Teaching and learning activities
The course combines theoretical classes with individual work, small group work and autonomous work.
The theoretical classes aim to introduce students to the basic concepts of the discipline and give an instructive and informative character, giving a practical approach, inviting reflection and responding to the posed problem.
The autonomous learning process is also developed using the Moodle platform which includes various resources, such as questionnaires, group work, debates, exercises, videos...
The group work is worked during the theoretical classes, answering questions proposed by the teacher that students should discuss and evaluate among equals, following the guidelines set for each exercise.
Classes will be taught in Spanish, although students' questions will be answered in the language of their choice (Spanish, Catalan or English). In addition, the student can choose to perform the exercises, assignments and exams in Spanish, Catalan or English. The teaching material will be mainly in Spanish, except for articles or graphics that may be in English.
Students may use calculator and form during exams. The form may only contain formulas, not explanations.
Evaluation systems and criteria
In first call:
Participation in class and Moodle platform (problem solving 10%, short questionnaires 10%, practise reports 10%): 30%
Partial exam: 30%
Final exam: 40%
In other calls: 70% of the exam and 30% of the other grades of the course (non-recoverable grade).
1. Plagiarism, copying or any other action that may be considered cheating will be zero in that evaluation section. Cheating in the exams will mean the immediate suspension of the course.
2. In order to pass the course, a 5.0 needs to be achieved in the total calculation and a minimum grade of 4.0 in all valuable parts. If this grade is not reached, the corresponding section will have a zero to calculate the final grade for the course.
3. In the second-sitting exams, the maximum grade students will be able to obtain is "Excellent" (grade with honors distinction will not be posible).
4. Attendance to practical sessions is mandatory to pass the subject.
5. Exchange students (Erasmus and others) or repeaters will be subject to the same conditions as the rest of the students. This is especially relevant with regard to the calendar, exam dates and the evaluation system.
