The subject Environmental Biotechnology consists of three modules, which have been programmed in an integrated way, so the student will have to relate throughout the course the content and the activities programmed for that to achieve the skills indicated in this guide.

The three modules are as follows:

Master classes: Lectures or lectures represent the main activity to be carried out in the classroom and they allow basic concepts to be transmitted to students in a relatively short time. They will be complemented with Power Point type presentations and various didactic material that will be given to the students through the space Moodle.

Seminars: These are work sessions for groups with a small number of students, based on assignments proposed by the teaching staff, that students will work independently and that will be discussed or presented later in the classroom. This is a mandatory activity. In this activity, the use of AI is allowed but in a restricted manner. Therefore, for this subject, the use of Artificial Intelligence (AI) technologies is allowed exclusively in support tasks, such as bibliographic or information search, text correction or translations. 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 in 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.

Technical visits:Visits have been scheduled to waste treatment facilities of different types or to them to work on topics related to the subject in order to bring the student closer to real situations where the Environmental Biotechnologist can intervene. This is a mandatory activity.


Additional information

In order to support the training activities indicated above, students will be able to carry out tutorials individual sessions in the teaching staff's office, in which tutoring will have to be arranged beforehand. The student will have in the subject's Moodle space all the documentation provided by the teaching staff for to a good follow-up of the same. You can also consult the teaching space of the Degree Coordination for get updated information about the degree.

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

Assessment of the course will be individual and continuous through the following tests:

Theory assessment module (60% of the overall grade): Two written assessments for this module will be scheduled during the course. Each assessment must be passed independently. Each of the tests will account for 30% of the final course grade. The average of the two marks will only be calculated if a minimum grade of 4.5 out of 10 is obtained in each assessment. Otherwise, students must resit the failed component in the final examination.

Seminar assessment module (25% of the overall mark): The evaluation will include the following aspects: Oral presentation of the work done (15% of the overall mark). Taking written tests (10% of the overall mark). If the student has not participated in the preparation or defense of a seminar, the module is suspended.

Technical visits assessment module (15% of the final grade): At the end of visit, students will complete a short written quiz. The grade obtained on these quizzes will constitute the mark for this assessment component. Students who do not participate in the field trip will fail this module, and it cannot be retaken.


Final considerations

To pass the subject you must obtain a grade of 5 or higher in each module and have attended the field trips.

Students who do not pass any of the written tests will be able to recover them on the date scheduled for the final evaluation of the subject, as long as they have been evaluated in at least 2/3 of these It will be considered that a student will obtain the qualification of Not Assessable if he completes less than 67% of the assessment activities.

Students who wish to improve their grade will waive the previously obtained qualification, and will be examined of all the written tests corresponding to the different modules of the subject. Unique Assessment The single assessment consists of a single summary test in which the contents of the entire course will be assessed theory program of the subject. The grade obtained in this synthesis test will represent 60% of the final grade of the subject and must be equal to or greater than 5.

The single assessment will be done on the same day as the 2nd partial of the subject.

The seminar module assessment will follow the same process as the continuous assessment. The grade obtained it will account for 25% of the subject's final grade. The delivery of evidence from the seminars will follow the same procedure that to the continuous evaluation. The seminar module is compulsory, as is the field trip module. It is required to have approved the seminar module and having attended the field trips to be able to take the single assessment test. the note obtained in the seminar module, corresponds to 25% of the final grade and the field trip the remaining 15% and they must always be 5 or higher.


Use of Artificial Intelligence (AI):

For this course, the use of Artificial Intelligence (AI) technologies is permitted exclusively in support tasks, such as bibliographic or information searches, text correction or translations, and the resolution of complex mathematical systems in evaluable activities or in the resolution of class problems. 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 in the use of AI in this evaluable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the qualification of the activity, or greater sanctions in serious cases.

The commission of any irregularity in an assessment act (academic fraud, plagiarism or improper use of AI, unless this use is expressly authorized in this teaching guide), which may lead to a significant variation in the qualification, means that this act will be graded with a 0. In the event that the teaching guide provides that in order to pass the course it is an essential requirement to have obtained a minimum qualification in the evaluation or that several irregularities occur in the evaluation acts of the same course, 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.


Single Assessment

The single assessment consists of a single comprehensive examination covering the entire theoretical syllabus of the course. The grade obtained in this comprehensive examination will account for 60% of the final course grade and must be at least 5 out of 10. The single assessment will take place on the same day as the second midterm examination.

Assessment of the seminar module will follow the same procedure as in the continuous assessment system. The grade obtained will account for 25% of the final course grade. Submission of seminar assignments/evidence will follow the same procedure as in the continuous assessment system. Attendance at the seminar module, as well as at the field trips, is compulsory. Passing the seminar module and attending the field trips are prerequisites for taking the single assessment examination. The seminar module accounts for 25% of the final course grade, while the field trips account for the remaining 15%. In both cases, a minimum grade of 5 out of 10 is required.
