Case Study
. A case study aims to understand a case in depth, and in context
recognising its complexity, which suits the case of a single primary school, as in this
study. Case studies are prevalent throughout the field of education (Merriam, 1998).
Yin (1994) defines a case study as, ‘an empirical inquiry that investigates a
contemporary phenomenon
within its real life context, especially when boundaries
between phenomenon and context are not clearly evident’ (p. 13). Miles and Huberman
(1994) think of a case as a ‘phenomenon of some sort occurring in a bounded context’
(p. 25). This methodology was deemed the most appropriate for this study. The
bounded context, or case was established as the school context, limited by the teachers,
children and the school principal. The case was also bounded by the fact that the
phenomenon to be studied, teachers’ and children’s experiences of a contextualised,
whole school professional development programme was over
a finite amount of time,
i.e. the preparation, design and implementation of the professional development
programme. The case study approach allows for multiple methods of data collection,
and although seen mainly as a qualitative methodology, quantitative methods of data
collection are not discarded.
Case study is a suitable research methodology when a researcher is interested in
process, an outcome of this study. The case study focuses on holistic description and
explanation (Merriam, 1998), process meaning, describing the
context and study
population, discovering the extent to which a programme is implemented, explaining
the cause of the process and its effect or impact (Stake, 1995), which aligns with the
research questions of this study. There are many different types of case study;
exploratory, descriptive, explanatory (Yin, 1994); descriptive, interpretative and
evaluative (Merriam, 1988); ethnographic, action
research, evaluative and educational
(Sturman, 1999); and intrinsic, instrumental and collective (Stake, 1994). According to
Merriam (1998), case studies are useful when presenting information about innovative
practices and programmes where little research has been conducted in the past. These
studies may then in the future provide a baseline or database for comparative studies,
and play an important role in advancing a field’s knowledge base. Because of these
strengths and the fact that very little research has been carried
out in an Irish whole
school context of professional development, case study is the most appealing
methodology for this study. The professional development programme at the heart of
this study can be examined to bring about understanding which may in turn affect and
bring about change in practice. Constructivism allows the researcher justify lots of
15
description in the reporting of the study (Stake, 1995). In this study the researcher is the
primary instrument of data gathering and analysis and is left
primarily to their own
instinct and ability throughout the process. Although, this may be a limitation of a case
study, in the research design and methods of data collection and analysis precautionary
steps were taken to ensure the integrity of the researcher and the methods of collection
and analysis at all times. Following a constructivist view of knowledge does not require
the researcher to avoid generalisations, as is sometimes pointed
to as a limitation of case
studies, but in this case should provide readers with good information for their own
generalising. The case study methodology is described further in chapter three –
Research Design.
