Teaching will consist of the following training activities:
- Lectures: lectures given by the lecturer with the support of various computer materials. Students will have access to complementary material in the virtual classroom for the study and preparation of the subject.
- Practical laboratory classes: these include classes that take place in the practical laboratory. The completion of the practicals is compulsory and essential to pass the subject and once completed they will be valid in the two academic years following the one in which they were taken.
- Tutorials: These will be scheduled by the teacher at the request of the students. Activities such as clarification of doubts about theory, practices or readings are proposed.
The two parts of the subject, Microbiological Analysis, which will represent 60% of the final mark, and Parasitological Analysis, which will represent 40% of the final mark, will be assessed independently, according to the following criteria:
- Microbiological Analysis: Assessment will be based on continuous assessment and a specific final test. The student's mark for this part of the subject will result from the assessment of the following sections:
1) Compulsory final specific test (face-to-face) based on objective questions and practical cases. In this test, the knowledge acquired in the practical laboratory classes will also be assessed: 75%.
2) Continuous assessment: 3 questionnaires to be carried out throughout the course in the classroom or through the virtual classroom or the MS Teams platform: 25%.
- Parasitological Analysis: The evaluation of this part of the subject will be based on a specific final test (face-to-face) consisting of objective questions and practical cases. The knowledge acquired in the practical laboratory classes will also be assessed in this test: 100%.
The assessment of the competences and skills acquired will be carried out:
In the exam: Con 22, Con32, Con 39, Comp 03
In the laboratory. Con 03, Comp 01, Comp 02; Comp 10, Comp 17, Comp 27, H/D02, H/D04
In order to pass the course, it will be necessary to achieve a minimum score of 50% in each of the parts of the specific final exam. If this minimum is not reached in any of the parts, the grade that will appear in the report will be that of the part not passed. If only one part of the subject is passed, the mark obtained in that part will only be retained in the same academic year.
If the student does not take the final exam in either of the two opportunities, he/she will be graded as ‘No-show’.
The student will not be able to pass the course if he/she does not take the laboratory practicals. In this case, their final mark for the course will be ‘No Show’.
In the case of students who are excused from class attendance, the evaluation will be based solely on the final exam and the completion of the practical classes (100% of the final grade).
In the 2nd opportunity of the academic year, the same evaluation criteria will be followed.
- For cases of fraudulent completion of exercises or tests, the provisions of the Regulations for the evaluation of the academic performance of students and the review of grades will be applied.
• Individual or group independent study: 65 hours
• Taking tests as part of the continuous assessment: 1h
• Realization of practices: 24h
• Total hours of personal work of the student: 90h
It is recommended to keep up to date with the subject in order to get the most out of it, to attend lectures, to attend regularly, not to progress without understanding and knowing the previous subject, to use the virtual platform as a complement, to consult the bibliography, to use the tutorial hours to resolve any doubts and to read the practical syllabus before going to do them.
