More Association and Conferences

•  To improve the experience, knowledge and competence of students and clinicians

•  To improve the care of patients and the health care outcomes generally

•  To deepen the field of health professions education research

Creating Increased Expectations

Health professions education research is undertaken:

•  In naturalistic / opportunistic settings

•  Without a theoretical base

•  With little funding

•  By isolated researchers

•  Published in a dispersed fashion, difficult to find

Why so much poor quality research?

Bordage  2000  

•  The conceptualization and research methods used are limited and narrow

•  Researchers are often isolated, in units with missions for teaching and administration rather than research

•  There is little funding for medical education research

•  Researchers unable to connect their work to a larger “conversation” in an academic discipline

Explanatory Factors

Albert  2005  

1.  Expand research questions and move from local studies to multi-institution and international studies

2.  Replicate existing research in varied settings

3.  Undertaken better controlled studies and support good qualitative research

4.  Created stables sources of funding for medical education research

5.  Formally train researchers

Solutions: According to Bordage

1.  Intensify collaboration between PhD researchers and clinicians interested in education research

2.  Support the diversification of disciplines which play a role in health professions education research

Solutions: According to Albert

•  108 medical faculty with an interest in medical education: survey and focus groups

•  40% had fellowship or masters training

•  Though most involved in a project, few had funding or published their work

•  No significant differences between those with and without additional education training

A masters or fellowship is not enough!

Zibrowski  2008  

Factors for success •  Education research support •  Enhancing colleague interaction •  Ongoing development activities

Barriers •  Protected time •  Access to a context and support staff that

sustains research •  Knowledge of research methodology (Does the

masters/fellowship actually teach research skills?)

Solutions according to Zibrowski

Goals of Education Research

Aims at building on existing knowledge and understanding of learning and education by

–  Studying phenomena, interactions, interventions

–  Formulating models, theories, and predictions

–  Studying what works, why, how and for whom

Related approaches

•  Evaluation, assessment, audit

•  Study of local, concrete problems and phenomena

•  Limitations: –  Do not contribute to advancement of

knowledge or theory building

–  Not part of a larger ”conversation”

Study of local, concrete problems

Evaluation ”What is the effect of this course in my

school regarding satisfaction, usefulness, learning, behaviour?”

Assessment ”What is the learning outcome of this

instruction or course assessed by MCQ or OSCE?”

Audit •  ”How well is our programme working in

our department regarding ...?”

Research

•  Starts with an idea, problem or case •  Relates the idea to conceptual framework •  Develops specific research questions •  Employs research approach, design, and

instruments •  Collects and analyse data •  Interprets results •  Discusses validity and generalisability (or

transferability) of results and practice implications

Two poles of medical education research

Theory driven research Deepen the knowledge and understanding of learning, teaching, training, education

Applied research Provide evidence of effect, justify initiatives, concepts, technology, expenditure

Stokes Quadrant Model of Research Not bird watching…

A single study at Kirkpatrick level 1 (Satisfaction) –  We created a course about #fv*7%d –  5 people took it –  3 of them filled out the evaluation form –  They all thought it was great

Sweeping generalization

–  We have shown it is feasible and acceptable to implement a course in #fv*7%d

–  Medical schools around the world should created courses in #fv*7%d

Knowledge Building Research

Process Did the simulation learning program operate well / as intended?

What organizational factors enable the successful development and implementation of simulation learning?

Outcome Were the learning objectives met? Did students learn?

How does simulation-enhanced education impact learners’ self-efficacy and perceived readiness for practice?

From Practical Evaluation to Knowledge Building Research

Asking a Good Research Question

Don’t start with a tool or data

•  “I’d like to do a survey” •  “I want to do a study on OSCEs” •  “I want to do something qualitative” •  “We have a lot of teacher evaluation

data - I’d like to do some research on it”

•  “My chair wants me to do some research on the clerkship”

Education Slide: C. Ringsted 2010

Define your problem

•  Think of an idea, problem, issue in education that has been on your mind

•  Write it down

•  Are you passionate about this problem or issue?

•  Explain the problem, and why it

interests you, to a neighbour

Page 6: HODGES Research workshop - short version 2015...Justifying Implementing s Modelling Predicting s Conceptual theoretical framework RCTs & Quasi- experimental studies Challenges with

2015-01-26

Perform a systematic review of literature

Conceptual frameworks

•  Relate your idea, problem, phenomenon to theories of learning and education (or sociology, anthropology, psychology, etc)

•  Identify models that explain underlying mechanisms of a phenomenon or why and how an intervention might work

•  Create a relevant framework for your study –  Appropriate design and valid methods

Find a conceptual framework

•  ”Conceptual frameworks represent ways of thinking about a problem or a study”

•  ”Different frameworks will emphasise different variables and outcomes, and their inter-relatedness”

•  ”Scholars are responsible for making explicit the assumptions and principles contained in the conceptual framework they use in their R&D projects”

Bordage 2009

Learn more about the problem

•  What, if any, investigation of this problem have you done already? –  Reading about it –  Talking with an expert –  Attend a lecture or workshop

•  Has anyone researched this problem before?

