Performance-oriented instruction was developed, field tested, and refined in two Advanced Individual Training (AIT) programs--Armor Reconnaissance Specialist (MOS 11D) and Armor Crewman (MOS 11E). Tasks for both MOS (Military Occupational Specialty) were inventoried and the inventories were reduced by eliminating those tasks which are not required for entry-level duty performance. Performance objectives were written for tasks that could be feasibly and appropriately trained. These performance objectives were translated into performance measures and tests. Both programs were revised to include the performance objectives and measures. Field test, data collection, and refinement of the two training programs extended over 10 successive training cycles. The approximate number of trainees involved were 1,000 and 2,000 respectively. Programs were refined on the basis of observation of instruction, results of formal performance examinations, and attitude indicators. The final programs resulted in high trainee proficiency levels, and favorable trainee and instructor attitudes. Questionnaires used to sample trainee and instructor attitudes toward the performance-oriented programs are appended. (Author/BP)
