| Methodologies |
| Methodologies | Description |
| Guest lecture / keynote speech | Oral presentation complemented by the use of audiovisual media and the introduction of some questions addressed to the students, with the purpose of transmitting knowledge and facilitating learning. |
| Supervised projects | Methodology designed to promote autonomous learning of students, under the guidance of the teacher and in varied scenarios |
| Laboratory practice | Methodology that allows students to learn effectively through practical activities You cannot pass the subject without attending the laboratory practices. |
| Mixed objective/subjective test | Integrates objective test type questions that combine multiple response questions |

| Laboratory practice | A23 B2 B7 C1 C4 C5 | Completion with the use of laboratory practices is essential to pass the subject. The laboratory practice exam will represent 1% of the final grade for the subject, as long as the student obtains 4.5 points. out of 10 in the objective test, in no case can it serve to compensate grades lower than 4.5 pts, in the Mixed Test. |

| Mixed objective/subjective test | A23 B2 B7 C1 C4 C5 | The mixed test that will be carried out at the end of the course, in the corresponding official calls, where the student must demonstrate their degree of learning in an objective way. They will consist of two parts with a number between 10 and 15 multiple choice questions in each of the parts, accompanied by 6 possible answers, where only one is correct, the student must always justify the answer, this being an essential condition for the answer is accepted as correct. Incorrect answers will deduct 0.17 points. To pass the subject the student must obtain 4.5 points. out of 10, at least in each of the two parts of this test. |

| Supervised projects | A23 | These are practical cases proposed by the teacher, which must be resolved and explained through an oral presentation. | 30 |
| Assessment comments | |||
|
-The subject is divided into 2 parts, at the end of the presentation of the 1st part coinciding with the middle of the school period, a voluntary test will be carried out, which will be eliminatory, the students who pass it will no longer have to take the same exam again in the calls for the 1st and 2nd opportunity of the course where they passed the 1st part. - The evaluation criteria will be the same for the 1st and 2nd opportunity and similar tests. -Class attendance is recommended, being mandatory in laboratory practices. - The fraudulent performance of tests or evaluation activities, once proven, will directly imply a failure grade in the call in which it is committed: the student will be graded with “fail” (numerical grade 0) in the corresponding call of the academic year, whether the commission of the offense occurs on the first opportunity or on the second. For this, your qualification will be modified in the first opportunity report, if necessary. |
