A s pointed out in my Introduction to this Special Issue, there have been various reasons for the recent increasing interest in researching and reforming professional practice. A major reason is our limited understanding of the nature of professional practice itself. Professional practice is a typical interdisciplinary topic which can be viewed, and has been viewed, from the perspective of a variety of disciplines and fields, such as sociology, cognitive psychology, philosophy, management theory, economics, and learning theory. As well, there are various literatures which are arguably relevant to an understanding of professional practice, even though their main foci are somewhat different. These include research on the nature of expertise, on workplace learning, on situated learning, etc. Hence research on professional practice represents a convergence of rather diverse literatures. This paper will provide a brief critical outline of the main findings of some of these relevant literatures and a discussion of the implications of these overall findings for professional practice. Schon (1983Schon ( , 1987 has been a particularly influential entre of traditional approaches to and assumptions about professional education. The failure of theory/practice ways of conceptualising the problem has generated a host of attempts in more recent work to bypass this dichotomous approach. These range from Schon's 'reflective practitioner' to problem-based learning. The impact of this thinking has been very widespread. Even in cognitive psychology, there is a recognition of the need to 'de-emphasise the spurious theory-and-practice connotations' that surround the declarative knowledge/procedural knowledge and similar distinctions because 'they do not necessarily represent independent modes offunctioning' (Yates & Chandler, 1991, pp. 133-134).
Recent research on professional practiceSchon's proposed alternative epistemology of professional practice centres on the 'reflective practitioner' who exhibits 'knowing-in-action' and 'reflectingin-action'. Knowing-in-action is tacit knowledge in that, though practitioners know it, they cannot express it. Thus it is akin to Polanyi's (1958) 'personal knowledge' which refers to the type of know how that is displayed in skilful performances which can be seen to follow a set of rules that is not known as such to the performer. According to Schon, knowing-in-action is underpinned by 'reflecting-in-action' or 'reflecting-in-practice'. This spontaneous reflecting is
