4. Sources of Research Problems
- Current issues and problems as identified by professionals
- Current books or journals
5. Research Problem Statement
- 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?

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)
-
- Drop out rates in high schools
-
- Lack of recess and increased disruptive classroom behavior
-
- How teachers communicate with students' parents
-
- How students perceive a teacher's care or lack of care
8. Research Problems
- Indicate type of research
Qualitative problems HOW?WHAT?General Evolving, flexible No
expected results Central phenomena 9. Quantitative Research Problem
Types of Variables
- Independent and dependent variables
- 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.
- Socio-economic status: low, middle and high
11. Research Hypotheses
- 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
-
- formed from observations of behavior
-
- tentative explanation of how behaviors are related to
variables
-
- testing contributes to better understanding of theory or
application.
13. Research Hypotheses
- What purpose do hypotheses serve?
- Criteria for evaluating research hypotheses?
- Will all quantitative research problems have hypotheses?
14. Qualitative Research Question
- What is the ______________________,
- for ___________, at _______________?
