Cognitive Load within Mixed Reality Learning Environment in Construction Education

摘要: Mixed reality has achieved acceptance within higher education owing to its ability to provide experiential learning with enhanced engagement and attention. In construction education, mixed reality environments can serve as alternative learning platforms for jobsite visits and hands-on learning without exposure to jobsite hazards. However, the design of such learning environments is often oblivious to users’ cognitive states. As human working memory is limited in capacity, cognitive overload is inherent in such learning environments and inadvertently impacts learning efficiency and knowledge retention. This study presents the assessment of a mixed reality environment for learning sensing technologies in construction education and investigates the effects of cognitive load within the learning environment. The study shows the relationship between cognitive load and students’ learning outcomes and the impacts of …
