In 1973, the National Medical Audiovisual Center undertook the production of several audiovisual teaching units, each addressing a single-concept, using a team approach. The production team on the unit "Left Ventricle Catheterization" were a physiologist acting as content specialist, an artist and film producer as production specialist, and an education specialist. After educational objectives for the film were written, a storyboard was drawn up for a translation into film. A prerequisite test, pretest, and posttest were written for the unit. Before filming, the final storyboard and script were critiqued by students and additional revisions were made. Filming and editing took a relatively short time. The production was then field tested and found to be an effective instructional device. The systematic team approach to instructional media development was judged an effective strategy for media production, as it required a pooling of the varied talents of team members. (KC)
