TRANSCRIPT
AIMS
• Explaining case study research (definition)
• Designing case studies (design)
• Conducting case studies (data collection)
• Analysing case study material (analysis)
• Group activity
DEFINITION
Qualitative and quantitative, but predominantly qualitative
‘In quantitative studies, the research question seeks out a relationship between a small number of variables...In qualitative studies, research questions typically orient to cases or phenomena, seeking patterns of unanticipated as well as expected relationships’
(Stake 1995, p. 41)
DEFINITION
• Underpinned by inductive reasoning
• Geared toward analytic generalization
• Focus on particularisation, not generalization
• Communicate experiential through narrative
• Why? Phenomenon and context are blurred
DEFINITION
‘In seeking absolute truth, we aim at the unattainable, and must be content with finding broken portions’
Sir William Osler
DESIGN
• Research aims/questions
• Rationalization and justification of aims
• Theoretical statements or propositions,
together with evidence of a theoretical
development or trajectory
• Single-case or multiple-case design
DESIGN
• Construct Validity - specification of meaning • Internal Validity - causal relationships• External Validity - analytic generalization• Reliability - correction or minimization of bias
(Yin 1994, p. 33)
DESIGN
• Embedded case study design - multiple subunits of analysis - multiple sources and types of evidence - multiple methods of data analysis
• Holistic case study design - single unit of data collection and analysis
CASE STUDY 1: SCHOOLOfficial school
documents, website material, prospectus, minutes, improvement
plans, achievement levels.
Mediating structures, e.g. school-to-school
partnerships, collaboration, local authority, MATs, co-
operative, etc.
Government and non-government texts, e.g.
DfE, Think Tank, Ofsted, academic, third sector
and media.
Observations of meetings, e.g. FGB, committee and PTA.
Interviews with (support) staff, parents, governors,
headteacher, etc.
DATA COLLECTION• Research process is not routinized but typically sporadic, non-linear and unpredictable
• Hallmarks of a good investigator - approachable and congenial - networks effectively and builds contacts - ethical and trustworthy - cognizant of relevant issues, language - good listener, asks probing questions - suspends conceptual baggage, e.g. is open minded
DATA COLLECTION
• Types and sources of data collection - Documentation - Archival records - Interviews - Direct or ‘detached’ observation - Participant-observation - Physical artefacts
DATA COLLECTION
• Triangulation or ‘converging lines of inquiry’ (Yin 1994, p. 92)
• Chain of evidence: ‘the principle is to allow an external observer...to follow the derivation of any evidence from initial research questions to ultimate case study conclusions’ (ibid, p. 98)
DATA ANALYSIS
Much qualitative data analysis hinges on
• ‘thick description’ - communicate experience of others• ‘experiential understanding’ - develop appropriate conceptual tools• ‘multiple realities’ - identify plurality of contexts
(Stake 1995: 43)
DATA ANALYSIS
Theory building and hypothesis testing
‘The gradual building of an explanation is similar to the process of refining a set of ideas in which an important aspect is again to entertain other plausible or rival explanations’
(Yin 1994: 111)
DATA ANALYSIS
Indicators of bad research
• Seeking out only confirmatory evidence• Biased and partial readings of selected texts
Indicators of good research
• Trustworthiness• Representativeness

GROUP ACTIVITY (15-20 mins)In pairs explore the extent to which a case study approach compliments or deviates from the scope of your research aims/interests.
Outline what you perceive to be its limitations and advantages in terms of furthering knowledge of your particular research area and its practical implications (e.g. for practitioners, policy makers.)
What are the units of analysis that would make up your single- or multiple-case study, and what kind of case study design would you deploy, e.g. holistic or embedded?
