Through examinations of rich learning environments which expand the boundaries of modeling and the practices connected to it, researchers are broadening what modeling means in disciplinary settings. This interactive session brings together a diverse spectrum of scholars to share the practices they have used to expand modeling, how they were used in their curriculum, and the impact they had on learning. This session will serve as a rich opportunity for discussion to help advance the state of the field around what counts as modeling and the role it can play in learning.
