Video is a powerful medium for communication and learning. With increased accessibility to digital video production equipment, an important question is what role teacher production of video might have in teacher education. Using the lens of design that highlights authenticity, efficacy, and expressiveness as goals, 38 in-service teachers designed videos for use in their classrooms. Interview data investigating the outcome of this activity suggests an effect on teacher thinking in five areas including: (1) instructional outcomes; (2) instructional design; (3) classroom performance; (4) process versus product; and (5) considering the needs of all learners. Data also highlights cautions about the practical use of these technologies in the daily work of teachers. (Contains 1 table.)
