The idea is that accurate scientific research should be replicable, and through replication we can also identify any methodological flaws in that research.
The above integration strategy presents a major methodological challenge in that standalone intelligent tutoring systems have traditionally been "application islands" that cannot easily interact with other ITS and learning platforms (Roschelle and Kaput 1996).

This is a serious and major methodological problem in that the presence of a third variable completely undermines the conclusion that the death penalty deters.
Although these reflexes were partly responsible for the variations in Δt, the slack test has a notable methodological advantage in that the differences, not the absolute values, of Δt from the multiple trials are used for the calculation of V0, minimizing any systematic errors due to the muscle reflex.

As with most longitudinal studies, the nature of the physical activity data available in the NSHD presents an additional methodological challenge, in that different versions of the questionnaire were used in different waves.
