Introduction to Marine Engineering, Revised 2nd Edition 2nd Revised Edition by D. A. Taylor

Teaching methods

Teaching includes: theoretical lectures delivered with the aid of multimedia systems. The teaching material is made available on virtuale.unibo.it.

Attendance is recommended for better learning of the concepts and notions.

Exercises may be assigned during the course for in-depth study of product development techniques.

Assessment methods

The assessment of the students' acquired knowledge takes place through an oral interview lasting approximately 15-20 minutes. During the examination, the candidate will be asked to answer two or three questions covering the main topics covered in the course. The questions will be formulated so as to test understanding of the key concepts and the ability to apply them critically. In order to prepare best, it is advisable to refer to the slides provided during the lectures, as these form the basis from which the discussion will start. The purpose of the interview is not only to ascertain learning, but also to stimulate dialogue and discussion of any doubts or insights.
