Learning activities and methodology

Lectures where the theoretical concepts are explained (PO: a)
The lecturer will provide a file with the following information (1 week in advance):
- Main topics to be discussed during the session
- Chapters/sections in each of the text books provided in the bibliography were the studend can read about these topics
Activities in groups (~ 40 students divided in groups of 2-3 people) to solve problems (PO: a, d).
The main skills to be developed in these activities are:
- To understand the statement of the problem (for instance drawing an scheme that summarizes the statement)
- To identify the physical phenomenon involved in the statement and the physical laws related to it.
- To develop a strategy to reach the objective (for instance breaking the problem in small subproblems).
- To be careful in the use of mathematics
- To analyze the reasonability of the result (is the final result reasonable?, are dimensions consistent?)
Small works focused on the search of scientific information in different sources (mainly internet). (PO: a,d)
Laboratory sessions (~20 students divided in groups of 2 students). (PO:b, d)
The main skills to be developed in this activity are:
- To understand that physics is an experimental science and they can reproduce the laws that have been theoretically explained in the lectures.
- To use scientific instruments and to be careful in its operation.
- To be careful in the acquisiton of the experimental data.
- To learn the basis of the management of a scientific data set.
- To write a report with the main results of the experiment.
- To reason in a critical way these results: have we achieved the goals of the experiment?
