Mixed Methods: Post Positivism Is No Longer Considered Appropriate
Description of and arguments against Post Positivism
Post positivism is now no longer among the set of philosophies considered appropriate for my Mixed Methods research due to my stance against philosophies that advocate pure quantitative or qualitative approaches to exploring social reality within educational contexts.
Simply put, post positivism is an extension of positivism; that it still adheres to the main concepts and principles of Positivism but modifies them at the ontological and epistemological levels but mirrors positivism at the methodological level. This modification of the concepts of positivism enables post postivism to accommodate a level of uncertainly, subjectivity, complexity and human experiences therefore recognising that absolute and certain truth about reality is not achievable. Giddings and Grant (2007) called Post Postivism a “lite” version of positivism, stating that the “post” prefix indicates a development or extension of positivism, and offer various examples of the way in which Post Positivism extends the concepts of positivism.
Positivism perceives reality as objective and independent of the mind but post positivism (along with other middle ground Philosophies) suggest that reality is embedded in its own social and cultural contexts and therefore researcher objectivity is impossible to attain. Another key area of divergence is theory verification: positivism emphasises hypothesis testing and theory experimentation in order to prove or disprove them whereas PostPositivists emphasises supporting evidence as a probability rather than being used as an absolute proof. These are just a couple of examples of where positivism and post positivism diverge at the ontological and epistemological levels. However, where they both converge and therefore enables the view of post positivism as being an extension of positivism is that it shares the same methodological assumptions.
Onwuegbuzie et al (2009) (along with many other researchers) confirms this methodological mirroring. Extent of fallibility and defeasibility of absolute knowledge accommodated by post positivism makes inferential statistics usable and applicable through inferential statistics, which utalises probabilistic approaches such as P Vales and Confidence Levels to understand reality. Post positivism also utalises qualitative data, hence post positivists can use Mixed Methods, but they use quantitative approaches to analyse qualitative data. As an example, content analysis is utilised to quantify thematic occurrences through frequency rates, and qualitative data is used in a way that enables the development of more effective quantitative approaches.
In all, post positivism is not a suitable Philosophical perspective for my Mixed Methods research because I am taking the stance that post positivism is not suited to exploring social phenomena and social reality, because everything to do with the social is too chaotic and dynamic to be represented and explained statistically. Post positivism also does not allow for much room in terms of theory building, and theory building or theorising is an aim of my Mixed Methods research as I attempt to theorise the social structures and aspects of reality that influences the phenomenon of interest. I like much of post positivism at the ontological and epistemological levels, but its mirroring of positivism at the methodological level makes it inappropriate for my Mixed Methods research. More discussions shall be found in later blog posts and more especially in my thesis.
So then: the Big Three!
With post positivism no longer being considered appropriate, this now leaves three middle ground philosophies that might be appropriate for my Mixed Methods research: complexity theory, pragmatism and critical realism. From what I have read of these so far, I have issues with pragmatism in that it appears to detach itself from philosophical and methodological concerns and places itself upon the research question. That is, the research question is the most important consideration within pragmatism and therefore all that must be done and used to answer that research question must be carried out. This has left pragmatism open to arguments that suggests it basically allows a free for all design approach with a “what works” attitude that has been questioned by a lot of writers, and I am inclined to agree with the concerns. More on this in future blog posts.
Critical realism and complexity theory appear to be the most attractive middle ground philosophies at the moment as I as yet cannot find any fault with them when it comes to exploring social reality, social phenomena, and assumptions made at the philosophical and methodological levels. Essentially, from what I can currently understand, critical realism does not concern itself with reality as a single, accessible, measurable layer (positivism / post positivism) nor does it concern itself exclusively with human experiences (interpretivism / constructivism) but it concerns itself with the underlying structures and mechanisms that produces what is found at the measurable layer and with human experiences. Now if I have interpreted this correctly, and I appreciate that what I have defined is probably a little lacking in substance but remember I am still learning and exploring this, then this makes critical realism highly applicable for substantial exploration of the social reality. Structures and mechanisms of social reality and their influence on what occurs within this social reality are highly complex and interrelated therefore complexity theory could also play a part in this structural mess.
I do perceive social reality and explorations of social reality to be highly complex and extremely uncertain, and the key to understanding the phenomenon of interest is to consider those underlying structures and mechanisms instead of constantly exploring just what is observable.
Fun stuff isn’t it? It was all a bit scary when I first started exploring Mixed Methods at this level but the more I explore the Philosophy of Mixed Methods the more interesting I find it! Lots to read and think about!
