It's All Starting To Click!

Within the early stages of the Ph.D. you shall be forgiven if you arrive at early conclusions regarding the relationship between philosophy, methodology, methods and data. It is easy in the early stages to subscribe to the notion that, for example, qualitative data and qualitative inquiry in general is situated only within a combined Philosophy of relativist ontology / subjectivist epistemology; similarly, it’s easy to subscribe to the notion that qualitative data comes only from interview methods.


Why is this the case?


I arrived at these assumptions prior to and early in the Ph.D, based on what I was reading at the time. Research papers gave the impression that statistical analysis and experimental designs aligned only with objectivist perspectives and that qualitative data and associated analysis aligned only with a subjectivist perspective. However, the more I read the more I questioned my own assumptions about the relationship between philosophy, methodology and methods and found that this relationship is far more dynamic than I had imagined, and that really there is no such thing as a linear relationship between them. This relationship is fluid, and the more I read and thought about my own beliefs I am now finding much fluidity even between ontological and epistemological perspectives, and this is what I shall initially call Design Flexibility.


Design Flexibility


Design flexibility does not adopt a sceptical perspective of the existence of an actual relationship between philosophy, methodology and methods, but is sceptical of any assumptions of a linear relationship where a particular perspective entails the choosing of other specific perspectives. There is no rejection to the idea that ontological perspectives influence epistemological perspectives, which in turn influence methodological perspectives, but there is a rejection of a predetermined linear relationship. More recent methodological textbook authors arguably lean heavily in the direction of philosophical and methodological dynamism therefore acknowledging that reality and our understanding of reality is so complex that there are limitless ways in which reality can be perceived and the way in which we come to know this reality, which influences the way in which we explore this reality.


Applied to my own thinking, my philosophical beliefs line with subtle realism, developed by Hammersley. Typically, a realist ontology is accompanied by an objectivist epistemology suggesting a reality independent of our thinking and knowing, and knowledge of this reality being discoverable and accessible within this reality as knowledge itself exists independently of our minds. But design flexibility suggests that even though the realist ontology and objectivist epistemology is commonly observed particularly in the natural sciences, it doesn’t mean that they are in a strict dependent relationship. Hence, my epistemological beliefs align with subjectivism: I perceive a reality independent of our minds but we do not have access to all knowledge and truths of this reality. We will never come to fully know or grasp objective reality and truth of this reality through our perceptions and theories about what is occurring within this reality: the best that we can do, and the best that I can do with the theory that I am developing, is to represent certain actions and events within reality without claiming that I know for certain that what I theorise is really what is happening.


Another example of design flexibility is at the methodology level. Typically, qualitative inquiries are not associated with realist philosophies as they are mostly aligned with constructivist or interpretivist based perspectives (relative ontology; subjectivist epistemology) but I am attempting to place my qualitative inquiry within the context of realist ontology, subjectivist epistemology with the type of subjectivism leaning towards interpretivism. There is a small but growing body of literature that suggests the usefulness of qualitative inquiries being situated within this philosophical context therefore it is an aim of mine to attempt to contribute towards further discussion and development of this area of qualitative inquiries.


Then there are the methods and various qualitative approaches within which these methods are situated. Qualitative inquiries can not only be situated within a variety of different ontological and epistemological combinations but also adopt a variety of possible different general approaches with the most typical being ethnography, phenomenology, grounded theory and case study, but there are many more approaches and each of these can typically be combined e.g., an ethnographic case study. The qualitative approaches that shall be used are case study and grounded theory.


And to add to this already banging-head-on-keyboard-moment-as-you-work-through-all-this-stuff are the various types of case studies and the various types of grounded theories that have to be selected or further developed if no existing version exactly matches research aims and general context of the research design. For example, because of the adopted philosophical perspectives, I have to not only think of ways in which the particular type of case study and particular type of grounded theory adopted, or further developed, in this research work with each other, but work with each other within the philosophical perspective, which should lead to plenty of opportunities to expand on current discussions and development of research designs.


What has been discussed in this blog post is not the full story either: there is so much more beyond what I have discussed here but for the purpose of this blog (and my sanity) I have kept discussions brief and relative to my continuous thinking and development progress,


There you have it: completely and utterly bewildering and confusing at first, but keep fighting your way through because it is worth it. I think, perhaps, yeah, it is, I’ll let you know in time……..

Brief Introduction to Realism and my Research: context and boundaries

Long term blog readers will no doubt have had their brains melted as I have debated and discussed the use of different philosophical perspectives as a guide for the research methodology, beginning with a constructivist perspective before navigating towards and settling on a realist philosophy. Subsequently, methodology has transitioned from pure grounded theory methodology, to a mixed methods methodology with grounded theory used as a method, before navigating towards and settling on a case study methodology using grounded theory as a method, using a realist philosophy to guide the methodology. Feel free to have a search about my blog to find relevant discussions!

