The Purpose of Research: Exploratory, Descriptive, and Explanatory Studies
Research
•
A detailed study of a subject , especially in
order to discover new information or reach a
new understanding (Cambridge dictionary)
•
Research
is defined as the creation of new
knowledge and/or the use of existing
knowledge in a new and creative way so as to
generate new concepts, methodologies and
understandings.
•
Research is a process of systematic inquiry
that entails collection of data; documentation
of critical information; and analysis and
interpretation of that data/information, in
accordance with suitable methodologies set
by specific professional fields and academic
disciplines.
What is the purpose of research?
There are three main purposes:
•
Exploratory:
As the name suggests, researchers
conduct
exploratory studies
to explore a group of
questions. The answers and analytics may not
offer a conclusion to the perceived problem.
•
Exploratory research is defined as a research used
to investigate a problem which is not clearly
defined. It is conducted to have a better
understanding of the existing problem
•
Surveys/polls
:
•
For example: A survey is sent to a given set of audience
to understand their opinions about the size of mobile
phones when they purchase one.
•
Focus groups:
Focus group
is yet another widely used
method in exploratory research. In such a method a
group of people is chosen and are allowed to express
their insights on the topic that is being studied.
Although, it is important to make sure that while
choosing the individuals in a focus group they should
have a common background and have comparable
experiences.
Descriptive
•
It focuses on expanding knowledge on current
issues through a process of data collection.
Descriptive studies describe the behavior of a
sample population.
•
The three primary purposes of descriptive
studies are describing, explaining, and
validating the findings.
Explanatory
•
Causal or
explanatory research
is conducted
to understand the impact of specific changes
in existing standard procedures. Running
experiments is the most popular form.
Educational research can take a wide variety of forms and
serve many different purposes. Sometimes it is located
within social science disciplines, especially psychology
and sociology.
Other work is of a more policy-oriented nature, and some
is quite closely linked to educational practice.
There is also diversity at the level of methods used. These
include: laboratory and classroom experiments;
Large-scale surveys of the behaviour, attitudes, aptitudes,
etc., of teachers, children, heads, and others;
and
Small-scale investigations of particular institutions or
locale.
•
A common way of conceptualizing this
diversity in method and data is the distinction
between quantitative and qualitative
approaches, between research which relies
primarily on numerical data and that which
uses mainly verbal data.
DEVELOPMENT OF
EDUCATIONAL RESEARCH
•
Educational research began in the late
nineteenth and early twentieth centuries.
Before that much had been written about
education, but this had been primarily
concerned with how children should be
educated.
•
This initial connection was with psychology.
•
Then it led to a commitment on the part of
educational researchers not just to a scientific
approach to their work but also to a particular
interpretation of the methodological
requirements of science.
•
This placed great emphasis on the need for
quantitative measurement of the characteristics
of learners and teachers, and of their behaviour.
Experimental method was regarded as the ideal
model of a scientific approach, even though by
no means all early educational research was
experimental in character.
•
A particularly important aspect of this early
history of educational research was the
construction of mental tests of various kinds -
of intelligence, academic achievement,
personality, and attitude — which were
applied to pupils.
•
Alongside these were developed various
rating scales and observational schedules for
measuring aspects of teachers' behaviour.
•
Such tests and behavioural measurements
were believed to offer teachers, educational
administrators and others valuable
information of an objective kind which would
facilitate both effective educational planning
and the monitoring of educational processes
to assess their success.
Some Tips for conducting good
research
•
Identify the main trends and issues,
opportunities, and problems you observe
•
Evaluate a list of the strengths, weaknesses,
opportunities, and threats that have been
identified in a SWOT analysis.
•
Look for gaps in the information, and consider
doing inquiry if necessary
•
Review ample studies their results and consider
efficient methods to analyze and intrepret the
results
Key Differences Between Exploratory
and Descriptive Research
•
The difference between exploratory and descriptive research can be drawn clearly on the
following grounds:
•
Research conducted for formulating a problem for more clear investigation is called
exploratory research. Research that explore and explains an individual, group or a situation, is
called descriptive research.
•
The exploratory research aims at the discovery of ideas and thoughts whereas the primary
purpose of descriptive research is to describe the characteristics and functions.
•
The overall design of the exploratory research should be flexible enough so that it provides
an opportunity to consider various aspects of the problem. On the contrary, in descriptive
research, the overall design should be rigid which protects against bias and also maximise
reliability.
•
The research process is unstructured in exploratory research. However, it is structured in the
case of descriptive research.
•
Non-probability sampling i.e. judgment or purposive sampling design is used in exploratory
research. As opposed to descriptive research where probability (random) sampling design is
used.
•
When it comes to statistical design, exploratory research has no pre-planned design for
analysis. Unlike, descriptive research that has the pre-planned design for analysis.
Research is a systematic inquiry process that involves data collection, critical information documentation, analysis, and interpretation. It serves three main purposes: exploratory research to explore questions, descriptive research to expand knowledge on current issues, and explanatory research to understand the impact of changes in procedures through experiments. Different methods such as surveys, focus groups, and data collection are used to achieve these purposes.
