Methodologies
Methodologies Description
Guest lecture / keynote speech These classes constitute the main body of teaching practice and be dedicated to both the exposure of theoretical issues strictly related to the subject, and the resolution of exercises and class issues. The timing of the theoretical and practical classes will vary within the teaching schedule based on the requirements of each subject, and will in any case forward students for your convenience.
As for the lectures, they will be exposed as clearly and concretely as possible. During his presentation, it will be addressed in particular to the level of knowledge that the student has at the time of exposing the various individual agenda to complete if some aspect which, although not strictly subject of the document may constitute a gap in knowledge of the student body.

I consider very important in any of the classes taught, the fact that classes begin and end on time, which helps to strengthen the relationship of respect with the students. We also try as far as possible to expose the issues in a relaxed, friendly tone. In return, it requested by students a positive, caring and active attitude. Pupils regularly insist on the possibility of existence of doubt.
All the exhibitions will be held on the board, except in some very specific question, as the explanation of programming codes of some length, in which case the projection of transparencies will be used. During exhibitions on the board will take care of clarity and size of writing, and colored chalk, especially when graphics are reproduced be used.
Seminar

It has been called seminar classes in practices which aims at solving the problem sheets.

Throughout the development of the course students Problem nine sheets will be provided as part of the teaching material for the course. Such sheets are also published on the website of the subject. The title of each of these sheets Practices and Problems is:

Sheet 1. ODEs resolved in the derivative
Sheet 2. EDOs derived unresolved. Curves and Paths
3. Differential Equations sheet of more than 1 order
Sheet 5. Differential Equations Systems
6. Laplace Transform Sheet
7. Powers Sheet Series
Sheet 8. Orthogonal Functions and Boundary Problems
Sheet 9. Fourier Series

Sheets Practices are a collection of problems of the course containing problems with the degree of difficulty of those proposed in exams. The exercises are these leaves are solved during the practical classes.
Each of the sheets Problems consist of five exercises level exam, for which a deadline is proposed and that after correction are returned to students. Conducting Problems Sheets is part of the evaluation of the subject.
Within Sheets practices and problems a number of exercises for applying differential equations solving different engineering problems is included.
As in the case of lectures, this exhibition will take place on the board. Pupils are provided a time for them to silvering the problem before its resolution on the board. It will emphasize the need to ask all the questions raised during these classes.

Mixed objective/subjective test Completion of a written examination with books and notes which will be constituted by a total of five problems.
