Given that social studies pedagogy often runs in direct opposition to how students best learn, social studies teacher preparation must intervene by providing teachers robust experiences for inquiry, interpretation, creation, and personal meaning making. Digital history represents an area of innovation in social studies that can be a useful context for providing such interventions. This research applies a design-based methodology to develop a teacher education activity that reflects research on digital history and how students learn best by constructing and extending (...) prior knowledge, processing information into knowledge, and scaffolding. Design-based research has proven to be suitable as an intervention for classroom settings in that it can be rapidly refined in response to ongoing research on an intervention. The research asked what methods and tools can teacher educators use to promote digital history in their classrooms. Through the project, 200 teacher education students, over four iterative design phases, learned to process historical information into knowledge using technology to communicate refined versions of their knowledge to outside audiences. Seven design factors and six commonalities and differences were identified as influencing the design process. The results of this design-based research informed the development of generalizations and guidelines for designing similar digital history projects. (shrink)
