Hi there. I'm new to this forum but was wondering, since discourse analysis is a very broad description, what particular theorist or approach you are using?
In terms of analysis, as a first pass I would suggest a lot of low key familiarity with the transcripts first, just reading them and listening at the same time and getting a feel for the flow and content and 'wholeness' of the data. There is no substitue for a thorough familiarity with the data before you start chopping it up and it may help reduce the anxiety you have expressed at getting started on analysis which can be really daunting. Good luck with it.
