Description |
Introductory activities |
There will be a presentation of the course, emphasizing the importance of this matter as a basis for learning other subjects in the Degree and for professional activities in the field of Marine Engineering.
The standards of teaching, qualification and most important bibliographical sources will be set. |
Guest lecture / keynote speech |
There will be a detailed explanation of the contents of the material, distributed across topics. The student will have a typed copy of the subject matter in each keynote session. Students are encouraged to participate in class, through comments linking the theoretical with real life experiences.
|
Problem solving |
Problems will be solved for each item proposed, allowing the application of mathematical models appropriate to each case, including managing tables, applying the most appropriate assumptions, the theoretical relation developed in lectures and relation with professional practice
|
Collaborative learning |
Problem solving in groups, with the possibility of exposing results. |
Supervised projects |
Problems more difficult than those solved in class or issues of special relevance.
|
Document analysis |
By means using bibliographical sources of different types, the student will get used to finding information in order to deepen or focus learning from other points of view that are not exclusively those from the professor. It is like a training to the future needs of students in their professional development.
|
Objective test |
There will be a midterm exam so that students become familiar with the type of issues raised in the written tests. It will consist of a theoretical and practical part, so that both computed for 50% of the grade. Regular and special examinations shall be governed by the same format. |
