  The aim of this report is to describe a field trial conducted in Italy during
the academic year 2009-10, with primary and secondary school teachers (grades
K-8), in order to test prototypes of "ready to use" kits to be used to
implement PBL laboratory sessions in the classroom. This work is meant to
provide a sort of snapshot of the classroom implementation of the teaching
recommendations (so that any readers can conduct their own analysis). The kits
were designed by matematita (Interuniversity Research Center for the
Communication and Informal Learning of Mathematics, http://www.matematita.it).
I wish to thank the "Ufficio Scolastico Regionale della Lombardia" for
sponsoring the trial.
