Spatial dynamics is an instructional strategy whereby students create large scale models that capture the details of a historic event. This Digest discusses classroom floor models and papier mache models. Floor models are best suited to elementary classrooms and middle schools. Papier mache models, appropriate for high school social studies classes, require significant teacher preparation in advance and demand a large commitment of class time. The Digest offers project examples for employing each model in the classroom along with the suggestion to use ancillary materials to enhance the projects. (WG)