I have been thinking about this for a long time now, and a realist approach is the only overarching philosophical approach that makes sense to the context of my research; therefore, I am beginning to understand and further develop my philosophical justifications and arguments for realism as a philosophical drive for my research design. It is such a complex area however with many variants, directions, debates, discussions and applications; therefore, there needs to be a series of limits set to what can realistically be explored and discussed in the thesis, and on this blog. These limits I find come naturally within the boundaries of my research.

Limits Of Realist Discussions

Different people will have different approaches, but for me so far it’s easier to contextualise discussions of realism within the boundaries of my own research. It is important to lay out a set of limits because it will keep you focussed about what you need to explore, and what you need to discuss in terms of your philosophical justification and the way in which it applies to your research methodology. It’s easy to travel off in different directions as realism like any philosophical perspective is vast, complex and well debated and discussed.

The following are limitations that I have placed on my own investigations and discussions of realism:
· I talk about realism only in the context of social sciences and not the natural sciences
· I talk about realism only in the context of qualitative research
· I talk about realism only in the context of case study methodology
· I talk about realism only in the context of grounded theory method
· I talk about realism specific to the type of case study and grounded theory used

Obviously this blog is not as “formal” or “academic” as the thesis therefore I shall be a little less restrictive about these compared to the thesis so I can talk about, for example, realism in other methodologies and compare to the selected methodology of case study in general. I can also do this in the thesis but it would be more specific, e.g., I assume it would be important for example to compare the use of realism in phenomenology and case study relative to the phenomenon of investigation, as this can contribute to the philosophical justification of the selected philosophical perspective.

A Guide, Not A Strict Structure!

It’s important to some extent to treat these limits as a guide rather than an absolute rigid structure of discussions. Think about it as being set free within the boundaries of your research as defined by the discipline in general, and the overall research design. There is little point, for example, in talking about realism in phenomenological research if your research design is not based on phenomenology; however, that doesn’t stop you from discussing realism applications within that methodology if you can apply it in some way that is relevant to your own methodology. That’s an example of what I am talking about in terms of being set free within the boundaries of your research.

Now that limits have been set, key questions must be asked that shall help develop an overview of what needs to be known, and this is the subject of the next blog post.

Philosophical Domains

Three Domains Of Philosophy


I have now at this point identified three domains of Philosophical considerations that a Ph.D. candidate might want to engage with whilst developing a philosophical understanding of their research. The three domains are:


The Philosophy Of The Self


This domain deals with the ontological and epistemological beliefs of reality, and therefore the way in which we situate ourselves within the context of the perceived reality. These beliefs form our perception of reality and answer questions such as: in what way do we perceive reality itself? In what way can we come to know this reality that we perceive?


At the ontological level there is a spectrum of beliefs that span from realism on one side to relativism on the other side with the different points in between determining the extent to which aspects of reality is either dependent on or independent of the actions of the mind. A realist perceives a reality that is independent of the thoughts and actions of the mind but the points along the spectrum progresses from a view of reality as being fully independent of the mind to a view that suggests there are aspects of reality that are dependent on the mind. On the relativism side, different flavours or points of relativism progresses from aspects of reality that are dependent on the mind to a reality that is fully dependent on the mind or in other words that reality is nothing more than what exists within our minds; our perceptions and beliefs mirrors reality itself.


Epistemological beliefs relate to the way in which we come to know reality and from what I can understand there are more theoretical categories of beliefs at this level than at the ontological level and it would take a long time to go through each theory on a single blog post but suffice to say that epistemological beliefs are, like ontological beliefs, situated along a spectrum with objectivism on one side and subjectivism on the other side. Objectivism states that knowledge of reality already exists therefore knowledge of reality is discovered and not constructed; knowledge of reality is attained through the belief that reality is a single layer, and that knowledge of this single layer reality is accessible through variables and experiments involving these variables and a researcher acting as a conductor and not a constructor of knowledge. Subjectivism is the exact opposite: knowledge of reality does not exist independently of the mind therefore knowledge is constructed and not discovered; knowledge is attained through the idea that there is more than a single layer to reality; and therefore knowledge of reality is obtained through understanding and exploring people situated within that reality via more qualitative methods such as ethnography.


This domain is important to engage with because if we become more engaged with our own philosophical beliefs about reality we can provide a philosophical justification for the research design and indeed for the selection of the phenomenon of interest in some way. This philosophical justification is itself a big subject but it suffices to say that philosophical justifications enable us to better explain and argue the way in which we come to know reality, the way we come to gain knowledge about reality, and the way in which reality is explored in order to gain this knowledge.


My beliefs about reality are based on ontological realism and epistemological subjectivism (relativism), but still working out which exact flavour of each my thoughts align with. But at a general level I do not accept that there is a reality that is fully independent of our minds but at the same time I do not accept that there is a reality that is fully dependent on our minds.



