Title
This
study is entitled Challenges and Prospects for Students with Intellectual
Disabilities in Nigeria.
Problem
statement
There
are many challenges that students with intellectual deficits face while
consuming their social and educational lives. Research has previously exposed
some of these challenges though not at a deep perspective. Different
methodologies have been applied to study these challenges and identify feasible
remedies. However, not many researchers who apply the qualitative designs
conduct comparable quantitative approaches to find out whether similar results
can be identified.
Purpose
The
purpose of this paper is to compare and contrast the qualitative and
quantitative research designs commonly applied in research and which can apply
in the studying of the challenges and prospects for students with intellectual
disabilities in Nigeria. The second objective is to select either the
qualitative or quantitative approach and discuss the best practices for the
selected design.
Research
questions
The
following research questions guide this research paper.
1.
What is the meaning and applications of
the qualitative and quantitative research designs?
2.
What are the similarities and differences
between the quantitative and qualitative research designs?
3.
What are the expectations of each of the
above research approaches for a typical study?
4.
Which of the designs (qualitative or
quantitative) best suits this study and what are the best practice suggestion
of the method selected?
The Qualitative Research Method
Qualitative
research method refers to a research method used to study non-quantifiable
characteristics such as human attributes like behavior and habits (Brew &
Lucas, 2009). In this design, the data or information to be gathered is not
numerical; the Respondent discusses or answers most of the questions based on
his or her point of view rather than give provable facts. As such, a
qualitative research design can be said to harbor the following
characteristics. Fist, an interview guide is a primary tool for data collection
of a qualitative study, though other methods can be incorporated such as
observation and the questionnaire method. If a questionnaire is used, it has to
contain only or mostly the open-ended questions (Kothari, 2005). That leads to
the second feature of the qualitative research strategy that it is focused on
non-factual information. Due to the inclusion of open-ended items, the
respondent has the liberty to give true or non-true information.
Thirdly, this type of research is short of
range and utilizes a smaller population compared to the quantitative research
types. That is due to the limitation of interviewing exercise that consumes a
lot of the researcher’s time. As posted by Kothari (2005), the qualitative
study requires researchers to spend a larger a lot of time to gain a full
understanding of the phenomena under investigation. Lastly but not least, most
items in this type of research addresses the why of a phenomenon under
consideration and as such mostly lead to a quantitative study post results.
A
qualitative research is sometimes considered stronger than the quantitative.
That is due to the following reasons. Firstly, it allows for the various levels
of variables to effectively and sufficiently affect the outcome (Christensen,
Johnson & Turner, 2010). Also, the study tool (interviews) allows the
researcher to investigate the subject in further depth with regards to a
particular issue as he/she has greater control during the conversation. It is
also simpler as it allows subjects to be studied or observed in their natural
environments. It is also flexible, and the researcher can at any time alter some
questions and direction of inquiry to be deeper insight into a phenomenon.
However, it is weaker than the quantitative as it allows flexibility of
respondents input, some of which can be false and skewed (Kothari, 2005).
Quantitative Research methods
Quantitative
research methodology refers to the process whereby the data is gathered
systematically, entered, analyzed and reported in numerically formatted
statistical values in the bid to explain what was observed in response to the
hypothesis (Brew & Lucas, 2009). Here, the researcher is mostly clearly
conscious of the specific information being sought before the initiation of the
study. As such, data collection will be expected to adhere to a specific and
practically rigid framework. Characteristically, the quantitative research
methodology utilizes large groups of respondents. That is due to the use of
surveys or questionnaire as the primary tool of questionnaires with minimal of
interviews (Balnaves & Caputi, 2001).
The
use of questionnaires makes the data collection face quicker and extensive as
it only requires the researcher to disseminate the questionnaire either through
hand delivery or email or parcel posting. It is thus less time consuming. This
type of research is accurate as it allows for variables with statistical
outliers to be frequently discarded. That is because numerical data reporting
may be more factual as the respondent might be forced to check his records
rather than answer a particular inquiry by mere thoughts (Christensen, Johnson &
Turner, 2010). The analysis phase is also quicker. Contrary to the qualitative
approach where data is to be first coded and then entered into statistical
analysis tools, the quantitative data is mostly entered directly and analyzed.
There is a disadvantage to the quantitative research as compared to the
qualitative. The questionnaires for this type of research often contain
closed-ended questions with only a few answer options. That discourages most of
the respondents who may leave some questions unanswered (Brew & Lucas,
2009).
Summary of Similarities and
differences
Similarities
There
are several aspects in which qualitative and quantitative research designs are
similar. First of all, both are methods of research which are limited by
variables. Firstly, qualitative and quantitative research methods may be used
to study the same phenomenon. Though the qualitative method might be used in
this case to scrutinize on the challenges of these students whereas the
quantitative would be used to measure the frequency or total of students facing
a particular challenge, both would supplement each other for extensive
investigation of the same hypothesis (Balnaves & Caputi, 2001).
Besides,
the qualitative research is affected by the researcher conducting the research.
For instance, the different researcher may choose to gather different
categories or pieces of information and different ways to interpret it.
Apparently, the choice of each will have a significant impact on the outcome of
research (Kothari, 2005).
There are also
considerations to make when applying any of the two methods. Firstly, a pilot
study should be conducted to validate the tools of data collection. (Christensen, Johnson & Turner, 2010).
Secondly, the sample size is an important feature to be considered in both.
Deciding an appropriate sample size is critical in both regards is critical for
the following reasons. First, a good sample size should be large enough to be a
feasible representative of the population. That limits the influence of
outliers or extreme observations in the analysis. Sample size determination is
also important for economic and ethical purposes (Christensen, Johnson &
Turner, 2010).
Differences
Firstly,
the qualitative research mainly focuses on gathering verbal data rather than
measurements. The gathered information is thereafter analyzed in an
interpretative manner, subjective, impressionistic or even diagnostic. The
second difference is on aim, the basic objective of a Qualitative Research is
to provide a comprehensive, detailed description of the research topic. On the
other hand, a quantitative Research focuses deeply into the counting of
features and finally constructing statistical models and figures to summarize
what was observed (Brew & Lucas, 2009). Thirdly, compared to qualitative
research, the quantitative research designs provide the researcher clearer
pictures of what to expect as results before engaging in the research phases
(Brew & Lucas, 2009). Fourthly, as seen earlier, the data collection tool
for the qualitative research designs is the interviews while the questionnaires
are basic to a quantitative inquiry.
The
type of data to be collected also differs. Most questions in a Qualitative
Research require responses in the form of words (interviews), images (such as
videos) or objects (such as artifacts). On the other hand, data in a
Quantitative Research will mostly appear in numerical figures in the form of
raw data tables and statistical analysis tables (Balnaves & Caputi, 2001).
Qualitative
or Quantitative
Having
seen the strengths, weaknesses and applications of the quantitative and
qualitative methods of research, I choose to use the qualitative methods for
this study. I chose this method because the topic of study ‘challenges and
prospects of students with intellectual disabilities in Nigeria’ does not
necessarily require much of numerical evidence. Best practices suggestions in
the qualitative study methodology include the following. First is a case study.
The purpose of this qualitative study approach will be to describe in depth the
experience of students with intellectual disabilities through direct
observation and interaction with each student respondent (Creswell, 2009).
The
second qualitative approach I will use is the ground theory. This approach is
used in uncovering the problems that exist in social scenes and how individuals
may handle them. Though its main purpose is to develop a theory, the findings
can be used to explain what challenges the students to face, and necessary
interventions concluded (Creswell, 2009).
