Transcript
  • 1. Chapter 2 Research Problems Mary Ersinghaus New Mexico State University

2. Highlights of Chapter 2

  • Research problem statements
  • Quantitative research problems
  • Qualitative research problems
  • ...and questions we still have

3. 3-2-1

  • List3concepts from this chapter that you think are the most important.
  • List2things from this chapter that will be most useful to you.
  • List1question you still have about the ideas in this chapter.

4. Sources of Research Problems

  • Personal interests
  • Current issues and problems as identified by professionals
  • Current books or journals
  • Apply theory
  • Replication
  • Clarification

5. Research Problem Statement

  • Discussion question:
  • How is it possible for a research problem to be too specific? (McMillan, 2008, p. 52)
  • How would you balance between being too specific or too general in writing the research statement?

  • Start at 1:55

6. Quantitative Research Problems

  • Three specific elements are identified:
  • Type of research - description, comparison, relationship or difference, cause and effect
  • Variables - relationships between or among variables
  • Subjects -population involved in the study

7. Qualitative Research Problems

  • Focus on the study of a central phenomena (i.e., issues or processes)
  • Examples of issues
    • Drop out rates in high schools
    • Lack of recess and increased disruptive classroom behavior
  • Examples of processes
    • How teachers communicate with students' parents
    • How students perceive a teacher's care or lack of care

8. Research Problems

  • Quantitative problems
  • WHY?
  • Researchable
  • Important/relevant
  • Indicate type of research
  • Specifics
  • Clear

Qualitative problems HOW?WHAT?General Evolving, flexible No expected results Central phenomena 9. Quantitative Research Problem Types of Variables

  • Independent and dependent variables
    • Influences or predicts
    • Affected or predicted
  • Extraneous and confounding variables
    • Sources of error affecting result
    • Varying degrees of influence
  • Continuous and categorical variables
    • Takes on any value in continuum
    • Assign subject or object to a category

10. Identifying Types of Variables

  • The effect of two instructional approaches on student achievement.
  • The use of SAT scores to predict freshman grade point averages.
  • Not controlling for the key-boarding skills of students in a study of computer-assisted instruction.
  • Not using counselors with similar levels of experience in a study comparing the effectiveness of two counseling approaches.
  • Test scores range from a low of 0 to a high of 100.
  • Attitude scales that range from very negative at 0 to very positive at 5.
  • Students ages
  • Gender: male and female
  • Socio-economic status: low, middle and high

11. Research Hypotheses

  • Discussion question:
  • In what types of situations is it appropriate to use research hypotheses? Is it more related to quantitative or qualitative research? Why?

12. Research Hypotheses

  • Types of Hypotheses
  • Inductive
    • formed from observations of behavior
    • tentative explanation of how behaviors are related to variables
  • Deductive
    • derived from theory
    • testing contributes to better understanding of theory or application.

13. Research Hypotheses

  • More questions...
  • What purpose do hypotheses serve?
  • Criteria for evaluating research hypotheses?
  • Will all quantitative research problems have hypotheses?

14. Qualitative Research Question

  • Central Question:
  • What is the ______________________,
  • for ___________, at _______________?
