In the event of an emergency aboard a vessel, the sound powered telephone talkers have the responsibility of receiving damage reports from various portions of the ship, logging them, and passing them on to a Damage Control Assistant (DCA) who then can direct the damage control procedures. The talker must not only be thoroughly familiar with sound powered telephone procedures, but must also be familiar with the predesignated symbology for reporting the type of damage which has occurred. In order to train enlisted personnel in sound powered telephone procedures and logging damage reports for the DCA, a programed instruction audio tape was developed. The audio tape was used with the "Audio Notebook," a miniaturized, multitrack tape recorder which provides volume storage and selective playback for learning and practice of subject matter. When this program was used aboard ship, all students were able to qualify. When the program was used with 60 students fresh from recruit training, their improvement was also statistically significant. (JY)
