Two groups of 15 Administrative Specialists, 7lL Military Occupational Speciality (MOS), participated in four job-task refresher training sessions designed to enhance the typewriting of military correspondence. One group performed under a study training method which allowed use of a Correspondence Manual while arranging materials into the correct format, the second under a recall training method which required reliance on memory. Under both methods, participants received knowledge of results concerning both typewriting speed and accuracy. Straight-copy typewriting performance also was measured at each training session. Both training methods produced approximately a 36% increase in format arrangement speed without an associated increase in error. These benefits occurred regardless of a soldier's time in MOS or on-the-job typewriting experience. Straight-copy typewriting performance remained at an average level of twenty-three words per minute across sessions and did not reflect job-tasks typewriting proficiency. Timely and consistent use of knowledge of results was suggested to be the reason for the typewriting improvements obtained under both training methods. Similar use of knowledge of results in an on-the-job environment also should improve job-task typewriting performance, and thereby reduce the need for a formal refresher training program. (Author/YLB)
