Systematically Designed Text Enhanced with Compressed Speech Audio.
Fulford, Catherine P.
This study was designed to determine whether systematically designed text augmented with compressed speech could increase the number of objectives achieved and reduce the amount of learning time needed for mastery of the objectives. Subjects were 78 students from 5 Florida schools with vocational education programs. Their reading levels ranged from grade levels of 3.1 to 12.9, with the mean score of 8.8. The instructional material used was the unit "Good Work" from the Employability Skills Series, which includes a text module covering the introduction, knowledge objectives, and instructional objectives, together with practice activities and audiotapes corresponding to the text. The tape recordings of the text were made by a professional radio announcer at an average speed of 175 words per minute; a compressed speech tape was created at 262 wpm. Subjects were divided into three groups: the control group (n=28) received the text only, and each of two experimental groups received the text and one of the audiotapes (n=28 for normal speech, n=22 for compressed speech). Subjects worked in a laboratory setting and project monitors timed the use of the tapes and administered a posttest. Statistical results of the study showed systematically designed text to be highly effective; all three groups reached a ceiling effect on the mastery of the objectives. Another finding was that the overall variance in the amount of time used for the lesson was reduced by the use of compressed speech. Successful comprehension in combination with the other findings for efficiency, time savings, and reduced variability, demonstrate that the use of compressed speech tapes to augment systematically designed instruction may be a valuable instructional method when a cost-benefit is determined. Data are displayed in 10 tables. (31 references) (BBM)
