AN ON-LINE PROFESSIONAL ENVIRONMENT TO IMPROVE THE TEACHING OF STATISTICS

We present the foundations of a professional development program supported by the European Union (COMENIUS Project 226573-CP-1-2005, developed from December 2005 to December 2008), whose objective is to propose professional development strategies that foster the integration of the teaching and learning of statistical reasoning in European schools. The intention of the program is to promote professional development through cross-cultural collaboration between teachers of different European countries. To this end, an online professional learning environment has been designed. We present the referents that allow us to interpret the teachers' reasoning and to understand how their intervention in the teaching and learning processes evolves.
