Participatory simulations of disease spread were conducted using wearable computers (badges). Participants interacted (simulating various forms of social network exchange) without knowing whether exchange partners were infected. Afterwards, the NetLogo modeling environment was used to visualize the network. In class discussion, the impact on the social group of different members being infected was explored. This balanced network growth dynamics with disease spread dynamics.more » « less

Generative activities have been shown to support students to engage in space-creating play and exercise their conceptual agency to generate a mathematical space (e.g. Stroup et al. 2004), yet these studies implement generative activities only with their resonating counterpart, classroom networks, technological infrastructures that connect multiple, co-present students into a shared, digital representation. Because these technologies are in continuous redesign and still inaccessible to many classrooms, we need to understand the crucial features their infrastructure provides to the classroom system. By analyzing the strains on the classroom without classroom networks and how they relieved that pressure and revive the system, we found that the collective public displays provided students with a collective orientation and a sense of connection and individualism.more » « less

Fostering productive groupwork is a goal for many educators, but it can be difficult to implement effectively in mathematics classrooms. We have developed an approach, and a corresponding set of new tools, intended to support student participation in mathematically rich collaborative learning activities. This paper provides an overview of this 'Distributed by Design' approach. We elaborate key principles by illustrating three variations, in which we alternately distribute distinct but interdependent mathematical objects, views, or tools to each student in a cooperative group, and ask participants to coordinate those elements in completing a shared task. This approach is implemented with our MathNet software.more » « less
