A new multi-level knowledge mastery assessment system for construction safety education: development and deployment at CityU

Abstract

The hazardous nature of the construction site is a direct threat to human life and its properties. Not only the hazards at the worksite but also the negligent behavior of construction workers can cause harm to others. Thus, workers' knowledge of construction safety, as well as the behavior of themselves and others in hazardous situations, need to be assessed prior to permitting them to enter the site. Thus, this research is focused on developing a comprehensive construction safety knowledge assessment for students of construction-related disciplines. A scenario- based Virtual Reality approach was adopted for this study since paper- based assessment is found ineffective for assessing safety knowledge. The developed multi-level knowledge mastery assessment system was tested with students from the city university of Hong Kong. Task load, application performance, and participant performance were analyzed, and results suggested that the intended objectives of the application have been successfully achieved and have the potential to assess students' safety knowledge comprehensively.