The Philosophy Of Research Design


The philosophical beliefs that we have about reality acts as an input to the research design hence the importance of engaging with our own selves as researchers and our philosophical beliefs.


I have discussed extensively (relatively speaking), and shall continue to do so, about the different philosophies that I have been considering for my research and that I have now selected for the research. Regardless of which philosophies have been selected, it is clear that my philosophical beliefs have guided not only the general selection of a case study grounded theory based research design, but the specific types of case study and grounded theory approaches. It’s important to remember here that there are multiple key writers that have detailed different types of case study and grounded theory approaches situated within different philosophies. Also, away from the key writers there have been other versions of both case study and grounded theory developed, and there will no doubt continue to be different versions developed, led by particular philosophical beliefs.


My own philosophical justification for using case study and grounded theory and the way in which they are being used is being guided by realism and relativism, but without a strict adherence to absolute realism and absolute relativism. These philosophical thoughts are being continuously thought about and explored. It is a substantial area of discussion and debate.



The Philosophy Of The Phenomenon Of Interest


This is a new consideration that I have come across recently and needs more elaboration and exploration before I can begin to define any definite ways in which the phenomenon is being perceived philosophically. But to explain briefly, in general and not specific to my research there appears to be learning processes and sub-learning processes, which can be categorised as either individual learner based, or collaborative or group based. There are many of these processes: it would be fairly easy to develop a Ph.D. proposal based on just a single learning process or sub-process nevermind an actual category, once you were aware of the literature and existing problems!


What I am considering at the moment, and again I can make no commitment to any actual statements of knowing about this area, is the relationship between my own philosophical perspectives of the learning process as I am coding and exploring these processes, and the philosophical perspectives that the research participants might have taken in their demonstration of learning processes. Here we can branch out into many different directions because the philosophical considerations of these processes go right back to Ancient Greece where the likes of Socrates and Aristotle defined certain processes in an absolute and certain way: that learners could engage with their learning in an absolute and certain way. Contemporary philosophers consider more uncertain and relativist approaches to engagement with learning processes and its impact on, for example, the construction of knowledge within learning contexts.


But there are many social and cognitive processes of learning, and whilst there have been much written on these processes there is much that is still to be written and discovered about them. The philosophy of the learning process is something that I have come across recently and still elaborating ideas on and reading about therefore I cannot at this time put forward any detailed arguments of the way in which I am viewing learning processes.



Domain Interconnection


My thoughts on the interconnections between the aforementioned domains, like my thoughts on the philosophy of learning processes, are in their early exploration and development stages. However, early indications show that there is a relationship between these three domains of philosophical considerations, there just needs to be further explorations and readings into what exactly this relationship is, what it entails, what it impacts, and what conditions are required for a relationship and different types of such relationships to exist.


Are my philosophical beliefs of reality providing an impact not just on the development of the research design, but also the way in which I perceive or view the learning processes?


Are my philosophical beliefs influencing the way in which I perceive participant approaches and perspectives of their learning processes?


Could a mismatch exist between the way that I perceive demonstrated learning processes, and the way in which participants perceive them?


Is there ultimately an ideal way in which learning processes should be perceived philosophically?


These are just few of the questions that I have with regards to this incredibly complex and challenging area of thinking and development, but it is worthwhile engaging with your own beliefs and engage with plenty of reading in order to develop and fully elaborate on a philosophical justification or serious of justifications as to why you are doing what you are doing. It is worthwhile engaging with your own beliefs as you can fit your research and yourself within the domains of philosophical considerations. A challenging area, but a worthwhile investment!

Reintroducing Grounded Theory As The Research Methodology!

The mixed methods methodology has been dropped due to reasons outlined in the previous blog post. I am now taking the research back to my original idea of using just a grounded theory approach, underpinned by guidance from Strauss and Corbin along with possibly other authors as time progresses but this shall be determined in time. What does this mean exactly for my research? What does this change of methodology mean now? Changes might now occur at three different levels:


Philosophical level

A philosophical question now is whether or not I can proceed with the research using a critical realist philosophy. This will need a great deal of thought beyond the second upgrade paper, but at the moment I am not sure. The idea of critical realism is that ontologically there are events and activities that occur outside of our own thinking and perceiving of them, whilst epistemologically our understanding of these events and activities are continuously fallible and we can never really fully know the truth behind, for example, a process, and why a process occurs.


Perhaps using multiple observations or “cases” of phenomena along with using other methods contained within a grounded theory analysis could promote a critical realist perspective, because whilst the researcher is allowed under grounded theory to generate their thoughts and theorising during coding ultimately all thoughts must be grounded within the data. The theory emerges not from our thoughts and thinking, and perceiving, but from the grounded theory data. A question here though is that it could still be subjective: my grounding of my own thoughts and thinking within the data could still simply be based on the way in which I interpret the data. If this is a case, are there any events and activities that occur outside of our perceiving or thinking of them? If so, what? And how, and why?


