Theoretical classes:
Systematized presentation of the subject's program, giving relevance to the most important concepts. The student acquires the basic scientific knowledge of the subject by attending theory classes that will be complemented with the personal study of the exposed topics.
Classroom practices:
Work on cases and/or problems relevant to learning the subject. The knowledge acquired in theory classes and personal study is applied to the resolution of practical cases that arise. Students work in groups.
Laboratory course:
Practice sessions for the observation and performance of procedures, practical learning of physiological techniques. Group work and active self-learning are promoted.
In order to attend the laboratory practice sessions, the student must prove that they have passed the biosafety and safety tests that they will find on the Virtual Campus and be familiar with and accept the operating standards of the laboratories of the Faculty of Biosciences.
Tutorials:
Individual sessions or in small groups to resolve doubts related to the subject. This type of activity will be carried out at the request of the students (individually or in groups) or will be proposed by the teacher on a voluntary basis. Therefore, it is an activity that will not be valued in the count of hours included in this teaching guide.
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.

- Evaluation of practical competences acquired through the resolution of problems and theoretical exam questions.
- Evaluation of theoretical competences by means of objective tests of multiple answer and in some aspects questions of development of the proposed objectives. It is indispensable to get a grade equal to or greater than 5 to consider the partial part of theoretical knowledge achieved.
- Evaluation of problems based on the results in the case of the problems and the capacity of synthesis and brief explanation in the resolution of questions posed.
- Possibility of recovering only those parts of the theoretical competences that were not obtained at the time.
- The modification of the overall grade of the subject can be done by means of the resolution of a synthesis examination (one question) of the entire subject, which implies the renunciation of the previous note
- Repeaters that do not carry out a continuous assessment, that is to say, do not face problems and / or practice sessions must notify the teaching staff at the beginning of the course, the others will have to do the continuous assessment just like the other classmates, they will have To carry out the practice exam and the mark of the subject will be calculated as 85% theoretical concepts and 15% practical.
To participate in the recovery, the students must have previously been evaluated in a set of activities whose weight equals to a minimum of two thirds of the total grade of the subject or module. Therefore, students will obtain the "Non-Appraising" qualification when the assessment activities carried out have a weighting of less than 67% in the final grade ".
