The thermal chiral anomaly in the Schwinger model
Creators: name: Das, Ashok
name: Frenkel, J.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In the Schwinger model at finite temperature, we derive a closed form result for the chiral anomaly which arises from the long distance behavior of the electric field \cite{frenkel}. We discuss the general properties associated with this thermal anomaly as well as its relation with the "index" of the Dirac operator. We further show that the thermal anomaly, like the zero temperature anomaly which arises from the ultraviolet behavior of the theory, does not receive any contribution from higher loops. Finally, we determine the complete effective action as well as the anomaly functional on both the thermal branches in the closed time path formalism.

“Patriotism” as a Goal of School Education in China and Japan

Year: 2011
Subjects: Civic education; socialism; nationalism; transformation of patriotism; Chinese-Japanese relations

description: In the eyes of much of the Japanese public, “patriotism education” in China is synonymous with anti-Japanese education, and a source of friction. Much of that friction, however, can be attributed to the differing roles and functions of “patriotism” in the two countries as well as the variant connotations of the very word for “patriotism”. In China, the communist party avails itself of the strong levels of patriotism among the people in order to advance modernization of the country. Patriotism education is not designed to serve as anti-Japanese education. In Japan, however, given the country’s past role as an aggressor nation, that word has had consistently negative connotations. Debates over its own patriotism have continued and there are accordingly inexorable apprehensions over patriotism education in China. To address the recurrent frictions between these two countries, both must overcome their ignorance about the differences that Chinese and Japanese societies manifest

Unter der „patriotischen Erziehung“ in China versteht man in Japan generell eine anti-japanische Erziehung. Der bilaterale Streit um diese chinesische Bildungspolitik liegt aber in der unterschiedlichen Stellung begründet, welche der Begriff „Patriotismus“ in der Gesellschaft der beiden Nationen einnimmt. In der Annahme, dass es einen ausgeprägten Patriotismus im Volk gibt, hat sich die Kommunistische Partei die patriotische Erziehung zunutze gemacht, um den Staat zu modernisieren. Die anti-japanische Erziehung war dabei zumindest nicht beabsichtigt. Andererseits bekam der Patriotismus in Japan, durch die eigene Erfahrung des Invasionskriegs, eine negative Konnotation. Dort ist die Debatte um den heimischen Patriotismus noch nicht abgeschlossen, und auch die chinesische Bildungspolitik wird sehr kritisch angesehen. Um die wiederholten Konflikte zwischen den beiden Ländern zu lösen, muss man bei der Überwindung des gegenseitigen Unwissens und der Gleichgültigkeit bezüglich der Unterschiede ihrer Gesellschaften anfangen.

History Education and Civic Education: The Bulgarian Case
Creators: name: Hranova, Albena

Year: 2011
Subjects: Textbook research; history textbooks; civic education; Bulgaria.

description: This text looks at the developments in the relationship between history education and civic education in the Bulgarian educational tradition in the 1878-1944 period and tends to finally refer to the present state of affairs. It examines the political contexts of the methods and writing of textbooks which have ensured the political longevity of the conservative nationalist model in the worldview of both school subjects. The observations are based upon more than eighty textbooks on history and civic education published since 1878 (of which only those that are typical and representative of the dominant trends in the Bulgarian educational tradition are cited here) as well as upon some works in didactics. The main features in the texture of the conservative model are identified on the basis of a discourse analysis of history and civic education textbooks, and they concern the disciplinary, spatio-temporal, and conceptual homologies found in them.

description: Ferromagnetic-insulator (FI) based Josephson junctions are promising candidates for a coherent superconducting quantum bit as well as a classical superconducting logic circuit. Recently the appearance of an intriguing atomic-scale 0-pi transition has been theoretically predicted. In order to uncover the mechanism of this phenomena, we numerically calculate the spectrum of Andreev bound states in a FI barrier by diagonalizing the Bogoliubov-de Gennes equation. We show that Andreev spectrum drastically depends on the parity of the FI-layer number L and accordingly the pi (0) state is always more stable than the 0 (pi) state if L is odd (even).

