    Question: (p. 129) How do you identify intervening variables in your own research study?
    Is this done before, during, and after the research process?

    Quote: (p. 123) "Good research links the purpose statement and questions to major results."

    Fact: (p. 124) There is a difference between characteristics of individuals (personal aspects such as grade level, age, income level) and attributes (how people feel, behave, think).

    Question: My question concerns control variables (pg. 128). Why do you need to "neutralize" control variables and control them through statistical procedures? How can they be statistically controlled and adjusted, and why would you want or need to?

    Quote: pg 123 (Regarding purpose statements, research questions, hypotheses, and objectives) "Without clear signposts, the readers will be lost throughout your study."

    Fact: Confounding variables interest me because of their uncontrolled and extraneous nature. It is refreshing to know that all things human cannot be measured, and that even statistics and research can be "messy". (borrowing Dr. Smith's term)

    Question: I read where in quantitative research a theory is found in the research and the relationships are tested. Do theories have a place in qualitative research? (Maybe I missed it!)


    Quote: Page 123 “Without clear signposts, the readers will be lost throughout your study.”


    Interesting fact: Hypotheses aren’t just educated guesses. A researcher bases them on past researches and literature.

    Question: Is the qualitative research design process supposed to be emerging as the research is done due to the fact that it is more opinion and observation of participant based rather than statistical gathering?

    Quote: Page 125 "Certainly all children think what varies is how they think differently, such as when they engage in the activity of writing."

    Interesting Fact: The independent variable "probably caused" the dependent variable. Probable causation. (I never thought of it that way.)

    Corey,
    I like your quote about having clear "sign posts" within your research. I believe having those are extremely helpful for those of us like me that when reading research need to be kept on track and given a clear and straight road map. Other wise if they are not there the research can seem a bit overwhelming.

    Corey...

    I am wondering if I should reevaluate a bit how I explain to my student's what a hypotheses is. For many years I have referred to it is an educated guess. Do you think I need to go back and clear this up in order to deter any misconceptions? Because they hypotheses really drives my student's scientific investigations and inquiry process.

    Mrs. Dalrymple - I am thinking based upon what I read the intervening variable in your research study would be identified during your research. Unless you already are away of how each of your variables are going to interact. I believe that to see how they intervene the study will have already begun.

    Dr. Hendrix....any thoughts? I am curious about this now as well.

    Question: Why is the use of research objectives limited in educational research today?

    Quote: (123) "Good research links the purpose statement and questions to major results."

    Fact: Questions and purposes may change in qualitative research because the researcher allows the participants to set the direction.

    Interesting Fact: When discussing hypotheses, researchers base specific predictions on results from past research and literature. Page 122


    Question: What does it take to have an accurate purpose statement?


    Quote: A theory can be seen as a bridge explaining the relationship between the independent and dependent variables.

    Ann,

    Yes, you find themes from your qualitative research, and you discover more. It is more exploratory.

    Good question here,
    Dr. Hendrix

    Question: Is there a good way to decide whether or not one has identified all possible intervening variables?

    Quote: "Not all quantitative studies employ a theory to test, but doing so represents the most rigorous form of quantitative research." page 131

    Interesting Fact: You will use an alternative hypothesis if you think there will be a difference based on results from past research. page 137

    Interesting Fact: I find it so happy for me to see how close this chapter is related to fifth grade science! I feel like I am starting to understand it a bit more. "Researchers study independent variables to see what effect or influence they have on the outcome." pg 127

    Quote"In most research studies, investigators seek to learn more than responses to single variables. They may examine the relationship between two or more variables. pg 135

    Question: It seems as if you can subquestion yourself to death in qualitative questions. How do you know when to stop with the subquestions?

    Question:
    Do subquestions help validate the research study? If so, how?

    Quote:
    " In addition to central question, qualitative researchers pose subquestions. These subquestions refine the central question..." p138

    Interesting Fact:
    A family of variables in quantitative studies often test the relationship among variables using theories.
