An educational system to help students assess website features and identify high-risk websites

摘要

Purpose - The purpose of this paper is to propose an effective educational system to help students assess Web site risk by providing an environment in which students can better understand a Web site's features and determine the risks of accessing the Web site for themselves. Design/methodology/approach - The authors have enhanced a prototype visualization system for helping students assess Web site features and use them to identify risky Web sites. The system was implemented with our graphical search interface for multi-attribute metadata called "Concentric Ring View" and was tested using 13,386 actual and dummy Web sites and 11 Web site attributes. Findings - The testing revealed several distinguishing attributes of risky Web sites, including being related to "play", having monotone colors, having many images, having many links and having many pages with much text in smaller font size. A usability test with 12 teenaged female students demonstrated that they could learn to identify some features of risky Web sites. Originality/value - As students cannot live in a safe cyberspace environment forever, they should be taught how to identify risky Web sites. We proposed an educational system to help students assess Web site features and identify high-risk Web site and verified the effectiveness of this system.