Subjects: Turkish Social Studies Education; Teacher Education; Curriculum Reform in Turkey; Turkish Social Studies Textbooks; Constructivism

description: This article aims to portray and discuss the current status of social studies education in Turkey in terms of both K-8 and pre-service teacher education levels. The article starts with a brief history about the Turkish social studies education followed by the recent curriculum reform movements in Turkey. Then, the curriculum changes and the reform movements in pre-service social studies teacher education are discussed by analyzing the related literature. The discussion indicates the dominancy of standardized test in the Turkish educational system, teachers’ lack of knowledge and experience, and the limited resources to apply the new curriculum are the major issues for K-8 social studies education. In addition, the quality of social studies teacher education and teacher educators also is another issue that must be addressed. In conclusion, it is agreed by many scholars and educators the reform movements were rushed and the new reforms were applied without perfect planning

The Josephson relation for the superfluid density and the connection to the Goldstone theorem in dilute Bose atomic gasses

Year: 2011

description: We derive the Josephson relation for a dilute Bose gas in the framework of an auxiliary-field resummation of the theory in terms of the normal- and anomalous-density condensates. The mean-field phase diagram of this theory features two critical temperatures, T_c and $T^*, associated with the presence in the system of the Bose-Einstein condensate (BEC) and superfluid state, respectively. In this context, the Josephson relation shows that the superfluid density is related to a second order parameter, the square of the anomalous-density condensate. This is in contrast with the corresponding result in the Bose gas theory without an anomalous condensate, which predicts that the superfluid density is proportional to the BEC condensate density. Our findings are consistent with the prediction that in the temperature range between T_c and T^* a fraction of the system is in the superfluid state in the absence of the BEC condensate. This situation is similar to the case of dilute Fermi gases, where the superfluid density is proportional to the square of the gap parameter. The Josephson relation relies on the existence of zero energy and momentum excitations showing the intimate relationship between superfluidity and the Goldstone theorem.

Core Concept “Political Compass”. How Kitschelt’s Model of Liberal, Socialist, Libertarian and Conservative Orientations Can Fill the Ideology Gap in Civic Education
Creators: name: Petrik, Andreas
Publisher: name: sowi-online e.V., Bielefeld
Year: 2010
Subjects: Political cleavages; ideologies; critical thinking skills; political judgment abilities; political compass; “Found-a-Village-Project”

description: International value surveys and misconception studies reveal the crucial role of individual value orientations for political judgment abilities. But in Civic Education, political opinions are generally merely asked for or remain superficial, non-committal statements that don’t get analyzed to foster identity development, perspective-taking and tolerance. Thus, this article discusses Kitschelt’s coordinate system of political preferences as an outstanding solution to fill the ideology gap in Civic Education and therefore to enhance political literacy. At first, I will explain and outline the landscape of the four political ideologies: market-liberalism, conservatism, democratic socialism and left-libertarianism. In addition, I will trace left-libertarianism to its merely known anarchist roots. After that, I will explain how our basic political values are shaped by economic and cultural developments and how they combine to become political ideologies, social milieus and party families. As a third point, I will outline possible applications of Kitschelt’s model for the subject of Civic Education. For that, I propose a map of fundamental controversial issues to help students to discover their own political position. Finally, I will introduce the “Found-a-Village-Project” as highly interactive and controversial scenario to foster political identity formation.

