Constructivist project based learning design, a cybernetics approach

We approach the progress dynamic of project based learning from a systems theory point of view. We model open loop PBL mathematically and analyze its robustness and show its weakness. Then we propose an effective model of conducting complex PBLs by dividing the whole PBL process into sub processes of lower complexity and introduce feedback for each one. In the course of this paper, we show how adopting the proposed model could significantly improve the process of PBL tuition. We present simulations of the higher robust performance of the new model. This paper presents one novel approach of educational design based on cybernetic methods.
