Teaching methods

The teaching activities are conducted through lectures (48h) supplemented by in-depth tutoring and tutoring seminars (12h).
The slides used to support the lessons will be uploaded to the Elly platform.
The slides are considered, together with the reference texts, an integral part of the teaching material. Non-attending students can check the teaching materials available through the Elly platform.

Assessment methods and criteria

The methods for verifying learning consist of:
- in the critical discussion of the reports related to the experiments conducted in the laboratory, with a scale of 0-30 and weight 0.25
- in a written test with open answers, with a scale of 0-30 and weight of 0.25.
- in an oral exam by means of interrogation, with an evaluation scale of 0-30 and weight 0.50
For the dates of the appeals (winter session February, summer June-July, autumn September 2018) see Esse3
