Use of the Engg Model as illustrated in the above paper.
An illustration of the usefulness of the Engineering Model approach is given by the following
quote: “Females who report a high number of submitted feedback messages have
significantly lower exam scores. On the other hand, male students who exaggerate their
efforts are not in danger of having lower exam scores. This implies that the female
exaggeration bias is small but harmful - the male exaggeration bias is big and harmless. ”
(Wessa 2009c). This result provides valuable information that allows us to make significant
improvements in the statistical learning environment. For instance, female students who tend
to exaggerate their own performance should receive accurate and timely feedback about
their real performance (as compared to other students) based on objective measures. This
form of critical (self) assessment and reflection about student's actual learning efforts should
be made an integral part of the statistical learning environment.
