Ajay Shankar Tiwari; Kaushal Kumar Bhagat – Australasian Journal of Educational Technology, 2024
This study examined the impact of augmented reality (AR) on engineering education, focusing on spatial visualisation skills and cognitive load in an engineering drawing course. The research is based on cognitive load theory and spatial visualisation frameworks. It compares three AR methods--marker-based (MBAR), markerless (MLAR) and Web-based…

Zu, Tianlong; Hutson, John; Loschky, Lester C.; Rebello, N. Sanjay – Journal of Educational Psychology, 2020
In a previous study, DeLeeuw and Mayer (2008) found support for the triarchic model of cognitive load (Sweller, Van MerriĆ«nboer, & Paas, 1998, 2019) by showing that three different metrics could be used to independently measure 3 hypothesized types of cognitive load: intrinsic, extraneous, and germane. However, 2 of the 3 metrics that the…

DeLeeuw, Krista E.; Mayer, Richard E. – Journal of Educational Psychology, 2008
Understanding how to measure cognitive load is a fundamental challenge for cognitive load theory. In 2 experiments, 155 college students (ages = 17 to 22; 49 men and 106 women) with low domain knowledge learned from a multimedia lesson on electric motors. At 8 points during learning, their cognitive load was measured via self-report scales (mental…
