Maha. Two things. I have been reflecting much over the genre within which I want to write, I need to have read much more before I can write in a reflective way to my satisfaction. I am still mapping the terrain. However, this post of Keith’s and my comment will perhaps enrich an expression of what I think, am thinking at the moment – http://idst-2215.blogspot.fr/2013/02/why-rhizomatic-learning-pt-3-etmooc.html. I don’t find the ‘metaphor’ a helpful word now to consider rhizomes as considered in rhizomatic learning. I would suggest something like narrative frame or story space.
