This paper presents an innovative approach to introducing pre-service early childhood teachers to math, science and technology education. The approach involves the creation of partnerships between pre-service early childhood and engineering students to conceive, develop, implement and evaluate curriculum in the area of math, science and technology by using robotics and the engineering design process. In this paper we first present the theoretical framework for the creation of these partnerships. We then introduce an experience done at Tufts University in which three different forms of partnership models evolved: the collaborator's model, the external consultant's model and the developer's model. We also present different case studies from this experience and finally we conclude with some remarks and observations for making this work scalable and sustainable in other settings and universities.
