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

At the end of the semester, the student has to choose between two methods of evaluation: OVERALL EVALUATION or FINAL EXAM.

OVERALL EVALUATION

This assessment method is organised according to the activities described in the previous table. The evaluation process consists of:

- The evaluation of the tasks defined in the Teaching Guide during the Teaching period.

- A final Written Exam during the Examination period.

The assessment aspects evaluated in both parts and their contribution to the final mark are summarized in the following table:

Aspect	Teaching period	Final Exam	Total by aspect
S1 Attendance and participation	10 %	-	10 %
S2 Theoretical concepts	15 %	15 %	30 %
S3 Exercises, problems and study cases	15 %	15 %	30 %
S4 Laboratory or computer practical work	30%		30 %
Total for the subject	70 %	30%	100%

 

Marks obtained during the Teaching period (as a record of the continuous evaluation process) will be kept until the end of the academic year.

Written Exam

The students have to make a Written Exam that assesses the theoretical and operating aspects of the subject (S2 and S3) at the end of the semester (at the date established in the examination period). This final evaluation is made to assess the extent to which the students have acquired all the competences and learning outcomes established for those aspects. The weight of this exam is the 50% of each of the evaluated aspects (S2 and S3).

Any books, notes, documentation, or equipment allowed for this Final Exam have to be approved by the lecturer.

Final assessment

The students must obtain a mark higher or equal to 4 (out of 10) in S4 to keep this evaluation method (Laboratory or computer practical work). The students will pass the subject through this evaluation method by getting a mark higher or equal than 5.0 out of 10 in the overall result (continuous evaluation and written exam), but with the condition of obtaining a mark higher or equal to 4.0 in the Written Exam and in S4.

The students can renounce to the Overall Evaluation at any time, but they cannot choose it again. Thus, they will be evaluated only by the FINAL EXAM method.

FINAL EXAM EVALUATION

This kind of evaluation is based in only one written exam that evaluates all the aspects of the subject, by assessing the students' acquisition of all the competences and learning outcomes established in the subject. This exam will take place during the Examination period on a date established by the centre. The final exam is weighted in the following way:

- Attendance and participation (S1), theoretical concepts (S2) and Exercises, problems and study cases (S3): 70%.

- Laboratory and computer practical work (S4): 30%.

 

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 at each part of the final exam.

The students who have already fulfil the requirements of aspect S4 (Laboratory or computer practical work) through the OVERALL EVALUATION, by obtaining a mark higher or equal to 5.0 out of 10 do not have to make this part in the FINAL EXAM evaluation.

Those aspects successfully completed with a mark higher or equal to 5.0 will be considered passing during that academic year.

 

The OVERALL EVALUATION modality consists of the following activities:

Attendance and Active participation: 10%. The level of attendance will be computed considering practical (reduced groups) and theoretical/problems sessions (lectures with theory groups). The level of active participation will be evaluated via the students participation and autonomous work in various proposed activities within lectures and lab sessions. The following competences will be evaluated with this method:  CB6, CB7, CB8, CB9, CB10, CG1, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  34, 40, 41.

 

Theoretical concepts: 30%. At the end of the semester (final exam date proposed by the center), there is a written exam about theoretical questions developed during lectures. In addition, the continuous evaluation related to the questions proposed as autonomous work or through ILIAS (LMS). The following competences will be evaluated with this method: CB9, CB10, CG2, CG3, CG4, CT1, CT2, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

Exercises and case studies: 30%. At the end of the semester, there is a written final exam with the problems and practical cases studied in lectures. In addition, the development and presentation of the material related to activities proposed through the LMS is also evaluated (continuous evaluation). The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

Lab/computer practical sessions: 30%. This item takes into account the development of the design practices and the documentation requested. The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

The grade system is ruled by RD 1125/2003 of 5th September, which established the European Credits System for the official university studies.
