This paper reports on the Digital Historical Inquiry Project, an initiative for developing activities and programs that enable preservice and inservice social studies teachers to learn the methods of digital historical inquiry and implement those methods in their teaching experiences. At one of the project sites, San Diego State University social studies teacher education students are creating pedagogical historical resources called Web Inquiry Projects for using digital primary historical source materials. At another site, Georgia State University preservice and inservice teachers are developing original local digital historical resources for teachers and students to use in their classrooms. Both of these projects are presented as examples of how technology can be lever-aged to enhance social studies instruction.
