Hello Ann,
I think in this style of MOOC the weekly readings mark a rhythm and add new topics which clarify, expand and connect each week to the previous and following one. Participants, therefore, start discussing each part after having read some enlightening theory and new ideas, which is highly motivating and poses quearies for the week.This is at least what I feel each week when reading the suggested materials.And this is what a course like this is all about.That is, progressing at a certain pace through connections and networks, following others, developing and exchanging ideas, growing and changing in unexpected ways.This is my third with Stephen and George and although I agree moderators must ´ work at a tight schedule´.
