In this article Kathleen Roney and MaryAnn Davies report on the use of TaskStream, a Web-based tool to supervise interns and develop reflective practices in a university teacher training program. Providing examples from the internship/student teaching semester, they discuss the use of the tool to support professional development both during the coaching cycle and in the development of e-portfolios. In particular, examples of the tool's use during pre-observation conferencing illustrate its potential to guide and deepen reflection, promote awareness of standards, provide retrievable samples of a candidate's work, and map the connection between that work and a candidate's thinking.