description: Under certain hypotheses on the Banach space $X$, we show that the set of $N$-homogeneous polynomials from $X$ to any dual space, whose Aron-Berner extensions are norm attaining, is dense in the space of all continuous $N$-homogeneous polynomials. To this end we prove an integral formula for the duality between tensor products and polynomials. We also exhibit examples of Lorentz sequence spaces for which there is no polynomial Bishop-Phelps theorem, but our results apply. Finally we address quantitative versions, in the sense of Bollobás, of these results.
Political Competences and Political Participation: On The Role of “Objective” Political Knowledge, Political Reasoning, and Subjective Political Competence in Early Adulthood
Creators: name: Reichert, Frank
Publisher: name: sowi-online e.V., Bielefeld
Year: 2010
Subjects: Civic education; political competence; political education; political efficacy; political knowledge; political participation; political reasoning

description: This article deals with the relation of objective political competences and the subjective assessment of one’s own political competence. The theoretical frame states that at least in early adulthood, only the subjective competence but not political knowledge is an autonomous and important determinant for (socio-)political participation, mediating the influence of objective political competences (or political knowledge, respectively). To test the role of subjective political competence and the (remaining) effect of political knowledge in early adulthood, empirical evidence using a sample of university students is presented. Cross-sectional analyses show that political knowledge has at least, if anything, an impact on voting, while fully mediated by subjective political competence relating non-electoral legal political activities. In contrast, the more profound competence of political reasoning has clear and stable positive effects on the intention to engage in non-electoral legal political actions – here subjective competence seems to be less important. Eventually, after a short excursus on school participation the findings are summarised and discussed by relating them back to framework and hypothesis. A concluding section proposes two opposing developmental-psychological considerations about the findings, raising further questions and giving an outlook into future research.

The Generalized A* Architecture

Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)

description: We consider the problem of computing a lightest derivation of a global structure using a set of weighted rules. A large variety of inference problems in AI can be formulated in this framework. We generalize A* search and heuristics derived from abstractions to a broad class of lightest derivation problems. We also describe a new algorithm that searches for lightest derivations using a hierarchy of abstractions. Our generalization of A* gives a new algorithm for searching AND/OR graphs in a bottom-up fashion. We discuss how the algorithms described here provide a general architecture for addressing the pipeline problem --- the problem of passing information back and forth between various stages of processing in a perceptual system. We consider examples in computer vision and natural language processing. We apply the hierarchical search algorithm to the problem of estimating the boundaries of convex objects in grayscale images and compare it to other search methods. A second set of experiments demonstrate the use of a new compositional model for finding salient curves in images.
Polaron Transport in Organic Crystals: Temperature Tuning of Disorder Effects

Year: 2011
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We explore polaronic quantum transport in three-dimensional models of disordered organic crystals with strong coupling between electronic and vibrational degrees of freedom. By studying the polaron dynamics in a static disorder environment, temperature dependent mobilities are extracted and found to exhibit different fingerprints depending on the strength of the disorder potential. At low temperatures and for strong enough disorder, coherence effects induce weak localization of polarons. These effects are reduced with increasing temperature (thermal disorder) resulting in mobility increase. However at a transition temperature, phonon-assisted contributions driven by polaron-phonon scattering prevail, provoking a downturn of the mobility. The results provide an alternative scenario to discuss controversial experimental features in molecular crystals.

They follow from the gauge invariance of the effective action, and allow to derive new representations of amplitudes containing physical particles as well as reggeized gluons. We explicitly demonstrate their validity for the BFKL kernel, and we present a new derivation of the kernel.

Implications of the Daya Bay observation of θ_{13} on the leptonic flavor mixing structure and CP violation

description: The Daya Bay Collaboration has recently reported its first \barν_e \to \barν_e oscillation result which points to θ_{13} \simeq 8.8^\circ \pm 0.8^\circ (best-fit \pm 1σrange) or θ_{13} \neq 0^\circ at the 5.2σlevel. The fact that this smallest neutrino mixing angle is not strongly suppressed motivates us to look into the underlying structure of lepton flavor mixing and CP violation. Two phenomenological strategies are outlined: (1) the lepton flavor mixing matrix U consists of a constant leading term U_0 and a small perturbation term ΔU; and (2) the mixing angles of U are associated with the lepton mass ratios. Some typical patterns of U_0 are reexamined by constraining their respective perturbations with current experimental data. We illustrate a few possible ways to minimally correct U_0 in order to fit the observed values of three mixing angles. We point out that the structure of U may exhibit an approximate μ-τpermutation symmetry in modulus, and reiterate the geometrical description of CP violation in terms of the leptonic unitarity triangles. The salient features of nine distinct parametrizations of U are summarized, and its Wolfenstein-like expansion is presented by taking U_0 to be the democratic mixing pattern.

