Precision Approach Radar Training System (PARTS) Training Effectiveness Evaluation
Abstract
The use of automated speech technology (AST) in training systems was addressed through the evaluation of the experimental prototype Precision Approach Radar Training System (PARTS). The use of computer speech recognition for simulating the approach control task and for providing input to the automated performance measurement subsystem demonstrated the potential for enhancing automated training. Computer speech synthesis provided the capability to simulate verbal communications from pilots and other controllers, and to demonstrate proper precision approach radar (PAR) procedures by a simulated model controller. The PARTS was evaluated during an eight-month period while being used by students at the Naval Air Traffic Control Schools. Students trained on PARTS were compared with students from the normal PAR training course in a pseudo transfer of training study. No significant differences in PAR performance were found, but the entire range of skills taught by PARTS was not able to be included in the criterion test. Observation, interview, and a performance measurement validation study revealed a number of problems associated with the courseware in PARTS. These problems led to limited acceptance by instructors, but student acceptance was high. A cost-effectiveness analysis generated estimates of potential savings in personnel utilization through the use of AST training systems. Suggestions were made for PARTS design modifications and for future applications of AST training systems, particularly in air traffic control.
