Seminars
The seminars of this subject will be given in a face-to-face format, if the health and university authorities allow it. They will consist of directed work classes, with videos in some sessions and problem classes.
1. Directed work classes:
In each seminar sessionstudents will work on a glossary of scientific terms, with different methodology,corresponding to the theme / topics that are worked on in the corresponding session and / or related questions. In most cases, the subject / will have previously explained at theoretical classes. The list of the glossary by subjects will be available from the beginning of the course in the CV.
Different activities will be alternated:
- Discussion and correction about the terms of the glossary and exercises / problems delivered in previous sessions and about the questions of the evaluation test carried out in the previous session.
- Group discussion of the resolution of the questions by the students, with the participation of the teacher.
- Preparation by each group of a list of questionsV / F on the subject or topics that has been explained intheory. Discussion and correction of the questions.
- Projection of a video. Analysis and discussion of the video. The student can consult on the web of the subject the transcription of the videos (original in English) that are projected.
- The last quarter of an hour is allocated to an individual assessment test: answering about 10 V / F questions about the subject worked in the seminar or about the video.
The goal of the seminars is to promote the capacity for analysis and synthesis, critical reasoning and the capacity to solve problems.
2. Classes of problems:
The resolution of scientific problems allows a very interesting deduction and integration exercise for the scientific training of the students. The theoretical knowledge is complemented with the resolution of problems related to the topics covered in the theory classes. The compilation of the problems will also be found in the virtual campus in / pdf format. In each problem session each student individually will have to take and deliver the solved problems corresponding to the theme / s that are worked in the corresponding session.
The teacher will ask a student randomly to present theresolution of a problem and explain it to the rest of the classmates with the helpof the teacher.
The goal of the problem classes is to guide the student regarding their level of learning, approaching it to the scientific method and helping the integration of concepts and knowledge.
Practical sessions
The practical sessions of this course correspond to Animal Biology During the practical sessions students will work with zoological material in the laboratory (observation of preparations and specimens, study of anatomy and morphology of groups, dissections, identification of specimens, etc.) and will complement it with the study and the questions posed to the corresponding practice scripts.
The objective of the practical sessions is to complete andreinforce the zoological knowledge acquired in the theoretical classes and seminars. Practical sessions will be stimulated and developed in the student empirical skills such as the ability to observe, analyse and recognize zoological diversity.
At the end of all the practices the students will do an on-line questionnaire about the practical sessions.
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 |
|---|---|---|---|---|
| Laboratory sessions | 14% | 1 | 0.04 | 2, 8, 11, 12, 14 |
| Partial exams | 76% (of which up to 25% will correspond to the marks of the activities related to the theorical sessions) | 6 | 0.24 | 1, 3, 4, 5, 6, 8, 7, 9, 10, 12, 13 |
| Seminars | 10% | 2 | 0.08 | 1, 2, 3, 4, 5, 6, 8, 7, 9, 10, 12, 13, 14 |
The assessment of this subject will be carried out continuously:
Assessment of the master classes:
The assessment of the master classes has a global weight of 76% of the final mark. By this part the knowledge acquired by the student in the subject will be assessed individually, as well as the capacity for analysis and synthesis, and critical reasoning.
This 76% is distributed as follows:
- The part of Animal Biology has a weight of 33%, of which at least 23% will be obtained from the partial exam and up to a maximum of the remaining 10% will derive from the questionnaires that students do at the classroom or in online format (depending on the number of flipped classes done during the course).
- The part of Cell Biology has a weight of 43%, of which at least 28% will be obtained from the partial exam and up to a maximum of the remaining 15% will derive from the questionnaires that students do in the classroom. (depending on the number of flipped classes done during the course).
Therefore, in addition to the evaluation activities throughout the master classes, there will be 2 partial exams. A mark of at least 4.5 out of 10 is required to successfully pass the partial exam.
Second-chance exam: Students who do not pass (with a 4.5) any of the 2 partial exams must be reassessed. Students who, having reached the minimum score to pass the subject, want to upload a mark will also be able to submit to the Second-chance exam. In this case, the note that will prevail will be that of the last exam.
To make the average with the other activities (seminars / problems, practices) it is necessary to reach at least a 4.5 in the Second-chance exam or have successfully passed the two partial exams.
Assessment of seminars /problems:
The assessment of this part consists on both: small works (issues / problems) that should be presented on seminar day and the participation and the assessment tests (by groups or individually) that will be developed throughout the seminar.
This part has a global weight of 10% of the final mark (which is divided into 7.5% of the Animal Biology seminars and 2.5% of the Cell Biology problem classes).
To make the average with the other activities (exams, practices) it is necessary to have a mark of at least 4.
Evaluation of the practical sessions:
At the end of all practical sessions the student will answer an on-line test individually that assesses the use and achievement of the specific skills of each practice. Participation and behaviour in the laboratory classes will also be taken into account.
This part has a global weight of 14% of the final mark.
To make the average with the other activities (seminars / problems, exams it is necessary to have a mark of at least 4.
Not assessable:
A student is considered not assessable if he participates in assessment activities that represent less than 15% of the total mark.
This course does not foresee the one single assessment system.
