Introduction from Dr. Alger: This new column will focus on audiovisual materials, empbasizing videotapes but also covering films and other media. The critical emphasis will be on teaching, and on the ways in which various media programs may be effectively integrated into ongoing or new teaching or learning formats. For this reason, educational consultants as well as media experts will be recruited as guest consultants.Readers who have used media presentations they have found effective are urged to send the names of the titles and distributors to me, at the address below. Teachers who have developed an integrated teaching program using media are also invited to contact me so the program may be considered for review in the column.Our guest consultant this month is Dr. James Lurie, clinical professor of psychiatry and behavioral sciences at the University of Washington School of Medicine in Seattle and chair of the video subcommittee of the American Psychiatric Association's scientific program committee.In this issue we emphasize the use of stimulus tapes-short videotapes intended to stimulate discussion of a specific issue. Dr. Lurie, an expert in this method, presents some basic principles and then joins me in a short dialogue to explore further uses for both teacher and learner.
