Metodi didattici

Frontal lessons and laboratory classes

Laboratory classes will also be performed at Centro Ceramico (via Martelli 26, Bologna).

Modalità di verifica e valutazione dell'apprendimento

Achievements will be assessed by means of an oral examination. This is based on an analytical assessment of the "expected learning outcomes". In particular:

(i) the knowledge of the ceramic process and the main characteristics of ceramic materials as function of their applications;

(ii) the understanding of the main investigation techniques for the determination of the nature and the microstructure of materials as well as for the determination of the mechanical and thermal properties.

The examination also takes into account Laboratory activity.

The oral session consists of a technical conversation with questions by the Professor and answers from the student.

High grades will be awarded to students who demonstrate an organic understanding of the subject and the above-mentioned outcomes, a high ability for critical discussion and a clear and concise presentation of the contents.

A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

Strumenti a supporto della didattica

Videos, power point presentations, traditional blackboard.
