TEACHING METHODOLOGY

lessons. They consist of the exposition by the professor of the contents of the subject. Competences: COP23, COP24, CG4, CG5, CG6, CG9, Cg11, CB6, CB7, CB8, CB9, CB10, CT3, CT5, CT6, CT10, CT11, CT12, CT14, CT15.
We will work with specialized scientific and informative articles, as well as specialized pages in English, elaboration of flow diagrams and explanation of the process based on videos and Glossary in the official languages ​​and in English for the elaboration of individual works.

Autonomous and cooperative learning will be encouraged. The use of AI tools will be encouraged.
The different activities will be evaluated continuously by scoring on the Moodle platform tools (Homework Submission, Forum, Questionnaire and others).

- Interactive teaching of Seminars, Laboratory and field trips. Competences: COP23, COP24, CG4, CG5, CG6, CG9, Cg11, CB6, CB7, CB8, CB9, CB10, CT3, CT5 , CT6, CT10, CT11, CT12, CT14, CT15.

- Tutorials: resolution of doubts (1 hour).

TUTORIALS OF ATTENTION TO THE STUDENT. They are tutorials that are not reflected in the calendar, which will be carried out throughout the course to answer questions from students. To carry out tutorials, as well as to maintain direct communication both between the students themselves and between them and the teacher, you can use the Virtual Campus forum, MS Teams or email.



For the realization of tutorials, as well as to maintain direct communication both between the students themselves and between them and the teacher, the Virtual Campus forum, Ms. Teams or email can be used.

EVALUATION:

The skills acquired (COP23, COP24, CG4, CG5, CG6, CG9, CG11, CB6, CB7, CB8, CB9, CB10, CT3, CT5, CT6, CT10, CT11, CT12, CT14, CT15) will be evaluated based on:

Evaluation system.

The qualification of each Part (Technology and Microbiology) will be divided into:
- Continuous evaluation: 50%
- Presentation of works: 50%

Therefore, the student's evaluation will include a continuous evaluation that will involve 50% and presentation and defense of work, which will involve 50%.

The grade will be weighted as follows:

- 50% of the final mark (Technology Part) through the marks obtained by the students in forums with scores, homework, work with videos ...; and other e-learning tools on the Moodle platform, and the Presentation of works.
- 50% of the final grade (Microbiology Part)
The final grade will be the sum of the two parts

Evaluation criteria for students who do not pass the course. If the minimum passing grade is not reached, the subject is suspended, the student will take a final exam based on the material from the Moodle Virtual Classroom.

June exams. The final test (delivery of works) will suppose up to 50% of the note that will be added to the continuous evaluation.

July exam. The final test (delivery of works) will suppose up to 50% of the note that will be added to the continuous evaluation.

Students who repeat. Repeating students from previous years will be exempt from complying with the duty to attend classes. To pass the course, it is mandatory to carry out and deliver the proposed activities on the same dates established for the rest of the students.

Contingency plan
"In cases of fraudulent performance of exercises or tests, the provisions of the" Regulations for evaluating student academic performance and reviewing grades will apply.

The evaluation system will be exactly the same regardless of the type of teaching used (face-to-face or virtual), with the only difference that the evaluation activities will be carried out, as established by the competent authorities, either face-to-face in the classroom or remotely through the telematic means available at the USC.
The evaluation criteria will be the same for those who take the final exam at the first and second opportunity.
The evaluation criteria for the repeaters will be the same as for the other students.
The students who have an attendance waiver will be able to do the same work as the others in terms of all the work and evaluations carried out through the Moodle platform.

The total hours of the subject are divided equally between PART 1 (FOOD TECHNOLOGY) and PART 2 (MICROBIOLOGY)

Lectures: in class: 12; hours autonomous work: 10
Group : in class: 4; hours autonomous work: 4
Practicals: in class: 6; hours autonomous work: 4
