Our research addresses the issue of teaching and learning concepts in science education as an empirical question. We study the process of conceptualization by closely examining the unfolding of classroom lesson sequences. We situate our work within the practice turn line of research on epistemic practices in science education. We also adopt a practice turn approach when it comes to the learning of concepts, as we consider conceptualization as being inherent within epistemic practices. In our work, pedagogical practices are modeled (...) as learning games and epistemic practices in science education are characterized as enacted epistemic games emerging through the unfolding of learning games. Science practices are modeled as source epistemic games since they are the source of the knowledge at stake in pedagogical practices. From this point, we examine closely how playing learning games can enable students to play enacted epistemic games and then in turn the source epistemic games at the core of conceptual understanding. Thus, the main contribution of this paper is to link pedagogical practices to epistemic practices in science education and to science practices in general. Our method is consistent with this epistemological framework as our case study on the concept of earthquakes in a 5th grade classroom sequence illustrates. Following an investigation of two experienced teachers and their classes during a teaching unit, our analysis shows how teaching effectiveness is determined by a dialectic. This entails on the one hand a didactic continuity between learning games and enacted epistemic games and, on the other, an epistemic continuity between enacted epistemic games and source epistemic games.

In the first part of this article, I argue that Christopher Megone's natural-kind interpretation of Aristotle's argument that "the function of a human being is reason" does not resolve major puzzles about the argument, specifically the puzzles of why a human being has a function and why reason is that function. I attempt to resolve these puzzles by supplementing the natural-kind account with the doctrine that reason is the master regulatory natural function by which individuals enter into social life. In (...) the second half, I critique Megone's value account of function and argue for a nonevaluative, causal-explanatory account of function and teleological explanation. (shrink)

We settle a number of questions concerning definability in first order logic with an extra predicate symbol ranging over semi-linear sets. We give new results both on the positive and negative side: we show that in first-order logic one cannot query a semi-linear set as to whether or not it contains a line, or whether or not it contains the line segment between two given points. However, we show that some of these queries become definable if one makes small restrictions (...) on the semi-linear sets considered. (shrink)

Les critiques actuelles des diagnostics psychiatriques, qu’elles viennent des antipsychiatres, des béhavioristes, des constructionnistes sociaux, des szasziens et des foucaldiens, rejettent généralement l’idée que le concept de trouble mental est légitime du point de vue médical, ne laissant donc aucun argument solide à partir duquel il soit possible de mener une critique constructive et d’établir un dialogue avec la psychiatrie. Ces positions ne réussissent également pas à expliquer les fortes intuitions populaires qui permettent aux gens de distinguer les troubles psychologiques (...) des autres conditions psychologiques négatives. Selon l’analyse de la dysfonction préjudiciable présentée dans cet article, un trouble mental est une condition : 1) préjudiciable, un concept évaluatif basé sur des valeurs sociales ; et 2) causée par une dysfonction psychologique, un concept factuel se rapportant à un mécanisme psychologique qui accomplit une fonction pour laquelle il a été biologiquement conçu . L’analyse DP est ainsi une position hybride qui requiert à la fois que des critères évaluatifs et factuels soient satisfaits pour garantir l’attribution d’un trouble. Nous argumentons que l’analyse DP réussit admirablement à expliquer les jugements intuitifs quant à ce qui est un trouble et à ce qui en n’est pas. La composante factuelle permet également de critiquer le critère diagnostique du DSM, ce que nous ferons à l’aide de plusieurs exemples . Ces critiques déterminent où le DSM a dévié de ses propres hypothèses et ainsi considéré comme des troubles ce qui n’en est pas. Elles expliquent également pourquoi les tentatives du DSM de remédier au problème en introduisant le critère du « cliniquement significatif » échouent.Current antipsychiatric, behaviorist, social-constructivist, Szaszian, and Foucauldian critiques of psychiatric diagnosis generally reject mental disorder as a medically legitimate concept, thus allowing no place to stand from which to mount a constructive critique and dialogue with psychiatry. These views also fail to explain the robust folk intuitions by which people distinguish psychological disorders from other negative psychological conditions. According to the harmful dysfunction analysis presented in this paper, a mental disorder is condition that is harmful, a value concept judged by social values ; and caused by a psychological dysfunction, a factual concept referring to failure of a psychological mechanism to perform a function for which it is biologically designed . The HD analysis is thus a hybrid account that requires both value and factual criteria to be satisfied before attribution of disorder is warranted. It is argued that the HD analysis has considerable success in explaining intuitive judgments about disorder versus non-disorder. The factual component also allows for a critique of DSM diagnostic criteria for specific categories, with several examples discussed. These critiques identify where the DSM has deviated from its own deepest assumptions and labeled non-disorders as disorders, and why the DSM’s own attempts to fix the problem, as with the «clinical significance» criterion, do not succeed.

