Optimistic bias about online privacy risks: Testing the moderating effects of perceived controllability and prior experience

This study examined the ways in which Internet users construct their risk judgments about online privacy. The results, based on telephone survey data from a national probability sample in Singapore (n=910), revealed that (a) individuals distinguish between two separate dimensions of risk judgment (personal level and societal level), (b) individuals display a strong optimistic bias about online privacy risks, judging themselves to be significantly less vulnerable than others to these risks, and (c) internal belief (perceived controllability) and individual difference (prior experience) significantly moderate optimistic bias by increasing or decreasing the gap between personal- and societal-level risk estimates. The implications of the findings for research and practice are discussed.

Computer supported collaborative learning: A business simulation activity using social media

Social media are dramatically changing the way we live and make social relationships with others. While students are so immersed in social media in their daily life, social media adoption in classroom has been slow. Educators who wish to experiment with social media for CSCL struggle to find ways to incorporate the expected benefits and advantages of social media to teaching lessons. This paper reports on the experiences of using social media for a business case simulation activity in a higher learning context. Drawing on a qualitative feedback and social media log data of 27 teams of 135 undergraduate students, this paper discusses the advantages and disadvantages of social media as a CSCL tool in classroom, especially in the areas of information sharing and social interaction.
