SIMJLATION UOOEL
The model described here is designed to simulate experimental dnd
quasi-experimental training effectiveness evaluations of aviation devices.
Values are generated by training experts. Major features of the model
include the following:
. programmable for microcomputers
. extendable to different transfer designs /
. helpful in planning field experimental and quasi-experimental .
evaluations of devices
. possible data collection by computer or by questionnaire.
Input to the model comes from the ratings made by flight instructors. These
expert judges make estimates of trials-to-mastery needed in the airplane by
replacement pilots with and without prior simulator training using different
device features. Estimates are made by two different methods to permit a
check on cross-method variance and rater reliability.
VARIABLES
In order to gain a perspective of the scope or size of the model it is
helpful for the reader to examine the levels permitted for key variables.
These are shown in table 1. The model is designed so that these 1 imits can
be changed to fit a variety of evaluation designs (Pfeiffer & Browning,
1984).
