Methodology
Teaching methodology of the course
LECTURES:
The topics of the different blocks will be taught in approximately 30 sessions. Some of the sessions will be given by guest lecturers and specialists in the field of clinical research of diseases caused by pathogens. The content of the theory program will be taught by the professor responsible for the course in the form of lectures with audiovisual support. The presentations used in class by the professor will be previously available in the Virtual Campus of the subject.
AUTONOMOUS LEARNING:
Autonomous learning will be based on achieving the specific learning competencies that will accompany the beginning of each block in which the program of the subject is divided. Students are advised to regularly consult the books recommended in the bibliography section of this teaching guide to consolidate and clarify, if necessary, the contents explained in class.
COOPERATIVE LEARNING:
Cooperative learning sessions will be scheduled: groups of 4 students will be made to work on a specific topic. The tasks of each group will be:
1) Elaborate an oral presentation: choose the fundamental parts of the work and expose it to the rest of the class.
2) Linked to the oral presentation, an infographic will be made together with a descriptive summary of the same.
The details of the work will be given during the presentation of the subject.
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
The evaluation of the course will be individual and continuous through tests that will assess:
-The individual learning of the student from partial exams.
-The cooperative learning from the formative activities programmed in the classroom practices, written and oral presentation of a pathogen following the competences of the subject.
The evaluation activities programmed in the subject of Immunology are:
Midterm (partial) exams: two midterm exams. Each test will count 35% of the final grade (70% of the final grade between both midterm exams). They will be multiple-choice exams of at least 30 questions with 5 options and only one correct one. In the correction, 1/5 of the value of each question will be subtracted for an incorrect answer. To pass this part of the course, the average grade of the two midterm exams must be equal or higher than 5. Students must achieve a minimum grade of 4 in the midterm exams in order to average them.
Cooperative learning: It is proposed as cooperative work in groups of 4 students. The objective is that students develop their self-learning skills, search and selection of information and finally develop the ability to synthesize and written communication. The ability to work in groups is also valued.
The evaluation of cooperative learning will represent 30% of the final grade of the course. For the grade of the group work, the content of the work, format, oral presentation and subsequent discussion will be evaluated.
In order to pass this part of the course, the grade for the cooperative learning will be equal or higher than 5.
The final grade of the subject will be composed by the score obtained from the two partial (70% of the grade) plus the score of the cooperative learning work (30% of the grade).
REMARKS:
-In case of not passing any of the midterm exams or if the student wants to raise the grade, he/she will have the option of taking a final exam that is composed by midterm exams (i.e. the student has the option of taking only one of the midterms or both, as appropriate). The format of the make-up exam may be multiple-choice and/or short questions. The format of the make-up exam will be announced in advance.
- Students who wish to raise their grade lose their previous grade.
-Failure to attend any of the tests must be justified in order to be able to repeat them.
-To participate in the recovery, students must have been previously evaluated in a set of activities whose weight is equivalent to a minimum of two thirds of the total grade of the subject. 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:
Students have the possibility to apply for the single evaluation. The single evaluation consists of the following:
-Students waive to take the two partial exams separately and will take a single exam (single evaluation exam) on the same date as the second partial exam is taken. This exam will have the content of the whole course and will account for 70% of the final grade. In order to pass this part of the course, the grade of the single evaluation exam must be equal or higher than a 5. The format of the single evaluation exam will be informed in advance.
-RECOVERY: The same recovery system will be applied as for the continuous evaluation.
-Students who opt for the single evaluation must also take the cooperative learning part (30% of the final grade) and will have to attend the classroom practices (which are compulsory for all students).
