There is an over-arching consensus that the use of the history of mathematics should decidedly improve the quality of mathematics teaching. Mathematicians and mathematics educators show here a rare unanimity. One deplores, however, and in a likewise general manner, the scarcity of positive examples of such a use. This paper analyses whether there are shortcomings in the—implicit or explicit—conceptual bases, which might cause the expectations not to be fulfilled. A largely common denominator of various approaches is some connection with the term “genetic.” The author discusses such conceptions from the point of view of a historian of mathematics who is keen to contribute to progress in mathematics education. For this aim, he explores methodological aspects of research into the history of mathematics, based on—as one of the reviewers appreciated—his “life long research.”  相似文献

Towards a research training curriculum: What, Why, How, Who?   总被引:3,自引:0,他引:3  
Our purpose in this paper is to investigate the ways in which the work of research higher degree supervision is being reshaped from within and outside universities. Our interest is in the means by which new ‘content’ and ‘process’ knowledge — and thus a new set of pedagogical tasks and relationships — are being configured in the field of higher degree research. The outcomes of research training have traditionally been products of a one-on-one supervisory relationship, that is, academic apprentice-to-disciplinary mentor. This is especially the case in the fields of arts/humanities. Any ‘curriculum’ necessary to such a model has been both implicit and at the discretion of the disciplinary ‘master’.  相似文献

In many real life situations, we have to draw conclusions from data which are not complete and have been affected by measurement errors. Such problems have been addressed from the time of Bayes and Laplace (late 1700’s) using concepts which parallel Boltzmann’s use of entropy in thermal physics. The idea is to assign probabilities to different possible conclusions from a given set of data. A critical — and sometimes controversial — input is a ‘prior probability’, which represents our knowledge before any data are given or taken! This body of ideas is introduced in this article with simple examples.  相似文献

In 1965, Arno Penzias and Robert Wilson of Bell Telephone Laboratories in USA discovered weak microwave radiation coming from all directions which was soon realised to be a relic from a hot dense early phase of our Universe—the ‘big bang’. This article focuses on the key experimental techniques and innovations which made this momentous—and accidental!—discovery possible. Amit Roy is at the Nuclear Science Centre, New Delhi, building a superconducting linac booster for the pelletron accelerator. He spent over two decades at the Tata Institute of Fundamental Research, Mumbai investigating nuclei using accelerators and probing symmetries in physics. His hobbies are books and music.  相似文献

This article describes the cultural consequences of the local school closing in a predominantly black community (Centerville) as a result of desegregation policies. Based on oral accounts of community members, the author unearths the diverse functions the former all-black school used to have in the community. Furthermore, the possible reasons for the nostalgia with which the community remembers its “own” school are analyzed. It is shown why the predominantly white schools to which today's students are bused cannot possibly “pass the test” of comparison with the former community school. And finally, the article reminds us of two promises ofBrown, only one of which has been fulfilled in the case of Centerville. While racial segregation of schooling was indeed abolished in Centerville, the second promise ofBrown—providing equal educational opportunities for all children irrespective of race—remains elusive at best. And the very institution that would be central to fulfilling the second promise ofBrown—a school for which the town feels a sense of ownership—was closed for the sake of desegregation. Parts of this article have been the basis for an oral presentation at the South Atlantic Philosophy of Education Society meeting, Richmond, VA, October 1993, and are published in the SAPES Proceedings, 1993, pp. 109–114.  相似文献

The paper analyses a form of interprofessional working and learning (IPWL)—the fleeting spatial and temporal constitution of project teams with little prior history of working together—that is an increasing feature of work in the global economy. The paper argues firstly: (i) this form of working and learning is relatively under-researched in professional, vocational and workplace learning (PVWL); and, (ii) the research traditions—Cultural-Historical Activity Theory (CHAT) and Cultural Anthropology/Symbolic Interactionist (CA/SI)—that some researchers in PVWL have drawn on to investigate IPWL do not allow them to capture the cognitive and symbolic complexity of this activity. Secondly, it is possible to reveal the nature of this complexity when the concepts and methods associated with CHAT and CA-SI-based approaches are supplemented with the concepts of ‘inference’, ‘space of reasons’, ‘restructuring and ‘recontextualisation’ (Guile, 2010). The paper demonstrates this claim by reinterpreting a classic study of the aforementioned form of working and learning undertaken by Hall, Stevens and Torolba that drew on concepts and methods from CA and SI (2002).  相似文献