description: Aims: Previous estimates of planet occurrence rates in the CARMENES survey indicated increased numbers of planets on short orbits for M dwarfs with masses below 0.34\,M$_\odot$. Here we focused on the lowest-mass stars in the survey, comprising 15 inactive targets with masses under 0.16\,M$_\odot$.
 Methods: To correct for detection biases, we determined detection sensitivity maps for individual targets and the entire sample. Using Monte Carlo simulations, we estimated planet occurrence rates for orbital periods of 1\,d to 100\,d and minimum masses from 0.5\,M$_\oplus$ to 10\,M$_\oplus$.
 Results: The radial velocity (RV) data from CARMENES reveal four new planets around three stars in our sample, namely G~268--110\,b, G~261--6\,b, and G~192--15\,b and c. All three b planets have minimum masses of 1.03--1.52\,M$_\oplus$ and orbital periods of 1.43--5.45\,d, while G~192--15\,c is a 14.3\,M$_\oplus$ planet on a wide, eccentric orbit with $P \approx 1218$\,d and $e \approx 0.68$.
 Our occurrence rates suggest considerable dependencies with respect to stellar masses. For planets below 3\,M$_\oplus$ we found rates consistent with one planet per star across all investigated periods, but the rates decrease almost by an order of magnitude for larger planet masses up to 10\,M$_\oplus$. Compared to previous studies,
 low-mass stars tend to harbor more planets with $P <10$\,d. We also demonstrate that synthetic planet populations based on the standard core accretion scenario predict slightly more massive planets on wider orbits than observed.
 Conclusions: Our findings confirm that planet occurrence rates vary with stellar masses even among M dwarfs, as we found more planets with lower masses and on shorter orbits in our subsample of very low-mass stars compared to more massive M dwarfs. Therefore, we emphasize the need for additional differentiation in future studies.

description: We investigate how the properties of escaping stars are related to the initial conditions of their birth clusters. We find that the number of escaping stars, their spatial distribution, and their kinematics show a dependence on the initial conditions of the host cluster (substructure and virial ratio). Thus the properties of escaping stars can be used to inform us of the initial conditions of star formation, and also provide a window into the dynamical history of star clusters. The ESA Gaia mission will make observations of the positions and proper motions of these escaping stars at the required accuracy to allow us to investigate the dynamical evolution of local star clusters and provide an important insight into the initial conditions of star formation.

description: Obwohl sich der Diskurs über den Umgang mit Heterogenität und Diversität in den letzten Jahren intensiviert hat, ist das Thema wirtschaftsdidaktisch „unterbelichtet“. Im Beitrag werden – ohne einen Anspruch auf Vollständigkeit – einige grundsätzliche Überlegungen über den Umgang mit Heterogenität und Diversität angesprochen. Hervorgehoben wird, dass in der Diskussion die je spezifische und komplexe Bedürfnislage des Einzelnen ins Zentrum gerückt wird, also subjektbezogene Differenzkategorien im Mittelpunkt stehen. Welche Herausforderungen sich angesichts objektbezogener Differenzkategorien ergeben, wird nur gelegentlich angesprochen. Angesicht der heterogenen Weltbilder, Paradigma und Bezugsdisziplinen für und in einer sozialwissenschaftlichen Bildungslandschaft mit ihrer Vielzahl an fachdidaktischen Konzepten und den damit verbunden didaktischen Handlungsfeldern (Curricula, Bildungsstandards, Lehr-Lern-Methoden, Materialien, Lehr-Lern-Umgebungen etc.) stellen sich ein ganzes Bündel von Fragen, die in diesem Beitrag aufgelistet und partiell in diesem Heft erörtert werden.

description: In this article, we generalize the Wasserstein distance to measures with different masses. We study the properties of such distance. In particular, we show that it metrizes weak convergence for tight sequences. We use this generalized Wasserstein distance to study a transport equation with source, in which both the vector field and the source depend on the measure itself. We prove existence and uniqueness of the solution to the Cauchy problem when the vector field and the source are Lipschitzian with respect to the generalized Wasserstein distance.

