Methodologies
Methodologies Description
Introductory activities Initial session to introduce the subject, where students will be informed about the contents of the course, the teaching methodology -for large and small groups- and the assessment criteria.
Guest lecture / keynote speech The theoretical content will be discussed at the keynote sessions, through multimedia presentations given by the teaching staff. The presentations, covering the basic content and additional material will be available for the students at the Moodle platform, including self-assestment tests.
Seminar The seminars will address the analysis and resolution of some of the previously proposed exercises. In order to make the most of these sessions, it is very important that students work the exercises prior to their resolution in the classroom. The proposed exercises, and the data tables, will be available in advance at the Moodle platform.
Laboratory practice Students will carry out 7 laboratory practices related to the theoretical contents that are addressed in the classroom and that will last 2 hours each. The students will have the script of the work that will be perfomed during each session and the previous materials (readings, videos, etc.) that will be reviewed before starting the experimentation. The teaching staff will explain the most relevant theoretical aspects of each practice. Students must previously read the script before entering the laboratory, and bring it with them.
Each student will individually write a report/notebook of the practices, where he/she will include the objective and theoretical background of the practice, a scheme/picture of the employed material, the performed experiments, observations, and obtained results, as well as extract conclusions and answer the proposed questions. This report will be sent to the corresponding teacher using the Moodle platform, in .pdf format, for its evaluation.
Supervised projects The main target of these sessions is the follow-up of the comprehension of the subject by the students. For this purpose, 8 sessions of 1 hour of tutoring in small groups are scheduled. Students must prepare each tutorial in advance, studying the corresponding contents and solving the exercises of the previous bulletins that will be available at the Moodle platform. Students must upload the solutions of a serie of proposed exercises to Moodle previously to the tutorials. In the tutorials the proposed exercises will be solved and discussed on the board, preferably by the students. Brief short tests by surprise and/or through the Moodle platform can be carried out during these tutorials and they will contribute to the final assessment.
Objective test The degree of concepts assimilation and problem solving skills of the students will be assessed by means of a written exam.

Supervised projects
Description
In addition to the follow-up work in group tutoring sessions, students can apply for individual tutoring, in the schedule set by the teachers, face to face or via Teams.

In the specific case of part-time Students with exemption of attendance, seminars and supervised work will be led through individual and/or group tutoring schedule to be agreed with the teachers.

Assessment
Methodologies Competencies Description Qualification
Laboratory practice A26 A30 A31 B1 B2 B3 B4 The completion of laboratory practices is mandatory. The score of the practices represents 25% of the overall score. The submitted report, the attitude and the work done in the lab will be assessed. To pass the subject is necessary to obtain a minimum score of 5 in this part.

25
Supervised projects A26 B1 B2 B3 B4 The score of the supervised work represents 25% of the overall score. The individual work of the student with the previous questionnaires will be assessed as well as the active participation of the student in the tutorials, the attendance and the qualifications of the short tests in class and via Moodle.

25
Objective test A26 B1 B2 B3 B4 The objective test consists of a number of practical or theoretical-practical exercises, similar to those solved in seminars and tutorials. To pass the subject is necessary to obtain a minimum score of 4,5 in this part.

Assessment comments

To pass the subject it is necessary to obtain an overall rating equal to 5 points or higher (out of 10) in one of the two calls (January and July). A score below 4,5 on the objective test and/or 5 in the laboratory practices implies failing the subject.

The completion of all the
laboratory practices is mandatory to pass the subject. Nevertheless, the student may miss 2 of the 7 sessions. If the student
does not justify the absence, the grade for that practice will be 0 and he/she
will not be able to recover it. If the absence is justified, whenever possible,
the experiments will be performed with another group, and if not possible, they
will not be taken into account in the evaluation. When the final grade of the laboratory practices is lower
than 5, the teacher will return the report, indicating the sources of error,
which must be corrected by the student and delivered for a new assesstment by
the teacher. The qualification of this second review will be definitive and will be applied for the calculation of the global
qualification, both in the first and in the second opportunity.

The attendance to the supervised work is mandatory to pass the subject. Students who attend less than 50% of those tutorials will obtain a qualification lower than 50% in this section for both assessment opportunities in January and July, regardless of their qualification obtained in the short tests during tutorials or via Moodle. In the second opportunity of July, in order to obtain the global qualification, the qualification obtained during the course in this section will be maintained.

In the specific case of students with recognition of part-time dedication
and academic assistance waiver, the mark of the tutored work will be replaced
by that obtained in the personal tutorials, counting as 25% of the overall
grade in the first and the second opportunities. In case of exceptional, and
appropriately justified circumstances, the teacher may fully or partly exempt
any student to perform the continuous evaluation process. In such case the students
will undergo a specifically designed test, in any of the opportunities
scheduled. In this specific case, the student will
perform the laboratory practices in the group with the schedule that best fits
his/her situation. 

"Not attended" assessment mark will be applied when the students attend less than 25% of the planned academic activities (supervised work and practices), and do not assist to the objective test.

Fraudulent performance of tests or evaluation activities, after verification, will directly imply a qualification of failure (0) in the corresponding oportunity.

Other comments

In order to successfully study the subject, it is imperative that the student has a previous knowledge of chemistry and mathematics, according to the level in secondary and high school, such as: chemical nomenclature, balance of chemical reactions, stoichiometric calculations, identification of acid-base character of common compounds, oxidation states calculation of elements in chemical species, logarithms, exponential and basic differential and integral calculus.

With the aim of reducing the paper consumption, and following the guidelines of the faculty´s “Green Campus”, it is highly recommended to send the report in .pdf format.
