BASIC AND GENERAL
CG2 - That they be able to gather and interpret relevant data, information and results, obtain conclusions and issue reasoned reports on scientific, technological or other problems that require the use of knowledge of Chemistry.
CG3 - That they can apply both the theoretical-practical knowledge acquired and the capacity for analysis and abstraction in the definition and approach of problems and in the search for solutions in both academic and professional contexts.
CG4 - That they have the ability to communicate, both in writing and orally, knowledge, procedures, results and ideas in Chemistry to both a specialized and non-specialized audience.
CG5 - That they are able to study and learn autonomously, with organization of time and resources, new knowledge and techniques in any scientific or technological discipline.
TRANSVERSAL
CT9 - Develop skills in interpersonal relationships.
CT10 - Acquire critical reasoning.
CT11 - Achieve ethical commitment.
CT8 - Being able to work in an international context
SPECIFIC
CE11 - Understand the relationship between macroscopic properties and properties of individual atoms and molecules: including macromolecules (natural and synthetic), polymers, colloids and other materials.
CE13 - Be able to demonstrate knowledge and understanding of essential facts, concepts, principles and theories related to the areas of Chemistry.
CE15 - Be able to recognize and analyze new problems and plan strategies to solve them.
CE18 - Be able to carry out standard laboratory procedures involved in analytical and synthetic work, in relation to organic and inorganic systems.
a) Expository / interactive classes developed by the teacher
b) Laboratory practical classes. Given the reduced number of hours available, they can be replaced by 1) virtual classes with the exhibition through videos of practices related to some of the most important topics and / or 2) exhibitions of related works by the students.
c) Tutoring
According to the document "Guidelines for the development of safe face-to-face teaching, academic year 2020-2021" two new possible scenarios are contemplated for the teaching methodology in the event that it is not possible to develop the indicated scenario of adapted normality. The new scenarios are included in the observations section under the title of the Contingency Plan.
The qualification will be made through continuous evaluation and final exam.
The continuous evaluation will be carried out through written tests during the course and the presentation of works proposed by the teacher.
The final grade will be: 25% continuous assessment and 75% final exam.
In accordance with the general evaluation criteria contained in the Grade Report, the student's grade will not be lower than that of the final exam or that obtained by weighing it with continuous assessment.
In the seminar classes the competences will be evaluated: CG2; CG3; CG4; CG5; CT9; CT10; CT11; CE11; CE13 and CE15.
In the laboratory classes the competences will be evaluated: CG2; CG5; CT6; CT7; CT8; CT9; CT10: CT11 and CE18
In the tutorial classes the competences will be evaluated: CG3; CG4; CG5; CT6; CT7; CT8; CT9: CT10; CT11 and CE15
In the final exam the competences are evaluated: CG2; CG3; CG4; CG5; CT10; CT11; CE11; CE13 and CE15
The suitable one for the understanding and assimilation of the knowledge developed throughout the course and that, in any case, will depend on the abilities of each student.
Contingency plan
According to the document "Guidelines for the development of safe classroom teaching, academic year 2020-2021", two possible new scenarios are contemplated for the teaching methodology and the evaluation system in case it is not possible to develop the adapted normality scenario :
Scenario 2: distancing (with partial restrictions on physical presence).
• The expository teaching will be non-face-to-face and the seminars and practical laboratory and computer classroom. However, the distance measures imposed may suppose that it is necessary to reduce the size of the practice groups and, therefore, the number of contact hours (up to a maximum of 50% of the practical hours of the subject) that must be complemented with non-contact activities.
• The tutorials will preferably be virtual.
• The final tests will preferably be telematic.
Scenario 3: closure of the facilities (impossibility of teaching face-to-face).
• Teaching will be completely virtual, with synchronous or asynchronous mechanisms.
• The tutorials will be exclusively virtual.
• The final tests will be exclusively telematic.
For virtual teaching, the Moodle platforms will be used for the final test and continuous assessment and MS Teams for the expository classes, seminars and tutorials.
