This paper highlights the iterative development of a dynamic web environment for exploring physics pedagogy: the Physics Teaching Web Advisory, Pathway. The formative evaluation of the system, with high school physics teachers as users, uncovered a number of shortcomings in the synthetic interview presentation of expert teachers offering advice and instructional strategies. The problems and their solutions are discussed, with implications for the design of multimedia conversational interfaces for teachers helping teachers. The paper presents strategies for dealing with video assets to help teachers find relevant material quickly in addressing the pedagogy and full range of content taught in high school physics, while also promoting additional investigation and exploration of the synthetic interviews.
