  This communication presents the genesis and the implementation of a teacher
module, which is included in an Assistance Tool (AT). The teacher module is
based on a teacher model for which we did a thorough analysis of the state of
the art. The aim of the AT is to help a teacher to design pedagogical devices.
Teachers can formulate their needs (assistance in the design) and the AT can
relieve them from repetitive tasks related to the deployment of a teaching
device (assistance in the deployment).
