Abstract
The technique for material analysis Rutherford Backscattering Spectrometry (RBS) has been object of a distance course for the IDIFO Master in Modern Physics. After the introduction of the basic physical models for the interpretation of the phenomena occurring when a light and energetic ion beam impinges on the surface of a solid sample, students were invited to discuss, through network forums, the various models from the disciplinary point of view as well as in the view of a possible didactical path. The second part of the course was devoted to the interpretation of elementary RBS spectra, during which students were invited to complete with their comments and interpretations a table containing some simulated RBS spectra of thin heavy elements films over light substrates. Finally students had to design a didactical path for secondary school students on the basis of the course contents. This contribution for the IDIFO workshop presents the structure of the course and analyzes the contents of the discussion forums.