The gravitational field of a massive, spherical, body like the Sun is described in general relativity by a solution to Einstein’s equations called the Schwarzschild soution. Here is an elementary persepective on this solution, which — though far from a rigourous derivation — raises intriguing questions. T Padmanabhan works at IUCAA, Pune and is interested in all areas of theoretical physics, especially those which have something to do with gravity. This is based on an article originally published by the author in Physics Education, Vol. 23, No.1, p.47, 2006.  相似文献

Authors of lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) adolescent novels have recently moved away from addressing the “problem” of sexual identity and have instead focused on personal and societal “acceptance” of non-normative sexualities. Within the increasing number of “acceptance” titles published depicting gay males, there are two distinct means of representing forms of gayness. In this article, I illustrate that what distinguishes these forms from one another is their handling of homophobia and the extent to which they subvert heteronormativity, the implicit belief that heterosexuality is the only “normal” self-identity. While some authors use homophobia as the foil against which queer characters struggle in order to find happiness as a couple, others work to suspend “reality” by imagining away homophobia—showing queer characters building relationships in an environment relatively free of discrimination. Despite their differences, I argue that both methods ultimately reinscribe heteronormativity through the assumption that monogamous coupling is the goal of LGBTQ youth.  相似文献

Gamma ray bursts — which are first detected in energetic gamma rays and which then glow in X-ray, visible and radio wavelengths — are the result of the biggest explosions in the universe. Astronomers wonder what causes these violent events, and some of their ideas are discussed in this article.  相似文献

中小学"数学情境与提出问题"教学的实验研究   总被引:1,自引:0,他引:1  
This research tends to make the experimental study on the mathematics teaching model of “situated creation and problem-based instruction” (SCPBI), namely, the teaching process of “creating situations—posing problems—solving problems—applying mathematics”. It is aimed at changing the situation where students generally lack problem-based learning experience and problem awareness. Result shows that this teaching model plays a vital role in arousing students’ interest in mathematics, improving their ability to pose problems and upgrading their mathematics learning ability as well.   相似文献

This paper investigates regional Australian students’ aspirations and expectations for their future and, more specifically, the manner in which these are formulated around a view to move outward — that is, away from regional, remote and rural communities — and onward — that is, to make something of their lives. Drawing upon interview data, the paper highlights the ways in which rural students from across Australia expressed high-level aspirations, most of which centred on future careers. It explores features of student talk which demonstrates that many of them had thought about their futures in detailed ways and had accumulated knowledge and “street savvy” that would assist them in steering their futures. The paper also examines the ways in which student talk about the changing context of the world of work and the inescapability of further education emerge as a naturalised discourse in justifying their future plans. Finally, the paper explores the implications of such research findings for career advisers and teachers working in regional areas of Australia.  相似文献

Conclusion Developing an easy-to-use, complete, practical, reliable, and cost-effective solution for delivering training and education on the Internet has required considerable research and development. We have found that off-the-shelf technologies offer only partial solutions, at best. Even when the software problems were solved, however, we found that our work was just beginning. An effective solution requires software technology, but expertise in instructional design has been equally important. The learning environments our clients create on the Internet have the potential for both “high tech” and “high touch.” These clients are finding ways to reach beyond the physical limitations of the classroom, but—perhaps more significantly—they are using the system to reach beyond the limiting assumptions of the classroom as well. As they—and we—do so, we will begin to understand the ways in which the Net really is a new medium.  相似文献

