Interactive whiteboards (IWBs) are increasingly prevalent in U.S. classrooms. Yet, little is known about how this tool is being used to teach social studies. This case study through classroom observations, interviews, and student focus groups examines how two fifth-grade teachers use the IWB to teach U.S. history. The data indicate that when the teachers were observed utilizing an IWB in their social studies instruction, they shifted away from the student-centered instructional practices observed when they did not use the device. Their IWB-centered instruction was teacher centered, utilizing the device predominantly for projection. This trend is likely due to a lack of confidence in how to integrate the IWB technology with social studies pedagogy, as well as a perceived lack of ready-made social studies materials for the IWB. Hammond and Manfra's (2009) giving-prompting-making model of technology-based social studies pedagogy was used to frame the teachers' instructional practice.
