General description A materia “Química” do Grao en Química forma parte dos 60 créditos do Módulo de Formación Básica en Ciencias. A súa finalidade é proporcionar ao alumnado competencias e coñecementos homoxéneos sobre os principios básicos da química sobre os que se desenvolverán, a través das materias específicas, as competencias propias do título.

A “Química 1” é a primeira das catro materias nas que, por razóns de planificación docente, foi dividida a materia "Química" no plano de estudos da UDC. Nela introduciranse, a un nivel básico e meramente cualitativo, a estrutura da materia, átomos, elementos e compostos, partindo tanto do modelo de interaccións entre núcleos atómicos e electróns como dos de interaccións entre átomos; plantexando a relación existente entre estrutura e propiedades e a maior ou menor capacidade dos modelos para xustificalas.

Methodologies
Methodologies Description
Guest lecture / keynote speech In the classes will review the contents of the relevant issues, indicating their most important aspects, particularly those fundamental or more difficult to understand concepts to students. So that students can make the most of the class, the corresponding issue must be first read followed by responses a test to based on this reading. The completion of these tests will be essential in order to be qualified in classes and workshops problems related contents.
Problem solving Problem solving will be in small group and will be dedicated to solving problems and questions raised in advance of the student so that it can work on them before the corresponding session. Periodically in these sessions, the teacher will supervise the work done, not only for assessment purposes, but also to provide adequate support to the study of matter.
Mixed objective/subjective test The test be held on the date set in the timetable agreed by the Faculty Board. It aims to contribute to the assessment of the level of skills acquired by students in the whole course.
Workshop The workshops are designed as a set of eminently practical activities, carried out both in large group and small group, in which the student must participate actively. Its main objective is to complete and deepen the most relevant aspects and / or difficult to understand. They also resolve doubts about any aspect related to problem solving class and workshops, etc
Objective test Periodically, in classes, problem solving or workshops will conduct some short exercices both to assessing student achievement as the teacher's guidance on the issues learn in their class. Besides, this activity tends to encourage the student to perform continuously the effort required to study chemistry 1

Description
The teaching methodology proposed is based on the student's work, which becomes the main protagonist of the teaching-learning process. For the student to obtain optimal performance of their effort it is that there is a continuous interaction and closer student-teacher, so that the latter can lead the first in this process capital. This interaction will especially in workshops and problem solving sessions. Through student-faculty interaction, as well as the different evaluation activities will be determined to what extent the students reached the competency targets set in each unit, and determine students who need personalized attention through individualized tutoring. Therefore, periodically or teachers may call students to tutoring, to be held in the most convenient times for each student, with the intention of receiving the necessary guidance.
Regardless of the tutorials proposed by the teacher, the student may attend tutoring at his own request, as often as desired, and the time that is most suitable.
According to the ""norma que regula o réxime de dedicación ao estudo dos estudantes de grao na UDC" (Art.3.b e 4.5) and ""normas de avaliación, revisión e reclamación das cualificacións dos estudos de grao e mestrado universitario” (Art. 3 e 8b), students with recognition of part-time dedication and assistance exemption should be able to participate in a training methodology and associated teaching activities that would allow the achievement of the training objectives. Therefore, in the subject General Chemistry 1 (Química 1), the percentage of exemption would be preset in a first interview with the students, taking into account once known their personal situations. At this point, students can participate in a personalized tutorial system for guidance and evaluation, with at least five individualized sessions, which will serve for the orientation of students in their autonomous work as well as for monitoring their progression during the course and evaluating the degree of competence development reached. Regarding this last point, the tutorials will serve to carry out those activities included in the Objective Test methodology and which correspond to a 25% of the final grade for the course.

Assessment comments

The rating is the sum of the following contributions:

- Mixed objective: up to 60 points 

- Objective tests: up to 25 points

- problem solving and workshops: up to 15 points. Although responses to pre-test the theoretical sessions are not part of the assessment of the matter, they are considered an essential tool in the teaching methodology designed. Consequently, those students who do not meet any test, or do so in a grossly negligent manner, will not be evaluated in classes problem solving or related workshops.

To pass the subject it will be necessary to get at least 50 points between the different assessment activities (mixed testing, objective testing, troubleshooting and workshops) and obtain a minimum score of 30 points (out of 60) in the mixed test in the firts and second oportunity. If is not possible to achieve the minimum score in the mixed test, although the average be greater than or equal to 50 points (out of 100) will be listed as not passing matter (4.5).

Since the rating is based on the model of continuous assessment, specifically assess student progression throughout the semester could be added maximum of 1 point to the final grade.

Students who do not participate in workshops and problem solvent will score zero points in this section on two occasions or oportunities.

The student will have a rating of not submitted when making less than 25% of academic activities scheduled and is not presented at the mixed objective.

Students to be evaluated in the so-called "second chance" can only obtain qualified with the maximun if the maximum number of these to the corresponding course was not fully covered in the "first chance."

In the case of exceptional circumstances objectivables and properly justified, the professor may waive in whole or in part the student for the continuous process. People in this circumstance must pass a specific test that leaves no doubt on the achievement of the competences of the subject.

For students with a part-time commitment and academic exemption for attendance exemption, the assessment obtained in the activities associated with the personalized tutoring system will correspond to the evaluation of the objective test methodology, that is to say with 25% of the final score. The remaining 75% of said final grade will be determined through the results obtained by the student in the mixed objective.

With regard to successive academic courses, the teaching-learning process, including evaluation, refers to an academic course, and would therefore begin again with a new course, including all evaluation activities and procedures programmed for that course.
