Stories are the most natural form of communication and learning among humans. In this paper, we describe how we have designed and implemented an case library of technology integration stories to support pre-service and in-service teachers learning how to integrate technologies into their teaching. The case library was built using the artificial intelligence theory, case-based reasoning. We also describe how this case library may be used as an electronic performance support system for in-service teachers and a learning support systems for pre-service teachers engaged in case studies.
