4. COURSE DESCRIPTION AND TEACHING METHODOLOGY

The lectures in large group will consist of lectures, theory and general examples, as well as introductory activities of the program content for the whole group in order to provide the student with a systematic overview of the different themes, highlighting the aspects more important of them, so that students clearly offered the possibility of motivation by experts in the field, through dialogue and exchange of ideas. Previous exposure of the objectives of each unit and its specific to the field of industrial engineering applications, provide a basis for focusing their interest and motivate learning. The subsequent development of each unit will be preceded by a general description of contents, illustrated through Microsoft Office PowerPoint presentations, of which students previously will have of in the ILIAS platform as well as the help of slate content that require it. On some issues, audiovisual sessions are used for a better understanding of the content. In these sessions the active participation of students will arise.

 

The practices academic sessions in the classroom are essential to strengthen and deepen the theoretical knowledge. They consist of the resolution of both Professor and student of problems concerning the topics covered in the lectures in large group. Besides discussions of those issues of greatest interest and relevance will be developed. On the other hand, experimental laboratory practices will be conducted in small groups (max. 20 students), which will be announced methodologies and relevant experimental techniques for the study of materials. Students will have a script beforehand with the documentation necessary for the implementation of practices. Practices consist of a brief theoretical explanation and then, explaining the operation of the instrument to be used. Later the student will to make this practice and preparing a report that will be evaluated.

Collective and individual tutoring: Where will be the supervision of targeted work, comments on individual jobs and clarification of doubts.

Several sessions will be held in the computer room in order to use the software CES EduPack for the use and selection of materials and fabrication processes.

To corroborate and / or supplement the results obtained in laboratory practices may be necessary to make analysis and / or testing in the Scientific and Technical Center of the University.

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

Written exam on the dates officially listed in the student guide. This objective test will be to respond to short answers and/or test type in which the most important aspects of the subject are discussed, in addition to problem solving (CT2, CB2, CB3, CC3, CC10) questions (38; 39; 40; 41; 42; 43; 44).

To assess the laboratory practices, an practical exam will be made in which the student is facing the realization of one of the program's practices presented in the laboratory. (38; 39; 40) The reports about practices and proposed problems (; CT4;; CB4 CC3 CT2) will be assessed.

Delivery of proposed problems (CT2, CT4, CB2, CB3, CB4, CC3; CC10) (38; 39; 40; 41; 42; 43; 44).

Attendance and active participation in class (CB2, CB3, CB4, CC3, CC10).

In extraordinary call it will be guaranteed that the student can pass the subject, and if were necesssary, obtain the highest grade, by performing an evaluation test.
