Abstract: This paper presents findings from a study in which American teachers studying abroad pinned photographs from mobile phones onto group Pinterest boards and reflected on their own and others’ cultures. Findings suggest Pinterest is a useful tool for promoting personal reflection on media collected in real-time, with the potential to support collaborative reflection on the same media when follow-up commenting or generalization activities are modeled and structured appropriately. Findings have implications for teachers and technology coaches wishing to support common core standards around writing in English and history/social studies.
