4. What is research?
• “A studious inquiry or examination,
especially a critical investigation or
experimentation having for its aim the
discovery of new facts and their correct
interpretation, the revision of accepted
conclusions, theories, or laws in the light
of new discovered facts or the practical
application of such conclusions, theories
or laws.”
• “Diligent and systematic inquiry or
investigation into a subject in order to
discover facts or principles.”

5. What is a paradigm?
 A broad framework of perception, understanding,
belief within which theories and practices operate.
 … a network of coherent ideas about the nature of
the world and the functions of researchers which,
adhered to by a group of researchers, conditions
their thinking and underpins their research actions
[Bassey, 1990: para 8.1]
 A basis for comprehension, for interpreting social
reality [Cohen, Manion & Morrison, 2000: 9]

6. What is a paradigm? (Continued)
 It pre-structures perceptions, conceptualisation &
understanding
 Shifts in scientific theory require new paradigms
[Science is] …a series of peaceful interludes
punctuated by intellectually violent revolutions …
in which one conceptual world view is replaced by
another. [Cohen, Manion & Morrison, 2000: 396]
 Researchers from different disciplines
[traditions?] may have different paradigms
 There are competing paradigms in education
research

7. Synoptic View of PARADIGM ?
 a mental model
 a way of seeing
 a filter for one's perceptions
 a frame of reference
 a framework of thought or beliefs through
which one's world or reality is interpreted
 an example used to define a phenomenon
 a commonly held belief among a group of
people, such as scientists of a given discipline

8. Paradigm Shift
 In 1962, Thomas Kuhn wrote The Structure of
Scientific Revolution, and fathered, defined and
popularized the concept of "paradigm shift" (p.10).
Kuhn argues that scientific advancement is not
evolutionary, but rather is a "series of peaceful
interludes punctuated by intellectually violent
revolutions", and in those revolutions "one conceptual
world view is replaced by another".
 Think of a Paradigm Shift as a change from one way
of thinking to another. It's a revolution, a
transformation, a sort of metamorphosis. It just does
not happen, but rather it is driven by agents of change.

10. Main Components
of a Paradigm:
(Ontology, Epistemology,
Methodology)

11. Main Components of Paradigm
 ‘Epistemology – „The branch of
philosophy concerned with the
origin, nature, methods & limits of
knowledge‟
 Ontology – „concerned with being‟ or
reality.

12. Ontology
 Ontology is the starting point of all
research, after which one‟s
epistemological and methodological
positions logically follow. A dictionary
definition of the term may describe it
as the image of social reality upon
which a theory is based

13. Ontology
 Norman Blaikie offers a fuller definition,
suggesting that ontological claims are
„claims and assumptions that are made
about the nature of social reality, claims
about what exists, what it looks like, what
units make it up and how these units
interact with each other.
 In short, ontological assumptions are
concerned with what we believe constitutes
social reality‟ (Blaikie, 2000, p. 8)

14. Epistemology
 Epistemology, one of the core branches of
philosophy, is concerned with the theory of
knowledge, especially in regard to its
methods, validation and „the possible ways
of gaining knowledge of social reality,
whatever it is understood to be.
 In short, claims about how what is
assumed to exist can be known‟ (Blaikie,
2000, p. 8).

15. Epistemology
Derived from the Greek words episteme
(knowledge) and logos (reason), epistemology
focuses on the knowledge-gathering process and
is concerned with developing new models or
theories that are better than competing models
and theories.
Knowledge, and the ways of discovering it, is not
static, but forever changing. When reflecting on
theories, and concepts in general, researchers
need to reflect on the assumptions on which they
are based and where they originate from in the
first place.

16. Ways of Knowing about the
World: Inquiry Strategies
•Authority (parents, state, boss, etc)
•Religion (faith, belief, standard, morals, etc)
•Tradition (we have always done that way, folkways,
cultural patterns, we know how to behave in
certain situation)
•Intuition
•Creativity
•Science and scientific research

17. Research Methods and
Methodology
Methodology refers to general principles
which underline how we investigate the
social world and how we demonstrate that
the knowledge generated is valid.
Research methods refers to the more
practical issues of choosing an appropriate
research design – perhaps an experiment or
a survey – to answer a research question,
and then designing instruments to generate
data.

23. Logic of Inquiry: Research
Strategies

24. Induction
The Inductive approach to enquiry builds
generalizations out of observations of specific
events. It starts with singular or particular
statements and ends up with general or universal
propositions.
It presupposes that explanations about the
workings of the world should be based on facts
gained from pure, dispassionate and neutral
observation, rather than on preconceived notions;
that nature will reveal itself to a passively receptive
mind.

25. Induction (Continued)
The Inductive strategy assumes that all science starts with
observations which provide a secure basis from which
knowledge can be derived and claims that reality impinges
directly on the senses, hence there is a correspondence
between sensory experiences, albeit extended by
instrumentation, and the objects of those experiences. The
conclusion of an inductive argument makes claims that
exceed what is contained in the premises and so promises
to extend knowledge by going beyond actual experience.
The more observations that demonstrate, say, a
relationship between phenomena, the higher the probability
that the general statement is true. Verification of derived
generalizations comes through observations about
particular phenomena that appear to support it.

