Re: [Air-l] how to measure participation rates

I agree with the Nancy's expert opinion -- this is very tedious work. A co-author and I did a similar thing in a study of an online classroom but measured participation by *sampling* from the transcripts of the online classes rather than measuring participation for the entire online conversation. This let us rule out participation rates for the formation of social structure in the class, which was pretty central to our argument.
