TECNOLOGIA DEI MATERIALI E CHIMICA APPLICATA

DD1 Knowledge and Understanding: Basic knowledge of materials relevant to civil engineering, correlating their application-related properties with composition, structure, production, and processing technologies.

DD2 Applied Knowledge and Understanding: Ability to apply the knowledge acquired during lectures in the practical exercises carried out throughout the course.

DD3 Making Judgments: Ability to critically evaluate data and parameters in order to make decisions based on one’s knowledge and understanding within the field of materials technology. Ability to tackle and solve complex problems that require the application of knowledge across different areas of materials technology.

DD4 Communication Skills: Students acquire communication skills both during lectures—thanks to continuous verbal interaction with the lecturer—and during the oral examination.

DD5 Independent Judgment: Students learn to objectively evaluate what they have acquired during lectures and exercises, as well as to self-assess their own learning progress.

Learning Skills: Learning abilities are assessed through the oral examination,the ongoing tests and the exercises, which represent an important component of the course.

The course will be done through lectures (3 CFU), ongoing tests and exercises (3 CFU). 

If the course is delivered in blended or remote mode, appropriate adjustments may be made to the above, in order to ensure consistency with the syllabus.

During the school year, second-year students' learning will be assessed through three ongoing tests (two written and one oral). The first (in November 23) will cover the mechanical properties of materials; the second (December 9, 2026) will focus on topics related to metals, polymers, and composites. The third (January 11-12, 2026), an oral exam, will cover topics related to corrosion and alloys. Passing the first exam will allow students to take the second exam, and so on. The final exam (oral), to be passed by September 30, 2027, will cover only topics not covered in the ongoing tests.

Seven regular exam sessions are scheduled throughout the year, plus four sessions reserved for students who have not completed their course of study.

During the periods permitted by the academic calendar, it is also possible to arrange additional exam interviews (held weekly) by contacting the instructor via email or phone.

The final exam (oral) will cover the entire program for those who have not passed any ongoing exams or the portions of the program not covered in the ongoing exams. When contacting the instructor to arrange the interview date, students may indicate their wish to split the final exam into multiple interviews and agree on their content. In any case, the final exam must be passed by September 30, 2027.

How to register for an exam: Booking on the university portal. The date of the interview(s) (which does not coincide with the official exam dates) must be agreed with the instructor by email.

The exam consists of an oral presentation on topics covered during the course. Evaluation is based on the following criteria: knowledge of the required topics (DD1 - DD5), ability to apply knowledge to simple case studies (DD2), ability to connect the various topics of the course (DD3), and expressive ability and language skills (DD4).

Learning assessments may also be conducted electronically, should circumstances require it.

To ensure equal opportunities and in compliance with applicable laws, interested students may request a personal interview to plan any compensatory and/or dispensatory measures based on their learning objectives and specific needs. Students may also contact the CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSA) contact teacher in their department.

The following criteria will be taken into account when assigning the final grade:

• Failed exam: The student does not possess the minimum required knowledge of the main content of the course. The ability to use specific language is poor or non-existent and the student is unable to independently apply the knowledge acquired. • Grade 18–21: the student has minimal knowledge of materials technology, has a modest ability to integrate and critically analyze the situations presented and presents the topics in a sufficiently clear manner although the command of language is poorly developed; • Grade 22–25: the student has a fair knowledge of materials technology although limited to the main topics; is able to integrate and critically analyze the situations presented but not always linearly and presents the topics in a fairly clear manner with a fair command of language; • Grade 26–28: the student has a good knowledge of materials technology, is able to integrate and critically analyze the situations presented, is able to solve complex problems fairly independently and presents the topics clearly using appropriate language; • Grade 29–30 with honors: the student has an in-depth knowledge of materials technology, is able to promptly and correctly integrate and critically analyze the situations presented, independently solving even highly complex problems; has excellent communication skills and language ability.