26. Induction (Continued)
Critics of this approach claim that: it is essentially
descriptive and does not really explain anything
as it fails to uncover the causes of the
generalized conjunctions; there is no purely
logical inductive process for establishing the
validity of universal statements from a set of
singular ones; it is impossible to make the infinite
number of observations required to prove the
universal statement true in all cases and; is
objectivity possible when observations and their
analysis are made by people who have some view
of the world arising out of their particular
discipline?

27. Inductive Thinking

28. Deduction
The Deductive (hypothetico-deductive or
falsificationist) approach is the reverse of
an Inductive one. It begins explicitly with a
tentative hypothesis or set of hypotheses
that form a theory which could provide a
possible answer or explanation for a
particular problem, then proceeds to use
observations to rigorously test the
hypotheses.

29. The Deductive argument moves from
premises, at least one of which is a
general or universal statement, to a
conclusion that is a singular statement.
Deductive propositions form a hierarchy
from theoretical to observational; from
abstract to concrete. The Deductivist
accepts that observation is guided and
presupposed by the theory.

30. Deduction (continued)
Attempts are made to refute the hypotheses
through rigorous criticism and testing. If the
data derived by testing the hypothesis is not
consistent with the predicted conclusions, the
theory must be false. Surviving theories are
corroborated, but are never proved true despite
withstanding testing and observation. A current
theory is superior to its predecessors only
because it has withstood tests which falsified
its predecessor.

31. Deduction (continued)
Critics of this approach claim that:
• where a theory has not been falsified, its acceptance relies
on data that lend 'inductive support';
• Deductivists are reluctant to deal with the process by
which hypotheses come into being;
• whether Deductivism provides any rational basis for
choosing between all un-refuted alternative theories in
order to make some practical prediction.
• The Inductivist position is that the truth of theories could
be conclusively established.
• The Deductivist position claims that while the pursuit of
truth is the goal of science, all scientific theories are
tentative.
• Neither Induction or Deduction contributes a single new
concept or new idea.

32. Deductive Thinking

34. The Research Wheel

37. Combined approach:
A scheme has been proposed by Wallace
(1971) that combines Inductive and
Deductive strategies to capitalize on their
strengths and minimize their weaknesses
creating a cyclic process that allows for
movement between theorizing and doing
empirical research while using both
Inductive and Deductive methods of
reasoning.

38. Retroduction
Retroductive research strategy involves the building of
hypothetical models as a way of uncovering the real
structures and mechanisms which are assumed to
produce empirical phenomena. The model, if it were to
exist and act in the postulated way, would therefore
account for the phenomena in question. In constructing
these models of mechanisms that have usually never
been observed, ideas may be borrowed from known
structures and mechanisms in other fields.
A phenomena or range of phenomena is identified,
explanations based on the postulated existence of a
generative mechanism are constructed and empirically
tested, and this mechanism then becomes the
phenomenon to be explained and the cycle repeats. p168

39. Retroduction
Pierce regarded Retroduction or 'hypothesis
formulation' as being the first stage of an enquiry. It
is a process akin to finding the right key for the lock,
although the key may never have been observed
before.
The hypothesis must be tested using both
Deduction and Induction; in the second stage of an
enquiry, consequences are deducted from the
hypothesis and, in the third stage, these
consequences are tested by means of Induction. He
suggested that a hypothesis must eliminate
puzzlement as a necessary first step.

40. Retroduction/Abduction occurs in the
context of ontological, conceptual and
theoretical assumptions; the researcher
does not start with a blank slate in the
manner implied by Inductivists. Quasi-
accessible mechanisms can be discovered
from empirical studies of an exploratory
kind with input from an associated field of
knowledge in which some process is used
as an analogy for the one under
investigation. p 169

41. Retroduction differs from Induction which infers
from one set of facts, another set of
facts, whereas Retroduction infers from facts of
one kind, to facts of another. Unlike Deductive
reasoning, Inductive and Retroductive reasoning
are synthetic or ampliative because they make
claims that do not follow logically from the
premises. In addition, neither Induction nor
Deduction can produce any new ideas. On the
other hand, Retroductive/Abductive reasoning
involves making an hypothesis which appears to
explain what has been observed; it is observing
some phenomenon and then claiming what it was
that gave rise to it.

42. Abduction
The Abductive research strategy is used by
Interpretivism to produce scientific accounts of
social life by drawing on the concepts and
meanings used by social actors and the activities in
which they engage.
Access to any social world is by the accounts given
by the people who inhabit it. These accounts
contain the concepts that people use to structure
their world - the meanings and interpretations, the
motives and intentions which people use in their
everyday lives and which direct their behavior.

43. Abduction/Interpretivism acknowledges that human
behavior depends on how individuals interpret the
conditions in which they find themselves and
accepts that it is essential to have a description of
the social world on its own terms. It is the task of
the social scientist to discover and describe this
world from an 'insider' view and not impose an
'outsider' view.
A position taken by Douglas rules out experimental
situations. Everyday life is studied in its own terms
- the members' understanding, and only methods of
observation and analysis that retain the integrity of
the phenomena should be used.

