This document discusses different research approaches including quantitative, qualitative, and mixed methods. It provides details on the three components involved in each approach: philosophical worldviews, research designs, and specific research methods. As an example, a quantitative approach may use a post-positivist worldview, experimental design, and pretest/posttest measures. A qualitative approach could use a constructivist worldview, ethnographic design, and observation. A mixed methods approach may use a pragmatic worldview and collect both quantitative and qualitative data sequentially. The document emphasizes that the research problem and questions should determine which approach is best.

5. Qualitative research
1. Exploring, understanding
and ascribing individual or
social problem.
2. data typically collected
in the participant’s setting.
3. Data analysis inductively.
4. Writing report has a
flexible structure
Quantitative research
1. for testing objective
theories .
2. Examining the relationship
between variables.
3. Data analysis deductively
4. Written report has a fixed
structure.
1. integrating the two forms
of QUAL and QUAN data.
2. Using distinctive design for
each philosophical
assumptions.
3. Provide information
beyond QUAL and QUAN data
alone

6. Three Components Involved in each Approach
Specific research methods:(questions,
data collection, data analysis,
interpretation and validation)
Philosophical worldviews:
(post-positivist, constructivist,
transformative and pragmatic)
Research designs:
(quantitative for example; experiments),
(ethnographies for example; ethnographies)
and (mixed methods for example explanatory
sequential)

10. Research Approaches as Worldviews, Designs, and Methods
Research Approaches as Worldviews, Designs, and Methods
1. Quantitative approach;
Post-positivist worldview, experimental design, and pretest and posttest measures of
attitudes.
2. Qualitative approach in two different ways;
A. Constructivist worldview, ethnographic design, and observation of behavior
B. Transformative worldview, narrative design, and open-ended interviewing
3. Mixed methods approach;
Pragmatic worldview, collection of both quantitative and qualitative data sequentially in the
design
11. The Research Problem and Questions
Quantitative approach is the best
The identification of factors that influence an outcome, The utility of an
intervention and understanding the best predictors of outcomes
Quantitative approach is the best
phenomenon needs to be explored and understood
may first survey a large number of individuals and then follow up with a few
participants to obtain
Mixed method approach is the best
