This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals.

Summary In several places Popper describes a little experiment in which an audience is given the non-specific command ‚Observe!‘ He draws a number of conclusions from this experiment, in particular that observation takes place in the presence of theoretical problems, questions, hypotheses or points of view. The paper argues that while Popper's experiment is instructive, it hardly supports the strong conclusions he draws about the theory-dominance of observation in science. In particular, it is argued that talk of principles of selection which guide us to relevant observations, rather than the host of irrelevant observations of the naive inductivist, is misleading. Rather, it is the goals, aims, motives or interests of an observer that guide observation and these need not always involve a theoretical component

Kripke and Putnam have proposed that terms may be introduced to refer to theoretical entities by means of causal descriptions such as 'whatever causes observable effects O'. It is argued that such a reference-fixing definition is ill-formed and that theoretical beliefs must be involved in fixing the reference of a theoretical term. Some examples of reference-fixing are discussed e.g., the term 'electricity'. The Kripke-Putnam theory can not give an account of how terms may be introduced into science and then subsequently be discovered to be non-referring. A modified account of reference-fixing is suggested in which terms such as Gilbert's electric effluvia' and 'phlogiston' can be introduced into science and then be found to lack a reference

These three volumes are amongst the first of a series of anthologies of philosophical writings under the title Oxford Readings in Philosophy, the series editor being G J Warnock. The blurb on the back of each says that ‘the aim of this series is to bring together important recent writings in major areas of philosophical inquiry, selected from a variety of sources, mostly periodicals, which may not be conveniently available to the university student or the general reader’. But all good anthologists have at least this in mind. Hence the glut of anthologies and the reduplication of articles belying the aims of anthologists.

Normative naturalism (NN), advocated by Larry Laudan, understands the principles of scientific method to be akin to scientific hypotheses which are then open to test like any principles of science. It uses a meta-inductive rule to test methodological principles against suitably presented episodes in the history of science. One strength of NN is that it provides the basis for a philosophical/historical research programme into the methodological strategies actually employed in the sciences. But for the philosopher interested in the grounds of scientific rationality NN is not without it difficulties such as: it adopts a strongly empiricist account of meta-method which rules out realist principles of scientific method from the test procedures; it uses principles of test which are either not agreed upon, or stray from the meta-inductive rule; it reveals its limits in presupposing answers, rather than offering solutions, to problems of scientific rationality.

Many philosophical naturalists eschew analysis in favor of discovering metaphysical truths from the a posteriori, contending that analysis does not lead to philosophical insight. A countercurrent to this approach seeks to reconcile a certain account of conceptual analysis with philosophical naturalism; prominent and influential proponents of this methodology include the late David Lewis, Frank Jackson, Michael Smith, Philip Pettit, and David Armstrong. Naturalistic analysis (sometimes known as "the Canberra Plan" because many of its proponents have been associated with Australian National University in Canberra) is a tool for locating in the scientifically given world objects and properties we quantify over in everyday discourse. This collection gathers work from a range of prominent philosophers who are working within this tradition, offering important new work as well as critical evaluations of the methodology. Its centerpiece is an important posthumous paper by David Lewis, "Ramseyan Humility," published here for the first time. The contributors first address issues of philosophy of mind, semantics, and the new methodology's a priori character, then turn to matters of metaphysics, and finally consider problems regarding normativity. Conceptual Analysis and Philosophical Naturalism is one of the first efforts to apply this approach to such a wide range of philosophical issues. _Contributors: _David Braddon-Mitchell, Mark Colyvan, Frank Jackson, Justine Kingsbury, Fred Kroon, David Lewis, Dustin Locke, Kelby Mason, Jonathan McKeown-Green, Peter Menzies, Robert Nola, Daniel Nolan, Philip Pettit, Huw Price, Denis Robinson, Steve Stich, Daniel Stoljar The hardcover edition does not include a dust jacket.

Foucault appears to challenge traditional views of truth, reason, and knowledge in the doctrine of power/knowledge developed in his post‐1970 writings. This doctrine applies to all the sciences (and to non‐scientific and non‐discursive practices that are not discussed here). Foucault's notions of discourse (1) and power (3) are sufficiently discussed to set out his explanatory theory of the cause of our discourses and their change. In (4) three theses concerning the power/knowledge link are distinguished, of which the more important is called the ‘Primacy Thesis’, namely the causal priority of power over knowledge. Various formulations of this thesis are investigated, some of which are contrasted with Francis Bacon's more plausible account of the link between power and knowledge. In (5), six criticisms of the thesis are discussed. Foucault's notion of truth is explored on the way, more particularly in (6). The outcome of the discussion is that Foucault's doctrine of power/knowledge, apart from some insights for an empirically based sociological investigation into the causes of some of our scientific beliefs, is generally false; for philosophical theories of truth and knowledge it has nothing to say. In fact if Foucault is to be a critic of the beliefs which circulate as a result of power, he needs the traditional account of truth and knowledge.

The institutionalization of History and Philosophy of Science as a distinct field of scholarly endeavour began comparatively earl- though not always under that name - in the Australasian region. An initial lecturing appointment was made at the University of Melbourne immediately after the Second World War, in 1946, and other appoint ments followed as the subject underwent an expansion during the 1950s and 1960s similar to that which took place in other parts of the world. Today there are major Departments at the University of Melbourne, the University of New South Wales and the University of Wollongong, and smaller groups active in many other parts of Australia and in New Zealand. "Australasian Studies in History and Philosophy of Science" aims to provide a distinctive publication outlet for Australian and New Zealand scholars working in the general area of history, philosophy and social studies of science. Each volume comprises a group of essays on a connected theme, edited by an Australian or a New Zealander with special expertise in that particular area. Papers address general issues, however, rather than local ones; parochial topics are avoided. Further more, though in each volume a majority of the contributors is from Australia or New Zealand, contributions from elsewhere are by no means ruled out. Quite the reverse, in fact - they are actively encour aged wherever appropriate to the balance of the volume in question.
