Teaching methods

Part 1

On the whole 60 teaching hours of frontal lessons and training corresponding to 6 ECTS. The main target is to give the student the right approach the dimensioning of facilities inside an industrial plant, according to economical evaluation and technical rules

Part 2

The course consists of 3 ECTS lectures and more practical exercises in the classroom , for a total of 30 hours, with testimonies and seminars on specific topics.

Practical exercises on Ergonomics will be carried out in teams, both in the classroom than in external companies.

Assessment methods

For students enrolled in module1 and module 2 from 9 total ECTS

Achievement will be assessed by the means of a final exam. This is based on an analytical assessment of the “expected learning outcomes” described above.

In order to properly assess such achievement the examination is based on a written test, lasting up to three hours including the theoretical and practical development of three arguments , two of which theoretical issues ( whether the issue is one from module 1 and one from module 2 ) and a numeric - themed application.

The rating is assigned based on the overall assessment of the whole test.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents, with particular attention to the use and the comprehension of technical terms, graph, diagrams related to the service plants and the safety on work.

To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

A failing grade will be awarded if student shows knowledge gaps in key-concepts of the subject, inappropriate use of language and logic failures in the analysis of the subject. Then the exam result not sufficient if at least one question is not sufficient.

Teaching tools

Issues provided by the teaching staff and provided on line on AMS Campus and Universibo portals both

Seminars on specific topics of Safety (i.e. Ergonomics) and successfull case studies will be carried out during the course.
