing and Assembly parts, students are not allowed to use textbooks, notes, blank sheets, or electronic devices (such as tablet, smartphone, smartwatch, etc.). Only calculators, pencils, pens, and erasers are permitted. Blank sheets are provided by the professor.
Each part can be successfully passed if the student achieves a minimum score of 18/30. Both parts must be passed with at least 18/30 to pass the whole exam, otherwise the exam is failed.
If a student only passes one of the two parts (e.g., Manufacturing) but fails the other (e.g., Assembly), the overall exam is failed. However, the student can keep the passing score for the next exam sessions and retake only the failed part (ex. Assembly). When both parts are passed successfully, the overall exam can be registered. Note that this opportunity is only valid until the beginning of the course in the next academic year (about the end of February). After that, any previously earned marks for a single part will expire.
The expected ILOs assessed during the final exam are (refer to the list in the "expected learning outcomes"): 1-8, 10, 13.
Evaluation criteria and criteria for awarding marks
The evaluation criteria of the exam are based on the correctness of the responses to multiple choice questions and exercises, and the pertinence and clarity of the response to the open-ended questions.
The grade for each part is expressed in a 30/30 scale.
Final grade
The final grade is computed as the arithmetic mean of the scores obtained from the Manufacturing and Assembly part. The final grade is rounded to the nearest integer: the grade is rounded down if the first digit is less than 5; the grade is rounded up if the first digit is 5 or greater. A final grade of 30 cum laude is awarded only if the student passes with a score of 30/30 on both the Manufacturing and the Assembly parts.
Exam results are communicated to students on the didactic portal, generally within 4-5 working days.
Students can review their graded exams during a meeting with the professor. The meeting date will be communicated to the students by notice on the didactic portal before each exam session.
Examples of previous exam formats and exercise solutions are available on the course portal.
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.
