Modalità di verifica e valutazione dell'apprendimento

The assessment of the teaching activity will be performed through both a written test and an oral exam.

The written test is composed by 20 questions, 5 with an open response and 15 with multiple choices responses. The open questions are worth to have maximum 5 points each, while in the multiple choices response a correct answer allows to gain 1/2 while a wrong response give -1/2; no response corresponds to 0.

A positive mark on the written test is a prerequisite for being admitted to the oral.

The oral exam is performed after some days and can be performed in two ways:

  • an oral exam with questions on specific parts of the program;
  • discussion of an individual project work previously agreed with the teacher on a topic discussed during the semester.

The mark of the written test is considered as a basis for the final vote that is given after the oral exam.
