Abstract
This study was designed to address cognitive overload issues through the use of
visual cueing as a means to enhance learning.
While there has been significant research such as use of color for cueing to address
many of the cited problems, there are missing elements in this research that could go a long
way toward designing more effective solutions and teaching methods for Technology
Education students. One aspect that is missing is a better understanding of how color cueing
and narration interact with various aspects of information overload, split attention effect, and
overall instructional difficulty.
When teaching technical topics to a technical or non-technical audience using
multimedia instructions or tutorials, there is a problem of information overload when using
these methods of delivery. Without the proper testing and methods for designing these types
of presentation, the students or the audience the instructor plans to present this information
to may likely experience cognitive overload, reducing the effectiveness of the instructions
and tutorials. Cognitive overload is the result of excessive demands made on the cognitive
processes, in memory particular.
The research was also designed to move beyond theory and to research hands-on
instructional activities with typical students to prove that certain multimedia interventions
reduce cognitive load and make learning more efficient when presenting technical
information.
The principal research uses two rating scale assessment techniques: the SSI and
NASA-Task Load Index (TLX), to assess levels of cognitive load. Previous research
demonstrated that the SSI and TLX had different sensitivities to cognitive load.
The research adds to the existing research base, address some of these missing
elements, and gain a better understanding of how to address the problems that have been
presented above specific to Technology Education students, but equally relevant to other
subject matter.
Visual cueing shows promise as a means to reduce cognitive overload and enhance
learning.
