Characteristics of qualitative Characteristics of qualitative research research
Natural settings - field research Natural settings - field research – Behavior is studied as it occurs naturally Behavior is studied as it occurs naturally – Beliefs related to a natural setting Beliefs related to a natural setting
Behavior is understood bests as it occurs Behavior is understood bests as it occurs without external constraints or control without external constraints or control
The situational context is very important to The situational context is very important to understanding behaviorunderstanding behavior
Characteristics of qualitative Characteristics of qualitative researchresearch
Data collection - data is collected directly Data collection - data is collected directly from the source from the source – Observations Observations – Interviews Interviews – Document analysis Document analysis
Characteristics of qualitative Characteristics of qualitative researchresearch
Rich narrative descriptions Rich narrative descriptions Process orientation - how and why Process orientation - how and why behaviors occur behaviors occur Inductive data analysis Inductive data analysis Participant perspectives define what is Participant perspectives define what is "real" "real" Emerging research design - the design Emerging research design - the design plans change as data is collected, plans change as data is collected, analyzed, and understood analyzed, and understood
Characteristics of qualitative Characteristics of qualitative researchresearch
Four type of qualitative designs Four type of qualitative designs – EthnographyEthnography – Case studyCase study – PhenomenologyPhenomenology – Grounded theoryGrounded theory
Assumptions that differentiate Assumptions that differentiate qualitative and quantitative studies qualitative and quantitative studies
Epistemology Epistemology – Qualitative researchers believe there are Qualitative researchers believe there are
multiple realities represented by the multiple realities represented by the participants' perspectives participants' perspectives
– Quantitative researchers believe a single, Quantitative researchers believe a single, objective reality exists objective reality exists
Assumptions that differentiate Assumptions that differentiate qualitative and quantitative studiesqualitative and quantitative studiesContext Context – Qualitative researchers believe context is critical to Qualitative researchers believe context is critical to
understanding the phenomena being studied understanding the phenomena being studied – Quantitative researchers do not believe context is an Quantitative researchers do not believe context is an
important factimportant fact
Researcher bias Researcher bias – Qualitative researchers believe the researcher's Qualitative researchers believe the researcher's
biases and perspectives must be understood to biases and perspectives must be understood to interpret the results interpret the results
– Quantitative researchers believe researcher bias is Quantitative researchers believe researcher bias is controlled through the control of internal validity controlled through the control of internal validity threats threats
Ethnography Ethnography
An ethnography is an in-depth description An ethnography is an in-depth description and interpretation of cultural patterns and and interpretation of cultural patterns and meanings within a culture or social group meanings within a culture or social group – Culture - shared patterns of beliefs, normative Culture - shared patterns of beliefs, normative
expectations, behaviors, and meanings expectations, behaviors, and meanings – SharedShared, not individualistic , not individualistic
Examples of ethnography: Peshkin and Examples of ethnography: Peshkin and Boaler studies. Boaler studies.
EthnographyEthnographyProblem statements Problem statements – Foreshadowed problem - a general framework for Foreshadowed problem - a general framework for
beginning a qualitative study beginning a qualitative study – Specific question - a question(s) that emerge from the Specific question - a question(s) that emerge from the
interactive relationship between the problem and data interactive relationship between the problem and data
Identifying and entering the research site Identifying and entering the research site – Access to all parts of the site (e.g., the participants, Access to all parts of the site (e.g., the participants,
documents, physical locations, etc.) documents, physical locations, etc.) – Rapport - need to be "integrated" within the site to Rapport - need to be "integrated" within the site to
gain the trust of the participants gain the trust of the participants – Often site entry takes a long time Often site entry takes a long time
EthnographyEthnographySelecting participants Selecting participants Use of purposeful sampling strategies to select Use of purposeful sampling strategies to select "information rich" participants "information rich" participants Purposeful sampling strategies Purposeful sampling strategies – Maximum variation - selecting individuals or cases to Maximum variation - selecting individuals or cases to
represent extremes (e.g., very positive or very represent extremes (e.g., very positive or very negative attitudes, highest and lowest achieving negative attitudes, highest and lowest achieving students) students)
– Snowball (i.e., network) - initially selected participants Snowball (i.e., network) - initially selected participants recommend others for involvement recommend others for involvement
– Sampling by case - selecting individuals or cases for Sampling by case - selecting individuals or cases for their unique characteristics their unique characteristics
– Key informant - selecting an individual(s) particularly Key informant - selecting an individual(s) particularly knowledgeable about the setting and or topic knowledgeable about the setting and or topic
EthnographyEthnographyObservation Observation – Unstructured in nature Unstructured in nature – Comprehensive - continuous and total over an Comprehensive - continuous and total over an
extended period of time extended period of time – Participant-observer role of the researcher Participant-observer role of the researcher
Use of field notes to record observations Use of field notes to record observations -- Descriptions of what occurred Descriptions of what occurred – Reflections of what the descriptions mean Reflections of what the descriptions mean
(i.e., speculations, emerging themes, (i.e., speculations, emerging themes, patterns, problems) patterns, problems)
EthnographyEthnography
Interviews Interviews – Unstructured in nature Unstructured in nature – Begins with a general idea of what needs to Begins with a general idea of what needs to
be asked and moves to specific questions be asked and moves to specific questions based on what the respondent says based on what the respondent says
– Tape recording and transcribing interviews Tape recording and transcribing interviews afford the opportunity to study the data afford the opportunity to study the data carefully carefully
EthnographyEthnography
Document analysis Document analysis Written records Written records – Print (e.g., minutes from meetings, reports, Print (e.g., minutes from meetings, reports,
yearbooks, articles, diaries) yearbooks, articles, diaries) – Non-print (e.g., recordings, videotapes, Non-print (e.g., recordings, videotapes,
pictures) pictures)
Types of sources Types of sources – Primary - original work Primary - original work – Secondary - secondhand interpretations of Secondary - secondhand interpretations of
original work original work
EthnographyEthnography
Data analysis Data analysis – Observations, interviews, and document Observations, interviews, and document
analyses result in large quantities of narrative analyses result in large quantities of narrative data data
– Analysis includes critically examining, Analysis includes critically examining, summarizing, and synthesizing the data summarizing, and synthesizing the data
EthnographyEthnographyThree stages of analysis Three stages of analysis – Coding: Organizing the data into reasonable, Coding: Organizing the data into reasonable,
meaningful units that are coded with words or meaningful units that are coded with words or very short phrases that signify a category.very short phrases that signify a category.
– Summarizing the coded data: Examining all Summarizing the coded data: Examining all similarly coded data and summarizing it with a similarly coded data and summarizing it with a sentence or two that reflects its essence sentence or two that reflects its essence
– Pattern seeking and synthesizing: Pattern seeking and synthesizing: Synthesizing identifies the relationships Synthesizing identifies the relationships among the categories and patterns that among the categories and patterns that suggest generalization. The researcher suggest generalization. The researcher interprets findings inductively, synthesizes the interprets findings inductively, synthesizes the information, and draws inferences information, and draws inferences