Critical realism’s ontology is based on post positivism or empiricism; epistemologically, it subscribes to interpretivism or relativism. Is this really the right way? Do I have to rethink the ontological and epistemological aspects? I am not totally sure at this time; however, philosophically speaking grounded theory is somewhat pragmatic in that it can neatly fit within near any philosophical orientation as long as this is fully understood and justified.


Lots of questions have risen since the trial study particularly with regards to the relationship between the researcher and the participant. From what I can currently understand, philosophical orientations describe the relationship between the researcher and the participant, but what about relationships between researcher and the data where there is a sense of detachment between researcher and participant? What then? Challenging, but exciting, and will be exploring this much more.



Methodological level


Obvious and clear changes: the mixed methods methodology has been dropped. The research design is now based on a grounded theory approach possibly centred on critical realism. I am not sure about adopting a full case study approach due to analytical incompatibilities between case study, critical realism, and grounded theory, but this might be something that I shall have to revisit in the future. It is possible to do a grounded theory within a case study, but then critical realism would have to be dropped.


The methodology now is grounded theory based on principles from Strauss and Corbin and perhaps other grounded theory authors. Potentially, some amendments might be made to grounded theory in order to represent the exact context of the research. These amendments might be based on resolving the philosophical issues some of which have been outlined in the previous section.


A question that has come to me due to potential philosophical issues is deciding whether or not qualitative is the correct term to use to describe grounded theory, because of the relationship between the researcher, the participant and the grounded theory data. This is something that I shall be exploring further.


Practical Level


In more practical terms, the change of methodology will enable me to focus on mastering a single methodology, a single set of methods within grounded theory methodology, and be able to channel my thoughts towards resolving existing philosophical issues either in general, specific to the context of my work, or a mixture of both. Not to mention being able to fully comprehend and propose ways in which existing reliability and validity issues can be resolved.


Placing grounded theory at the level of methodology was the original proposal before I latched onto mixed methods methodology. But interestingly I did not realise or was aware of the practical benefits of using only a grounded theory approach for my research, but now I do realise these benefits, and therefore happy to drop the mixed methods approach.


A key feature of my previous methodology was theory testing and refinement through the use of quantitative findings. This might still occur within qualitative grounded theory through ideas based on theoretical sampling method in order to test the emerging theory, and also use constant comparisons between each case in order to identify similarities and important differences in order to refine the theory. However, should these really be classed as approaches to theory refinement, or simply refining the validity and reliability of qualitative, grounded theory findings?

Summary


Plenty of philosophical and methodological challenges are no doubt ahead, but my passion and enthusiasm of philosophy and of grounded theory methodology will no doubt be able to carry me through, resolving any problems that come along, and form solutions that are workable, practical, and lead onto contributing new knowledge and understanding of resolving existing problems that have not yet been resolved, or even identified in the first place.


Highlighted Problems With The Questionnaire Approach

A while after the submission of the original upgrade paper, I had concerns about my own methodological approach. The sequential exploratory mixed methods design, which I thought was faultless, was being questioned by my own thoughts and increasing awareness of potential problems. The concerns that were raised and discussed with regards to the questionnaire approach were as follows:


Response Rate


Literature shows that response rates to online questionnaires, no matter their quality, is usually fairly low and usually does not meet the requirements of the researcher or the general requirements to reach data levels needed to produce a quality set of results and a quality set of insights based on these results. I did express my concerns about not reaching these levels and I did say that if I did not reach the required levels I would be disappointed. On this fact alone the assessors advised me to drop the questionnaire approach and just use the grounded theory approach as I would be able to attain and analyse much more data.


Precisely Measuring Phenomena


Construct validity is a key issue in questionnaire design. Given that new insights have been found after the submission of the upgrade paper questions were being asked from myself about whether or not I could really capture what I really wanted to capture. Could the questionnaire capture all that I really wanted to capture? Would it be even able to measure what I want to measure? The problem I had at the upgrade presentation was I could not present a questionnaire nor give much in the way of what could be on the questionnaire because the entire design would be based the findings of grounded theory. This point was appreciated. But even so, even if it were not mentioned I would have still had my own concerns of my own approaches.


Time


This wasn’t mentioned at the presentation, but a key issue here is time. It takes time to develop a grounded theory, convert it into a format suitable for the development of the questionnaire, trial and deploy the questionnaire, wait for the appropriate responses, and then analyse the data using various appropriate quantitative measurements. Not to mention writing an eighty thousand word thesis and writing various conference and research papers in between all that. Again although this wasn’t mentioned, I do wonder if time factored into the advice to drop the mixed methods approach and stay with grounded theory.



