It is a subject corresponding to a curriculum in extinction, this course does not program classes in theory or problems. Repeating students who enroll in the subject may have tutorials, with the responsible teacher, to address the queries and doubts of the syllabus and the resolution of problems
The studients have to do a work on a topic related to the subjetc
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Assessment
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |
|---|---|---|---|---|
| Activity A | 45 | 2 | 0.08 | 1, 2, 3, 4, 8, 9, 10 |
| Activity B | 35 | 2 | 0.08 | 1, 2, 3, 4, 8, 9, 10 |
| Activity C | 20 | 1 | 0.04 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 |
a) Process and scheduled evaluation activities
- Activity A. Written test on the content of topics 1 and 2. The weight will be 45% of the final grade.
- Activity B. Written test on the content of topics 3 and 4. The weight will be 35% of the final grade.
- Activity C. Work. Students must submit a written work that will have a weight of 20% on the final grade. This activity is not recoverable.
To pass the course, through continuous assessment, a minimum grade of 4 will be required in activities A and B.
The note will result from the following expression:
Final grade (continuous assessment) = Activity grade A (≥4) * 0.45 + Activity grade B (≥4) * 0.35 + Activity grade C * 0.2
b) Scheduling of evaluation activities
The schedule of the evaluation activities will be communicated at the beginning of the course.
c) Recovery process
Students who have not passed the subject will be able to present themselves to the recovery of activity A and / or B, provided they have been presented to a set of activities that represent a minimum of two thirds of the total mark for the subject and have a average mark of all the activities of the subject higher than 3.
According to the coordination of the Degree and the management of the School of Engineering, Activity C (work) is not recoverable.
The recovery note will result from the following expression:
Final grade = Activity grade A (≥4) * 0.45 + Activity grade B (≥4) * 0.35 + Activity grade C * 0.2
Those students suspended for not having reached the minimum grade (in any of the activities) will have a maximum final grade of 4.
d) Qualification review procedure
For each assessment activity, there will be a review place, date and time where the student can review the activitywith the teacher. In this context, it will be possible to make claims about the grade of the activity, which will be evaluated by the teacher responsible for the subject. If the student does not appear for the review, this activity will not be reviewed later.
e) Qualifications
With honors. Up to 5% MH of the total number of students enrolled can be awarded. It can only be awarded to students with a final grade equal to or greater than 9.5.
A student will be considered non-assessable if he / she has not submitted to any evaluation activity of the subject
f) Irregularities on the part of the student, copying and plagiarism
Without prejudice to other disciplinary measures deemed appropriate, the irregularities committed by the student that may lead to a change in the grade of an act of evaluation will be rated with zero. Therefore, copying, plagiarism, cheating, letting yourself be copied, etc. in any of the evaluation activities it will involve suspending it with a zero.
g) Evaluation of repeating students
Students who do not enroll for the first time in the course will have the option of taking the assessment activities during the course or the recovery activities at the end of the course.
The grade of the subject will correspond to the following result:
Final grade = Activity grade A (≥4) * 0.45 + Activity grade B (≥4) * 0.35 + Activity grade C * 0.2
