Abstract : The quick evolution of documentation in secondary education has marked and made more complex the information systems and professional practices of librarians. This work tackles the issues of the professionalization of this occupation, the network organization of information systems and the choice of teaching information literacy as an academic subject in agricultural education through a crossed methodological approach.
These issues reveal the necessity to re-consider the existing links between the practices and their theoretical referents as a possible common scientific and professional basis and as a constructive analytical framework. Thus, the information science can bring solutions to the problems raised when trying to define a range of concepts specific to information-documentation and an epistemological reflection.
Focusing on the information science does not exclude the complementary contributions of other disciplines such as sociology of work or education sciences to such issues as professionalization, training and education. The hypothesis of a productive interaction between scientific research and the evolution of professional practices permits to re-consider the place of knowledge and to expect a better apprehension and understanding of the informational phenomena at stake in French secondary education.
