This paper presents an observational study of face-to-face university classrooms and provides preliminary design principles for improving interactivity in "webcast" presentations. Despite the fact that participation and interaction patterns appear to depend heavily on presentation style and class size, useful patterns were observed and analyzed. Design principles presented include the need to support rapid changes in floor control, multiple types of presentation technologies, and the subtleties of awareness between the audience and presenter.
