Modalità di verifica e valutazione dell'apprendimento
The assessment will be performed through a written test and an oral presentation.
The written exam will be composed of both open and closed questions with around 20 questions. The time is 90 minutes.
For the oral presentation students are organized in groups depending on their preferred macro-topic. Each group is asked to prepare a high-level (survey/tutorial style) presentation for end of April (one day will be devoted to students presentation and discussion). Each student prepares a specific presentation for the final exam discussing one single topic (e.g., one technique, one protocol, one service). During the final exam we will discuss also on the written test about possible mistakes.
The final score will be the written score + 4 points depending on teh quality of the two presentations (2 point for the group presentation, 2 for the personal presentation).
Students having attended in the previous year can contact me for previous assessing methods.
