Methodologies

Methodologies	Description
Supervised projects	They are proposed as a continuation of the workshop practices but with greater student autonomy in carrying out two works.
Problem solving	The exercises proposed for each topic will be resolved, allowing the application of the most appropriate mathematical models in each case in relation to the theoretical contents developed in the master sessions and also in relation to professional practice.
Workshop	In order for the student to consolidate the theory, the application works will be carried out in the workshop and laboratories in the specialties of conformation of surfaces with machining systems, welded joints and application of non-destructive tests in the verification of elements and systems.
Case study	In order for the student to consolidate the theory, case studies will be carried out in the workshop and in the classroom in the specialties of conformation of surfaces with machining systems, welded joints and application of non-destructive tests in the verification of elements and systems.
Objective test	Partial tests will be carried out in order for the student to become familiar with the type of questions that are raised in the written tests. It will consist of a theoretical part and a practical one, in such a way that both compute. Ordinary and extraordinary exams will be governed by the same format
Guest lecture / keynote speech	There will be a detailed explanation of the contents of the subject and that are distributed in topics. The student will have at all times the bibliographical material, of the subject to be dealt with in each master session. Participation in the classroom will be encouraged through comments that relate theoretical content to real life experiences.

Other comments

To help achieve a sustainable immediate environment and meet the objective of action number 5: "Healthy and environmentally and socially sustainable teaching and research" of the "Green Campus Action Plan":

a) The delivery of the documentary works carried out in this matter will preferably be requested in virtual format or computer support, and may be done through Moodle, in digital format, without the need to print them. In the case of being done on paper, plastics will not be used, the prints will be double-sided on recycled paper, and the printing of drafts will be avoided.

b) The full integration of students who, for physical, sensory, mental, socio-cultural or gender reasons, experience difficulties in gaining suitable, equal and beneficial access to university life will be facilitated.

c) The importance of ethical principles related to the values of sustainability in personal and professional behavior must be taken into account.

d) As stated in the different regulations applicable to university teaching, the gender perspective must be incorporated in this area (non-sexist language will be used, bibliography of authors of both sexes will be used, intervention in class of students will be encouraged ...)

e) Work will be done to identify and modify prejudices and sexist attitudes and influence the environment to modify them and promote values of respect and equality.

f) Situations of gender discrimination should be identified, and actions and measures proposed to correct them.
