Towards a research training curriculum: What, Why, How, Who?

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’.     

The contribution of epistemology to curriculum construction in the sciences

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.

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

The importance of being ignorant

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.     

Conceptions for relating the evolution of mathematical concepts to mathematics learning—epistemology, history, and semiotics interacting To the memory of Carl Menger (1902–1985)

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.”     

The second promise ofbrown

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.     

Snippets of physics

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.     

Web-based education: A reality check

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.     

Looking “outward and onward” in the outback: Regional Australian students’ aspirations and expectations for their future as framed by dominant discourses of further education and training

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.     

Blended university teaching using virtual learning environments: conceptions and approaches

This paper reports findings from a phenomenographic investigation into blended university teaching using virtual learning environments (VLEs). Interviews with 25 Computer Science teachers in Greek universities illuminated a spectrum of teachers’ conceptions and approaches from ‘teacher-focused and content-oriented’, through ‘student-focused and content-oriented’, to ‘student-focused and process-oriented’. Using VLEs was described as a means of supporting: A—information transfer; B—application and clarification of concepts; C—exchange and development of ideas, and resource exploration and sharing; D—collaborative knowledge-creation, and development of process awareness and skills. The study suggests that pedagogical beliefs and circumstances underpinning face-to-face teaching are more influential in shaping approaches to blended VLE use than VLE system features. The authors propose that the findings could be used to inform educational enhancement initiatives and that there is a need for further discipline-focused research on blended teaching.     

中小学"数学情境与提出问题"教学的实验研究

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.      

Students’ Socio-Scientific Reasoning in an Astrobiological Context During Work with a Digital Learning Environment

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.     

Young women’s dismissal of the influence of gender upon their future life trajectory as played out in ‘New Times’

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.     

Catalyzing country ownership and aid effectiveness: Role of the Education for All-Fast Track Initiative Catalytic Fund

This article examines the contribution of the Education for All-Fast Track Initiative (EFA-FTI) global partnership in strengthening aid effectiveness in the education sector, and specifically how the implementation modalities of the EFA-FTI Catalytic Fund (CF) have contributed to this strengthening. The empirical findings are based on a review covering the period 2005–2007, when the CF grant was first established. The review includes an assessment of the quality of the education sector plans for 25 countries in the partnership, the implementation modalities of the CF grant in 18 countries, and feedback from countries’ participants. The qualitative assessment of the CF implementation modalities is based on three areas—alignment, harmonization, and managing for results—and uses a good practice checklist based on the Paris Declaration partnership commitments. Progress on the good practice checklist in the education sector is compared to progress at the country level as a whole; the latter is derived from the Aid Effectiveness Profiles prepared by the World Bank. The review of the sample countries finds that in the education sector, alignment was stronger than at the country level, progress toward harmonization was somewhat stronger, and managing for results was the same as at the country level. The article concludes that while the FTI has contributed to improving aid effectiveness, moving forward requires different actions at the two levels—global and country level—on which the partnership operates.     

Lexical decision and oral reading by poor and normal readers

The primary goal of this study was to compare a paper-and-pencil version of the lexical decision task, which can be administered groupwise, with reading aloud a differently ordered list of the same words and pseudowords. Participants were first and second graders (“normal readers”) and students from schools for children with learning difficulties. On the average, the latter “poor readers” scored at the same oral reading level as the normal readers, but were older. The correlation between both tasks appeared to be high and both tasks had comparable correlations with third variables, suggesting that performance is determined by the same processes. Because the lexical decision task showed little evidence for guessing, it may be an — even better — alternative for oral reading. No differences between participant groups were found that point to different reading strategies. Error analysis, however, indicates that the poor readers probably have a specific problem in the oral reading of pseudowords.

Creativity and whole school change: An investigation of English headteacher practices

Schools in England have been required to adopt and adapt an ongoing series of policy initiatives: some however are offered on an ‘opt-in’ basis. This paper examines one such ‘offer,’ that of Creative Partnerships, a programme which provides schools in designated deprived areas the opportunity to work with creative practitioners in order to change both classroom practice and whole schools. We report here on the snapshot phase of a national study, using a corpus of multi-method qualitative data from 40 schools. We suggest that headteachers saw different opportunities in the CP offer but what actually happened in the school related to three interwoven strands: the situatedness of the school, the headteacher’s stance towards change, and the architecture of change management. Our analysis, which highlights the ways in which many of the schools were unable to ‘spread and embed’ the pedagogical changes supported through CP, suggests that the majority of heads could benefit from involvement in explicit discussion about ‘unofficial’—and more democratic—approaches to leading and managing change.     

The biggest explosions in the universe

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.     

Groupwork as a form of assessment: common problems and recommended solutions

This paper reviews some of the literature on the use of groupwork as a form of assessment in tertiary institutions. It outlines the considerable advantages of groupwork but also its systemic associated problems. In discussing the problems, the paper considers issues such as “free riding” and the “sucker effect”, issues associated with ethnic mix in groups, and the social dilemma problem—in which students face conflicting demands between altruism and self-interest. The paper then outlines several models of effective groupwork and makes suggestions for implementing groupwork tasks. The paper also looks at the key assessment tasks which are commonly employed—namely, additive, conjunctive, disjunctive and discretionary tasks—and assesses which are most suited to groupwork. The paper considers the related issues of task complexity, recognition for effort, and strategies for minimising issues concerning group size. The paper also briefly considers strategies for implementing incentives for groupwork members, and outlines the issue of penalties for unproductive group members. The paper concludes by providing recommendations for how to maximise the advantages of groupwork while trying to minimise the disadvantages.     

New Teachers, High-Stakes Diversity, and the Performance-Based Conundrum

This article explores the impact of high-stakes gate-keeping assessments (of both K-12 students and new teachers) on teacher development of equitable teaching practices. Drawing from two studies of field experiences in Washington State—one of teacher interns and one of cooperating teachers—findings include that state level policies in response to NCLB may actually be decreasing teacher attention to closing the achievement gap. Further, the article explores how even progressive performance-based standards—when administered “globalistically”—are generally ineffective. After discussing university complicity in exacerbating the problem, the paper concludes with ways policymakers may shift their attention from creating complicated rubrics to promoting relationships that support pedagogical change.Jason Margolis is an Assistant Professor in Teacher Education and Professional Development Partnerships, Washington State University.     

Symmetry principles and conservation laws in atomic and subatomic physics — 2

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.
