Assessment methods

MODULE 1 – MECHANICAL PLANTS

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 two hours, and composed of three questions, of which at least one being about plant P&I.

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.

Usually the written test correction immediately follows the written test end. So, it is possible to make further oral questions to the students to better assess their skills and to better define the final evaluation.

MODULE 2 - LOGISTICS

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 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.
