The potential use of social network services (SNS) is being increasing debated in enabling participatory and connected learning culture in K-12 educational contexts. For instance, Ito et al. (2013) suggests that digital and networked media will help to mitigate digital divide between privileged and non-privileged youths by offering new ways of expanding the reach and accessibility of connected learning. However, research (e.g., Hughes et al., 2015; Keren-Kolb, 2010) indicates that pre-service teachers' adoption of SNS (e.g., Facebook, Twitter, blogs) was inclined towards personal rather than educational purpose. So how would you perceive about the opportunity of using SNS to encourage participatory and connected learning culture in the K-12 contexts?
