Teaching Methodologies and Assessment Criteria The CU is taught during the first semester, involving 30 hours of contact with the teacher and 180 hours of autonomous student work (total: 210 hours). The approval to the UC grants the trainee 7.5 ECTS. The classes, from the theoretical-practical typology (TP), contemplate the brief theoretical exposition of the syllabus contents, the resolution accompanied by exercises and the discussion and analysis of conceptual questions, serving as the basis for the development of a final practical work of an individual nature and autonomous, that aims at the resolution of an exercise of spatial analysis, using the GIS tools and applying a large part of the theoretical knowledge given. The evaluation is carried out through supervised assignments (10%), an individual and autonomous practical assignment (40%) and a final exam (50%) for the students admitted. The evaluation criteria may be reviewed annually, according to the UBI RGAC.
Language Portuguese. Tutorial support is available in English.
