Methodology
Description of the methodology
Face-to-face and virtual classes
Teaching will be given through theory sessions, problem sessions and seminars, as well as follow-up tests. All these activiries can be face-to-face or virtual depending on the requirements of the current health situation.
Laboratory Practices:
The lab internship program is designed to achieve a dual goal. On the one hand, transfer the learning of the concepts elaborated during the theoretical lessons and discussed during the problem sessions to selected experiments that allow to consolidate the concepts. On the other hand, to provide the students with the necessary skills in the synthesis and characterization of inorganic products through the use of the most common techniques of a synthesis laboratory. Due to the nature of this training, this part of the teaching will be face-to-face, as long as the legal regulations allow it.
About class attendance
As a semi-face-to-face subject, it is compulsory for students to attend the face-to-face allocated theory and problem sessions or face-to-face laboratory sessions. As a result, follow-up tests may be conducted during any of these sessions without prior notice to students.
SAFETY WARNING IN THE LABORATORY
The student who is involved in an incident that may have serious safety consequences may be expelled from the laboratory and suspend the subject.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
Subject Assessment:
The continuous evaluation of the subject has the following fundamental objectives:
1) Monitor the teaching-learning process, allowing both the students and the teacher to know the degree of achievement of the skills and correct, if possible, the deviations that occur.
2) Encourage the continued effort of the students.
3) Verify that the students have achieved the competencies determined in the curriculum.
Blocks: For evaluation purposes, the subject can be considered divided into four blocks (B1-B4). The laboratory practice block (B4), has a special treatment because its special nature. It will be discussed below. Theory blocks B1-B3 will be evaluated with a partial exam (P1-P3) and by means of the follow-up tests that are carried out during the teaching period corresponding to each block, giving rise to marks S1-S3.
Exams: Throughout the course there will be three partial exams (P1-P3), corresponding to the three blocks of theory (B1-B3). All exams will be scored with a grade between 0 and 10.
Follow-up work: A series of follow-up tests will be carried out throughout the course. The set of tests for each block is summarized in a note between 0 and 10 (S1-S3) for the first three blocks. Only well-documented absences (medical certificates, etc.) will allow the student to carry out a follow-up test after the schedulled date.
Laboratory Practices: The grade for the practice block (B4) will be obtained during the laboratory sessions. The exam mark of the practice block (P4) will be between 0 and 10 and will be the weighted average of the marks of the exams taken during the internship period. This grade corresponds to 60% of the grade of B4. The face-to-face laboratory generates a non-recoverable laboratory follow-up grade between 0 and 10 (S4), which corresponds to 40% of the B4 grade. The laboratory is especially face-to-face: it is upto the responsible teacher to decide whether a fault is justified or not. Students who do not assist to all the laboratory days or who have unjustified absences may be assigned the grade failed in the subject.
Students who have taken the subject once and have not passed it, they may keep their practice exam grade (P4) and block grade (B4) for the immediately following course, if they wish, without repeating the laboratory internship, if both grades are higher than 5, as long as the average course grade is greater than or equal to 3.5. If these requirements are met, the laboratory marks obtained will only be valid for the following course, not for subsequent courses.
In the event that the student wishes to keep the grade for the following year, in the current year he/she will not be able to retake the practice exam to improve the grade.
However, the teaching team encourages all students who repeat Chemistry of the Elements to take the practicals a second time and thus better consolidate the theoretical and practical concepts of the subject.
Qualifications:
To pass the subject per course one must obtain a final course grade (FCG) greater than or equal to 5.0 and achieve a grade greater than or equal to 4.0 of each of the blocks (B1-B4) and partial exams (P1-p4).
1) FCG is calculated according to:
FCG = a1 B1 + a2 B2 + a3 B3 + 0,25 B4
where coefficients a1, a2 and a3 are the fractions of the hours dedicated to each block in the schedule of the subject, with respect to the total scheduled hours, normalized to 0,75. The value of the coefficients will be established and inform to students as soon as the final schedule of the academic year is known.
2) The mark of each block is calculated by the mark of the examination P (60% weight) and the mark of the follow-up tests S (40% weight) corresponding to the period of each block. In the case of students who take the single assessment, 100% of thegrade corresponding to the theory part (a1 B1 + a2 B2 + a3 B3) will be that of the final single assessment exam.
Students who do not pass the subject per course (continuous assessment) and students who want to improve the course grade:
Students who do not pass the subject per course, in accordance with the previous continuous assessment scheme, or who want to improve their grade, may take a maximum of two exams to recover the partial ones (P1-P4). The exams that the students take must be those for which the grade or grades of the corresponding block (B1-B4) are the lowest. Students that fail three or more blocks will not be able to participate in the retake exam and will have the qualification of failed.
When the student carries out a retake exam, the P mark of the block will be that of the retake exam, if this is higher than that obtained in the corresponding exam during the course. If the mark obtained in the retake exam is lower than that obtained during the course, the P mark of the block will be the average of the mark of the retake exam and the exam taken during the course. The mark of block B will be the average between the mark P of the exam calculated in the way indicated above and the mark of the follow-up tests S corresponding to the block carried out during the course. S-tracking notes are not recoverable. In the case of students enrolled for unique assessment, 100% of the grade for blocks B1, B2 and B3 will correspond to the grade (or average of the grades if applicable) of the exams of each of the blocks.
To pass the subject after taking the retake exam the students must meet the same requirements needed to pass the subject per course.
Unique assessment:
Students who have taken the unique assessment modality must take a single final test which will consist of an examination of the entire subject syllabus (Blocks B1, B2 and B3) to be taken on the day in which the students of the continuous assessment take the third partial exam and will be graded with the laboratory grade (Block 4).
The grade will be = Final exam grade (75%) + Lab grade (B4, 25%)
If the final grade does not reach 5, the student has another chance to pass the subject through the retake exam that will be held on the day that the continuous assessment students also do their retake exam/s. The grade of the retake exam will replace that of the previous exam to calculate the final grade.
Final grades:
Students who take at least one P1-P3 midterm exam or one of the laboratory practices exams will be graded as “Suspès” (failed), “Aprovat” (passed), “Notable” (notable), “Excel·lent“ (excellent) or “Matrícula d’honor” (honors degree). Students who do not meet the above requirements will be classified as “No avaluable” (non-assessable).
The final marks of the students who pass the subject may be distributed between 5 and, if applicable, 10, always maintaining the order of the students in accordance with the FCG mark obtained, in order to achieve the distribution between “aprovats”, “notables”, “excel·lents“ and “MHs” that teachers consider ideal.
Students who do not pass the subject because they do not pass at least one block, regardless of their overall average, will obtain a maximum final grade of FCG of 4,5.
Students must act honestly throughout the course. Dishonest attitudes (copying, allowing copying or any action aimed at distorting an assessment) in any follow-up test or exam will be grounds for a grade of failed with a final grade of 0 in the subject for all students involved, regardless of the rest of grades obtained. In particular, during the written tests, mobile phones or any other telecommunication devices must be disconnected and stored in bags or backpacks, which must be left on the class platform. In the event that a student wearing an unauthorized device during the exam and /or follow-up test is detected, the student will be expelled from the classroom and will have a grade of failed in the subject.
