Visit to an electrochemical industry
Methodology
The acquisition of knowledge will be carried out through the use of theoretical classes, problem classes and laboratory practices.
Theoretical classes (on the board with the help of audiovisual media) in which the basic concepts will be introduced to be able to understand the fundamental and applied aspects of Electrochemistry.
Problem classes (with more student participation) in which the methodology will be indicated to quantitatively solve numerical questions
Laboratory practices (which will be carried out according to economic availability) in which the knowledge acquired during the theoretical classes and of problems to the habitual electrochemical manipulation will be applied. The purpose is twofold, to affirm the fundamental concepts and acquire the necessary experimental skills in Electrochemistry. The visit to an electrochemical industry will be made according to availability
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
The tests (60% of the grade). According to the academic calendar two tests will be carried out. A grade equal to or higher than 4.0 (out of 10) is required in the tests so that the remaining 40% of points can be added (classroom work and laboratory practices). In the event that the grade is lower than 4.0, the student will have to take the recovery exam, which will include all the material, to pass the subject. In addition, to participate in the recovery the students must have been evaluated in a set of activities whose weight equals a minimum of two thirds of the total grade of the subject.
Realization of classroom work (20% of the grade). The completion of this work is mandatory and is not recoverable.
Laboratory work (20% of the grade). Attendance at laboratory sessions is mandatory and is not recoverable.
Unique assessment
Laboratory:
Laboratory work (TL) (20% of the grade). Attendance at laboratory sessions is mandatory, as well as handing in reports if required by the teacher. The TL grade will be graded between 0 and 10.
Exams:
A final test (PF), which will consist of an examination of the entire syllabus of the subject. This will take place on the day that the students of the continuous assessment take the second part. The Final Test (PF) will be graded between 0 and 10.
Qualifications:
The final grade of the student who opts for continuous assessment, before and after the recovery, will be calculated according to:
NF = 0.20 TL + 0.8 PF.
To pass the subject per course, you must obtain an NF greater than or equal to 5.0.
Students who do not pass the subject by year:
If the NF does not reach 5, the student has another chance to pass the subject by means of the make-up exam.
The student's new qualification will replace the PF of the previous formula. The TL grade cannot be recovered.
To pass the subject with recovery, the student must meet the same requirements as to pass the subject by course.
If it is detected copying a student will be urged to leave the classroom with the consequence of a failure in the subject.
During written tests, mobile phones or any communication system must be disconnected and stored in bags or backpacks. The use of these devices is strictly prohibited. In the case of detecting that a student contravenes these instructions will be expelled from the exam and / or test with the consequence of a failure in the subject.
Attention:
The student who is involved in an incident that may have serious consequences on safety may be expelled from the laboratory and suspend the subject
