Synchronous Communication Tools
Synchronous communication tools enable communication in the form of text, voice, and/or video. Common tools include MSN and Skype, and there are other tools that can be installed on an LMS, such as Wimba, Elluminate and DimDim. Students and teachers can create a virtual chat room, and the presentation or discussion can be recorded for review or for those who cannot participate at the scheduled meeting time.
Social software
Social software sites include social service networks such as Facebook and LinkedIn, and also collaboration tools like wikis and weblogs.
Wikis are great tools for collaboration and discussions. If managed well, students can learn to work with others and resolve conflicts by discussing their opinions and adding to each other’s ideas in the process of producing a piece of work. From my experience in using wiki, I find it more efficient when used by more experienced students.
I have yet to explore the possibility and legal responsibilities of using Facebook or other social service networks to help build learning community.
