 A similar trend can be discerned with respect to the long warfare between two rival groups of research methods—on one hand quantitative/statistical approaches to research, and on the other hand the qualitative/ethnographic family. (The choice of labels here is not entirely risk-free, for they have been contested; furthermore the first approach is quite often associated with “experimental” studies, and the latter with “case studies”, but this is an over-simplification.) For several decades these two rival methodological camps were treated by researchers and a few philosophers of education as being rival paradigms (Kuhn’s ideas, albeit in a very loose form, have been influential in the field of educational research), and the dispute between them was commonly referred to as “the paradigm wars”. In essence the issue at stake was epistemological: members of the quantitative/experimental camp believed that only their methods could lead to well-warranted knowledge claims, especially about the causal factors at play in educational phenomena, and on the whole they regarded qualitative methods as lacking in rigor; on the other hand the adherents of qualitative/ethnographic approaches held that the other camp was too “positivistic” and was operating with an inadequate view of causation in human affairs—one that ignored the role of motives and reasons, possession of relevant background knowledge, awareness of cultural norms, and the like. Few if any commentators in the “paradigm wars” suggested that there was anything prohibiting the use of both approaches in the one research program—provided that if both were used, they were used only sequentially or in parallel, for they were underwritten by different epistemologies and hence could not be blended together. But recently the trend has been towards rapprochement, towards the view that the two methodological families are, in fact, compatible and are not at all like paradigms in the Kuhnian sense(s) of the term; the melding of the two approaches is often called “mixed methods research”, and it is growing in popularity. (For more detailed discussion of these “wars” see Howe 2003 and Phillips 2009.)
