Very recently I have enrolled for a MOOC on Connectivism and Connective Knowledge 2011, because I was attracted by the title (actually only by the connotation of "Connective Knowledge", since I had no idea what "Connectivism" is.
Only then I realized that I had no idea what a MOOC is. To make a long story short, only for learning about this concept, it was worth affording (it was for free by the way). MOOC means Massive Open Online Course.

Having understood now the format, I was nevertheless thrown into it, not very well prepared for it. Used to more traditional course formats, I was very quickly overwhelmed by frustration: How do you read through it all and keep up with everything?

Frustration is gone, I am very excited about the new format - now I am about to learn.