Overall


Sometimes I wonder if there really was a secret message underneath all this. Something along the lines of, “listen, we know you are enthusiastic about this and we don’t doubt your ability to do what you propose but you have to think about the practical aspects such as time, and whether or not you can do everything that you plan to do within the time allocated to complete a Ph.D.” Which is, obviously, a fair assessment to make as I was questioning myself about the element of time. It’s all fine and dandy producing a research design that is workable, but really pointless in an administrative sense if it cannot be completed within the allocated time and also if there is a chance that some aspects of the Ph.D. could remain uncompleted at the time of the need to write the rest of the thesis.


Perhaps a sequential, exploratory mixed methods approach would take too long to do for a Ph.D. project; perhaps sometimes playing it “safe” is the best option. I say “safe” in quotation marks because whilst the approach might appear to be safe in terms of own ability to do the work in the allotted time, it doesn’t mean that it’ll be easy!

All Case Study Aspects Dropped: the case, pun intended, for this

Ok, after much deliberation I have decided to drop all case study elements from my research. Debates and discussions regarding the inclusion of case study elements within a mixed methods context utalising grounded theory vary widely. But for me the case study approach goes against the nature of the research and the research intentions even if it were used for only framing the research questions and the data collection and analysis procedures, because quite frankly relevant approaches from critical realism, mixed methods and grounded theory appear to encompass all that is required, making the case-based study or strategy rather redundant. Despite numerous reasons for being initially attracted to case study aspects e.g., exploration of phenomenon in its natural setting and the carrying out of an intensive and detailed study on a phenomenon, the five key deciders for dropping any mention of a case study are discussed. Note that what is discussed has come not from actually carrying out case study research, but from logic and reason based on my current understanding.


Theoretical incompatibility


Intentions of my research are to develop theory from the grounded theory data within the quantitative strand, test the theory using the quantitative strand, and then use the quantitative data to refine the theory. Case study emphasises not the development of theory, according to key authors Eisenhardt and Yin, but the testing of a theoretical framework, either existing or developed through the analysis of literature, before commencing any case study research.


The emphasis on the theory development through literature and prior to carrying out the research is incompatible with grounded theory, which suggests that an existing theoretical framework should not be forced onto the data but emerge and develop from the data. I accept however that there are theses out there that have not developed a theory prior to carrying out a mixed methods case study, but for me and the intentions of my research that approach would not work.


Additionally, I am unsure of case study’s stance on theory refinement. Plentiful literature describes it as an effective strategy or methodology, depending on the way it is used, for theory development, but nothing on actual theory refinement.


Sampling Incompatibility


From my understanding, everything needs to be designed, developed and explored relevant to the case or a series of cases. Whilst case study research employs a form of purposive sampling of cases, it appears to me that all participants of a particular case must be included in the research with no "outsiders". Whilst this is fine if that is the intention, the mixed methods approach being developed for my research requires different population samples from outside of the cases that shall be explored, and this does not appear to fit within the use of sampling for a case study. If I were to use a sequential explanatory mixed methods this would not be an issue, but because I am developing a sequential exploratory, an amended version, this would be a problem. A problem would involve the fact that the theory would be tested on a population sample different to the participants of the cases explored through grounded theory. The fact the samples shall differ between qualitative and quantitative makes case study incompatible.



Non-Triangulated research


Case study actively encourages triangulation of research findings, meaning that the findings come from different research methods for a variety of purposes including corroborating data and improving research validity. The concurrent triangulation variation of mixed methods was going to be used until it was realised that this would have led to difficulties in the research design and therefore render it unreliable, therefore it was switched to a sequential exploratory approach. Concurrent triangulation would have achieved the triangulation objective of the case study approach, but the sequential exploratory does not: at least, not the in the way it is being used in this research to develop a theory.



Replication Logic


Replication logic is what gives case study a mode of generalisability or in other words the ability to generalise identified events and activities across a series of cases. Replication appears on two levels: literal replication if few cases are explored and theoretical replication if several are selected. The former is used for predicting similar results across cases whilst the latter is used for predicting contrasting results across cases but for reasons that can be anticipated. Yin’s description of replication logic is akin to experimental designs: the focus is on replicating findings in some way, and therefore highlights a positivist approach to research, which would in my opinion oppose the general philosophical stance of grounded theory. Grounded theory is a mode of interpreting data and is therefore not a mode of enforcing a particular theoretical framework upon data in order to find some sort of replication. There is a form of replication that can be found within grounded theory, but this does not come from an enforcement of a theoretical perspective but is allowed to emerge naturally from the data relative to the perspectives and interpretations of the researcher.


Therefore, replication logic appears to be based on replication based on pre-existing theoretical frameworks and assumptions. This is unlikely to work in my research.

Well then!


