DATA INPUT
Two methods are provided for entering data: the interactive method and
the additive method. The data from both interactive and additive methods
are compatible with the following evaluation design: (Xl) treatment, (;:I
student ability, (X3) task difficulty, and (X4) instructor leniency.
combinations of two levels for Xl and three levels for X2, X3, and X4
require 54 data elements.
Interactive Method
An expert is asked to estimate the trials required for a replacement
pilot to achieve mastery in the aircraft for each set of training conditions
listed in table 2. These estimates are made twice: first, for the
experimental group (e.g., with prior simulator training) and second for the
control group (e.g., without simulator training). Training conditions and
the data collection instrument for the interactive method are illustrated
below as table 2.

The model calls for data on trials-to-mastery for the 27 combinations of
conditions describing the experimental group and the 27 combinations of
conditions describing the control group, a total of 54 conditions. Training
experts need only estimate trials for eight conditions in each group, a
total of 16 conditions. The remaining 38 values (representing the
difference between 16 and 54) are estimated by a regression subroutine in
the model.
