AIMS AND CONTENT

LEARNING OUTCOMES

Main objective of this course is the description of properties and characteristics of inorganic materials on the basis of relations between structure, microstructure and chemical and physical properties. Moreover correlation between contitutional properties and behaviour in service under different conditions are described.

TEACHING METHODS

Frontal lessons

EXAMS

EXAM DESCRIPTION

Final oral exam.
The oral exam is always conducted by two tenured teachers, lasts at least 30 minutes and focuses on all the topics covered in class.
At the student's choice, it can consist of:
a) several questions posed by teachers on the topics covered in class
or
b) seminar held by the student on a topic agreed with the teacher and a few questions posed by teachers on the topics covered in class

 

ASSESSMENT METHODS

With the methods described above, given that at least one of the two teachers has many years of exams experience in the discipline, the commission is able to verify with high accuracy the achievement of the educational objectives of the teaching. When these are not reached, the student is invited to deepen the study and to make use of further explanations by the lecturer. The CCS guarantees the correspondence between the topics of the exam and those actually carried out during the course. To this end, the teacher in charge makes the detailed program public at the beginning of the lessons (on a site called the web room reserved for teachers and students of the University).
