opportunity. Defining and describing a case study is a difficult task. Lincoln and Guba
(1985) acknowledge the difficulty in describing a case study when they write, ‘while the
literature is replete with references to case studies and with examples of case study
reports, there seems to be little agreement about what a case study is’ (p. 360). Gillham
(2000) provides a detailed definition of case studies;
A case study is one which investigates the above [a group
such as a family,
class, office, hospital ward, institution or large scale community] to answer
specific research questions (that may be very loose to begin with) and seeks a
range of different evidence, evidence which is there in the case setting, and
which has to be abstracted and collated to get the best possible answers to the
research question. No one kind or source of evidence is likely to be sufficient
(or sufficiently valid) on its own right. This use of multiple sources of evidence,
each with
its strengths and weaknesses, is a key characteristic of case study
research.’ (p. 1-2)
Many authors have classified case studies in to various categories. Stake (2000)
identifies two types of case study, intrinsic – which focuses on the individual case and
instrumental – which studies a number of cases to understand a wider puzzlement.
Stenhouse (1985) identified four categories: a. ethnographic case study – a single case
studied in its own right through participant observation and interview; b. evaluative case
study – which aims to provide an evaluation of policies and programmes for example
and may be single or a collection of cases; c. educational case study - which aims to ‘
enrich the thinking and discourses of educators whether by the development of
educational theory or by the refinement of prudence through
systematic and reflective
documentation of evidence’ (p. 49); d. action research case study – which is concerned
with the development of a case through feedback of information which can inform
revision or refinement of the action. Yin’s (1993) categorisation is similar but contains
only three categories: a. an exploratory case study aimed at defining the questions and
hypotheses of a subsequent study; b. a descriptive case study which describes the
phenomenon in its own context and c. an explanatory case study which data bearing on
a cause-effect relationship – explaining which causes produced which effects. These
categories help locate the key features of case study and provide a framework for this
research. The use of the term ‘case study’ in this study has features of Stenhouse’s
(1985) educational and evaluative studies and Yin’s (1993) descriptive case study.
Thus
various methods were employed, description and explanation sought, data
analysed and themes developed and the case studied to shed light on the research
questions.

Thus for the purposes of this study the case is taken to mean a particular school,
an urban, mixed gender, primary school [teachers: N=28 (year 1), N=27 (year 2) and
pupils: N=780 (year 1), N=800 (year 2)] the school community of Principal, teachers
and pupils and the variables that construct physical education and professional
development in physical education in the school and its wider social context. A mixture
of qualitative and quantitative research methods including interviews,
focus group
discussions, observations, teacher lesson evaluations, questionnaires, self-efficacy
questionnaires and physical measurements were used during the study.
The study was divided into four consecutive phases, each of which informed the
next phase of the research. The study concluded with an evaluation of the overall
professional development programme on completion. Although much of the research
design was established prior to its inception, aspects were ‘emergent’ (Guba and
Lincoln, 1985). The emergent research design was primarily associated with the
programme itself, and the methods of data collection that were used.
The research
design provided a firm structure within which the methodology remained flexible and
was changed relatively easily.
