Modern technology not only greatly expands the variety of media available for science learning (e.g., dynamic computer visualizations, interactive simulations, computerbased modeling environments), but also significantly enhances opportunities for supporting collaborative learning. The studies in this symposium examine collaboration as a scaffolding strategy in science classrooms that use technology-enhanced visualizations to aid student learning. Together, they consider various forms of collaboration, including co-construction, critique, discussion forums, knowledge distribution, and peer instruction in technologyenhanced learning environments. This interactive poster session will engage presenters and participants in a conversation that explores the following questions: What opportunities exist for different forms of collaboration in science learning environments that employ interactive visualizations? How can we best design technology-enhanced science visualizations to foster collaborative learning? How can we harness the power of interactive visualizations to enhance the effectiveness of collaborative learning? What are the affordances and constraints of different forms of technology-enhanced collaboration for students trying to understand complex scientific topics?
