Teaching methods
The lessons will be frontal and will be complemented by online bibliographic research.
Some selected slides among those used to support the lessons will be uploaded weekly on the Elly platform. They represent an integral part of the teaching material
Assessment methods and criteria
Oral examination, to be performed together with Plant Biology (they are a single exam, both modules must be sufficient to overcome it).
Scale of assessment: 0-30
Weights and evaluation criteria:
1) Acquired knowledge (up to 15/30);
2) Ability to apply the acquired knowledge and to make connections between the covered topics (up to 10/30);
3) capacity to communicate concepts through the use of the specific language of the discipline (up to 5/30).
