4. COURSE DESCRIPTION AND TEACHING METHODOLOGY

The theoretical academic sessions  consist of lectures of the program content for the whole group to give students a general and systematic vision of the various topics, highlighting the most important aspects of them, in such a way that clearly offers students the possibility of motivation by those who are experts in the field through dialogue and the exchange of ideas. Prior exposure of the objectives of each chapter and its specific applications to the field of chemistry, will form the basis for focus their interest and motivate their learning. The further development of each chapter is preceded by a general description of contents, illustrated through Microsoft Office PowerPoint presentations in English language, of which the students will have previously on the ILIAS platform, as well as the help of slate in those contents that require it. Audiovisual sessions for a better understanding of the contents are used in some chapters. The active participation of the student will be raised at these sessions.

The practical academic sessions  in the classroom they are an indispensable complement to strengthen theoretical knowledge and deepen in them. Consist in the resolution of both the teacher and students of problems relating to the topics developed in the lectures in large group. In addition, discussions will be held on those topics of greatest interest and relevance. On the other hand, experimental laboratory practices in small groups (max 20 students) will be carried out, in which relevant methodologies and experimental techniques for the study of materials will be made known. Students will previously have a script with the necessary documentation to perform the practices. The practices will consist of a brief theoretical explanation and then the explanation of the operation of the instruments to be used. Afterwards, the student will go through this practice, preparing a report that will be evaluated.

Collective and individual tutorials: Where the supervision of directed works, comments to individual works and the clarification of doubts will take place.

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 indicated in the student's guide. This objective test will consist of answering short questions that address the most important aspects of the subject, as well as solving problems (CC3, CC10) (38; 39; 40; 41; 42; 43; 44).

Laboratory practices: Report Delivery (CC3) (38; 39; 40). Delivery of the proposed problems (CC3, CC10) (38; 39; 40; 41; 42; 43; 44).
