Scientific Methodology is the fundamental axis of research in the Health Sciences. It underpins all innovation with theoretical and empirical models that contribute to a better understanding of reality. The methodology facilitates the detection and resolution of specific problems, and its use and application guarantee scientific rigor.


Pre-course requirements



This course aims:

  • To give basic methodological tools to the student to create a research project. 
  • To know the main sources of information based on evidence. 
  • To train the student to work in research groups. 
  • To teach the student to use assessment methods for different types of studies.


  • CB10 - Acquire learning skills that allow them to continue studying in a self-directed and autonomous mode.
  • CB6 - Knowledge and understanding to provide a basis or opportunity for originality in developing and / or applying ideas in a research context.
  • CB7 - To apply the acquired knowledge, and develop their ability to solve problems in new environments within broader (or multidisciplinary) contexts related to their field of study.
  • CB8 - Integrate knowledge and deals with the complexity of formulate judgments based on scientific evidence, from information that may be incomplete or limited, include reflecting on social and ethical responsibilities linked to the application of their knowledge and judgments.
  • CE1 - Ability to apply the scientific method, the experimental design and the biostatistics to solve a problem or corroborate hypothesis.
  • CE3 - Ability to apply bioinformatics tools used in basic research.
  • CT1 - Ability to work in multidisciplinary and multicultural groups
