The acquisition of knowledge will be carried out through the use of theoretical classes, problem classes, laboratory practices and presentation of scientific articles
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.
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.

Continuous Assessment
Written tests (60% of the grade). According to the academic calendar, two tests will be held. Each of these exams will have a weight of 30% of the final grade. If the average grade of these two exams is less than 5, a final exam must be taken at the end of the semester that will include the contents of the entire course, and whose grade will be equivalent to 60% of the total. In order to take the final exam, students must have participated in assessment activities throughout the course that are equivalent to 2/3 of the grade of the subject. Otherwise, the grade will be "Not presented".
Continuous work (10% of the grade): Evidence from the student will be collected throughout the course (problems solved, individually or in groups, short tests in class, etc.). These activities cannot be recovered unless the student provides a greater justification with the corresponding official documentation. This activity will have a weight of.
Oral presentation on a scientific article (15% of the grade): Each student or group of students will be assigned a scientific article related to the contents of the subject. Students must make an oral presentation on this article. Each student will be awarded a grade based on the presentation made and their answers to the questions asked. This grade will have a weight of 15% on the final grade of the subject. Carrying out group work (15% of the grade). The completion of this work is mandatory and cannot be recovered.
Laboratory practices (15% of the grade). Attendance at the laboratory sessions is mandatory, as well as the delivery of reports if the professor requires it. The lab grade will be graded between 0 and 10.
Single assessment
Single assessment: Students who have taken advantage of the single assessment modality must take a final test that will consist of the following activities:
- Written theory test: A single written exam will be held at the end of the academic year in which the theoretical continuums of the subject will be evaluated, which will have a weight of 70%. If the mark of these exams is less than 5, a final retake exam must be taken. In order to take the retake exam, students must have participated in the final single assessment test. Otherwise, the grade will be "Not presented".
- Laboratory practices (15% of the grade). Attendance at the laboratory sessions is mandatory, as well as the delivery of reports if the professor requires it. The lab grade will be graded between 0 and 10.
- Oral presentation on a scientific article: Students will make an oral presentation on an assigned scientific article. The presentation and the answer to the questions asked will be evaluated with a grade, which will have a weight of 15% of the final grade of the subject.
Regardless of the evaluation modality chosen, in order to pass the subject, students must have:
1) A mark of theoretical exams higher than 5.
2) An average grade of the subject higher than 5.
3) Have attended the practice sessions in the laboratory. Laboratory Safety Warning: Students who are involved in an incident that may have serious safety awareness may be expelled from the laboratory and fail the subject.
