Assessment
Evaluation
(a) Scheduled evaluation process and activities
The following are the activities of evaluation of the subject with its percentage of weight on the final grade:
- Activity 1 (16.7%). Themes 1,2. Work
- Activity 2 (23.5%). Themes 3,4,5. Works.
- Activity 3 (3.3%). Theme 7. Work or Classroom activity.
- Activity 4 (24.5 %). Exam with contents of Themes 1,2 (16.6%), 3,4,5 (7.9%)
- Activity 5 (32 %). Exam with contents of Themes 6 (5.6%), 7 (9.7%), 8 (9.3%) and 9,10 (7.4%).
The non-presence in class when evaluation tests are carried out is a zero of the activity, without possibility of recuperation.
b) Programming of evaluation activities
The schedule of evaluation activities will be given on the first day of the course and will be made public through the Moodle.
(c) Recovery process
A student who has a weighted average score for continuous assessment activities of less than 5 must take a make-up exam. The student may take a make-up exam provided that he/she has taken a set of activities that represent a minimum of two-thirds of the total grade for the course. Make-up will consist of a face-to-face examination including content from all continuous assessment activities where the student has a score of less than 5. The final grade of the make-up will be a weighted average (according to the same percentages of the continuous evaluation) between the grade of the make-up exam and the grade of the continuous evaluation activities previously approved. In order to make this weighted average, the student must obtain a minimum grade of 4 on the make-up exam.
d) Grade review procedure
For each assessment activity, a place, date and time of review will be indicated where the student can review the activity with the professor. In this context, complaints can be made about the grade of the activity, which will be evaluated bythe professor responsible for the subject. If the student does not submit to this review, this activity will not be reviewed at a later date.
e) Qualifications
Honor plates. Awarding an honor roll grade (MH) is the decision of the faculty responsible for the subject. UAB regulations state that MH can only be awarded to students who have obtained a final grade of 9.00 or more. Up to 5% of the total number of students enrolled may be awarded.
A student will be considered non-assessable (NA) if he has not presented to a set of activities the weight of which equals a minimum of two thirds of the total grade of the subject.
f) Student Irregularities, Copying and Plagiarism
Without prejudice to other disciplinary measures that may be deemed appropriate, irregularities committed by the student that may lead to a variation in the grade of an evaluation act shall be graded with a zero. Therefore, copying, plagiarism, cheating, letting copy, etc. in any of the evaluation activities will involve suspending it with a zero. Evaluation activities graded in this way and by this procedure will not be recoverable.
h) Evaluation of Repeating Students
There are no changes in the evaluation of the repeating students.
