THE COLLABORATIVE WORK ON SCENARIO DESIGN AS A TOOL TO FOSTER TEACHERS’ PROFESSIONAL DEVELOPMENT

In this paper we introduce the idea of scenario design as a method to support teacher professional development (PD). Specifically, we refer to the Meta-Didactical transposition framework to analyse data from a PD programme implemented in Italy, with the aim of highlighting how the collaborative work on scenario design could foster the evolution of teachers‘ meta-didactical praxeologies. To strenghten this analysis, we present teachers‘ reflections about the effects that their collaborative work on the scenario design had on their teaching practices and, in general, on their PD.
