Meta-orchestration instrumental for teacher education

International audienceThis paper discusses the theoretical model Instrumental Meta-orchestration, which has been developed focusing on the formation of future teachers to use digital technologies integrated with mathematics teaching. A meta-situation of formation emerges from the experience of an instrumental orchestration with a mathematical situation, an experience that points out the need to create a formation model that favors a discussion about Instrumental Orchestration and the learning of its main elements and theoretical assumptions. It was also created a microgenetic analysis structure to identify events that demonstrate the participants' understanding, doubts or non-comprehension about the theoretical model
