Laboratory Practices: Identification of organisms in an ecosystem. Identification and classification of non-Arthropod Invertebrates. Methods in laboratory work. Use of non-Arthropod Invertebrates to the applied sciences.
Methodology
The methodology used in this course to achieve the learning process is based on student work with available information. The function of the professor is to give the information or indicate where student can get it, helping and supervising the student during the learning process. To achieve this goal, the course is based on the following activities:
Lectures:
In these classes the students acquire the basic scientific-technical knowledge of the course that must be complemented with the personal study of the topics explained.
Seminars:
The mission of the seminars is to promote the capacity for analysis and synthesis, critical reasoning and the capacity to solve problems. Two types of activities are carried out:
1. Conferences with the presence of professionals working on issues related to non-arthropod invertebrates, where the aim is to bring the world of research and business closer to the students of this last grade course.
2. Group work: students have to present a write report from the scientific-technical knowledge exposed in the lectures. It is characterized by the active work of the students. The students are divided into small working groups, and each group chooses a topic previously agreed upon with the faculty, such as the applicability of some zoological groups (Porifera, Cnidarians, Mollusks, Nematodes or Echinoderms), the evolution of some structure of a taxa, etc. Each student works in a group, not admitting any individual work. Each group performs several follow-up tutorials throughout the development of the work. The works are finally exposed to the rest of the class, by all the members of the groups.
Practices:
In the sea practices, students learn in a practical way how marine fauna is studied, and work on the diversity of the invertebrate fauna of the sampled area.
In the laboratory practical sessions, the zoological material is usedto make a guide of identification of the invertebrates’ non-Arthropoda of an ecosystem, and fresh zoological material is identified and classified. The objective of the practical classes is to complete and reinforce the zoological knowledge acquired in the theoretical classes and seminars. In the practical sessions, empirical skills such as the ability to observe, analyze and recognize the zoological diversity are stimulated and developed in the students.
Tutorials:
The objective of these sessions is to solve doubts, review basic concepts not explained in class and guide about the sources consulted by the students. Likewise, these tutorials allow the orientation of the works that will be carried out in the seminars. The schedule of the tutorials is specified with the teaching staff through the virtual campus.
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
ASSESSMENT
To pass the course, a minimum mark of 5 points out of 10 possible is required from the sumatori of theory exam + seminars + practical.
ATTENTION: Attendance to the practices and the seminars is mandatory. Non-attendance to practicals and seminars without justification will imply that the student will NOT be able to pass the subject.
1- CONTINUOUS ASSESSMENT
The programmed continuous assessment activities are:
1.1- THEORY
Partial theory exams: Each of the two partial exams will represent 30% of the final grade and will assess the acquired knowledge during the course, as well as analytical and synthesis skills, and critical reasoning. The exam may include short-answer questions, conceptual questions, or schemes.
• To obtain the average of the two partial exams, the minimum grade for each exam must be equal to or higher than 5.0. If the student obtains a grade lower than 5.0 in a partial exam, student will be allowed to re-assess that examen on the day of the recovery exam. In the case of the exam was not re-assessed, the average cannot be calculated with the rest of the course activities.
Re-assessment of theory exam: This exam will be used to re-assess the necessary partial exams.
• To re-assess an exam, the student must have been evaluated in a set of activities equaling at least at least two-thirds of the total evaluation activities of the course.
• For the theory, to be averaged with the practical and seminar activities, the average of the two partial exams must be equal to or higher than 4.0.
• Students who wish to improve a grade in one or both parts can do the final exam, but they will lose the previous grade.
1.2- SEMINARS
There is an individual evaluation about the conferences, and a group evaluation of the work developed during the seminars. The work and the oral presentation of all the members of each group are also evaluated. The grade corresponding to the seminars will represent 20% of the final grade of the course.
• Attendance to seminars is mandatory.
• This activity cannot be re-assessed.
• For the seminars, to be averaged with the other course activities, the average seminar mark must be equal to or higher than 4.0.
1.3 - PRACTICES
Practices represent 20% of the final grade of the course.
Laboratory and field practices: Attendance at lab sessions and field practices is mandatory.
