Invented by [[Luc Trouche]], more additions by [[Paul Drijvers]]

Instrumental Orchestration ist eine didaktisches Modell von [[Luc Trouche]] (später ergänzt von [[Paul Drijvers]]) mit dem unter anderem der Einsatz von Technologie im Mathematikunterricht beschrieben werden kann.

!! Definition

==Definition==

The teacher's intentional and systematic organisation and use of the various artefacts available in a learning environment in a given mathematical task situation, in order to guide students' instrumental genesis.

!!! A didactical configuration

===A didactical configuration===

An arrangement of artifacts in the environment, a configuration of the teaching setting and the artefacts invovled in it

!!! Exploitation mode

===Exploitation mode===

The way the teacher exploits the didactical configuration for her didactical intentions: decisions on the way a  task is introduced and worked, on the possible roles, of the artifacts and on the schemes and techniques involved
