Teaching of the subject is performed by:
A) Expository classes that will serve to tutor the students in their personal work.
B) Seminar classes in which the lecturer, in addition to solving problems of a practical nature, will solve the doubts raised by the students when solving the proposed exercises or questions, as part of the personal work to be done by the students. In addition, within these classes, the students must solve and hand in any exercise proposed by the lecturer, which will serve to assess their level of understanding and for the mark of the continuous evaluation. Attendance at these classes is mandatory, since the activities carried out in them are taken into account for continuous assessment.
C) Laboratory practical classes. For these practices, the student will have a laboratory practice manual. The student must go to each practice session having carefully read the content of this manual. At the beginning of each practice session, in a classroom, the students respond for 5 or 10 minutes to some previous questions that the teacher qualifies and takes into account for the practice mark. After an explanation from the teacher, the students will carry out the experiences and calculations necessary to achieve the objectives of the practice, collecting in the laboratory notebook the development of the practice and the calculations and results that proceed, presenting the results, which will be evaluated. The delivery of a final report is an additional requirement for the evaluation. Attendance at these classes is mandatory. The absences must be justified documentary, accepting examination and health reasons, as well as those cases contemplated in the current University regulations. The practice not carried out will be recovered, if possible, according to the teacher and within the scheduled time for the subject.
D) Blackboard tutorials: Tutorials scheduled by the teacher and coordinated by the Center. In general, they will mean for each student 2 hours per semester and course. Activities such as supervising tutored works, clarifying doubts about theory and/or practices, readings, problem solving, exercises and / or other tasks are proposed, as well as the presentation, exposition, debate or comment on individual or small group works. The teachers will require the students to hand in the exercises and/or the work done in the classroom. Attendance at these classes is mandatory, since the activities carried out in them are taken into account for continuous assessment.
The general, evaluation criteria of the courses of the Degree in Chemistry will be followed.
1. Student assessment will have two components: continuous assessment and final exam.
a) Non-attendance to any seminars and tutorials will lead to a zero mark in all the assessment activities carried out during that sessions. Anyway, the students can attend the final exam.
b) Attendance to lab sessions is compulsory. In order to pass the course, students shall also pass the practical sessions.
2. Assessment of seminars and tutorials will be based on the results of the different assessment activities carried out during the course. The continuous assessment (N1) will have a weight of 30% in the final mark, consisting of:
- Exercises and tests carried out in the seminars (Sem): 10%
- Work during the seminars and tutorials (Tut): 5%
- Lab sessions (pre-lab test, tidiness in the lab, development of the practical work, and final report): 15%
3. The final exam will consist of a set of questions to verify the student's skills. The final exam will include questions related to laboratory work which will represent a 15% of the exam mark (N2).
4. The student's final mark will not be lower than the final exam mark nor the mark obtained weighing the continuous assessment with the final exam. The weighted average of the continuous assessment with the final exam will be calculated according to the following formula:
Final grade= Maximum (0.30 x N1 + 0.70 x N2, N2)
N1= grade corresponding to the continuous assessment (0-10)
N2= grade corresponding to the final exam (0-10)
The students must obtain a PASS grade in the practical sessions to pass the course.
The course will not be passed if the final exam mark is less than 4.0 out of 10.
Students repeating the course will have the same consideration than other students as regards attendance to lectures, with the exception of lab sessions. If a repeating student has passed the lab sessions in former years, (s)he will be exempted to perform lab experiments again and will retain their lab-related grading for a maximum of two academic years. Hence, they do not need to repeat lab sessions but will need to attend the remaining interactive lectures (seminars and tutorials).
However, students can always repeat lab sessions if they want, even if they have passed that part in previous years. In this case, they just need to communicate that to the lecturer.
In case of fraud or unethical behavior during the completion of tests, exams or assignments, the USC regulation as regards academic performance and grading (“Normativa de avaliación do rendemento académico dos estudantes e de revisión das cualificacións”) will be considered.
