Methodologies
Methodologies Description
Guest lecture / keynote speech The teacher will present the fundamental contents of each of the topics. For best utilization, students will have to advance the development of these sessions teaching materials suitable for your personal preparation. He taught in large group. All students can consult the teacher any aspect of the matter in the tutorial schedule established for this purpose.
Seminar Sessions devoted to the resolution of problems and issues with the active participation of students. He taught in large group.
Supervised projects In the 8 sessions scheduled entrusted Professor preparing students in writing well in advance of some problems that must be resolved to take classes in a small group. In these sessions, students orally present any problems and answer questions raised about (oral or written) for evaluation.
Laboratory practice In the laboratory sessions students will develop experimental examples of the theoretical exposed in the classroom. Will be essential to achieving the prelaboratorios before the relevant practice (but the student can not perform such practice) as well as keep up to date lab book, according to the instructions of the teacher.
Mixed objective/subjective test The student will perform a joint test for verifying the degree of understanding of the subject has gained. It will include combined theoretical questions, numerical exercises and questions about the practices.

Seminar
Description
The work developed by students in seminars, supervised works and laboratory practice involves personal attention from the teacher both in the resolution of questions as a guide to the preparation thereof, correction questionnaires, understanding fault indication etc..
In addition, Professor mention to the student individually to discuss in more depth how their learning progress of matter.
Moreover, all students can consult the teacher any aspect of the subject in the tutorial schedule established for this purpose.

Assessment
Methodologies Description Qualification
Supervised projects To evaluate the student's progress and assimilation in small group classes will be considered, active participation and oral problems also entrusted the answers (oral or written) to the issues raised at these meetings.
Valuable skills: B2, B3, C1, C3
15
Laboratory practice It will assess the performance of the prelaboratorios, abilities and skills of students in the experimental work, their ability to interpret the results, etc.
Valuable skills: A17, A19, B3, B4, B5, C1, C3
15
Mixed objective/subjective test It will assess the student's ability to express, summarize and develop theoretical aspects of the subject and the resolution of problems and numerical exercises. Also assessed issues related to laboratory practice.
Valuable skills: A1, A4, B2, B3, C1

Assessment comments

-To pass the subject you must obtain a higher or equal to 5 points overall rating (out of 10) in either opportunities. Matter shall not exceed those students be achieve a rating of less than 4 in the mixed test and laboratory practices.

-The performance of the practices is necessary to pass the subject condition.

-In the first and second time, students who do obtuviesen practices and less than 5, have the opportunity to, in addition to the mixed test, perform a specific test related to the labs. The score of this test especcífica replaced the grade obtained in practice for the overall rating.

-Students who do not participate in supervised work will score 0 in this section (20% of the overall grade) on two occasions. The second time the grade obtained in the course for the overall rating will be maintained.

-The student will obtain the qualification of not submitted when making less than 25% of academic activities scheduled, and not presented to the joint proba. As regards the successive academic years, the teaching-learning process, including continuous assessment, refers to an academic course and, therefore, would comezar a new course, including all activities and procedures the Assessment that is scheduled for that course.

-The students tested on the second occasion shall be eligible for honors if the maximum number of these to the corresponding course not covered in full at the first opportunity.

Other comments

To successfully overcome the matter, it is imperative that students have a number of prior knowledge of chemistry and mathematics, according to the level required in middle and high school, including: nomenclature and chemical formula, set of chemical reactions , stoichiometric calculations, acid-base character identification of common compounds, obtaining oxidation states of the elements in the chemical species, management of logarithms, exponents, differential and integral calculus, etc..
