Consider the intrinsic cognitive load of
the learning materials (based on learner prior
knowledge) before employing time-compression
in your design because the time-compression
increases the extraneous cognitive load (Pastore,
2009; Ritzhaupt, Barron, & Kealy, 2011; Sweller,
Van Merrienboer, & Paas, 1998). Ritzhaupt
and colleagues (2008, 2011) used learning
materials that might be considered low intrinsic
cognitive load as one study used a discussion
of the educational affordances of Podcasts and
the other two studies used a non-fictitious story
about various locations in Australia. Meanwhile,
Pastore (2010, 2012) used a scientific explanation
of how the human heart works, which might
be considered a higher intrinsic cognitive load.
There were differences between these two studies
in terms of the degree of time-compression the
learners could handle before diminishing the
scores on dependent measures of interest. We
believe the instructional designer must strike
a balance between the intrinsic cognitive load
