A) Expositive lessons in a large group: Lesson given by the teacher that it will be able to have different formats (theory, problems and/or general examples, guidelines of the matter…). The teacher can have audiovisual means and computer support but, students will not need to use them in these lessons. Usually these lessons will follow the contents of a Reference Manual proposed in the Course Guide of the subject. The assistance to these lessons is not obligatory.
B) Interactive Lessons in a reduced group: Theoretical lesson/practice in which set out to and they solve applications of the theory, problems, exercises, … The student participates actively in these kinds of different ways: delivery of exercises to the teacher (some proposed ones in bulletins of problems that the teacher delivery to the students early); resolution of exercises in the classroom, etc. The teacher can have audiovisual means and computer support but, general, the students will not use them in the classroom. Tests of evaluation are included. The assistance to these lessons is obligatory.
C) Lessons of laboratory practices: Are included here lessons that they take place in a laboratory of practices. In them the student acquires abilities specific to a laboratory of analytical chemistry and it consolidates the acquired knowledge in the lessons of theory. The personal work of the student in this activity is more reduced. For these practices, the student will have a handbook of laboratory, that it will include general considerations on the work made in the laboratory, as well as a plan of each one of the practices to be made, that it will appear of a brief presentation of foundations, the methodology and the indication of the calculations to be made and results to be presented. The student will owe to attend to every session of practices having read carefully the content of this handbook. When beginning every practice session, in a classroom, the students answer during 5 or 10 minutes some previous matters that the teacher qualifies and it takes into account for the note of practices. After an explanation of the teacher, the student will carry out individually, or in groups of two, experiences and calculations necessary to the achievement of the practice's objectives, collecting in the diary of laboratory, the development of the practice and appropriate calculations and results, presenting the same day or in the next session results, that they will be assessed. The delivery of a final report is an additional requirement for the evaluation and the term of maximum presentation will be the date corresponding to the official examination of the corresponding announcement. The assistance to these lessons is compulsory. Lacks should be justified by documents, accepting examination and health reasons, as well as those cases considered in university regulations in force. The unrealized practice will be recovered in accordance with the teacher and within the schedule planned for the subject.
D) Tutorships of blackboard in a group very reduced: Tutorships programmed by the teacher and coordinated for the Centre. Mainly, will suppose for every student 2 hours each a four month period. They set out to activities as the monitoring of works directed, clarification of doubts on theory or practices, problems, exercises, readings or other proposed tasks; as well as the presentation, exhibition, debate or comment of individual works or made in small groups. In many cases the teacher will demand to the students the delivery of previous exercises to the celebration of the tutorship. These deliveries will come collected in the calendar of activities that they are going to carry out the students throughout the course of the corresponding subject's Course Guide. The assistance to these lessons is obligatory.Assessment system
The general criterion of evaluation will be taken into account for all the subjects of the Degree in Chemistry (2011-2012 academic year).
1. Assessment system consists of continuous assessment and a final exam. Attendance to at least 80% of all mandatory classes (seminars, tutorials and laboratory practicum) is necessary for a student to be assessed. Justification of absences will be verified by the official control system established in the Faculty of Chemistry.
2. The continuous assessment will be based on the following three components: seminars, laboratory practicum and tutorials which will count in the final note of the student with the following percentages: 15%, 15% and 5%. The sum of these three components will have a percentage of 35% in the final note.
Continuous assessment will be able to consist in exercises given to the teacher and those developed in seminars, work developed in the tutorials and laboratory practicum.
The assessment of laboratory practicum will be based on the grade of a pre-lab quiz, the organization of the laboratory work, the lab performance, the post-lab quiz grade and the lab report.
3. The final exam will include a first part, which will deal with aspects related to the theoretical issues of the course and a second part which will consider issues related to laboratory work. This last will contribute with a 20% to the final note of exam.
4. The global note of each student in the subject will obtain like result to apply the following equation:
Final note = Maximum (N2 , c1 x N1 + c2 x N2)
Being N1 the numerical note of the continuous evaluation (scale 0-10), c1 the percentage of the continuous evaluation, N2 the numerical note of the final exam (scale 0-10) and c2 the percentage of the final examination (65%).
Students with a failing in laboratory practicum cannot pass the subject.
Repeating students will have the same regulation of assistance to the classes that those that are for the first time, with the following exceptions:
a. Repeating students that have approved the practices of laboratory will conserve them the qualification obtained during a maximum of two academic courses. Therefore, they will not have to realise again the practices of laboratory, but will assist to the remaining interactive classes (seminars and tutorships) in equality of conditions that the remaining students, so that they do not lose the right to be examined of the subject.
b. Repeating students that have not obtained the qualification of apt in the practices of laboratory, but have surpassed the corresponding part to the theoretical contents of the subject, will have to realise again the practices of laboratory, conserving them during a maximum of two academic courses the note of the examination and the corresponding to the remaining sections of the continuous evaluation (seminars and tutorships).Study time and individual work

It is advisable to attend expositive lessons.
It is significant to maintain the study of the matter every day.
Once completed the reading of a topic in the reference handbook, is useful to realize a summary including the key points of the topic, which must be remember and ensuring of knowing its meaning as conditions in which they can be apply.
The problem solving is fundamental for the learning of this matter. It can result of assistance to follow these steps: (1) To realize a list with all the relevant information that gives the enunciated. (2) Accomplish a list with the amounts need to calculate results. (3) To identify the equations to be used in the resolution of the problem and correctly apply them.
It is appropriate that students have solved the problems of the bulletins to the seminars. Bulletins will be delivered in the course with time enough so that this is possible.
It is essential the preparation of the laboratory practices before the laboratory lessons. In the first place, they must read the significant theoretical concepts in each experiment and, below, it is necessary to read with attention the practice plan, trying to understand objectives and the development of the proposed experiment. Any doubt that it could emerge should be consulted with the teacher.
