Développement des compétences cognitives des enfants dans des contextes d'interaction éducative

We present a set of recent studies focused on adults' tutorial behaviours with preschool children. On one hand, we try to account for the development of preschool children's cognitive competences in relation to the tutorial behaviours. On the other, we seek to explain the differences in tutorial behaviours in terms of the adults' representations concerning the adaptation of tutorial modes to children, that are explored using an innovative tool (ORLeP). Finally, we discuss a device for training kindergarten assistants (Educ'Enfance), currently under development, focused on the analysis of educational interactions.
