To end this week, I have spent some time reflecting on this question. I'll start with the oft repeated comment: "Teachers are busy people!"
Sure, learning new skills takes time, social networking and learning takes time. Setting up the tools takes time. If seen as a professional learning opportunity, then perhaps the time taken can be justified by most. The only thoughts, I honestly have about time, are "It's about time!"
In fact, time may be running out for educators who are not at least a little informed about the classroom teaching and learning potential of social learning software. You can rest assured, students will soon start to wonder why so little is being done to capitalise on their knowledge and skills with these technologies and applications. Teachers could be facilitating this learning to motivate and engage all students in their learning.
After this reflection, I put this problem aside, remembered the power of positive thinking and I got straight back to my cyberhaunts to follow up the social learning links provided my google reader and RSSMicro alert informtion. I happily receive these updates each day in my mail box. I still enjoy email. No plans yet to abandon that tool.
I have also looked at the Voicethread application and saved the most useful threads. This is a fascinating tool with potential for high impact. Why not explore this tool and brainstorm its potential with friends. Happy web 2.0 learning!
