The subject of Microbiology consists of three modules, which have been programmed in an integrated way to reach the competencies indicated in section 5 of this guide.
The modules are as follows:
1. Participatory classroom lectures: Lectures will address the main ideas of the different topics. Students should expand and confront autonomously as a personal work. At the beginning of the course the content of the different topics will be explained by the professor, as well as the bibliography that should be consulted to prepare each theory lecture and for personal study of the topics explained. Each topic taught will be based on a theoretical presentation and a brief discussion. Some topics can be prepared by students, guided or autonomously, and then discussed in the lecture sessions through questions (flipped classroom).
2. Scientific problem seminars: These seminars are sessions with the mission of: a) working methodological aspects, b) training the student to design basic microbiology experiments and to propose experimental approaches, c) designing strategies for solving and interpreting scientific problems, d) acquiring the skills necessary to perform literature research, text reading and oral presentations, e) to facilitate the understanding of the knowledge presented in the theory lectures and f) to bridge the gap between theory lectures and laboratory practices, with the objective of integrating the theoretical and the practical knowledge. The student will receive proposals for problems and/or scientific cases that will be developed during the course in class both individually and in a group.
3. Active learning activities: These activities are sessions with the mission of: a) facilitating the understanding of the knowledge presented in the theory lectures, b) acquiring the necessary skills to perform literature research, text reading and active self-study learning and c) encourage cooperative teamwork, coordination of activities and rational presentation of work plans and results. The student will perform oral, written and/or visual presentation of an issue, activity, gamification or scientific case. The professor will indicate the bibliography to be consulted and the relationship of each session with the topics discussed in the theory lectures.
Additional Information
In those sessions, students will have the opportunity to have individual guidance according to their needs. To follow adequately the course, the student will have access to all the materials used in the Campus Virtual.
As supervised activities of the subject, the students will be able to carry out tutorials in the teachers' office and / or through TICs. At the beginning of the course the procedure for conducting tutorials will be communicated.
The autonomous activities of this subject are: personal study, literature searching, reading of texts, preparation of different types of academic work/activities and resolution of problems.
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.
Title | Weighting | Hours | ECTS | Learning Outcomes |
---|---|---|---|---|
Evaluation public oral presentations of reports | 20 % | 2 | 0.08 | CM16, CM18, KM16, KM18, SM16, SM17 |
Evaluation scientific problems and seminars | 20% | 2 | 0.08 | CM16, CM18, KM16, KM18, SM16, SM17 |

Evaluation theory II | 30% | 2 | 0.08 | CM16, CM18, KM16, KM18, SM16, SM17 |
The evaluation of the course will be done individual and continued or single through the following tests:
I. Continuous evaluation
1. Evaluation of classroom lectures competencies
During the course two midterm exams, to evaluate the theory contents, will be scheduled. Each midterm exam to evaluate the theory contents will have a weight of 30% of the overall grade. The final mark of this evaluation form will be average of the two midterm exams. To pass this part of the subject, the notes obtained in each written tests must be equal to or greater than 5 points. If the average of the midterm exams is equal to or greater than 5 students will not have to do the final exam (or Remedial exam) of the subject. In the case of obtaining a lower mark of 5 in one or both midterm exams, students will be presented at the Final exam (or Remedial exam) on the date scheduled for the final evaluation of the course.
2. Evaluation of scientific problem and seminars
The evaluation of this activity will be done separately from evaluation of classroom lectures competencies considering the attendance at the seminars, the resolution of problems and practical cases or activities and the realization of a written exam at the end of the course. All of that will have a weight of 20% of the overall grade. Students who fail the evaluation of scientific problems and seminars can retrieve it on the date scheduled for the final exam of the course.
3. Evaluation of active learning activities
This activity is assessedseparately from evaluation of classroom lectures competencies and seminars and scientific problems evaluation considering oral presentations of the proposed activities and will have a weight of 20% of the final mark. Students will present the reports of the assigned active learning activitiesinclassroom sessions. Oral presentations will be evaluated oncontent, organization and communicative skills. Students who fail the evaluation of the group activities can retrieve the active learning activities onthe date scheduled for the final exam of the course.
To pass the course, students must obtain a mark of 5 or greater than 5 in each module.
Students who do not pass any of the written and/or oral tests may retrieve them at the scheduled date at the end of the semester. Likewise, on the same date, students who have passed the subject and want to improve their mark may submit to a global examination of the subject, which will include questions from the three evaluation modules. The presentation of the student to the examination of improvement of note implies the renunciation of the qualification obtained previously.
General questions:
- To participate in the recovery of the different assessment activities, students must have previously been assessed in a set of activities whose weight is equivalent to a minimum of two thirds of the total grade of the subject or module.
- Therefore, students will obtain the grade of "Not Assessable" when the assessment activities carried out have a weighting of less than 67% in the final grade.
- From the second registration for the subject, the student will not need to complete modules 2 and 3 if they achieved the competencies of this part of the subject in the previous year. This exemption will be maintained for a period of three additional registrations.
- Use of Artificial Intelligence (AI) technologies:
II. Unique assessment
The unique assessment consists of a single synthesis test in which the contents of the entire program of the subject will be evaluated. This will consist of three parts:
1. Evaluation of the theory module: It will consist of a summary test of all the contents of the theory module. The grade obtained in this test will account for 60% of the final grade for the subject.
2. Evaluation of the problems and techniques module:The same avaluation system will be applied as for the continuous assessment. Attendance at the seminars is mandatory. To pass the seminar part, a grade equal to or higher than 5 must be obtained, the grade obtainedin this part will be 20% of the final grade.
3. Evaluation of the active learning module: This last part will be assessed by delivering a report of the assigned active learning activities similar of those done in classroom sessions. The grade obtained in this part will be 20% of the final grade.
The grade obtained in this synthesis test is 100% of the final grade of the subject.
The single assessment test will coincide with the same date fixed in the calendar for the last continuous assessment test and the same recovery system will be applied as for the continuous assessment. To pass the subject, it will be necessary to pass each of the parts of the test separately with a score equal to or greater than 5 out of 10. In case of not passing the subject, the student will be able to opt for a recovery evaluation, with the same characteristics as the one described and where it will be necessary to obtain a grade equal to or greater than 5 in the parts that had not been achieved on the firstattempt to pass the subject. The review of the final grade follows the same procedure as for continuous assessment.
