Hi Jeff,
I’m surprised at the number of responses you have on here.Certainly thuought provoking considering I only came on here to find your tweets.
I think your framework will form from the results of the questionnaire, because at the moment you arn’t aware of what the trouble areas are that these participants are going to divulge to you, with grounded theory research the implications of such research will provide you with the basis for a theory to work towards. If that makes sense.
But i do think from the responses on here, that in your introduction you may need to clarify ‘Threshold concepts’ and provide a definition for ‘TEL’
