I didn't really know very much about grounded theory before reading this book. Recently I read Vygotsky's Thought and Language and I found a remarkable number of parallels with grounded theory. Grounded theory tries to encourage researchers to put off finding an over-arching theory with which to fit data into. In some ways it can be seen as a response to Kuhn and his paradigms. The problem is that we tend to be tied to ways of thinking and so too much research is based on theories looking for supporting data. Grounded theory tries to hold off fitting data to theory for as long as possible.
There are paradoxes and impossibilities to all this, of course. And the more one thinks they have no guiding theory underlying how they are constructing their research, the more likely it is that they are unconscious of that guiding theory - which is, of course, the worst of all possible outcomes. However, I don't think that kills the grounded theory project in its cradle. Some of the methods, if used reflexively, would seem to be very worthwhile.
I'm struggling to work out if grounded theory is a method or a series of tools. Personally, I prefer to think of it as the latter, but I can see that there are good reasons to preferring to think of it as a method. My preference for the tools analogy due to that being how I plan to use it - or the bits I want to use - in my research.
We start with a coding book. Any theory is a way of categorising reality and so how you choose to code what you see is going to have a profound impact on what you end up seeing. What is interesting here is that grounded theory recommends coming up with a series of gerunds - verbs that have been turned into nouns by adding -ing to the end of them. Why? Well, these keep their verb flavour and force the researcher to look at processes rather than things. Processes are always relational, and it is relationship that matter.
Coding is seen as an open and fluid process. It is probable that once started the researcher is likely to find other codes to apply to the data - and this is grounded theory's strength, that it is provisional and comes out of a direct engagement with the data.
As the data is being coded the researcher writes memos. These are essentially reflections by the researcher on what it is they are seeing coming out of the data. As such these provide a kind of history of the thinking of the researcher along the path of doing the research. The researcher also is seeking to move from the concreteness of the data towards tentative generalities on which theory can be built. Theory is that which ties together various facts, and so these memos are seen as the first step on that process. They form a kind of 'enforced noticing' if you like. The researcher is forced to engage with the data to see what general principles come out of how they have been coded.
Out of this process the gaps in the research will be highlighted - and so the researcher will be forced to go back and re-sample their data in the light of the gaps this move to the theoretical has brought about. This is called Theoretical Sampling - and ought to then bring about a theory that has been grounded in the data. At the end of the process we once again reflect on the entire process.
And this is the main benefit of grounded theory, to me, this reflexivity. Every move toward the theoretical is both deliberate and deliberated on. I don't think this is nearly enough to ensure that theory is free of past influences - such freedom is impossible and probably not really worthwhile. All the same, the benefit here is that the researcher is constantly reminded of the dangers of moving too far away from what they are being told by the data - and that has to be a good thing. While this might not be enough to ensure 'objectivity' it surely provides tools that support the researcher in what is a very worthwhile aim.
The thing I particularly like about this method is that it forces the researcher to be a bit anally retentive. I'm really not very anally retentive at all and so any method that forces me to stop 'looking at the big picture' and 'just getting on with it' has got to be a good thing.
