General description O principal obxectivo docente desta materia é a de proporcionar ao alumnado as competencias e os coñecementos a un nivel básico sobre conceptos, principios e teorías que describen a estrutura do átomo e da materia, o coñecemento dos diferentes modelos de enlace químico, das forzas intermoleculares e dos estados de agregación da materia. Todos estes aspectos son fundamentais para posteriormente poden afondan noutros aspectos máis avanzados como son as propiedades dos materiais e para poder manipular e deseñar entidades químicas e comprender as súas reaccións e interaccións. Polo tanto, os contidos desta materia aportan coñecementos de base que son fundamentais para poder cursar outras materias do grao en Nanociencia e Nanotecnoloxía.
Así mesmo os coñecementos e competencias desta materia son complementados polas materias Química: Equilibrio e Cambio e Laboratorio Básico integrado do primeiro curso do grao en Nanociencia e Nanotecnoloxía. Estas tres materiais constitúen a formación básica do alumnado en Química.
Contingency plan 1. Modificacións nos contidos

En principio os contidos mantéñense na súa totalidade. Pero no caso de ser necesario e por mor de causas de forza maior poderá optarse por unha presentación máis xeral dos mesmos, pero en calquera caso cubrirá todos aqueles aspectos máis relevantes da materia.

2. Metodoloxías
*Metodoloxías docentes que se manteñen
As metodoloxías manteranse pero pasarán a realizarse na “Modalidade on-line” e dicir empregando as ferramentas das TIC que ten a disposición a Institución. No caso de que parte do alumnado non puidese conectarse e seguir as clases en tempo real, empregaranse medios asincrónicos (correo electrónico, gravacións das sesión expositivas, titorías máis personalizadas...).

*Metodoloxías docentes que se modifican

As probas obxectivas serán probas on line que se realizaran mediante Moodle ou ferramentas equivalentes e facendo un seguimento das mesmas por Teams.

3. Mecanismos de atención personalizada ao alumnado

O alumnado será titorizado mediante a plataforma Teams ou mediante o correo electrónico corporativo.

4. Modificacións na avaliación

Se todo o alumnado puidese continuar coa docencia non presencial sen dificultade avaliarase do mesmo xeito que na docencia presencial.
O alumnado que non poda seguir as actividades on line sincrónicas será avaliado polas actividades equivalentes realizadas de maneira asincrónica.

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.
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
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.
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 this subject.
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.

Workshop
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 Chemistry: structure and Bonding, 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.

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.

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.
