Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
The adopted strategy articulates the theoretical classes with practical classes and field work. In practical classes, the theoretical knowledge is applied to study specimens of lichens, mosses and ferns. This material is handled (dissected), observed (using binocular microscopes and microscopes) and drawn. In the field classes collection techniques are trained and in situ diversity observed. In laboratory classes theoretical knowledge is applied, and preparation and observation techniques are trained (including the use of chemical tests to identify lichens).Students are assessed as follows: One written or oral exam covering theoretical topics and concepts (50% final grade, minimum classification 9.5); One practical exam including the preparation, observation, description (including drawings) and identification of specimens (35% final grade, minimum classification 9.5); one herbarium of 30 specimens including laboratory and field notebook (15% final grade, minimum classification 10).
