This project investigates teacher mentor and preservice teacher participation in an online simulation of the teaching of literacy in junior primary classrooms. It will investigate how simulation can support preservice teachers to make complex sequences of decisions about the use of language and learning resources, teaching strategies and behaviour management strategies for a class of virtual students. The simulation will employ embedded cognitive tools to support teacher decision making. Once effective simulation learning of teacher performance is achieved, it will investigate the transfer of these skill to the real classrooms.