A common criticism of accountability schemes that are based on comparisons is that they fail to address legitimate and practical questions about how differentiation among institutions can be measured and promoted, and about how distinctive institutional mandates and roles — some of them determined by government mandate — can be recognised and appropriately funded within single systems of higher education. Responding to these queries and suggestions requires some yardstick by which to express and measure similarities and dis-similarities among institutions. At the same time individual institutions, for a variety of reasons ranging from accountability to the allocation of scarce resources, attempt to compare or ‘benchmark’ themselves against other institutions. Both activities involve measurement, classification, and the selection of peers. Although customarily addressed apart from one another, diversity and peer selection can be conceptually closely linked within single scales of similarity and dis-similarity. Existing paradigms that explain diversity might be too simple for reliable peer selection and comparison, and might fail to account for all expressions of diversity. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

This paper addresses the issue of Vocational Education and Training in Schools — an issue that has recently attracted significant political attention particularly in light of current national skills shortage in Australia. Specifically, it investigates secondary school students’ perceptions of VET in Schools [VETiS]. It also explores the factors influencing their decision-making in relation to VETiS — that is, why one might choose, or choose not, to enrol in a VETiS course of study. In view of the findings presented, the paper argues that VET, and more particularly VETiS, is experiencing an “image problem” — one underscored by the need for curriculum design and delivery reform — and suggests that there is much work still to be done on the VET agenda.  相似文献

This paper investigates the ways in which young women come to view gender as being an influence upon their future lives—their aspirations and expectations for the future. In doing so, it draws upon 327 surveys completed by year 12 female students, typically 17 years of age, in a range of schools across the State of Queensland, Australia. The paper details key features of the young women’s survey responses—the dominant storylines evident in the data—as a means of illustrating how they have come to dismiss gender as an influence. Further, the paper illuminates the power and pervasiveness of neoliberal discourse in ‘New Times’, the ways in which the young women surveyed embrace neoliberalism and its imperative of individualisation and do so in ways that locate gender as irrelevant in their imagining and enacting of their life biographies. Finally, the paper explores the implications of such research findings for these—and other—young women.  相似文献

Zusammenfassung Lange haben alltagsweltliche überzeugungen und sozialwissenschaftliche Theorien darin übereingestimmt, die Beziehung zwischen den erwachsenen Generationen in der Familie habe sich im Zuge der gesellschaftlichen Modernisierung und der Entwicklung des Wohlfahrtsstaates zunehmend aufgel?st. Die neuere empirische Forschung weist jedoch nach, dass diese Beziehung überwiegend nach wie vor eng ist und dass darin auch betr?chtliche Versorgungsleistungen erbracht werden. Wir vertiefen diesen Nachweis auf einem bisher vernachl?ssigten Gebiet, n?mlich den materiellen Transfers zwischen den Generationen, und verbinden diese familialen Austauschprozesse mit dem wohlfahrtsstaatlichen „Generationenvertrag“. Es zeigt sich, dass die familialen Transferleistungen — sowohl zu Lebzeiten als auch über Erbschaften — erheblich sind und dass auch die Transfers zu Lebzeiten haupts?chlich von den ?lteren zu den jüngeren Generationen gehen. Die Familie als Solidarsystem wird also durch den Wohlfahrtsstaat nicht geschw?cht, sondern im Gegenteil zu neuen Leistungen bef?higt.
Summary Giving and Getting: The elderly between the generations Everyday popular convictions and social science theories have long agreed that the link between adult generations in the family has disintegrated due to societal modernization and the development of the welfare state. Recent empirical research has, however, shown that the ties between generations are in most cases still strong and that mutual support of considerable value is very common. In this paper we add further evidence by focusing on an area which has largely been neglected so far — material transfers between generations — and relate this exchange within the family to the “generational contract” of the welfare state. We show that private intergenerational transfers — both inter vivos and through inheritance — are substantial and that they usually flow downwards, from the older to the younger generations. We conclude that the family as a system of solidarity is not weakened but to the contrary reinforced by the welfare state.

