THINKING ABOUT RESEARCH
AND RESEARCH QUALITY IN
YOUR ACADEMIC WORK.
Presentation for the annual Oxford-Cambridge
Exchange
Pam Sammons and Linda Bakkum
WHAT IS RESEARCH?

Research is a disciplined attempt to address questions or solve problems
through the collection and analysis of primary data for the purpose of
description, explanation, generalization and prediction (Anderson 1998, p 6)

The nature of the subject matter determines what kind of research is valid
or relevant (Pring 2000, p 6)

Reasoning: deductive (Aristotle) formal steps of logic

inductive (Bacon) empirical evidence for verification

Inductive-deductive moving from observations to hypotheses then back to
implications (backwards & forwards).

Subjective belief must be checked against objective reality, research is selfcorrecting.
WHAT IS DISTINCTIVE ABOUT EDUCATIONAL
RESEARCH?
•
The distancing of theory from practice is associated with public and policy
scepticism about value of educational research
•
Need for clarity in defining key terms identified from your literature review
and as used in your study e.g. ‘good’ ‘effective’ c’ompetent’ teacher, what it
means to be an ‘educated’ person
•
Need to attend to the ‘logic of the discourse’ the rules implicit in the use of
particular words and those to which they are logically related
•
For Dewey “education concerned the development of the distinctively human
capacities of ‘knowing’ ‘understanding, ‘judging’; ‘behaving intelligently’
“(Pring 2000, p 12)
•
What that makes your study distinctive in relation to the field of education?
KEY FEATURES OF EDUCATIONAL RESEARCH
•
The attempt to make sense of the activities, policies and institutions which, through the
organisation of learning, help to transform the capacities of people to live a fuller, more
distinctively human life.
•
The distinctive focus of educational research must be upon the quality of learning and
thereby teaching
•
Much writing sets up a false dichotomy between different research traditions
•
Variety in approaches to educational research is desirable, depending on questions explored
and philosophical position
•
Is it the ‘real’ world that we observe – or one interpreted through my own personal &
subjective scheme of things?
•
What is the connection between language and the world language is used to describe? After
Pring (2000)
•
All links to notion of clarity in writing and argument &
demonstrating critical engagement with substantive, theoretical &
methodological literature
WHAT IS...?


A research design is “an integrated statement of and
justification for the technical decisions involved in
planning a research project” (Blaikie, “Designing
Social Research”, p. 15).
A research project is a temporary organisation that
is created with the purpose of carrying out systematic
and rigorous enquiry to address a particular problem
arising from a gap in knowledge (a theoretical puzzle,
a pragmatic need etc).
FEATURES OF QUALITY IN (EDUCATION)
RESEARCH
Rigour of research process
 Trustworthiness
 Reliability/ validity
 Usefulness – implications for research
methodology, for policy &/practice in education
 Originality
 Contribution to theory?

How can you demonstrate rigour in
these areas in your study?
WHAT IS PHILOSOPHY
RESEARCH?
OF EDUCATIONAL
A “second order activity” which explores



the beliefs about the nature of (social) reality or of a
phenomenon (including self and other – “what exists,
what it looks like, what units make it up and how
these units interact with each other”) - ontology
the beliefs about the nature of educational research
knowledge (and its relationships to other kinds of
knowledge) - epistemology
the beliefs about principles and values (including the
right, the good and the virtuous) in the practice of
educational research - axiology
(see D. Bridges, 2003, p. 15; N.Blaikie, 2000, p. 8)
WHAT IS/ARE YOUR...
...Ontological position?
...beliefs about epistemology?
•Positivist ?
•Constructivism
•Post-positivist?
•Pragmatic?
•Critical Theory
HOW DOES THIS AFFECT YOUR CHOICE OF:
• RESEARCH
• RESEARCH
AIMS & QUESTIONS?
DESIGN & METHODOLOGY?
Quantitative?
Qualitative?
Mixed Methods?
QUANTITATIVE VERSUS QUALITATIVE




Some researchers have argued that it may be
appropriate to think of Qualitative & Quantitative as
being on a continuum Gray and Densten (1998),
Tashakkori & Teddlie 2003
‘Qualitative and quantitative choices viewed as polar
opposites may be viewed as a ‘false dualism’ (Frazer
1995)
Can you clarify & justify your own view and
approach in your study?
How has your view evolved over the course of your
PhD research?
Pragmatism as the Foundation for MM Research
Pragmatism supports the use of both QUAL & QUAN
methods in the same study & rejects the either/or
incompatibility thesis
It considers the research questions to be more
important than either the method or paradigm that
underlies the method – the dictatorship of the RQ
Pragmatism
avoids the use of metaphysical concepts eg ‘truth’
‘reality’
Pragmatism presents a very practical & applied
philosophy
After Tashakkori & Teddlie 2003 p 20-21
RESEARCH QUESTIONS

The ‘big’ research question: one over-arching
question

The sub-questions which help to guide your enquiry
Characteristics of Good Research Questions
Clarity
 Empirical focus
 Accessible evidence
 Manageable
 Awareness of
assumptions
 Awareness of implicit
values

Awareness of political
implications
 Related to previous
research
 Significant
 Ethical
 Practical use (relevant)
 ‘fun’ (interesting to you)

source: Ingrid Lunt.
CLARITY
The question(s) in your study should be
answerable i.e can be illuminated or addressed
by your methodology (you are looking to find the
answer to a genuine question)
 The question should be intelligible to the reader
who may not be an ‘expert’ in your topic
(understandable)
 The questions should offer the prospect of
making an ‘original contribution to knowledge’ in
some way (methodologically theoretically
empirically etc)
 Are the terms clearly defined?
 Are the questions precise?

source: Ingrid Lunt.
EMPIRICAL FOCUS



Require that you generate data to answer question
Lead you to determine methods of enquiry and data
collection
NB it is usually most appropriate for methods to
follow questions; different types of questions will lead
to different approaches to research and methods of
data collection, but this is not always the case
source: Ingrid Lunt.