•  If you are to pursue a study about this problem, what will you need to know more about?

Generate an answerable question

Change your problem into a question

The nurses don’t allow the medical students to participate in deliveries

Our international graduates

have problems talking to patients

Students are resistant to

feedback about their OSCEs

Why do nurses not involve clinical clerks in the labour and delivery room?

In what ways do international

medical graduates have trouble with patient communication?

How do students perceive

feedback they receive from their OSCEs?

Ensure your question can be studied

•  Too vague: What is the meaning of life?

•  Too ambitious What is the best curriculum to train a professional

physician for the 21st century?

•  The PhD thesis How do methods of assessment of competence

used in countries around the world reflect their history and culture?

•  Reword, refocus, redefine your question as needed

Psychometric

Descriptive studies

•  Description –  Phenomenon, novel intervention, assessment

method, administrative procedure, organisation, population of individuals

•  Prevalence –  High in young research disciplines – Medical

Education and Emergency Medicine

•  Characteristics –  Reports with or without outcome data –  Make no comparisons

Conceptual theoretical framework

What is qualitative research?

The goal of qualitative research is: –  the development of concepts which help us

to understand social phenomena –  in natural (rather than experimental) settings –  giving emphasis to the meanings,

experiences and views of all participants Pope and Mays BMJ, 1995

Qualitative methods use language-based

rather than numerically-based data

When to use qualitative research?

1.  Preliminary to quantitative research

2.  Supplemental (triangulation) to quantitative data

3.  To explore complex phenomena not amenable to quantitative research

Qualitative and quantitative are not opposites

•  Often artificially seen as opposing poles •  Different, but complementary ways of viewing

similar phenomena Eg. Diabetes and insulin compliance •  Quantitative study: What is the relationship

between non-compliance (as measured by hemoglobin A1C) and disease progression?

•  Qualitative study: Why are patients not compliant? How do they view disease progression? Do they see a relationship with compliance?

Qualitative methodology and method

Methodology •  Historical

method •  Ethnography •  Phenomenology •  Discourse

Analysis •  Grounded

Theory

Method •  Interviews •  Focus Groups •  Case Studies •  Text Analysis •  Observation

• Naturalistic / Interpretive –  Study phenomena in

natural settings –  Meanings participants

bring to phenomena • Specific to context studied • Individuals’ values involved: participants’ & researchers’

RCTs & Quasi- experimental

Challenges with RCTs in education

•  Samples –  Size and representativeness

•  Interventions –  Definition of intervention

and control circumstance –  Standardisation of intervention

•  Measurement –  Identification of valid outcome measure –  Appropriate measurement points

Page 9: HODGES Research workshop - short version 2015...Justifying Implementing s Modelling Predicting s Conceptual theoretical framework RCTs & Quasi- experimental studies Challenges with

Measurement points

•  Before measurement –  Testing might have an effect on learning in

itself –  The test might be remembered

•  After measurement –  Measurement immediate after intervention –  Measurement after a pause, retention test –  Measurement of transfer

•  Another, but similar task •  A more complex task •  Another context

Experimental design

•  Learning is a sustainable change in capacity to perform –  Measure retention and/or transfer

•  Be aware of the testing-effect Randomized design R Ob X1 Oa Or/Ot 4-group Solomon R Ob X2 Oa Or/Ot before-after R X1 Oa Or/Ot retention/transfer R X2 Oa Or/Ot design

Other concerns about RCTs

•  Ethics, blinding, and feasibility – Matched groups, ’waitlist’ controls

•  Validity – RCTs are the best design to find

out if an intervention works – The worst design to find out who

it works for and the long-term effects the intervention

Measurement

•  Test-enhanced learning – Testing has an intrinsic effect on

memory

•  Effect of stress on learning and performance

Feedback and learning

•  Training program: Vascular anastomosis, plastic model –  Distributed over 1 week –  Massed in 1 day

•  Measurement points –  Pre-test –  Post-test –  Retention 1 month after –  Transfer, live animal

Case-control studies

•  Study the cause or consequence of differences that already exist between or among groups

•  Useful for studies where –  Outcome is categorical

•  Yes/no or present/absent

–  Prevalence of outcome is low •  Rarely observed phenomenon

–  Time delay until outcome is long •  Years

Associational studies

•  Aims at –  Describing phenomena by

identifying the degree of an existing relationship among variables

–  Clarify understanding and seek to predict a certain outcome

•  However .... –  Conceptual, theoretical

framework is crucial to interpretation of cause and effect

that…” •  “I believe that…”

Unearth your assumptions

What is the answer(s) to your question?

Write down what you think it might be (even if you are not sure - even if you just ‘suspect’ them to be true)

It’s OK to do this - really!
