This presentation was a basic introduction
to medical education research that will be
expanded upon in later sessions. We covered
five major areas: (1) research paradigms and
the overall research process; (2) how to
write a research question; (3) how to define
variables such as the independent and
dependent variables; (4) the basics of
research design; and (5) when to define your
study as research versus evaluation.
First, the difference between a deductive
versus inductive approach to research was
discussed and why these terms would be
useful for the discussion rather than
quantitative versus qualitative research.
The rest of the session focused primarily on
a deductive approach to research. After this
the overall process for research was
described followed by a discussion of how to
write a feasible, interesting, novel,
ethical, and relevant (FINER) research
question. This included how important it is
to do a thorough literature review prior to
developing your question and designing your
study. The importance of conducting a study
that is personally rewarding while also
being relevant to others was emphasized.
Next the definitions of independent,
dependent, and control variables were given.
Then an example research question was
provided where each major element of the
study (variables, research design, and
sample) was defined for the example
question. Next, various research designs
were briefly described, especially
experimental versus non-experimental designs
and when each would be appropriate. The two
requirements for an experimental design –
randomization to group and a control group
– were emphasized. In relation to a
discussion of research design, the concepts
of internal and external validity were given
with examples. These concepts were used to
demonstrate how one interprets data with
respect to the question and design and
potential limitations to the study.
Lastly, there was a discussion about the
difference between research and evaluation
studies. It was stressed that if one plans
on publishing one’s results then the study
is "research" and requires prior
Internal Review Board (IRB) approval. A take
home message was that study subjects, such
as students, cannot be required to be
subjects or to complete any research
instruments – research is voluntary. This
was contrasted to regular educational
evaluation done for courses or programs in
which you normally would require students to
complete examinations or evaluations as part
of student assessment or continuous quality
improvement. It was pointed out that if
later one decides to do research on already
collected data that is normally collected as
part of an educational experience (e.g.,
course) to do this one also needs to obtain
IRB approval prior to conducting the study,
but that one could treat the data as
"archived data." It was strongly
suggested that each researcher or evaluator
check with their own IRB office to discuss
their study prior to conducting it.
The formal presentation ended by
reviewing the research process from
literature review and writing and rewriting
the research question to data analysis with
the importance of starting with a good
measurable research question in order to
maximize the possibility of success.