No, no, I am not going to say that the sequential exploratory mixed methods using grounded theory and questionnaire (more than likely: depends on the findings of the grounded theory) underpinned by critical realism shall be the research design because I might change my mind, but it’s not likely though I have said that before! But that’s the beauty of research: you can never really be certain or absolute of anything.


All of my latest ideas about the research design is to be confirmed as appropriate by the supervisor.

Case study? Case–based strategy? Not a case–based strategy? What is it then?

Remember the time I posted up a post that began with remember the time when I said that my research design is complete? I’m saying it again: remember the time when I said that my research design is complete? Well, earlier in the day a thought literally struck my ideas of a case study down, stamped all over them, and performed some sort of war dance over them chanting in some intelligible language. So, I will not dance about and sing claiming that I have found my research design because, given that I am a critical realist, to claim that I have found an absolute research design would be complete and utter nonsense.


Regardless, the intention was never to implement a full case study design as the research uses a particular variant of the mixed methods methodology. Whilst mixed methods can be used within a case study design, I have come to realise that the type of mixed methods that I am proposing (an amended version of Creswell’s sequential exploratory to reflect better the theory refinement phase) and the types of methods being used is making me question the use and role of a case study approach.


So I began thinking about the idea of calling case implementation a case-based strategy for framing the research questions and acting as a general guide for guiding the mixed methods data collection and analysis sequences, but it was realised that this didn’t really make much sense because it would only apply to the qualitative aspect and not the quantitative aspect, and also from what I understand all phases of a sequential mixed methods approach would have to study the same participants because it is about studying a single case e.g., a group of people, an organisation and so on. Sequential exploratory calls for different population samples, though sharing the same basic characteristics, for both qualitative and quantitative strands.


A key question that has been playing on my mind is, is it really the right way to call something a case study or even a case study strategy if some of the key aspects of such an approach are not going to be utalised? Can you really mould and combine bits of different methodologies and methods and call it by a particular name e.g., is it really right to call my study an exploratory mixed methods case study on X phenomenon if most of the key functions of a case study shall not be used?


If not, then what can I call it? What does it all even mean?

Case-based?


Could my research be case-based? There are clear examples of cases existing, with a case being defined as simply an instance of a phenomenon of interest e.g., I am exploring a particular process of learning so a case would simply be defined as a separate but related instance of this phenomenon. In terms of Education think of a “case” as a classroom, or an individual student, or a group of learners.


A discussion on the academic site ResearcherGate included a comment suggesting that within a sequential mixed methods design, a case study can be used as part of the qualitative component but because my research design has been amended slightly to reflect theory refinement, it kind of goes beyond the limit of what a case study is supposed to achieve, in my opinion from what I can currently understand. Another debate revolves around if whether or not aspects of case study can really be used within a grounded theory exploration, and opinions on this appear to vary widely with some supporters of this idea whilst former Ph.D. candidates stated that their examiners were critical of this approach. An interesting comment suggests that if an approach uses an existing theoretical framework upon the data then it is difficult to call this grounded theory, because all versions of grounded theory does not work strictly within a theoretical framework. The commentator suggests that if a project contains more case study principles than grounded theory principles then it would be incorrect to call it a grounded theory study, which makes sense. If on the other hand, as another commentator alluded, and as my research appears to be leaning towards, the project contains more grounded theory elements than case study elements then it would be wrong to call that something like a case study grounded theory project, because it would not be adhering to case study principles.


So perhaps I have to think of my research in terms of it being case-based, and not actually call it a case study or even a case strategy. Interestingly I have just read a research paper that states that studying cases is not exclusive to case study research, but can be present in all approaches that adhere to qualitative assumptions and this includes grounded theory.


Ultimately, is there really a need for any reference to case study or case strategy if all what I need in reference to studying instances (cases?) qualitatively resides within a grounded theory approach?


Something to think about!

Slightly Amended Research Design

Since the research methodology chapter of the thesis is going to be around ten thousand to fifteen thousand words, it’s impossible to really explain all aspects of the research design in a blog post of less than a thousand words. Firstly because I’ll probably bore people to the point they would rather listen to One Direction, and secondly because understanding the relationship between all the components is a continuous and ongoing task.


The mixed methods variety has changed and the research is now encapsulated within a case study approach. The research design is now a critical realist multiple-case based sequential exploratory mixed methods design. So, why the change? The change came about through a conversation with the supervisor and the progress of the trial study.



Sequential Exploratory Mixed Methods

The trial study, as indicated in the previous blog post, has been and still is a serious, reflective exercise of the research activity and the research design. The previous preferred mixed methods flavour was concurrent triangulation meaning that the questionnaire data collection and analysis and grounded theory analysis would have been carried out at the same time, or concurrently.

