Teaching Methods
Teaching methods: theoretical(15h), problem solving(15h) and experimental work(45h).
Learning Outcomes
Aquisition of basic concepts concerning data analysis of directly and indirectly measured properties: methods to make the best guess of the measured properties as well as of several functional correlation parameters between different physical properties; first principles of the fitting procedure based on minimizing the chi-squared.
Development of experimental and laboratorial competences. Use of a variety of instruments, with relevance to the identification of their characteristics and the origins of sistematic and random errors.
Competences of secondary importance: organization, planning and establishing methodological approaches; scientific communication; experimental data handling and computer representation.
Generic competences: analysis and synthesis; computer knowledge in the field of experimental data handling; working in group; critical reasoning; putting theory into practice; organization and planning; communication; problem solving; adaptability to new situations; research.
