Learning activities and methodology

Title Hours ECTS Learning outcomes
Excersise sessions 3 0.12 7, 8, 10
Practical sessions of Microbiology and Parasitology (25h), Chemistry (44h) and Animal, Plant and Cell Biology (25h) 94 3.76 1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 16, 18

The teaching methodology will be based on learning through the active student work. The teacher will help the students in this active learning process and will give access to the information and superve their work. In agreement with the formative objectives of the subject and of each of the parts that integrate it, the formative activities are laboratory practical sessions. In the case of the Chemistry part, seminars are held prior to the practice sessions to optimize their development. The students perform the experimental work individually or in groups of two under the supervision of a teacher. Before each practical session, the students must have read the practice the practice guide in order to know the objectives of the session, its basis and the procedures the protocol that must be developed. The objective of the practical lessons is to complete and reinforce the knowledge acquired in the theoretical lessons and seminars of the corresponding subjects. In the practical sessions students will be stimulated to acquire some skills such as the ability to observe and to analyse and interpretate the results obtained. At the beginning of each session there will be an introductory explanation of the theoretical basis of the practical lesson, its interest in Food Science and Technology, how the devices that will be used during the practice work and what are the general safety rules for its development. At the end of each practice the students will be assessed through a test exam (in some cases, the students will find the questions in the guide of the practical lesson).


The teaching material used in the course will be available on the Virtual Campus platform (Moodle). At the beginning of the course the student will have available a guide of all the practical lessons to be carried out in the laboratory. In each lesson theobjective/s, basis and methodology will be defined, as well as a section for the results that will be obtained and several questions that need to be answered in each session. This platform will also be used as a mechanism for exchanging information and documents between teachers and students. It is important to note that attendance to all practical sessions is compulsory and that absences must be duly justified. In some cases, the student will also find self-assessment material in the Moodle, which can be used to reinforce the process of knowledge acquisition.


Regarding the Microbiology and Parasitology and the Chemistry sections, in the first session the student must provide the teacher with a signed form (attached to the script) stating that the student knows the rules to work safely in the laboratory and commits itself to comply with these rules . To achieve good performance of these sessions it is necessary that the student has made a prior comprehensive reading of the content of each of the practices.

**The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.


Use of artificial intelligence:

Restricted use: For this course, the use of Artificial Intelligence (AI) technologies is permitted exclusively in study support tasks, bibliographic or information searches, text correction or translations. In the event that artificial intelligence is used in any deliverable document, the student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. The lack of transparency of the use of AI in this assessable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.

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

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Microbiology and Parasitology questionnaires 25% 2 0.08 1, 2, 4, 5, 14, 15, 18
Questionnaires, tests and theoretical exam of chemistry 50% 4 0.16 1, 2, 3, 4, 6, 7, 8, 9, 10, 11
Questionnaires and Biology tests 25% 4 0.16 1, 2, 4, 12, 13, 16, 17

Assessment

The students will be individually assessed after each training activity . To pass the course, a minimum score of 45% must be reached on the maximum score in each of the parts. Each part has a certain weight in the global mark of the subject that is specified below.


- Chemistry (weight of 50% in the final grade of the subject): Continuous assessment during the practical sessions in which a report should be submitted at the end of each session. At the end of all the sessions, a test exam will be done and the laboratory notebooks will have to be presented. The final grade of the chemistry module will be obtained as follows:

Internship report: 85%

Attitude in the laboratory: 10%

Notebooks: 5%


- Biology (weight of 25% in the final grade of the subject): Continuous evaluation throughout all the practices. After each practice a written test a questionnaire or a test type exam will be done.


-Part Microbiology and Parasitology (weight of 25% in the final grade of the subject): The Microbiology laboratories represent 60% of the module grade and the Parasitology practices represent the remaining 40%. To pass the module, it is necessary to obtain a minimum grade of 5 in each part. The assessment is continuous during the practical sessions in which some questionnaires must be solved. The attitude and participation in the module sessions throughout the learning process can allow obtaining up to 5% of the final grade for this module.

To pass the subject, attendance at practices is mandatory.

The final assessment of the subject will be obtained from the weighted average of the assessment of the different contents of each of the parts. To pass the subject it is necessary to obtain a final score equal to or greater than 5 out of a total of 10 points.

Students will beconsidered not assessable if they have participated in evaluation activities that represent ≤ 15% of the final score

This subject does not contemplate the single assessment system


**Student’s assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.


Academic fraud:

The commission of any irregularity in an evaluation activity (academic fraud, plagiarism or improper use of AI, unless this use is expressly authorized in the teaching guide), which may lead to a significant variation in the grade, means that this act will be graded with a 0. In the event that the teaching guide provides that to pass the course it is an essential requirement to have obtained a minimum grade in this assessment act or that several irregularities occur in the assessment acts of the same subject, the final grade for this subject is 0. Apart from this, a disciplinary process may be initiated against the student who incurs any of these irregularities.
