This study tested the proposition that the Augmented Reality Sandbox's (ARS) user-interaction from tactile sensory feedback and a realistic 3D perspective improved topographic map comprehension among novice users with reduced cognitive load compared to the same instruction and practice from a 2D topographic map. Undergraduate students were…

The purpose of this qualitative design case study was to determine the design elements that can lead to technology acceptance of a mobile multimedia tour at an informal historical site. Using rapid prototyping, a tour prototype was developed using a low-cost Website building platform. The tour was then tested with thirteen participants in two…

This dissertation introduces a new multimedia security system for the performance of object recognition and multimedia encryption in security and medical applications.

This study examined the effects of manipulating the modality (text-only, voice-only, voice+text) of a tutorial and restriction (restricted vs. unrestricted) of a simulation's interface on retention and transfer of tutorial content. The tutorial prepared novice students to use Packet Tracer, a simulation developed by Cisco that teaches network…

Background: The current mode of stoichiometry instruction employs a passive pedagogy that consists of students reading, listening, watching, and memorizing disembodied facts, procedures, and principles in preparation for future application. But chemistry students are often subsequently unable to apply this stoichiometry knowledge in equilibrium…
