1. Writing Qualitative Purpose Statements

1.1. Purpose statement in qualitative research: indicates the intent to explore or understand the central phenomenon with specific individuals at a certain research site

1.2. Sentence, at the end of the introduction

1.3. Sample Script

1.3.1. The purpose of this qualitative study will be to (explore/discover/understand/ describe) (the central phenomenon) for (participants) at (research site).

1.3.1.1. Example

1.3.1.1.1. The purpose of this qualitative study is to describe classroom learning using the Internet for five high school students participating in a sign language class.

2. Distinguishing Qualitative Research Questions from Data Collection Questions

2.1. Interview questions are based on issues subquestions.

2.2. Also, ask other questions, like and opening about the participants.

2.3. Might close with question about others to interview.

3. Research variables (a variable is defined as an attribute of an object of study)

3.1. Why we need them?

3.1.1. To write quantitative purpose statements, research questions, and hypotheses, you need to use variables.

3.1.1.1. To know what is a research's variables

3.1.1.2. To know what is a research's theory

3.1.1.3. To know what is a research elements that go into these statements and questions?

3.2. What they are?

3.2.1. A variable is a characteristic or attribute of an individual or an organization that

3.2.1.1. (a) researchers can measure or observe and

3.2.1.2. (b) varies among individuals or organizations studied

3.3. Their characteristic

3.3.1. Measured

3.3.1.1. Can be assessed on instrument (example: survey)

3.3.1.2. can be observed on instrument (example: survey)

3.3.1.3. can be recorded on instrument (example: survey)

3.3.2. Varies

3.3.2.1. Can assume different values

3.3.2.2. scores for different individuals

3.4. How to Specify Variables?

3.4.3.1.4. Stereotypes

3.5. Variables Types (Distinguish between Variables)

3.5.1. Mesured as Categories and as Continuous Scores

3.5.1.1. A categorical measure is a value of a variable assigned by the researcher into a small number of categories (e.g., gender).call this type of measure a discrete or nominal score

3.5.1.2. A continuous measure is the value of a variable assigned by the researcher to a point along a continuum of scores, from low to high (e.g., age).

3.5.2. Variables vs. Constructs

3.5.2.1. A variable is an attribute or characteristic stated in a specific or applied way(e.g., grade point average)

3.5.2.2. A construct is an attribute or characteristic expressed in an abstract, general way (e.g., student achievement)

3.5.3. The Family of Variables

3.5.3.1. Independent variables

3.5.3.1.1. Definition: An attribute or characteristic that influences or affects an outcome or dependent variable

3.5.3.1.2. Another Definition: What variables or factors influence the outcomes?

3.5.3.1.3. Different Sort of Independent Variables

3.5.3.2. Dependent variables

3.5.3.2.1. An attribute or characteristic influenced by the independent variable

3.5.3.2.2. What outcomes in my study am I trying to explain? ask yourself, “What is the outcome in this study?”

3.5.3.2.3. To locate dependent variables in a study, examine purpose statements, research questions, and hypotheses for outcomes that the researcher wishes to predict or explain.

3.5.3.3. Example

3.5.3.3.1. Probable Case

3.6. Theories and Testing of Variables (Steps we follow with the list of variables we found related to our research)

3.6.1. First step is describing variables

3.6.2. Test the relationship between variables

3.6.3. Probable cause establishes likely cause-and-effect

3.6.4. Theories predict relationships to test

3.6.5. Theories as Bridges between Independent and Dependent Variables

3.6.5.1. We trying to understand the relationship between Independent Variable and Dependent Variable, we build a bridge of "Theory"

3.6.5.1.1. Independent Variable

3.6.5.2. Theory

3.6.5.2.1. As a formal theory that is expressed by connected hypotheses and variables identified by authors

3.6.5.2.2. As a conceptual framework often expressed as a visual model by other authors for relationship

3.6.5.2.3. As a theoretical rationale posed by other authors based on studies for relationship

3.6.5.2.4. An explanation posed by the author as a hunch for why independent variable relates to dependent variable

4. Qualitative Reerach (Purpose Statements and Research Questions?)

4.1. Quantitative Research vs. Qualitative Research

4.1.1. Quantitative—more closed

4.1.1.1. Probable cause/effect (“Why did it happen?”)

4.1.1.2. Use of theories (“Why did it happen in view of an explanation or theory?”)

4.1.1.3. Assess differences and magnitude (“How much happened?”) (“How many times did it happen?”) (“What were the differences among groups in what happened?”)

4.1.1.4. Explaining or Predicting variables

4.1.2. Qualitative—more open-ended

4.1.2.1. Descriptive (“What happened?”)

4.1.2.2. Interpretive (“What was the meaning to people of what happened?”)

4.1.2.3. A Central Phenomenon

4.1.2.3.1. Concept or a process explored in qualitative research

4.1.2.3.2. Focus on a single concept or process

4.1.2.3.3. Example:

4.1.2.4. Process-oriented (“What happened over time?”)

4.2. Emerging Processes in Qualitative Research

4.2.1. Qualitative research is an emerging design

4.2.2. Purpose statements and research questions may change

4.2.3. Feedback and responses of participants inform changes

4.2.4. Example

4.3. Writing Qualitative Research Questions: Guidelines

4.3.3.1.1. Example

4.3.4. Issue subquestions: Narrow the focus of the central question into specific issues.

4.3.4.1. Central question:

4.3.4.1.1. What does it mean to be a professional teacher?

4.3.4.2. Issue subquestions:

4.3.4.2.1. What do professional teachers do?

4.3.4.2.2. What is difficult/easy about being a professional educator?

4.3.5. Writing Qualitative Research Questions: Subquestions

4.3.5.1. Subquestions: Divides the central question into smaller, specific questions

4.3.5.1.1. Procedural subquestions: Indicate the steps to be used in analyzing the data in a qualitative study.
