MATERIAL TECHNOLOGY AND APPLIED CHEMISTRY

Knowledge and understanding: Basic knowledge of materials of interest for civil engineering, correlating their application characteristics to composition, structure, production and processing technologies

Applied knowledge and understanding skills: Ability to apply what has been learned during the lectures in the exercises carried out during the course.

Autonomy of judgment: Students learn to objectively evaluate what they have learned during lessons and exercises.

Communication skills: Students acquire communication skills that are formed both during the lessons, thanks to a continuous verbal conversation with the teacher, and during the oral exam.

Learning skills: Learning skills are assessed through the oral exam and exercises which are an important part of the course.

The course will be done through lectures, ongoing tests and exercises. If course should be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

6. 5. Class notes

During the lesson period, learning will be verified through three in itinere tests (two written and one oral). The first (October 24, 2022) will concern the mechanical properties of materials; the second (23 November 2022) will focus on topics related to metals, polymers and composites. The third (22-23 December 2022), in oral form, will concern the exposition of topics related to corrosion and binders. Passing the first test will allow you to go to the second and so on. The final exam (oral), to be passed within one calendar year from the date of passing the first test, will focus only on the topics not covered in the ongoing tests

During the year, seven (ordinary) exam sessions are scheduled plus four sessions reserved for out-of-course students.

During the periods allowed by the academic calendar it is also possible, by contacting the teacher by e-mail or by telephone, to arrange further exam interviews (on a weekly basis)

The final exam (oral) will focus on the whole program for those who have not passed any ongoing tests or on the portions of the program not acquired with the ongoing tests. When you contact the teacher to agree on the date of the interview, you can communicate your desire to divide the final exam into several interviews and agree on the contents. In any case, the final exam must be passed within one calendar year of passing the first interview.

How to register for an exam session: Booking on the university portal

The exam consists in the oral presentation of topics addressed during the course

The evaluation of the exam is based on the following criteria: level of knowledge of the required topics, expressive ability and language properties, ability to apply knowledge to simple case studies, ability to connect the different themes of the teaching program.

Verification of learning can also be carried out electronically, should the conditions require it.
