My PhD is on visitor interpretation at geosites. I've just had informal feedback on my formal submission of my proposal to the Research Committee and as I expected the methodology section needs more work. Apparently i's unclear what I am "actually going to do" - I am well aware of this but until I start doing some fact finding fieldwork (this summer) I can't develop my methodology, define sites, samples size and so on.
Can anyone suggest some good Research methods texts that I can use to at least show some engagement with methodologies. I am aiming to use a range of methods - interpretation content analysis, interviews with site mangers, observations of visitors, visitor questionnaires.
