The contents connect with the Sustainable Development Goals (SDGs):

Goal 9: Industry, Innovation and Infrastructure.

Goal 11: Sustainable Cities and Communities

Goal 12: Responsible Consumption and Production

Goal 13: Climate Action

Large-group lectures: These will consist of lectures on the content of the programme for the whole group. The contents will be developed and discussed. Problems and exercises proposed by the teacher will be solved. This methodology and activities will allow students to acquire the indicated competences (CBB3, CC5, CG7) and the achievement of Learning Outcomes 07.

Small group classes: The practicals will be carried out in the laboratory where the student will receive a script with the objectives of each test and the procedure to follow for the development of the same. The student will have to take note of the necessary experimental data to carry out the corresponding calculations and to be able to make a correct practical report. Computer exercises will be carried out with specific software for Materials Selection. In addition, exercises will be solved, presentations will be given and other practical activities will be carried out. This methodology and activities will allow students to acquire the indicated competences (CBB3, CC5, CG7) and the achievement of Learning Outcomes 08.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

The final evaluation activity consists of a written exam at the end of the course, in
Which will evaluate the theoretical and practical knowledge of the different families of materials, as well as the knowledge acquired to relate their structure and properties.

The examination will consist of two parts: a theoretical part where the student will have to answer test questions or short questions related to the agenda developed in the subject; a practical part where the student will solve problems.

To evaluate laboratory practices, a practical exam will be conducted in which the student is confronted with the performance of one of the practices of the program presented in the laboratory.

The presentation of proposed problems, presentation and presentation of group work,
Self-assessment, contributions to the forum, or chats, all through the ILIAS virtual platform, as well as tutoring assistance. In addition, active participation in class, group work and discussions.

All this to evaluate the capacity CBB3, CC5 and CG7, as well as the learning result 7 and 8.

When calculating the final grade of the subject taking into account all the above aspects,
will have to have passed each of the parts separately, mainly the theoretical examination and the examination of practices.

Students who for work reasons, properly justified, cannot attend classes
get in touch with the teachers of the subject at the beginning of the semester.

In the case of changing to a multimodal scenario, the percentages will be identical to the face-to-face scenario.    In this case, the exam will be online and there will be a built-in data protection clause.    If the scenario were to move towards totally virtual teaching, both the evaluation and the weights would be the same as in the multimodal case.

Multimodal or mixed scenario in which a mixed, hybrid or multimodal model that combines face-to-face and non-face-to-face teaching (asynchronous and synchronous) is contemplated.   Depending on the number of students, it may occur that: a) There is a situation in which the number of students exceeds the capacity limited by the classroom.   In this case, the promotional activities are planned as follows:

b) There is a situation in which the number of students is below the capacity limited by the classroom.   In this case, the promotional activities are planned as follows:  

The means and resources used in this scenario will be those provided by the University of Jaén, as well as other types of resources such as electronic bibliographic resources that do not require the physical presence in the library.

The evaluation system of the multimodal system will be the same as in the face-to-face system.

The means and resources used in this scenario will be those provided by the University of Jaén, as well as other types of resources such as electronic bibliographic resources that do not require the physical presence in the library.

In this scenario, the evaluation will be online with the same percentages as in the face-to-face and multimodal scenarios.
