Are you familiar with social networks? I’m sure you are. Which ones do you prefer? What do you use them for? I’ve been exploring the use of Twitter as a social network since 2007, but I hadn’t been so active up to this year when I really discovered all its potential. During this time I’ve seen how this tool has become more popular and how powerful it is to create and develop our Personal Learning Network (PLN). In my case, having a Twitter account has meant not only sharing and making connections with ELT colleagues and institutions from all over the world, but learning with and from them. Twitter, as other social networks, represents a fantastic opportunity for professional development you should try. If you want to learn more on Twitter, its uses and how to make connections for your PLN, read this document ‘Seven ways to find teachers on Twitter’ produced by Richard Byrne. You can also see ‘Before and After Twitter: Personal Learning Environments’, a very interesting ppt created by Graham Stanley.
