Assessment methods and Criteria
The exam consists of an oral discussion on the topics covered during the lessons and on a written report. The exam starts from the report (to be delivered to the professor not later than 7 days before the exam), elaborated by the candidate on a free choice area. The report must contain a geomorphological map, a description/discussion on the peculiarity of the area in terms of geomorphological processes, activity degree, geomorphological hazards, vulnerability elements and geomorphological risks scenarios. Moreover, the ability of recognizing geomorphological elements through images will be tested.
The evaluation parameters will be the comprehension of the concetps, the correctness of contents and language, the appropriateness of language, the ability of rielaborating concepts by means of report, geomorphological map and relative discussion.