44. Abduction is applied when attempting to move
from lay accounts of everyday life, to technical,
scientific or expert descriptions of that social
life. p 177
Abduction is a developing strategy with on-
going debate on how best to move from lay
language to technical language. There are
differences of opinion with regard to retaining
the integrity of the phenomena when moving
first order constructs (people's views and
explanations), to second order constructs (the
social scientist's interpretations).

45. The Abductive strategy has many layers to it. There is
some difficulty in preceding to the final stage in which
social theories might be generated from the second order
constructs or that these social scientific descriptions can
be understood in terms of prevailing social theories and
perspectives, leading to the possibility of an explanation
or a prediction.
Some positions argue that the research should go no
further than to sort through, devise categories for and
pigeon hole the various constructs provided by the social
actors within the study.
The Abductive/Interpretivist approach has been advocated
as either the only approach for social sciences, or an
adjunct to other strategies.

46. Positivism, Critical Theory et. al,
Interpretivism/Constructivism:
A Comparison Among Paradigms

47. Positivism
Quantitative purists (Positivists):
 Believe that social observations should be treated as
entities in much the same way that physical scientists
treat physical phenomena.
 Contend that the observer is separate from the entities
that are subject to observation.
 Maintain that social science inquiry should be objective.
 That time- and context-free generalizations (Nagel,
1986) are desirable and possible, and
 Real causes of social scientific outcomes can be
determined reliably and validly.

48. Interpretivism / Constructivism
 Qualitative purists (also called constructivists
and interpretivists) reject positivism.
 Argue for the superiority of constructivism,
idealism, relativism, humanism, hermeneutics,
and, sometimes, postmodernism.
 Contend that multiple-constructed realities
abound,
 That time- and context-free generalizations
are neither desirable nor possible,

49. Interpretivism/Constructivism (Cont’d)
 That research is value-bound,
 That it is impossible to differentiate fully
causes and effects,
 That logic flows from specific to general (e.g.,
explanations are generated inductively from
the data), and
 That knower and known cannot be separated
because the subjective knower is the only
source of reality.

50. Understanding Critical Theory
Two Propositions
 1) People are a product of the society in
which they live. Hence this implies that
their is no such thing as an objective fact
that can be known outside of structure.
 2) Intellectuals should not try to be
objective and separate value judgments
from their work

62. Researcher as Bricoleur

63. The Qualitative Researcher as Bricoleur
The multiple methodologies of qualitative
research may be viewed as a bricolage, and
the researcher as bricoleur.
A bricoleur is a “Jack of all trades or a kind
of professional do-it-yourself person”.
The bricoleur produces a bricolage, that is, a
pieced together, close-knit set of practices
that provide solutions to a problem in a
concrete situation.

64. The Qualitative Researcher as Bricoleur
 The solution (bricolage) which is the result
of the bricoleur‟s method is an (emergent)
construction that changes and takes new
forms as different tools, methods, and
techniques are added to the puzzles
 Bricoleur uses the tools of his or her
methodological trade, deploying whatever
strategies, methods or empirical
materials, as are at hand, or invents and
pieces together new tools if needed

65.  The choice of research practices depends
upon the questions that are asked, and
the questions depend on their context:
 The combination of multiple methods,
empirical materials, perspectives and
observers in a single study is best
understood, then, as a strategy that adds
rigor, breadth and depth to any
investigation

66.  The bricoleur is adept at performing a large
number of tasks, ranging from interviewing to
observing, to interpreting personal and
historical documents, to intensive self
reflection and introspection
 The bricoleur reads widely and is
knowledgeable about the many interpretive
paradigms/perspectives (Feminism, Marxism,
Cultural Studies, Constructivism) that can be
brought to any particular problem

67.  He/She may not feel that paradigms can be
mingled or synthesized, that is, paradigms
as overarching philosophical systems
denoting particular anthologies,
epistemologies, and methodologies cannot
be easily moved between.
 They represent belief systems that attach
the user to a particular worldview.
 Perspectives, in contrast, are less well
developed systems, and can be more
easily moved between.

68.  The researcher-as-bricoleur-theorist works
between and within competing and overlapping
perspectives and paradigms.
 Research is an interactive process shaped by
researcher‟s personal history, biography, gender,
social class, race and ethnicity and those of the
people in the setting.
 The bricoleur knows that there is no value-free
science.
 Thus the narratives, or stories, scientists tell are
accounts couched and framed within specific
storytelling traditions often defined as paradigms
(e.g. Positivism, Post-positivism, Constructivism).

69.  He/She knows that researchers all tell stories
about the worlds they have studied
 The product of the bricoleur‟s labor is a
bricolage, a complex dense, reflexive, collage-
like creation that represents the researcher‟s
images, understanding, and interpretation of the
world or phenomenon under analysis.
 This bricolage will connect the parts to the
whole, stressing the meaningful relationships
that operate in the situations and social worlds
studies.
