These three models informed the design, operation and instructional strategies of
the professional development programme for this study and are aligned with the key
features of effective professional development underpinned by social constructivist
theory. They also ‘identify the variables that mediate (explain) and moderate (interact
or influence) professional development’s effects (Desimone, 2009, p. 184). Further
detail of how the pertinent characteristics from each of these models are incorporated
into the programme content, operation and instruction are outlined in chapter five.
Teacher Change
Professional development is comprised of and dependent on two theories: theory
of instruction (this has been explained in the previous section and is operationalised in
chapter five) and theory of change (Wayne et al, 2008). This section will deal with
theories of change that have informed professional development practice and research.
Bowring-Carr and West-Burnham (1999) stated that the only answer when faced with
continuous change is to keep learning. Change for teachers involves more than just
enhanced knowledge; it requires ‘a belief in the process itself and recognition that
renewal and development are essential’ it holds that ‘new behaviours and practices, and
ultimately new beliefs and understandings’ (Government of Ireland, 1999a, p. 62).
Fullan (1991) has written extensively on educational change and coined the phrase,
‘change is a process, not an event’ and suggested that ‘educational change is technically
simple and socially complex.’ Fullan (2001) also noted that ‘educational change
depends on what teachers do and what teachers think – it’s as simple and as complex as
that’ (p. 115). For some teachers change is a slow and uncertain process with some
elements of teachers’ knowledge and practice more easily changed than others through
professional development programmes (Franke, Carpenter, Levi & Fennema, 2001).
Avalos (2011) stated that cognitive theory and research have unveiled some of the
factors, such as how the role of beliefs and the perceptions of self-efficacy can support
or hinder change. From his research he found that diverse forms of professional
development have effects of some kind but unfortunately we know little about the
degree to which these efforts are sustained, though the more prolonged the professional
development intervention the more effective.
