Theoretical classes:

Systemized exhibition of the subject's agenda, giving relevance to the most important concepts. The student acquires the basic scientific knowledge of the subject attending classes of theory, which will complement the personal study of the exposed subjects.


Classroom practices:

Presentation and work on cases or problems of relevance to the learning of the subject. The knowledge acquired in the theory classes and in the personal study apply to the resolution of practical cases that are posed in the seminars. Students work in small groups.


Practical classes:

Practical sessions for the observation and realization of procedures, the practical learning of physiological techniques. It promotes group work and active self-learning.


Use of AI.

For this subject, the use of Artificial Intelligence (AI) technologies is allowed exclusively in support tasks, such as bibliographic or information search, proofreading or translations. The student will have to clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. Non-transparency of the use of AI in this evaluable activity will be considered academic dishonesty and may result in a partial or total penalty in the grade of the activity, or higher penalties in serious cases.

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

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Evaluation of the preparation and presentations of the problems and cases and of works carried out 15% 3 0.12 CM22, CM23, KM27, KM28, KM29, SM23, SM25
Assessment of theoretical knowledge through two objective examinations. These examinations will consist of a combination of multiple-choice questions and essay questions (to assess students' ability to solve problems and provide reasoned explanations). 70% 6 0.24 CM23, KM27, KM28, KM29, SM24, SM25
Evaluation of practical knowledge through tests, analysis of data and tests 15% 3 0.12 CM22, CM23, KM27, KM28, KM29, SM24, SM25

The competences of this subject will be evaluated by means of:


1- Evaluation of theoretical knowledge through objective tests (70% of the final grade)

Two partial evaluations of the subject will be carried out, with a weight proportional to the number of classes given. These tests will consist of development questions and/or multiple-choice questions, where the whole subject matter of the course will be covered. It is necessary to obtain a grade equal or higher than 4,5 in each partial evaluation to consider that part as passed. The parts not passed can be recovered in a final recovery test. An average will only be made with other evaluation activities (calculation of the final grade) when all the tests are passed with a grade higher or equal to 4,5.


2 - Evaluation of the problems, cases and works carried out in the seminars (15% of the final grade).

By their nature, the seminars/case studies are not recoverable activities. Failure to complete a particular seminar will result in a grade of 0.0 for the activity in question. This grade is obtained from the average of the grades of the scheduled seminars.


3- Evaluation of practical knowledge (laboratory) (15% of the final grade).

Practical activities are evaluated on the basis of two activities: i) questionnaires of laboratory practices (5% of the grade, non-repeating students or repieating students which have waived the completion of the practical sessions, see below for details); ii) exams of practical contents (10% of the grade, non-repeating students or repieating students which have waived the completion of the practical sessions, see below for details). A single practice exams will be given at the same time as the second evaluation of theoretical knoledge. The practice exams will not be recoverable.


In order to attend the laboratory practice sessions, the student must prove that he/she has passed the biosafety and security tests that can be found in the Virtual Campus and that he/she is aware of and accepts the rules of operation of the laboratories of the Faculty of Biosciences. The laboratory practicals are compulsory activities according to the regulations of the Faculty of Biosciences.


Practicum grades are not recoverable or modifiable.


- Calculation of the final grade:

Final grade = Weighted grade ofthe theoretical midterm (70%) + Seminar grade (15%) + Practical grade (15%).

The final grade is calculated on the basis of the three evaluation activities indicated above and can only be calculated if in the evaluation of theoretical knowledge each of the three partial grades have been passed with a grade greater than or equal to 4,5.

In case of not being able to calculate an overall final grade for not fulfilling the condition of passing the midterm with a grade higher or equal to 4,5 the student will receive a final grade that will correspond to the lowest grade of the two theoretical knowledge evaluations.

- Repeating students: No grade will be kept from one course to the next. Repeating students can make partial waivers:

(i) Waive the completion of the practical sessions. In this case, they will have to take the practical exam, like the rest of the students, and the grade obtained in the exam will represent their final practical grade (15% of the final grade).

ii) Waiving the seminars. In this case, the final grade will be calculated as theory (85%) + practical (15%).


To participate in the recovery, students must have been previously evaluated in a set of activities the weight of which is equivalent to a minimum of two thirds of the total grade of the course. Therefore, the student will obtain the grade of \"Not Evaluable\" when the evaluation activities performed have a weight of less than 67% in the final grade.


Single evaluation: This subject does not include a single evaluation.


Any irregularity in an assessment activity (academic fraud, plagiarism, or the improper use of AI, unless such use is expressly authorized in the course syllabus) that may result in a significant change to the grade will lead to that assessment activity being awarded a grade of 0. If the course syllabus establishes that obtaining a minimum grade in that assessment activity is an essential requirement for passing the course, or if multiple irregularities occur in the assessment activities of the same course, the final grade for the course will be 0. In addition, disciplinary proceedings may be initiated against any student who commits any of these irregularities.