This proved to be problematic during the trial study as it became apparent that the emerging theory’s constructs would not have been testable or explored further using the quantitative instrument. Why is this? Because the concurrent nature would have meant the construction of the questionnaire occurring before quantitative and qualitative data collection and analysis, leaving no room for further amendments to it. This would have led to the research being susceptible to validity problems and potential gaps in the theory therefore the theory’s integrity, relevance, completeness and even generalisability would have been questioned. After returning to the research methodological literature (Ph.D. potentials reading this will come to know the iterative nature of the Ph.D.) I found that the sequential exploratory approach to be more suitable.

The sequential exploratory variety of mixed methods involves the qualitative phase occurring first therefore the grounded theory method shall be used to generate an emerging, developing theory from the data. The constructs that emerge from the data shall then be converted to a format suitable for development of a quantitative instrument (likely to be a questionnaire) and then the third phase shall be the quantitative phase where aspects of the theory shall be tested for generalisability across different contexts. This solves the identified problem therefore the quantitative instrument shall take into account constructs found in the literature along with constructs built from the grounded theory data, with in some cases both sets being used to support each other with regards to evidencing the need to explore certain constructs further.



Case Study

A case study has been defined in so many ways and can be used in various ways such as either a strategy or as a methodology. A case study enables the researcher to explore a particular case, or multiple cases, in substantial detail hence it is suitable for mixed methods research, in order to generate significant understanding of the phenomenon of interest. It is the depth of detail the case study brings to the research that makes it an attractive option. It is not usually famed for allowing generalisability of data but this is determined by the type of case study that is being used. Multiple-case study using mixed methods enables more of a generalizable approach to be considered.

For this research, case study shall be used as a general strategy for guiding the quantitative and qualitative phases of the mixed methods and their respective methods, whilst the case study strategy is being guided by critical realism.


This research shall adopt the variety known as a multiple-case study, which means that multiple cases or instances of the similar activity shall be explored using grounded theory (hence, a relationship between case study and grounded theory) in order to increase the validity of the findings, with the selection of the cases being determined by the findings of the first case. The multiple-case study has been deemed as appropriate given the nature of grounded theory’s approach towards sampling of data, and given the depth of detail that case study allows.


Summary thoughts

The blog post doesn’t do the research design justice, as for example I have only lightly touched on the relationship between critical realism, case study, mixed methods, and grounded theory. Understanding this relationship between the different components is ongoing and progressing and will be explained more in the upgrade paper and fully elaborated in the thesis. But it is enough on here to say that I am convinced that these amendments to the research are correct and the way that the design should be. But I must not have the mindset where I am absolutely sure that the research design is correct as it has to pass the upgrade assessment panel later this year.

It’s been challenging working towards the research design, but it’s been a rewarding experience. A key activity at this time is to further understand the relationship between critical realism, case study, mixed methods and grounded theory, and that is no easy feat.


So, the research design shall not change! Till next time, that is!

Research update

Been quite a while since I have written a blog post on here as there have been plenty of things going on to distract me, but now is time for a series of blog updates! The following is a brief overview of the key areas of activity, with further blog posts following that explore these in more detail.



Update on the Trial study


The trial study is based on trialling a collaborative activity and trialling a grounded theory approach adapted from the ideas of Strauss and Corbin. I say adapted because there are a variety of authors suggesting Strauss and Corbin’s version is too regimented and difficult to follow, but Strauss and Corbin did respond by suggesting their procedures for coding do not have to be followed through strictly, therefore researchers should logically and constructively apply grounded theory procedures relevant to the research context. I might alter aspects of the approach as the trail and the main thesis study continues.


The trial appears to be coming along well. As reported in earlier posts I managed to successfully carry out the trail activity so it is now the case of continuing to use grounded theory to learn about it more, and to learn about the data that I have collected. I am fascinated with grounded theory! Lots of information on grounded theory online but for now it suffices to say that grounded theory is a key methodology (or method: it can be viewed both ways depending on its purpose and position within the research design) in developing new conceptualisations, a new theory, or new theorising of the phenomenon of interest. This is challenging and I have the belief that in order to really be successful at this you have to be quite creative and able to think about data, events, observations and aspects of reality at an abstract level. You begin with exploring the data but you have to think about the data at a higher, abstract level. It’s about interpreting the data based on your observations, though the validity of these interpretations can be increased depending on the research design and the way in which existing literature is used. But despite it being challenging it is an exciting approach to exploring data.



Trial Study as the Thesis Study


The most significant feedback and conversations during the past month or so has been the idea of using the trail study as a thesis study, or acting as a case within the thesis study. This was and still is huge, because it effectively means that when I am exploring and coding the data not only am I exploring data to benefit the production of the upgrade paper but also to benefit the thesis and the research itself. This has been deemed feasible therefore I shall be using the activity as part of the thesis and also explore other activities, known in the thesis as cases, in order to locate differences and similarities, which shall increase the validity of the theorising and theory development.



