1. Introduction
The project "Teaching material in digital form for experimentation course subjects in chemistry" has consisted in
the development of an own and common audiovisual and multimedia material in digital format available for subjects
in experimental chemistry of different academic degree courses which are taught in several centers of the Universitat
BARCELONATECH). The authors belong to the Resources Chemistry Teaching
Group (GReDiQ) involved in RIMA (http://www.upc.edu/rima) from Institute of Education Sciences of the UPC.
Chemistry has been included as basic training in most of the curriculums for the new degrees of engineering
which are been implanted in the Technical University of Catalonia during the academic year 2009-2010, in a first
stage, and during the 2010-2011 academic year in a second phase. The subject courses which are based on
experimentation in the chemistry laboratory are scheduled inside this matters. In the method of teaching by skills,
the autonomous labour prior to the laboratory sessions is considered fundamental et al., 2009), since it is
necessary that students know the material handling habits and the safety standards before their arrival in the
