Don't erase that whiteboard! Archiving student work on a photo-sharing website

Students in physics courses often use whiteboards to brainstorm, solve problems, and present results to the rest of the class, particularly in courses involving col-laborative small group work and whole class discussions. The whiteboards contain a valuable record of students’ collabora-tive work. Once a whiteboard is erased, however, its contents are lost and no longer accessible to students, instructors, or researchers and curriculum developers. We solve this problem using wireless-enabled digital cameras to create an archive of students’ work on the photo-sharing website This provides a persistent record of class activi-ties that our students use frequently and find valuable. In this paper, we describe how this works in class and how students use the photos.
