I have been working through week 4 today and getting prepared for my next badge. I noticed the end of week 4 talks about Personal Learning Environments. This prompted me to look back to the good old OU H800 course from last year, where we were asked to graphically define our own PLE. I used a mind mapping tool called Spicynodes, which I rather enjoy using. You can find my PLE at this location.
I am probably going to have to revise this, I am likely using even more tools nowadays!