There are three evaluation activities in the practices:
- Teaching folder:
It consists of a series of learning material that is made during the different activities of practices (outputs and laboratory) and that students accumulate throughout the course. These materials can be the elaboration of an identification guide of an ecosystem, files of follow-up of the exits, field notes of the observations, small tests of evaluation on some practice or exit, etc. In this activity there is no chance for re-assessment.
- Observation record:
The aim is to identify if the students reach competences of a more attitudinal nature through the observation by the professors of their attitude in the different types of activities that take place in the practices (field trips and laboratory sessions). This activity has a value between -1 and 1 that is added in the practical grade reached by the previous evaluations. In this activity there is no chance for re-assessment.
• This activity does not have the possibility to be re-assessed.
• For the practices, to be averaged with the other course activities, the average practices mark must be equal to or higher than 4.0.

1.4- OTHER CONSIDERATIONS
• To pass the course, the final grade must be equal to or higher than 5.0.
• NO ASSESSMENTS: It is considered as not assessed the students who carry out less than 50% of the assessment activities described above.
• For students who do not pass the theoretical part of the course but pass the part of practices and/or seminars (obtaining a minimum of 5 points out of 10), this mark will be kept for a three additional registration periods (but student will have to register for the ENTIRE course again).
• The students who could not attend an individual assessment test for justified reasons (such as a health problem, death of a family member, accident, have the status of elite athlete and have a competition or sports activity with compulsory attendance, etc.) and provide the official documentation corresponding to the professor and the coordination of the degree (official medical certificate stating the incapacity to take an exam, police certificate, justification of the competent sports body, etc.), will have the right to take the test in a later date. The coordination of the degree will ensure for the concretion of this test, after consulting with the professor of the course.
2- SINGLE ASSESSMENT
The students who choose the single-assessment option must request it within the terms and forms indicated by the Faculty.
2.1- THEORY
This part represents 60% of the final grade of the course, and will be evaluated through:
Unique theory exam: The unique theory assessment will consist of an exam that will take place on the day of the 2nd partial exam of the course. The exam may include short-answer questions, conceptual questions, or schemes.
Re-assessment of theory exam: The recovery of the single assessment will be the same day and time that the continuous assessment recovery test.
• For the theory, to be averaged with the practical and seminar activities, the grade of the exam must be equal to or higher than 4.0.
• Students who wish to improve the grade of the exam can do the re-assessment exam, but they will lose the previous grade.
• To re-assess an exam, the student must have been evaluated in a set of activities equaling at least at least two-thirds of the total evaluation activities of the course.
2.2- SEMINARS
IMPORTANT: Even if students choose the unique evaluation, they must attend the seminar sessions of this course.
There is an individual evaluation about the conferences, and a group evaluation of the work developed during the seminars. The work and the oral presentation of all the members of each group are also evaluated. The grade corresponding to the seminars will represent 20% of the final grade of the course.
• Attendance to seminars is mandatory.
• This activity cannot be re-assessed.
• For the seminars, to be averaged with the other course activities, the average seminar mark must be equal to or higher than 4.0.
2.3- PRACTICES
IMPORTANT: Even if students choose the unique evaluation, they must attend the practice sessions of this course. Practices represent 20% of the final grade of the course.
Laboratory and field practices: Attendance at the laboratory practices is MANDATORY and ESSENTIAL to take the unique theory exam.
There are three evaluation activities in the practices:
- Teaching folder:
It consists of a series of learning material that is made during the differentactivities of practices (outputs and laboratory) and that students accumulate throughout the course. These materials can be the elaboration of an identification guide of an ecosystem, files of follow-up of the exits, field notes of the observations, small tests of evaluation on some practice or exit, etc. In this activity there is no chance for re-assessment.

The coordination of the degree will ensure for the concretion of this test, after consulting with the professor of the course.
• Students who have passed the theory part and have a grade of 4.0 or higher in both the practical and seminar parts may take the recovery exam to improve their grade. To be eligible, they must formally renounce (via email) the previous grade, notifying the responsible professor of the course at least three days before the re-assessment exam. The theory grade that will be considered is the one obtained in the most recent exam taken by the student.
