C1 CMECES1 That students have demonstrated possession and understanding of knowledge in an area of study that is based on general secondary education, and is usually found at a level that, although supported by advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study
C2 CMECES2 That students know how to apply their knowledge to their work or vocation in a professional manner and possess the skills that are usually demonstrated through the development and defense of arguments and the resolution of problems within their area of study.
C3 CMECES3 That students have the ability to gather and interpret relevant data (normally within their area of study) to make judgments that include reflection on relevant issues of a social, scientific or ethical nature.
C4 CMECES4 That students can transmit information, ideas, problems and solutions to both a specialised and non-specialised audience
C5 CMECES5 That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy

Methodologies
Methodologies   ::  
  Description
Problem solving, classroom exercises The professor will guide students in applying theoretical concepts and results to problem solving, encouraging critical thinking at all times. Exercises will be proposed and students will solve them, thus acquiring skills in using the necessary tools for problem solving.
Tutorship of group To guide students in their learning so that they become autonomous, competent and critical.
Lecture The theoretical foundations of the subject will be exposed, reasoned and deduced, and at the end of each section exercises and problems will be solved to clarify the theory explained.

Personalized attention
 
Tutorship of group
Description
In the group tutorials will be supervised mainly aspects related to the resolution of questions, problems and elaboration of the bibliographic work. The individual tutorials will be focused on the resolution of the doubts that arise to the student in all the activities included in the methodology.

Assessment
  Description Qualification
Mixed tests There will be three types of written tests:
1. Final exam of the whole course
2. 4 partial exams
3. Individual work and/or periodical controls to be carried out by the student. 		1: 70 %
2: 15%
3: 15 %
 
Other comments and second call

In order to pass the course, a minimum grade of 4 out of 10 points must be obtained on the first test, and the course is passed if the final grade is equal to or higher than 5 points.

In the second exam, the results of the tests taken during the semester are valid, although it is not obligatory to have taken them. In case of not having done the individual work, the grade of the final exam will be 80% of the evaluation.
