Teaching method
Teaching is provided by theoretical-practical sessions of 4 hours each where it is present technical concepts whenever possible with documented examples, and resolve quantitative problems. Field trips are planned to ornamental stone and aggregates quarries. All information and presentations are available on the Web (CLIP).
Evaluation method
The evaluation is carried out by two tests of two hours each in the class period or final exam on the scheduled date plus 2 individual works. There is no minimum grade in the tests. Tests have 80% of grade (40% each) and the two works the remaining 20% (10% + 10%). There is no frequency. There is no minimum score in the tests or in the works.
