Assessment comments
The evaluation criteria contemplated in tables A-III / 1 and A-III / 3 of the STCW Code and included in the Quality Assurance System will be taken into account when designing and carrying out the evaluation. Students with recognition of part-time dedication and academic exemption from attendance exemption will not be required to have a minimum attendance to be able to take the partial exams, however, a series of tutorials (face-to-face or non-face-to-face) must be agreed with the teacher. throughout the course to accredit the follow-up of the matter.

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.