This article is the second part of our review of the important role that symmetry plays in atomic and subatomic physics. We will concentrate on the discrete symmetries — parity, charge conjugation, and time reversal — that have played a significant part in the development of the ‘standard model’ of particle physics during the latter part of the 20th century. The importance of experimental tests of these symmetries, in both atomic and particle physics, and their sensitivity to new phenomena is also discussed. To conclude, we describe how ‘symmetry breaking’ in the standard model leads to the generation of mass via the Higgs mechanism and how the search for evidence of this symmetry violation is one of the principal goals of the Large Hadron Collider, which began operating at CERN, Switzerland in 2009.  相似文献

In a European project—CoReflect—researchers in seven countries are developing, implementing and evaluating teaching sequences using a web-based platform (STOCHASMOS). The interactive web-based inquiry materials support collaborative and reflective work. The learning environments will be iteratively tested and refined, during different phases of the project. All learning environments are focusing “socio-scientific issues”. In this article we report from the pilot implementation of the Swedish learning environment which has an Astrobiology context. The socio-scientific driving questions are “Should we look for, and try to contact, extraterrestrial life?”, and “Should we transform Mars into a planet where humans can live in the future?” The students were in their last year of compulsory school (16 years old), and worked together in triads. We report from the groups’ decisions and the support used for their claims. On a group level a majority of the student groups in their final statements express reluctance towards both the search of extraterrestrial life and the terraforming of Mars. The support used by the students are reported and discussed. We also look more closely into the argumentation of one of the student groups. The results presented in this article, differ from earlier studies on students’ argumentation and decision making on socio-scientific issues (Aikenhead in Science education for everyday life. Evidence-based practice. Teachers College Press, New York, (2006) for an overview), in that they suggest that students do use science related arguments—both from “core” and “frontier” science—in their argumentation and decision making.  相似文献

Summary The paper focuses upon curriculum planning in the scientific disciplines at university level, although it is claimed the argument may be of wider applicability. Drawing upon the writings of philosophers of education from several decades ago (notably Schwab and Scheffler) whose work is too often overlooked in contemporary debates about the curriculum, and using illustrative examples from the author’s own experience, it is argued that too often the focus of science curriculum planning is the “rhetoric of conclusions” or the “substantive structure” — the current state of knowledge at the forefront of the respective disciplines — to the neglect of what Schwab called the “syntactical structure” of the sciences (which roughly approximates their epistemology). This aspect of these disciplines is essential for the general student trying to become familiar with the nature of science as a broad field of knowledge, for prospective teachers, and — contra Scheffler’s view — for students who aim at careers as researchers.
Zusammenfassung Der Beitrag der Epistemologie zur Curriuculumkonstruktion in den Naturwissenschaften Der Aufsatz fokussiert auf die Curriculumplanung für den naturwissenschaftlichen Unterricht in der universit?ren Lehrerausbildung, wenngleich behauptet wird, dass dieses Argument weitreichendere Anwendbarkeit besitzt. Der Text knüpft an erziehungswissenschaftlichen Schriften (insbesondere von Schwab und Scheffler) an, deren Ver?ffentlichung zwar einige Dekaden zurückliegt, deren Beitrag in den aktuellen Debatten aber oft übersehen wird. Darüber hinaus werden einige illustrative Beispiele aus dem Erfahrungsschatz des Autors genutzt, um zu zeigen, dass der Fokus der Curriculumplanung für die Naturwissenschaften — dem augenblicklichen Wissensstand der zu berücksichtigenden Disziplinen zufolge — zu oft in einer „Rhetorik der Schlussfolgerung“ oder „substantivischen Struktur“ besteht, was dazu führt, dass das, was Schwab die „syntaktische Struktur“ der Naturwissenschaften nennt (und ihrer Epistemologie ziemlich nahe kommt), vernachl?ssigt wird. Dieser Aspekt jener Disziplinen ist besonders wichtig für Studierende, die allgemeinbildend vertraut werden m?chten mit den Naturwissenschaften, für angehende Lehrer und — entgegen Schefflers Ansicht — für Studenten, die eine Karriere als Forscher anstreben.


“When walking in quicksand country, carry a stout pole — it will help you get out should you need to. As soon as you start to sink, lay the pole on the surface of the quicksand. Flop onto your back on top of the pole. Work the pole to a new position: under your hips and at right angles to your spine. Take the shortest route to firmer ground, moving slowly.” Piven/Borgenicht 1999, p. 18