This paper shows that the actual temperature, as measured by a thermometer is still zero (or in the thermal state of the bath, the temperature of the bath). The decoherence temperature is due to "false-decoherence", with the heat bath state being dragged along with the oscillator.

description: Heterogenität der Schülerschaft, wie sie sich im Zuge eines zunehmenden binnengesellschaftlichen Pluralismus von Kulturen ergibt, stellt das professionelle Handeln von Lehrern vor neue Herausforderungen. Der mangelnde Bildungserfolg, der mit verschiedenen Dimensionen von Heterogenität einhergeht, ist ein Indikator für bestehende Probleme im Umgang mit Heterogenität. Trotz des zunehmenden Interesses am Thema fehlt es aber an einer breiten und systematisch gewonnenen Wissensbasis zur professionellen Auseinandersetzung mit Heterogenität. Unklar ist, wie pädagogische Professionalisierung besser an neue, mit wachsender Heterogenität einhergehende Anforderungen des Schulalltags angepasst werden kann. Hierzu bedarf es eines umfassenden Forschungsprogramms. In dem Beitrag wird der Rahmen für ein derartiges Programm abgesteckt, indem der Blick 1) auf vorliegende Erkenntnisse zum Zusammenhang zwischen Heterogenität und Bildungserfolg, 2) auf unterschiedliche Konzepte zum Umgang mit Heterogenität und 3) auf die Vermittlung geforderter Kompetenzen in der Lehrerbildung gerichtet wird. Die hierbei konstatierten Defizite führen zur systematischen Verortung von anzugehenden Forschungsbereichen

 Student diversity, resulting from an increasing pluralism of cultures within society, is a major challenge for teachers’ professional action. The fact that problems in school achievement are associated with different dimensions of diversity hints to existing problems in dealing with diversity. Although student diversity is increasingly focused in educational discourses, a broad and systematically gained knowledge base is still lacking. It remains unclear, how the professional training and development of teachers can be adjusted to the demands of increasing diversity within schools. A comprehensive research program is needed to overcome this deficit. The paper delineates the frame for such a program by looking at 1) existing research on the relation between aspects of diversity and student achievement, 2) different concepts for dealing with diversity and 3) the acquisition of needed competencies in teachers’ training. The identified deficits lead to a systematic positioning of research arenas.

Near-Earth Binaries and Triples: Origin and Evolution of Spin-Orbital Properties

description: In the near-Earth asteroid population, binary and triple systems have been discovered with mutual orbits that have significant eccentricities as well as large semi-major axes. All known systems with eccentric orbits and all widely-separated primary-satellite pairs have rapidly rotating satellites. Here we study processes that can elucidate the origin of these spin-orbital properties. Binary formation models based on rotational fissioning can reproduce asynchronous satellites on orbits with high eccentricities and a wide range of separations, but do not match observed properties. We explore whether any evolutionary mechanisms can link the spin and orbital parameters expected from post-fission dynamics to those observed today. We investigate four processes: tidal torques, radiative perturbations (BYORP), close planetary encounters, and Kozai oscillations. We find that a combination of post-fission dynamics and tidal evolution can explain nearly all the spin-orbit properties in a sample of nine well-characterized near-Earth binaries and triples. The other mechanisms may act but are not required to explain the observed data. Lastly, we describe evolutionary pathways between observed spin-orbital states including synchronous and circular, asynchronous and circular, and asynchronous and eccentric configurations.

