| Collaborative learning | 36 | 1.44 | CM33, KM42, KM44, SM42, SM43 |
Theory lessons: presentation of the different topics of the syllabus. During theory lessons and as a fundamental part of the learning process examples of application for these topics will also be. presented.
Problem classes: resolution of exercises related to the subject. Discussion with the students about the solving strategies and their execution.
Seminars: practical application of the basis of environmental engineering on environmental sciences. Some exercices will be proposed to be solved in "exam mode" to be evaluated.
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 |
|---|---|---|---|---|
| First exam | 45% | 3 | 0.12 | CM33, KM42, KM44, SM42, SM43 |
| Second exam | 45% | 3 | 0.12 | CM33, KM42, KM44, SM42, SM43 |
| Solved exercices delivery | 10% | 0 | 0 | KM42, KM44, SM42 |
The subject consists of the following evaluation activities:
- Two partial exams including theory and exercices (45% each exam)
- Delivery of exercices solved during the seminars (10%).
Non-participation in any of these evaluation activities will be assessed with a zero.
For a student to pass the subject through continuous assessment it is necessary to obtain a minimum weighted grade of 5 in the global of the subject. To be able to make a weighted average between the delivery of exercices and the grade of the partial tests, a minimum average grade of 4 out of 10 of the partial tests will be required with a minimum mark of 3 in each of the partial tests.
If grade 5 is not achevieved globally, the student may undergo a resit exam only if he/she has been previously evaluated in a set of activities that represent a minimum of two thirds of the total qualification of the subject. The resit exam has two parts, each of them corresponding to one of the partial exams. The student must solve the part (or parts) not passed. In this case, exercices delivering mark remains unchanged. The calculation of the final grade, in the resit process, will be done in the same way as in the continuous assessment and with the same minimum grade criteria.
For each assessment activity with an individual weight of more than 20%, a review place, date and time will be indicated where the activity can be reviewed in person. In this context, claims can be made about the grade of the activity, which will be evaluated by the teaching staff responsible for the subject. If the student does not undergo this review, the activity will not be reviewed later. For the rest of the activities, the student will have a period of 48 hours, from the moment the grade is published, to request a review.
Following UAB regulations, students with a grade of 9.0 or higher in a subject may be qualified by an Honors degree. The number of Honors degrees awarded to students cannot be higher than 5% of the total number of students enrolled in a subject. In this subject, in order to qualify for the Honors degree, in addition to the previous criteria, a grade equal to or higher than 8.5 in each of the assessable activities is needed. Also, students taking any resit exam will be excluded.
A student will be considered non-evaluable (NA) if he/she has not undertaken some of the partial exams or the resit exam.
Students coursing the subject for a second or thirdyear must undergo the above listed evaluation activities.
Without prejudice to other disciplinary measures, and in accordance with current academic regulations, any irregularities committed by the student that could lead to a variation of the score of an evaluation act will be marked with a zero. Therefore, copying or allowing to copy in an evaluation activity will imply a zero (0).
Unique assessment. Students who have accepted the single assessment modality must take a final synthesis test on the date marked in the exam calendar as the second exam. This test will consist of a theory part (30% of the mark) and a problem part (70% of the mark). If the final grade does not reach 5, the student has another chance to pass the subject by means of the resit exam (on the date marked for the make-up exam of the subject).
