The
insight I have gained throughout this course has provided me the knowledge to
better understand the variables that are involved in qualitative and
quantitative research designs. In these types of research designs the variables
are the independent variable, the dependent variable, and the extraneous
variable.
An independent variable is a variable in
quantitative research that can be manipulated by the researcher to influence or
change another variable (Lepuschitz, 2011).
For instance, in my research simulation, poverty is the independent
variable because it influences children’s ability to achieve developmental
milestones. The groups will be established based upon socioeconomic
status. One group will experience having
early childhood resources, and the other group will not have access to early
childhood resources.
A
dependent variable is the variable in quantitative research that undergoes
changes as a result of the influence of other variables (Lepuschitz,
2011). For example my research
simulation, children’s ability to achieve developmental milestones would be the
dependent variable because children’s ability to achieve developmental
milestones are influenced by outside factors or variables.
By
recognizing this limitation, I have identified my extraneous variable. An extraneous variable is a variable in
quantitative research that is not the focus of the research, but can influence
change in another variable (Lepuschitz, 2011).
The availability of early childhood resources in children’s community would
be an extraneous variable because it also influences children’s ability to
achieve developmental milestones.
My
ideas about the nature of research have changed because I have better
understanding of what is needed to
ensure the validity of methodological triangulation. According to Mac Naughton, Rolfe, and
Siraj-Blatchford (2010), ‘’validity is the process of establishing the ‘truth’
of the research outcomes’’ (p. 370).
More specifically to qualitative research, validity is a statement that
judges the extent of the research’s ability to capture valuable information of
the field being studied as well as analyzes them with integrity (MacNoughton,
Rolfe, & Siraj-Blatchford, 2010).
Through the process of triangulation, qualitative researchers are able
to build a robust picture of events by analyzing data from various perspectives
as an attempt to reduce aspects of bias.
In methodological triangulation, researchers use multiple methods to
study a single issue (MacNoughton, Rolfe, & Siraj-Blatchford, 2010). In my opinion, through methodological
triangulation researchers are able to get a full view of what is being studied
due to having the ability to use multiple methods to better understand the
issue being studies. In the field of early childhood, I believe this method is
most beneficial because it allows us as early childhood professionals to better
understand the meaning behind children’s development and learning strategies
due to the uniqueness of children individual development. I believe methodological triangulation
contributes to the validity of a study because through this method sample
groups are able to show different ways they can attempt various tasks which
will provide researchers with information to better understand the issue being studied.
Concluding
this class, I feel I have learned many lessons about mixed methods. By understanding mixed methods designs I was
better able to undertreated my research simulation on poverty’s effects on
children’s ability achieve developmental milestones. I
believe that using mixed method approach with my research simulation on
poverty’s effects on children’s ability to achieve developmental milestones would
be beneficial due to fact that mixed methods approach ‘’allows inclusion of
issues and strategies surrounding methods of data collection, methods of
research, and related philosophical issues ’’ (Johnson, Onwuegbuzie, &
Turner, 2007, p. 125). Throughout my
research simulation I have found it very useful to use various types of
qualitative research designs to better understand my research question as well
as how to narrow down the focus of the study.
By using mixed methods I am able to better understand the individual
development of each child in the sample groups due to using various ways to
collect data through questionnaires, interviews, and observations. The main reason I perceive using mixed
methods in my research simulation is because ‘’mixed methods research involves
the use of more than one approach to or method of design, data collection or
data analysis within a single program of study, with integration of the
different approaches or methods occurring during the program of study, and not
just at its concluding point’’ (Johnson, Onwuegbuzie, & Turner, 2007, p.
123). In other words, my research
simulation would benefit greatly by using a combination of any different
approaches, methods, data, and analyses as a way to better understand
children’s development from both low and high socioeconomic statuses.
The
challenges I face throughout this courses is understanding the terminology used
in the course textbook. I was able to
meet this challenge by downloading a dictionary and synonym application on my
smart phone as an attempt to understand the meaning of words.
My
perception of early childhood professionals has been modified due to adding
researchers to the title of ‘’early childhood professional’’. Researchers provide early childhood educators
with valuable information about the development of children as well as provides
us with information based from children’s perspectives which has allowed the
field of early childhood to better accommodate the individual needs of children
and their families.