Habitus in the Classroom: the Relevance of Student Heterogeneity and Departmental Culture for Learner-Oriented Didactics in Teaching Sociology (Didaktische Strategien zum Umgang mit habitueller Vielfalt und spezifischer Fachkultur in Soziologie)

description: The relevance of habitus, social origin and the mechanisms of exclusion as applied by the university system has often been discussed in current research. It has been stated that opportunities of students are impaired by field-of-study orientations and drop-out rates. In contrast to this, the aspect how university teachers can practically deal with this knowledge is less elaborated. In view of this, this article presents methods of how learner-oriented approaches, with special reference to the heterogeneity of student milieus, can be implemented in teaching sociology. On the basis of reviewing theoretical approaches and recent empirical data, this article points out a) what data are relevant for the operationalisation of learner oriented didactics, b) what concrete problems might occur in the teacher-student-relationship and c) what techniques are to be applied by sociology teachers in handling classroom problems. The results demonstrate that teaching methods which adequately respond to heterogeneity within the culture of sociology departments are imperative and available. Still, to establish equal opportunities, a more practical turn in a hitherto predominantly theoretical discussion is clearly needed

Chancenungleichheit durch Passungsdifferenzen unterschiedlicher sozialer Milieus zum Hochschulsystem ist schon häufig theoretisch diskutiert worden. Zudem geben empirische Untersuchungen detaillierte Einblicke in studentische Milieus und Fachkulturen. Bei der Literaturrezeption entsteht der Eindruck, eine didaktische Reaktion auf das Problem der hochschulinternen Exklusionsmechanismen könnte nicht dringend genug sein. Die Konzeption entsprechender didaktischen Ansätze wird aber wenig thematisiert. Dieser Artikel hat den Anspruch, konkrete Umsetzungsmöglichkeiten von lernerzentrierten didaktischen Ansätzen im Fach Soziologie aufzuzeigen. In einem Fach, das grundsätzlich sensibel für Ungleichheiten ist, fehlen trotzdem heterogenitätsorientierte Gestaltungskonzepte. Der vorliegende Aufsatz will diese Lücke schließen und beantworten a) welche der Informationen über studentische Milieus relevant für die Konzeption einer lernerzentrierten Didaktik ist, b) welche konkreten Passungsprobleme sich in Lehr-Lern-Settings ergeben könnten und c) mit welchen Methoden diesen Problemen begegnet werden kann. Die Ergebnisse zeigen nicht nur, dass eine heterogenitätssensible, lernerbezogene Didaktik bereits jetzt methodisch möglich ist.

description: This Letter presents measurements of l nu gamma and l^+ l^- gamma (l=e, mu) production in 1.02 fb^-1 of pp collision data recorded at sqrt(s) = 7 TeV with the ATLAS detector at the LHC during 2011. Events dominated by W gamma and Z gamma production with leptonic decays of the W and Z bosons are selected, and their production cross sections and kinematic properties are measured in several ranges of the photon transverse energy. The results are compared to Standard Model predictions and are used to determine limits on anomalous W-W-gamma and Z-Z-gamma/Z-gamma-gamma couplings.

On the Origin of the Salpeter Slope for the Initial Mass Function
Creators: name: Oey, M. S.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We suggest that the intrinsic, stellar initial mass function (IMF) follows a power-law slope gamma=2, inherited from hierarchical fragmentation of molecular clouds into clumps and clumps into stars. The well-known, logarithmic Salpeter slope GAMMA=1.35 in clusters is then the aggregate slope for all the star-forming clumps contributing to an individual cluster, and it is steeper than the intrinsic slope within individual clumps because the smallest star-forming clumps contributing to any given cluster are unable to form the highest-mass stars. Our Monte Carlo simulations demonstrate that the Salpeter power-law index is the limiting value obtained for the cluster IMF when the lower-mass limits for allowed stellar masses and star-forming clumps are effectively equal, m_lo = M_lo. This condition indeed is imposed for the high-mass IMF tail by the turn-over at the characteristic value m_c ~ 1 M_sun. IMF slopes of GAMMA ~ 2 are obtained if the stellar and clump upper-mass limits are also equal m_up = M_up ~ 100 M_sun, and so our model explains the observed range of IMF slopes between GAMMA ~ 1 to 2. Flatter slopes of GAMMA = 1 are expected when M_lo > m_up, which is a plausible condition in starbursts, where such slopes are suggested to occur. While this model is a simplistic parameterization of the star-formation process, it seems likely to capture the essential elements that generate the Salpeter tail of the IMF for massive stars. These principles also likely explain the IGIMF effect seen in low-density star-forming environments.

