Teaching methods and learning activities

Lectures and theoretical-practical classes.

Physics Module:

The classes will be online. The didactic content, including resolutions of problems of theoretical-practical classes and tests and exams of previous years, will be made available in Moodle e-learning platform.

Discussion forum in Moodle e-learning platform to resolve doubts.

Geology module:

Presentation and discussion of the contents using case studies. Theoretical lectures will use Powerpoint presentations (including the analysis and discussion of graphs, diagrams, images, photographs and field photos). For the practical component, hand samples of carbonaceous rocks will be used, and also key stats reports of the IEA and DGEG.

Whenever possible, classes will be enriched with lectures by invited experts, webinars, field trips, and study visits to laboratories and industrial units for processing and / or conversion.
