The project objective was to develop a basic first aid course which would teach at least as much in 7-1/2 hours as a standard ten-hour Red Cross course. Student performance on empirically revised editions of test questions led to the final design of the course. Data gathered from tryouts of 16mm pilot footage were used to write scripts for the final 35mm color films, six accident vignettes which introduced lessons in accident prevention and emergency care. On one wide-range posttest, out of a possible 326 points untrained subjects achieved a mean score of 85, subjects trained in a standard course 145, and subjects trained in the new course 270. Time-worth estimations and the elimination of common knowledge material contributed to the efficiency of the instructional product. (TI)
