Syllabus Information

5.1. Methodological overview

The learning process that has been designed for this subject is based on the following:

The subject is practical (7 ECTS). Student learning is based primarily on work in the laboratory that must be accompanied by a previous preparation of the practices. That preparation receives support with some sessions of theory (1 ECTS) and seminars (1 ECTS). In order to guide the learning process, the student must carry out previous questionnaires of each practice that require reviewing and remembering necessary concepts. In addition, after completing the practices, the students must carry out other questionnaires or prepare scripts in which they analyze the data and make the calculations necessary to justify the obtained results and / or observed facts.

5.2. Learning tasks

The program offered to the student to help them to achieve the expected results includes the following activities:

Formative Activity 1: Acquisition of basic knowledge of work in the chemical laboratory (1 ECTS). Methodology: Master classes participatory.

Formative Activity 2: Problem resolution and case study analysis in small group of students (1 ECTS). Methodology: Problem-based learning and questions related to experimentation carried out in the laboratory.

Formative Activity 3: Study, planning, implementation, documentation and evaluation of laboratory practices (6 ECTS). Methodology: Individual study of the preparatory material, execution of the laboratory practice, elaboration of the practice script, and preparation of the answers to the attached questionnaires.

Formative Activity 4: Works of experimentation based on applied cases of properties or products chemicals in common use (1 ECTS). Methodology: Presentation of a problem applied with individual tutorials or in small groups followed by the execution of the practice in the laboratory and presentation and discussion of the obtained results.
