RES 866 Module 1 DQ 1
Scholarly research must be “aligned.” What does it
mean that research is aligned? Use the GCU Library to locate an empirical study
on the topic you are interested in researching. Give the APA-formatted citation
for the article along with the Permalink. Is the study you selected aligned? Why
or why not?
RES 866 Module 1 DQ 2
From the bibliography for your prospectus, select five
research studies that are most directly related to your own topic. Identify the
research design for each of those studies. State which of the GCU Core Research
Designs is used in each study. If the study uses a design not included in the
GCU Core Research Designs, note that as well. To what extent do the research
studies you identified influence the selection of the research design of your
intended dissertation study? Why?
RES 866 Module 2 DQ 1
It is not unusual for researchers to use a convenience
sample for their study. For example, if you would like to see if there is a
correlation between the time parents spend working with their children on home
work and the children’s school grades, you may consider recruiting your friends
and relatives to participate in your study because it will be easier to obtain
their permission for data collection. What might be some of the limitations of
this sampling approach?
RES 866 Module 2 DQ 2
What is the difference between a population and a
sample? How large do you think your population and sample will need to be for
your dissertation research? Explain your reasoning. What factors other than
size will you consider in relation to sampling? Why? What types of descriptive
statistics will you consider for summarizing the sample? Why?
RES 866 Module 3 DQ 1
From the bibliography of your proposed dissertation
study, select a peer-reviewed journal article that was done with a quantitative
methodology. Cite the article and summarize the study in one paragraph. Then
categorize it according to each of the following dimensions:
- Experimental,
quasi-experimental, or non-experimental
- Descriptive,
predictive, or explanatory
- Retrospective,
cross-sectional, or longitudinal
Why did you categorize the article as you did? Do
articles in your field of interest commonly fall into this category? Why or why
not?
RES 866 Module 3 DQ 2
What are the primary factors that make it more
challenging to conduct experimental studies in the field of education or
leadership? Why are these significant? How do these factors affect your own
research design for the dissertation study?
RES 866 Module 4 DQ 1
Suppose that you have collected data throughout a
semester from a large elementary school regarding the number of days per week
each math teacher spends in a collaborative teaching community. The average
ranges from 0 to 7 days per week. You have also obtained the pre-test and
post-test scores in math administered in those same classrooms in the beginning
and end of the semester, and you have calculated a score that shows learning
during the semester by subtracting the pre-test score from the post-test score
for each student.
You are interested in examining any potential differences
in student learning (i.e., post-test minus pre-test) that may be due to the
number of days of teacher participation in a collaborative community. What are
the independent and dependent variables? How can you best handle the data so
that you can perform group comparisons to examine the potential effect of the
IV on the DV? Why is this technique the best for handling the data?
RES 866 Module 4 DQ 2
Suppose that you have collected data throughout a
semester from a large elementary school regarding the number of days per week
each math teacher spends in a collaborative teaching community. The average
ranges from 0 to 7 days per week. You have also obtained the pre-test and
post-test scores in math administered in those same classrooms in the beginning
and end of the semester, and you have calculated a score that shows learning
during the semester by subtracting the pre-test score from the post-test score
for each student.
You are interested in examining any potential
differences in student learning (i.e., post-test minus pre-test) that may be
due to the number of days of teacher participation in a collaborative
community. Is group comparison the best approach to analyze the available data?
Why or why not?
RES 866 Module 5 DQ 1
Assume that you are interested in the relationship
between Graduate Record Examinations (GRE) scores (the total of all subtests)
and graduate school grade point averages (GPAs) at the end of their graduate
programs. Conveniently, you have access to the GRE scores and GPAs of a large number
of graduate students who have graduated from the electrical engineering
master’s program in an Ivy League university between 2000 and 2013. The Pearson
correlation coefficient did not reach significance. What can you conclude from
the data analysis? Can the result be generalized to all graduate students in
electrical engineering master’s programs across the United States? Why or why
not?
RES 866 Module 5 DQ 2
A researcher asks the question “Is there a
relationship between GRE total scores and GPAs in the master’s programs in
electrical engineering?” The researcher’s null hypothesis states, “There is no
correlation between GRE total score and GPA from an electrical engineering
master’s program.” The researcher’s alternative hypothesis states, “There is a
positive correlation between GRE total scores and GPA from an electrical
engineering master’s program.”
Are these valid hypotheses for the research question?
Why or why not? What other observations can you make regarding the hypotheses
and research question?
RES 866 Module 6 DQ 1
Suppose you are interested in how children with severe
autism experienced the receipt of special education assistance in public
schools. This population is characterized by underdevelopment of social
cognition, social skills, and language skills. What is the best method for
collecting data to answer your research question? Why is this method best? How
would you describe the research design?
RES 866 Module 6 DQ 2
Suppose you are interested in how children with severe
autism experienced the receipt of special education assistance in public
schools. This population is characterized by underdevelopment of social
cognition, social skills, and language skills. How many children should be
included in the study? Why? What are the factors considered in making this
determination?
RES 866 Module 7 DQ 1
Suppose you are interested in the behaviors of
physicians that have high ratings of patient satisfaction. The research goal is
to identify the behaviors in the natural clinical settings of these successful
physicians so that these behaviors can be built into the curricula of medical
preparation programs. The main data were collected by the video recording of
five randomly selected physician-patient encounters from 10 physicians who have
been rated highly by patients in a reliable satisfaction survey.
In analyzing the recordings, what would you define as
the unit for analysis? Why? How many data units (in rough estimates) are you
likely to get based on this decision? Does the estimated number of data units
seem adequate? Why or why not?
RES 866 Module 7 DQ 2
Suppose you are interested in the behaviors of
physicians that have high ratings of patient satisfaction. The research goal is
to identify the behaviors in the natural clinical settings of these successful
physicians so that these behaviors can be built into the curricula of medical
preparation programs. The main data were collected by the video recording of
five randomly selected physician-patient encounters from 10 physicians who have
been rated highly by patients in a reliable satisfaction survey.
Assume that you reviewed the literature on physician
communication skills as a major component of patient satisfaction. Based on
this idea, what might be some of the initial codes that you could use to label
the data units? How would you justify this set of codes in your research
report?
RES 866 Module 8 DQ 1
Please share the tentative research design from your
prospectus and provide a brief rationale for it. Also include the research
question(s) and the associated hypotheses (for quantitative studies only) in
their current state and describe how they align with your proposed research
design. What questions or concerns do you have surrounding your work at this
point?
RES 866 Module 8 DQ 2
Reflect on the information presented in this course.
How will the information on finding a content expert influence your research
plans? When did the course information give you new insight on your proposed
research methodology and design for your dissertation research study?
Will this new insight change anything in your prospectus? If so, what steps
will you take to update your prospectus? Explain.
