and task performance that allows one to obtain information on the relative efficiency of
instructional conditions. The method is based on the standardization of raw scores for
mental effort and task performance to z scores, which are displayed in a cross of axes.
Relative condition efficiency is calculated as the perpendicular distance to the line that is
assumed to represent an efficiency of zero. We conclude that the method for calculating and …
This article reports on a calculational approach for combining measures of mental workload
and task performance that allows one to obtain information on the relative efficiency of
instructional conditions. The method is based on the standardization of raw scores for
mental effort and task performance to z scores, which are displayed in a cross of axes.
Relative condition efficiency is calculated as the perpendicular distance to the line that is
assumed to represent an efficiency of zero. We conclude that the method for calculating and …
