Teaching methods and general organization

 

Lectures and practical sessions.

En cas de mesures especials degut a la pandèmia COVID-19, les classes teòriques es realitzaran d’acord amb la normativa vigent de la Universitat de Barcelona. Per als experiments es realitzaran en grups però amb proteccions adequades (màscara, pantalla facial, guants, ...), d’acord amb la normativa vigent de la Universitat de Barcelona.

 

 

Official assessment of learning outcomes

 

Continuous assessment

The benefit of theoretical and practical classes is dependent on students’ attendance, as the subject is designed to be interactive. The final grade is calculated according to the percentage weightings shown below:

• Class participation and solving and presenting practical problems: 25%.

• Preparation of a practical report on the laboratory sessions: 25%.

• Written final exam: 50%.

To pass the subject, students must obtain 50% of the maximum grade (100 points).


Repeat assessment

Students who wish to improve their grades can repeat assessment, which consists of an examination comprised of various multiple-choice questions and short-answer questions that can be answered in the same exam booklet. The test is worth 50% of the final grade, which is added to grades for class activities (25%) and laboratory practical sessions (25%).

 

Examination-based assessment

Students may opt for single assessment, if they request so in writing during the period established by the Academic Council. In this case, the final grade is calculated as follows:

• Preparation of a practical report on the laboratory sessions: 25%.

• Written final exam: 75%. The exam may contain various multiple-choice questions that must be accompanied by a brief explanation of the student’s choice, and short-answer questions that can be answered in the same exam booklet.


Repeat assessment

Students who wish to improve their grades can repeat assessment, which consists of another examination.
