Yeah, past tense (and that takes getting your mind around!). Just finished my first draft and it was a T^Y%£^%^ to get going with it -
I just couldn't figure it out at all. Then I realised that I needed to situate my research in the methodological literature (qualitative, quantitative, positivist, etc.) and it was okay pretty much after that. Agree that a good place to start is a very brief intro para linking back to earlier chapters and what's been discussed there, followed by a brief outline of what the methodology chapter includes and why. Best of luck.
