Methodologies
Methodologies Description
Objective test Written tests will be carried out, consisting of theoretical and practical questions.
Case study Real case studies related to the processes object of the subject to study will be carried out. There will be a sharing of the studies carried out and the discussion of the different solutions adopted to the determined problem.
Problem solving They will propose and solve a series of problems referred to the contents of the subject matter, and oriented as far as possible to real cases.
Guest lecture / keynote speech The detailed explanation of the contents of the subject distributed in subjects will be made. The student will have bibliographical material of support of the subject in each master session. The participation of the student in class will be encouraged, through comments that bring to relate the eoric contents with the real experience.

Assessment comments

The evaluation criteria contemplated in table A-III / 2 of the STCW Code, and included in the quality assurance system, will be taken into account when designing and carrying out the evaluation.

The students with recognition of part-time dedication or academic exemption  "NORM THAT REGULATES THE RATE OF DEDICATION OF THE STUDY OF DEGREE STUDENTS AT THE UDC (Arts. 2.3; 3.b; 4.3 and 7.5 ) (04/05/2017):

Supervised projects account for  30 % of the total mark

Objective test accounts for 70 % of the total mark

*Evaluation observations:

The same requirements are maintained in the 2nd evaluation computing attendance both, personal and on-line if applicable (according to the attendee list downloaded from Teams).

For students with recognition of part-time dedication and academic exemption from attendance exemption, the grade obtained in the activities associated with the personalized tutoring system will correspond to the evaluation of the supervised projects methodology and objective tests, with a weighting of 30 and 70%, respectively