Reflect on your own Research aims/RQs:
How have they evolved over the course of your study
How far have they driven your choice of design &
methodology and the specific methods you are using?
SIGNIFICANT
Is there a clear rationale for the question?
 So what?
 Does this question matter?
 Why is it of interest and to whom?

source: Ingrid Lunt.
POSSIBLE AIMS & OBJECTIVES
Description: what does it look like (what, when,
where, who)?
 Explanation: why did it happen?
 Prediction: what is to be expected?
 Understanding: how is it grasped in human
experience?
 Interpretation: what does it mean?
 Prescription: how ought it be?
 Change and emancipation: how can it be
transformed for the better?
 Critique and disruption: what are the limitations
and hidden assumptions? How can these assumptions
be challenged/ interrupted?


Etc. (e.g., exploration, demonstration, classification)

SOME INFLUENCES ON SOCIAL RESEARCH
Values
•
These can affect choice of
research topic, formulation of
research questions, choice of
methods, choice of research
design and instruments,
ethics, sample & process of
data collection, interpretation
of data and findings,
conclusions, reporting and
dissemination
•
Need be self-reflective, and to
exhibit reflexivity about the
part played by the
researcher’s own values and
their potential influence on
research process and
outcomes
Practical Considerations
•
Existing knowledge base on
topic, is this a new topic of
interest? (generation or
testing of theory more
appropriate?), resources
available,
availability/interest of
participants
•
All social research is a
coming together of the ideal
and the feasible
As by Alis Oancea.
ROLE OF VALUES & OF RESEARCHER
•
The value determined nature of enquiry in anti- positivist
research such as Critical theory and Constructivism,
Advocacy and activism encouraged, researcher
transformative intellectual or passionate participant
•
What can be known is mediated by interaction between
investigator and subject of investigation
•
For constructivists there are multiple realities, that depend
on the individuals or groups holding constructions,
constructions may change/be altered and thus so can
‘realities’
•
Researcher and subject are interactively linked and
findings are created through hermeneutical and dialectical
techniques and are relative
•
Aims to critique & transform (critical theory) or to
understand & reconstruct, subject to continuous revisions.
HOW VALUES MAY INFLUENCE SOCIAL
RESEARCH
•
•
•
•
•

•
Choice of research area
Formulation of research questions
Choice of method
Formulation of research design & data collection
techniques
Implementation of data collection
Interpretation of data
Conclusions drawn
BODIES OF KNOWLEDGE
•
Theories, propositions and explanations
accumulated through enquiry, criticism,
argument and counter argument. What has
survived testing and criticism…public property.
Their credentials depend upon their being open
to public challenge and refutation.
•
Any body of knowledge can only be provisional
and is open to further challenge through
criticism.. The link between knowledge &
certainty is broken.
•
Disciplined, critical and reflective thinking is the
mark of educational research, at odds with
unquestioning ‘common sense’ beliefs.
POINTS TO ESTABLISH IN EXAMINING DIFFERENT
RESEARCH APPROACHES & IN CRITICAL READING OF
RESEARCH
•
Research assumptions - are they explicit?
•
Aims – explanation or understanding
•
The subjective-objective dimension
•
Role and definitions of theory
•
Doing research/reading research
•
Theoretical and empirical domains
•
Values and interpretation
•
•
Use of findings/ audience


All the same problems as
with Quant and Qual!
But also:
Design choice
Data synthesis
Can your data inform one
another?
Two separate studies?
Quant and Qual findings dont
match?
Skill and confidence in both
research approaches?
Should be more than the sum
of its parts.
Strategies




Careful design of each (Qual
and Quant) component.
Think about how your data
might be used to inform one
another.
Explore what the combined
set of findings indicate.
If not confident with a
particular method, hit the
books, ask for help!

Identify ontological position, epistemological &
methodological assumptions
Is researcher’s value position explicit?
Identify location, date, sample, methods used
Examine use of theory, deductive? Inductive?
Are analysis methods clearly explained ?
Are conclusions appropriately supported by evidence ?
What are the implications for policy/practice?




No study can be ‘perfect’
Research rigour is about clarity of research process
throughout
Justifying your choices, design, interpretations, conclusions
Persuasion of arguments re original contribution
Awareness of strengths & limitations
How your research fits into existing body of knowledge
Implications for policy practice, future directions for research

Your viva involves an oral ‘defence’ a justification
of the rigour of your research to probe your
understanding and ‘ownership’ of your study

It is helpful to practice thinking, talking about and
presenting your study with special attention to
demonstrating rigour