Gendertheoretische Überlegungen im Umgang mit Heterogenität in der Schule? (Considerations from the Perspective of Gender Theory about Dealing with Heterogeneity in School)

description: Im schulpädagogischen Diskurs über Heterogenität werden derzeit die unterschiedlichen Voraussetzungen von Lernenden erörtert. Dies betrifft auch das Geschlecht des Schülers und die subjektiven Geschlechterkonstruktionen der Lehrkräfte. Sie neigen oft dazu, im Unterricht geschlechtsstereotypische Erwartungen an die Schüler zu formulieren. In der Heterogenitätsforschung wird jedoch betont, dass Mädchen und Jungen zwar besondere Fähigkeiten besitzen können, es wird aber gleichzeitig auf die Problematik einer geschlechtlich dichotomen Rollenzuschreibung hingewiesen, die einer Gleichwertigkeit in den Bildungschancen entgegengewirkt. Der Aufsatz behandelt Schwerpunkte der schulpädagogischen Geschlechterforschung. Dabei werden die unterschiedlichen Lebensentwürfe von jungen Frauen und Männern im Bildungsprozess vorgestellt und die Koedukation unter dem kritischen Blick auf die geschlechtliche Segregation des Arbeitsmarktes diskutiert

The school pedagogy’s discourse on heterogeneity currently debates the diverse conditions of learners. This also regards the gender of pupils and the subjective constructions of gender roles by teachers. During lessons, teachers often tend to formulate expectations of gender-stereotypical behaviour to their pupils. Yet, in the research of heterogeneity, it is stressed that girls and boys may indeed possess different skills and abilities but at the same time the problem of a dichotomous role ascription to both genders is pointed out which counteracts equality of educational opportunities. The paper deals with three foci of the school pedagogy’s gender research. The different life courses of young women and men in the process of their education is depicted. Co-education is critically examined with regard to the gender segregation of the employment market.

description: Der vorliegende Beitrag widmet sich der Erfassung heterogenen Verständnisses von ökonomischen Phänomenen bei Schülerinnen und Schülern. Die Autoren gehen davon aus, dass ein besseres Verständnis dieser Heterogenität für die Wirtschaftsdidaktik in Wissenschaft und Praxis von fundamentaler Bedeutung ist. Da mit der Phänomenographie ein geeignetes Erfassungsinstrument zur Verfügung steht, das in der sozialwissenschaftlichen Didaktik des deutschsprachigen Raums bisher nahezu keine Rolle spielt, versprechen sie sich gerade hier neue Impulse. Der Artikel beschreibt und diskutiert ein phänomenographisches Vorgehen für die ökonomische Bildung in Abgrenzung zu anderen Methoden. Er schließt mit Implikationen für die Unterrichtspraxis, da eine Kombination der Phänomenographie mit einer Konzeptvariation die Schülerwahrnehmungen in den Wirtschaftsunterricht integrieren lässt und hilft, Lernfortschritte zu erzielen

This article addresses the issue of identifying students’ heterogeneous understanding of economic phenomena. The authors assume that a better understanding of this heterogeneity is essential for economic education in science and practice. Phenomenography stands by as an adequate tool for identifying heterogeneity. However, so far, it is hardly adapted in German-speaking social science didactics and therefore we hope for new stimuli from its reception. The article describes and discusses the phenomenographic approach in economic education in distinction to other available methods. It closes by showing the implications for lesson practice, because a combination of phenomenography and concept variation will help to integrate students’ perceptions into economic instruction and to achieve progress in learning.
