EDUCATION METHODS AND ACTIVITIES

Theory and problem classes will be carried out by participatory lectures. In addition, some case studies will be developed between all the students.

Practical classes will be carried out by practical supervision in tutorial classes. Students must develop and deliver along the semester individual reports of the different practicals. There will be an exam in the last session.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

ASSESSMENT

T he assessment of the course will be carried out in the following way:

THEORY EXAM. This exam is composed by two parts: Theory (40%) and practical exercises (60%). The mark obtained in this exam will account for 60% of the final mark of the subject. Both parts must be passed independently.

PRACTICALS. Every group of 20 students will be divided in 5 teams of 4 students. Every team will develop some field works and every student must individually do the calculations of the different practicals preparing some reports which must be delivered along the semester. There will be also an individual written exam in the last practical session. The mark obtained in the report (50%), in the individual exam (40%) together to the continuous assessment by the lecturer/instructor along the semester (10%) will constitute the final mark in the practicals part. This will account for 40% of the final mark of the subject. Practicals reports and final exam must be passed independently to pass the practical part.
