Teaching method
Theoretical classes with audiovisual media support.
Practical classes which include speciality reports analysis, core logging, powerpoint presentations by students and field trips.
Evaluation method
2 midterm tests (T1, T2) plus a group task (Tg) will be graded and allow to be dismissed from final exam.
The maximum final classification will be calculated as follow:
Final grade: 0,8.(T1+T2)/2 + 0,2.(Tg) = 20 values
Access for the Final Exam will be guaranteed in the case of, at least, 2/3 of attendance of all classes and presentation of the group task.
The frequency of the unit will be valid for the corresponding academic year. In case of failure of the final exam, it will be valid too for the following academic year.
