QUALITATIVE RESEARCHAgenda Definition When to use? TypesFOCUS GROUPS IN DEPTH INTERVIEW PROJECTIVE TECH.

Research used in range of activities from exploratory designs to means of completing explanations Qualitative research assumes that people have meaningful actions or experiences that can be interpreted

Pros&Cons

QUALITATIVE RESEARCH Identification of a given question; opportunity or information requirements Interest in obtaining insights for motivational /social (group) or emotional and attitudinal (individual) factors In IR: primary data of events or personalities supporting explanations and argument (Cf. In marketing: for new product launch, new service development or repositioning current product

QUALITATIVE RESEARCH DESIGNQualitative Research: Examples Case studies on effect of vocational training in Papua Ethnographic studies on indigenous populations in Oaxaca, Mexico Qualitative Research Types: Case studies Developmental research Historical research Ethnograph studies Case Studies: Purpose: to do an in depth study In brief: Background, current status and/or environmental factors that interact for each group (individual, institution or community)

Characteristics of Case Studies: It gives very detailed information about individuals / group / community It may give a detailed explanation of a complete life cycle or part of it Number of cases studied may be small but the number of variables studied are usually more in-depth (e.g. if compared to a survey) Developmental Research: Conducted to research on the development of individuals / group / institution / community TWO TYPES: Cross-sectional and Longitudinal Historical Research: Used to gain information on an event, development and/or previous educational experience Process may involve studying previous situation, checking on current situation, and to predict if the same situation will occur again Conclusion on previous event is done based on collected facts and evidences to answer why and how the event and repercussions occurred Useful to solve questions that involve sensitive issues Important for systematically & objectively collecting and defining facts and evidences

Procedure for Historical Research: Define the problem Specify source of evidence Collect evidence / reference materials Primary source / original (observation or witnesses of events or authentic objects e.g. artifacts, speech text, records etc.) Secondary source (materials or information collected from primary sources e.g. paintings, films, news reports, documents Critique of evidences External critique: confirming if collected sources are genuine and reliable (authenticity of paintings, signatures, chemical analysis etc.) Internal critique: conducted after authenticity of source of information is confirmed involves evaluation of collected evidences is it important? Required?

Able to explain the researched phenomenon? Prepare the report Ethnographic Research: In-depth study of natural behaviours in a culture or social group Purpose to understand relationships between behaviour and culture Example: In education to understand schooling process (e.g., immigrant children) Involves widespread observations (participant & nonparticipant)

Here often starts research without hypothesis hypothesis is developed in the process of observations, and the researcher explores and test his hypothesis

QUALITATIVE RESEARCH IN-DEPTH INTERVIEWCharacteristics:Agenda Definition When to use? TypesFOCUS GROUPS IN DEPTH INTERVIEW PROJECTIVE TECH.

A well trained interviewer+interviewee Interviewee is exposed to set of probing questions Usually face to face Interviewer encourages the interviewee to talk more

Goal: To collect as much as memory, attitudinal and behavioral data from the subject

Pros&Cons

QUALITATIVE RESEARCH IN-DEPTH INTERVIEWApplications:-Interviews with professionals -Interviews with witnesses -When detailed probing is needed -Discussion of sensitive, confidential issues -When strong, social norms exist -Interviews with competitors

QUALITATIVE RESEARCH IN-DEPTH INTERVIEWADVANTAGESConcentrated

DISADVANTAGESExpensive

issue maximum probing Free exchange of information Easier to arrange Best for intimate, sensitive issues Flexibility

Time

consuming Exhausting for Interviewer Interviewer errors Respondent bias or reliability

QUALITATIVE RESEARCH PROJECTIVE TECHNIQUEDefinition:*Agenda Definition When to use? TypesFOCUS GROUPS IN DEPTH INTERVIEW PROJECTIVE TECH.

These are unstructured prompts or stimulus that encourage the respondent to project their underlying motivations, beliefs, attitudes, or feelings onto an ambiguous situation They are all indirect techniques that attempt to disguise the purpose of the research
