VALUES OF QUALITATIVE RESEARCH 4. Historical Research
Examines events of the past
Qualitative research approaches are based on a worldview Three (3) primary questions of history are:

4 QUALITATIVE PERSPECTIVE Gather Data
Describe, Analyze and Interpret Data
1. Phenomenological Research Develop Written Report of the Results
Phenomena are the world of experience and they
occur only when a person experiences them SUMMARY
Phenomenology refers to both a philosophy and a
group of research methods congruent with the
philosophy
Phenomenologists view the person as integrated with
the environment
“What is the meaning of one’s lived experience?”
Understanding human behavior or experience,
requires the person to interpret the action or
experience for the researcher and then the researcher
must then interpret the explanation provided by the
person
2. Grounded Theory Research
Inductive technique that emerged from the discipline
of sociology
“Grounded” means that the theory that developed
from the research has its roots in the data from which
it was derived
Based on symbolic interaction theory which explores
how people define reality and how their beliefs are
related to actions.
George Herbert Mead (1934), a social psychologist
was a leader in the development of this theory
Grounded theory researcher seeks to understand the
interaction between self and group from the
perspective of those involved.
3. Ethnographic Research
Developed by anthropologists to study cultures
through immersion in the culture for a significant
period of time
“Ethnography” means “portrait of a people”.
Study a people’s origins, past ways of living, and
ways of surviving through time
