Hi Pea
I'm in a similar area to you (technology in education, culture, semiotics)... if it helps - mine goes something like: Intro, Lit Review 1 (theory), Lit Review 2 (empirical), Methodology, Pilot, Main Study, Discussion, Conclusions. How I used the intro was as a 'setup' for the chapters that followed basically, so it made sense to put it first, although I guess it depends what you mean by 'intro' and what it contains. Although, generally, the word 'intro' would tend to suggest that it comes first, no? Good luck with it anyway.
