Thanks Parag, for your useful thoughts.
I will just make some comments at this stage.
1) As I understand the new set up (new.p2pu), the idea of "courses" (a programme of study according to a timetable) is deemphasized in favour of a p2p (cooperative study in a more free form manner without a fixed timetable).
For reasons I and others have already given (inability for various reasons to stick with a timetable and subsequent dropping out), I tend to agree with this, although I see nothing wrong with providing an indication to people how long (in hours) they might expect to spend on a given set of materials.
So we should, I think, no longer speak of "Weeks".
2) Once again, under the new setup, I think it is not correct to make reference to "my course" (which in fact does not now exist as originally conceived).
The materials, all free and open, are for the benefit of all, be they organizer (not the same as teacher), participant or follower.
Its our course.
3) ".... is it alright if everyone spends some time revisiting earlier concepts? It would be wonderful if everyone can post on the forums... not only questions but also your thought process, the assumptions and interpretations you are making, whatever doubts/questions some to your mind...
Those who are already comfortable with this material can perhaps help by answering questions in the forum?"
I think this is actually the best way forward.
4) We have not addressed yet the differing "qualifications" of participants/followers. I mean this in two senses, what is expected of a participant/follower (or organizer) and also in terms of what those people already know.
I think there is very likely not a "one size fits all" course of study and it needs to be split up (as Tasks) in some manner (possibly but not necessarily along the lines of a 101, 201, 301) and then participants and followers can dip into the Tasks according to some scheme that they can discuss with organizers or other participants.
(Here I am assuming that "followers" are not going to make any sort of contribution).
5) Lastly, if anyone has specific ideas as to what the Tasks ought to be, then I think they should put them up (things are not set in stone, Tasks can be put up, taken down, amended, reworked according to need.
So Parag, it would be good if you can put up your suggested "Week3" as a Task, "Revisiting Fundamentals" or similar and specify it's purpose and content as well as the target audience.
