Enhancing learning through use of interactive tools on health-related websites.

The Internet offers a unique means of health promotion through the use of interactive tools like chat rooms, E-mail, hyperlinks and the like. This paper reports a study examining links between learning and interactivity of health-related websites. We address three research questions. First, are tools of interactivity present in health-related websites? Second, how prevalent is the occurrence of these interactive tools for three relevant top level domains (TLD) (e.g. .com, .gov and .org)? Finally, are there differences in how representative websites of diverse TLDs employ these interactive tools along nine dimensions of interactivity? A content analysis of 30 websites revealed that while the majority of sites in our sample do use interactive tools, overall the occurrence is quite low. An examination of the use of tools of interactivity across three different TLDs revealed that .com sites used a greater number of tools, followed by .gov sites and, lastly, .org sites. We also found support for our third research question, that different TLDs employ these tools of interactivity differently. How these differences may impact learning are discussed.
