4. COURSE DESCRIPTION AND TEACHING METHODOLOGY

LECTURES

During the lectures, the different sections included in the course's syllabus will be developed. Student participation may take place at any time and doubts will be solved at the time. During lectures the problems of the course included in the collections of problems will be solved in a participatory way and discussion of results and resolution methods will be exposed. Selected exercises and practical cases will be solved at the end of each chapter, along with some exams problems. 

To complement the learning process, the student will have at hand notes and slides with some of the content of classes. Additionally, collections of problems and previous exams will be also available. 

LAB SESSIONS

Practices will be held in the laboratory of the area of mechanics of continuous media and theory of structures. Lab session will be divided in two parts: first, there will be a theoretical introduction along with some exhibition, where the teacher will explain the tasks to be performed using lab equipment; then, student must work on their own and collect data to ellaborate a final report, to be submitted after a few days.

Notes concerning the lab sessions will be available beforehand at the web site of the course. The content of such notes is considered selfcontained, and will allow the student to learn about the theoretical aspects and practical exercises and equipment before going to the lab. 

OTHER INFORMATION

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support.

5. ASSESSMENT METHODOLOGY

At the final exam, the score of both theoretical and operating contents of course must be greater than zero in each of part, to pass the exam. 

In particular, the theoretical contents' weigth in the final exam is 30%, while the remaining 70% concerns operational exercices (problems) 

Additionally, the student is required to pass independently both final exam and lab sessions, in order to pass the course. The learning process associated to the lab sessions will be evaluated by means of a virtual test at the end of the semester, which will ask about content and practical tasks performed by the student at the practices. Additionally, the student will have to turn it the files containing calculations and notes from the lab sessions.