Change of Research Design


This change has actually come about through working through the trial study. Previously I had mentioned about adopting a critical realist, concurrent triangulation variety of mixed methods where the quantitative and qualitative aspects of the study would be carried out at the same time. In other words, I would have been carrying out grounded theory analysis of the activity whilst collecting thoughts and beliefs of the learners at the same time and then integrate the findings and discussions.


The only aspect that has changed is the mixed methods variety: I’ve ditched the concurrent triangulation and adopted the sequential, exploratory variety. Briefly, during the trail study I was struggling with the way in which data from the grounded theory findings and questionnaire findings could merge due to the abstractness of grounded theory. There would have been a chance of new concepts and new conceptualisations emerging from the data but exploring them via quantitative measures would not have been possible because the quantitative phase would have started at the same time, or in other words concurrently.


Using a sequential exploratory approach enables the constructions and conceptualisations, the theory, to emerge first and then test these out using the questionnaire and generalise across a wider population. This makes a lot more sense than to carry out both threads concurrently given the potential for extra insights that would not have been possible to explore had the mixed methods approach remained unchanged.


I’ve also encapsulated the research into a multiple case study, therefore the research design is now a critical realist multiple case based sequential exploratory mixed methods design.



Progress on the Upgrade Paper


This has been rewritten more times than I care to remember and will be reread and edited in various places before actually handing it in. When I rewrite each section I ask myself why did I not think about things in a particular way and communicate in a particular way before. But that is the beauty of re editing: it makes you think and contemplate more as you go through the document and think if you can explain anything in a more concise, or more sophisticated way without dropping the meaning behind the text. I know this, but still, sometimes it takes me by surprise at the differences that are found between each modified version of a particular document.


Most of the sections are now complete. Only sections that need to be completed are the trial study section, and talk a bit more about potential problems and possible outcomes.

That’s the brief overview of the main things that have been going on during the past month or so!

Rambling load of updates!

Research Design


The components of the research design were decided a few weeks ago and the components are now unlikely to change. The research design is based on a critical realist approach to a convergent paralleled variety of mixed methods, which includes the use of a questionnaire and grounded theory methods based on the Strauss and Corbin version. I did go through a phase of feeling overwhelmed a few weeks ago as I had decided to change the grounded theory method component, which spurred a huge quantity of questions and thoughts about compatibility and research design validity all at once. I think reflecting back I had become so convinced that Charmaz’s Constructivist Grounded Theory would work, till the philosophical stance changed from relativism to critical realism, that the need to change the grounded theory method was impactful on my confidence of the research design and my overall ability to understand it all. But with patience, time, careful thinking and further reading my confidence in the validity and feasibility of the research design is growing.


This is not to say however that I know everything about the research design components and I do not actually know that the research design will take off. However, at the moment I am meticulously and comprehensively studying each of the research design components and threading them together to make a complete, compatible research design that is relevant to the research context and phenomena of interest. This is being achieved through constructing arguments for the need of the research design within the specific context and relevance for the phenomena of interest, and also through building critiques of existing research designs and relevant design components within Educational research, particularly relevant to the phenomena of interest. This is a current, ongoing task with argumentation and critiques continuously being constructed and amended in various ways through reading relevant literature and thinking about this literature.


Upgrade Paper


Coming along nicely though I shall be dealing with a few questions at the next meeting with the supervisor, including questions regarding the methodological section: is it best to focus on describing the process of the research design? E.g., describe critical realism in a way that is relevant to explaining the process of mixed methods then explain the process of mixed methods and so on. Or is it best to focus on argumentation of the research design? Or a mixture of both?


First draft should be completed soon. The sections have been figured out, so now it’s a case of completing the sections and then begin the process of editing. This is an ongoing process.


Trial study


Decided to let an aspect of the trial period run on for a while longer than previously planned, just to find out what would happen further with the trial and I am pleased that I made this choice because I now have more than enough data to build a practical understanding of the qualitative analytical research methods relating to grounded theory. Additionally, I wonder if there is merit in using the data from trial period in the actual research study, given that grounded theory has an “all is data” perspective. It would be interesting if I could use this data, because that would give me a start on theorising from the codes and categories generated from the data, as described by grounded theory.

Questionnaire is yet to be trialled, but this will happen in the future. This shouldn’t take too long, as all that is required is to trial the design, think about possible statistical analysis methods, then trial the analysis methods, and then think about the way in which quantitative and qualitative data can be analysed to complement or converge with each other. Oh, not too much to do then!


Summary


So that’s about it, but enough to get on with! In summary, the immediate tasks are: continue to thread the research design together through argumentation, critique of existing research, and experimenting with the design theoretically and practically; continue with the upgrade paper, and continue with the trial study through trialling the grounded theory methods, and the questionnaire.