This work exposes the practices that are controlling education and reducing it to little more than skills development in preparation for work. It questions the strategy of mentoring to show how its dynamic requires docility from the learner and thus perpetuates inequality.

This research questions the prevention and health promotion practices developed for young people, in France, and re-examines the nature of competences enlisted in the classical model of empowerment in health education. Moving away from the epidemiological postulate of evidence based medicine (EBM), it explores another approach of these educational practices. The research uses the perspective of narrative mediation; it tries also to identify issues about a better knowledge of oneself, making more comprehensive the issues of young students’ health.

There are different ways to consider the movement of the part-time theater and audiovisual workers, or intermittents. A classic, distanced way, sees a professional group protecting its rights and ideologies in the face of an unemployment reform presented as a campaign against cheats. Or a more inward and forward-looking way, showing the movement’s productivity, what it is symptomatic of, how it foreshadows a deeper political transformation. Intermittence is a particular seismic zone between two tectonic plates of our values: culture and (...) labor. Questions of employment practices, subjective relations to time, discontinuity of activity and creative process, more than exchanges of opinions about high culture, are what have allowed the movement to persist, construct and propose.The many additional human and circumstantial ingredients have finally brought forth, at least in our minds, the idea of a particular emergence of law and of common things. Still fragile and relative, this emergent juncture leads us to a fresh questioning of the public debate via another process of work, elaboration and creativity around the lived substance of things, and not only of their symbolic representations. A process which is the intermittent’s daily condition, one which could unexpectedly lead to a transformation of politics, via the obligation to approach all these common things differently. These common things whose very process of emergence seems to be transforming. (shrink)

This book persuasively shows that modern philosophical ways of knowing are not the only valid forms of knowledge that exist. Angela Roothaan argues for a critical reappraisal of indigenous ways of knowing and a need to overturn the politics of epistemology that sustain the modern system of knowledge with regard to its othering of indigenous outlooks of nature. According to Roothaan, this can be achieved by broadening our epistemological and moral vistas beyond the thin modern scientific view that circumscribes valid (...) knowledge merely to the empirical aspects of reality. Such broadening will make an intercultural environmental dialogue possible. (shrink)

First order reasoning about hyperintegers can prove things about sets of integers. In the author’s paper Nonstandard Arithmetic and Reverse Mathematics, Bulletin of Symbolic Logic 12 100–125, it was shown that each of the “big five” theories in reverse mathematics, including the base theory , has a natural nonstandard counterpart. But the counterpart of has a defect: it does not imply the Standard Part Principle that a set exists if and only if it is coded by a hyperinteger. In this (...) paper we find another nonstandard counterpart, *RCA0′, that does imply the Standard Part Principle. (shrink)

Platon, dans les Lois, renonce au vocabulaire des « parties de l’âme » et souligne l’unité de l’activité psychique humaine: nous sommes mus de l’extérieur, comme une marionnette par des fils (I, 644c-645a). Comment comprendre la mollesse de l’or et la dureté du fer dont il est alors question? Y a-t-il nécessairement conflit entre ces différentes impulsions?

Strabon n'est pas un philosophe stoïcien. En relisant l'ensemble de la Géographie, les traits stoïciens de sa méthode, de sa physique et de sa conception de l'existence humaine apparaissent bien minces. Il semble donc préférable de voir en lui un penseur éclectique dont le but principal est la description rigoureuse du monde habité.Strabo is not stoic philosopher. His Geography, his Method, his Physics and his conception of human life do not come across as not strongly stoic when they are patiently (...) read. It seems more appropriate to view him as an eclectic thinker whose main objective is the rigorous description of the inhabited world. (shrink)

What does "The Rime of the Ancient Mariner" mean? This question, in one form or another, has been asked of the poem from the beginning; indeed, so interesting and so dominant has this question been that Coleridge's poem now serves as one of our culture's standard texts for introducing students to poetic interpretation. The question has been, and still is, an important one, and I shall try to present here yet another answer to it. My approach, however, will differ slightly (...) from the traditional ones, for I do not believe that we can arrive at a synthetic answer until we reflect upon the meaning of the question itself. I will begin, therefore, by reconsidering briefly the history of the poem's criticism. . . . A poem like the "Rime" encourages, therefore, the most diverse readings and interpretations. Since this encouragement is made in terms of the Christian economy, the interpretations have generally remained within the broad spiritualist terms, "heathen" terms, in Newman's view, which Coleridge's mind had allowed for. The historical method of the "Rime," however, had also prepared the ground for a thoroughly revisionist view of the poem, in which the entire ideological structure of its symbolist procedures would finally be able to be seen in their special historical terms.
