Methodologies   ::  
  Description
Problem solving, classroom exercises Formulation, analysis, resolution, and discussion of a problem or exercise related to the subject matter. The aim is for the student to understand the theoretical content covered in the lectures.
Personal tuition It will be dedicated to solving specific doubts about issues that students may have.
Laboratory practicals They will be developed in a Department Laboratory. Groups will be created with a very small number of students to carry out a practical work assigned to each group, consisting of carrying out the practices indicated, as well as preparing the corresponding practice report. Students will have the necessary documentation and material available to carry out the practices. In this way, with the clarifications made in a timely manner by the professor, the student will be able to carry out the practical work. Students will take note of the results and prepare a report that must contain the theoretical basis, the practical implementation, the results obtained, and the specific conclusions of their work. The student will submit, within a period of less than 2 weeks after each practice, a report that will serve as the evaluation criteria for the practical part.
Lecture First, a theoretical exposition of all the concepts included in the program is presented. Then, the concepts are justified and their application to specific cases is shown.

Assessment
  Description Qualification
Lecture The student's participation in class and in the debates that take place in the classroom will be evaluated. Regular attendance to classes and the attitude shown may be taken into account for the evaluation. It is evaluated jointly with the section of mixed tests. 0%
Laboratory practicals Evaluation of internship work. The skills acquired by the student in the practical application of knowledge will be assessed. All scheduled internships must be completed, and all required assignments and reports must be submitted in order to pass the course.

Attendance at internship sessions is mandatory to pass the course. Only those internships for which non-attendance is properly justified (a certificate must be provided) can be made up.

The evaluation of internships will be carried out once the minimum established in the tests and exams of the subject has been passed.

Submission is mandatory and obtaining a score of 5.0 out of 10.0 on the test is a requirement. No average will be calculated if this condition is not met.

The total weight of the practical part will be 20%.

The internship report will be submitted in PDF format through Moodle (adhering to the maximum size allowed by the platform). Submission deadlines will be set throughout the course.
20%
Mixed tests The grade obtained in the corresponding controls throughout the training process.
They will be designed to evaluate the competences acquired by the student. The regular attendance to the classes and the attitude shown may be taken into account for the evaluation. To pass the course it will be necessary to pass each of the blocks in which the content is divided.
The student's participation in theory and problem classes will also be taken into account.
75%
Others Delivery and/or presentation of problems proposed by the teacher. 5%
 
Other comments and second call

It will be mandatory to obtain a grade of 5.0 out of 10.0 on any test. No averaging with other parts will be done if this condition is not met.

No assignment or test will have a recovery option.

DOCUMENT SUBMISSION, EXAMS, ASSIGNMENTS, ETC.

Any document submitted will be either through the Moodle platform (PDF format, no other format will be accepted) or in paper format, or both. Email submissions are not allowed. Late submissions are not permitted.

The filename will be the student's ID number plus first name and last name plus an identification of the problem or test. Example: 10.123.456F_JoseMartinezPerez_Problem7.pdf.

Every document must internally contain the student's name and ID number, as well as the contents with the solution to the problem, question, etc. Any assignment submitted must contain at least the following:

Introduction or statement.
Objectives.
Solution or practical execution.
Analysis of the solution.
Conclusions and personal assessment.
ATTENDANCE TO INDIVIDUAL TESTS and REVIEWS

The student will come equipped with valid identification.

The level of the tests will be equal to or higher than what has been covered in the classroom so that those brightest students can achieve outstanding grades.

The exam may be video-recorded, and any actions can be subsequently reviewed for fraud or cheating.

If a student is found to have cheated, they will be suspended for 2 sessions according to the current regulations of the ULE or disciplinary action will be taken if necessary.

The student will attend the exam or test after having read the regulations regarding the examination rules approved by the Governing Council of the University of León, which will be rigorously applied.

The student will enter the exam room with only:

Blue or black pens,
One correction fluid (whiteout or similar) and a ruler,
One non-programmable calculator,
In case additional materials are allowed for the exam, they will be in a folder containing only printed materials on paper.
Water may exceptionally be brought in a transparent bottle without stickers or additional markings. During the test, the student may use it exceptionally, keeping it away from the workspace at all times.

Any other materials such as pencil cases, staplers, backpacks, etc., except for outerwear, will be left outside the exam room. Outerwear will be placed on designated racks, and all desks and chairs in the exam room will be left clear.

It is expressly forbidden to bring any electronic devices into the exam room: phone, tablet, or similar.

It is expressly forbidden to talk to another student or request any type of material once you have entered the exam room.

The use of writing instruments other than black or blue is expressly prohibited, as well as the use of pens and mechanical pencils. Any notation in red will be considered part of the teacher's notes during the correction or explanation phase.

Students are not allowed to leave the exam room while any student is completing an exercise in the exam or test.

It is strictly prohibited to bring any food or drink into the exam room except for water.

The problems will include the value of each question along with the statement, and each result will be highlighted by the student with a box along with its units. An item of the problem will be considered correct if the solution does not differ by more than 10% in excess or defect from the exact solution, the units are correct, and the procedure followed by the student leads to the calculation noted in the indicated box. There will be no intermediate evaluations in each section that has independent scoring.

Each section of a theoretical or practical question will start on a separate sheet of paper clearly indicating the question that begins in reference to the exam statement.

Exam papers with erasures, smudges, etc., will not be corrected; however, students are allowed to use spelling correction fluid.

Exam papers that do not include all student data: ID, name, and 2 last names will not be corrected.

More than 5 spelling mistakes will allow the teacher to stop correcting the exam, as some of the competencies listed in this teaching guide are not met.

Any test in the subject may be oral or written, and there is no need to notify in advance. Any test that must be conducted outside of the established dates and times due to compliance with higher-level legal provisions will always be oral in the presence of three or more department members.

Submitting the exam after the final declared time during the execution gives the right to not correct the exam. Exams submitted within the agreed-upon time and those submitted afterwards will be separated.

The review of any test or exam will be governed by the regulations of the University of León's examination regulations. The review will be done in writing, for which the student will come equipped with the material they consider necessary to check the exam results, as well as a red pen. No other pen can be used during the exam review. The student will be provided with a form to transfer any claims they have. Personal connotations unrelated to the course will be avoided.

Once the review is completed, the student's claims regarding the correction will be analyzed. If necessary, the grade will be adjusted, and a revised grade report will be issued. The exam review may result in both an increase or decrease in the grade of any test. If errors that were overlooked in the initial correction are detected, the grade may be lowered. This criterion may cause a student who was initially approved to fail.

Regular attendance in classes and the attitude (attention, participation, collaboration, etc.) shown may be taken into account for the evaluation of each of the blocks. In this case, the teacher will inform about the criteria to be used. To pass the subject, it will be necessary to pass each of the blocks into which the content is divided. If one or more blocks are not passed, the average grade of those blocks will be transferred as the overall grade of the subject. If all blocks are passed, the subject grade will be obtained from the weighted average (based on the credits assigned to each block).

SECOND SESSION:

Theory evaluation: One or more written tests will be carried out with the program contents. The grade obtained will account for 80% of the total subject grade.

Practice evaluation: The student's grade obtained in the laboratory practices will be retained, or if preferred or if they have failed, they must pass an alternative exam to pass the subject. If the student opts for this option, they must inform the responsible professor at least one week before the start of the evaluation and review period of the second session. The grade obtained will account for 20% of the total subject grade.
