Equality and excellence. Hegemonic discourses of economisation within the German education system     

Tobias Peter  Ulrich Bröckling 《International Studies in Sociology of Education》2017,26(3):231-247

Looking to conflicting constitutions of education systems through the terms equality and excellence, this paper examines the discursive formation of two political rationalities in the contemporary German education system. While early childhood and primary education discourses are dominated by a terminology of equality, tertiary education institutions such as universities are described using a terminology of excellence that has become a reference point for political interventions and institutional reform processes. Drawing from hegemony theory, governmentality studies and systems theory, this paper analyses the rules of justification referred to by such hegemonic discourses. It presents a policy discourse analysis of strategic, conceptional and institutional texts produced between 2003 and 2010. Through this analysis, the paper suggests that ‘mobilising’ and ‘optimising’ represent the common principles of equality and excellence as economic rationalities.  相似文献   

Unsteady flow phenomena in human undulatory swimming: a numerical approach     

Steffen Pacholak  Stefan Hochstein  Alexander Rudert  Christoph Brücker 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(2):176-194

The undulatory underwater sequence is one of the most important phases in competitive swimming. An understanding of the recurrent vortex dynamics around the human body and their generation could therefore be used to improve swimming techniques. In order to produce a dynamic model, we applied human joint kinematics to three-dimensional (3D) body scans of a female swimmer. The flow around this dynamic model was then calculated using computational fluid dynamics with the aid of moving 3D meshes. Evaluation of the numerical results delivered by the various motion cycles identified characteristic vortex structures for each of the cycles, which exhibited increasing intensity and drag influence. At maximum thrust, drag forces appear to be 12 times higher than those of a passive gliding swimmer. As far as we know, this is the first disclosure of vortex rings merging into vortex tubes in the wake after vortex recapturing. All unsteady structures were visualized using a modified Q-criterion also incorporated into our methods. At the very least, our approach is likely to be suited to further studies examining swimmers engaging in undulatory swimming during training or competition.  相似文献   

Mobilisieren und Optimieren     

Ulrich Bröckling  Tobias Peter 《Zeitschrift für Erziehungswissenschaft》2014,17(3):129-147

Looking at the conflictual constitution of educational systems by equality and excellence, this paper examines the discursive formation of two political rationalities in the contemporary German educational system that are directly opposed. While early childhood and primary education discourses are dominated by a terminology of equity, tertiary education institutions such as universities are described with a terminology of excellence that has become a reference point for political interventions and institutional reform processes.Taking up the theoretical position of hegemony-theory, governmentality studies and system theory, the paper analyzes the rules of justification these hegemonic discourses refer to by employing a discourse analysis of strategic, conceptional, and institutional texts of the German education policy discourse between 2003 and 2010. The paper puts forth the thesis that mobilizing and optimizing represent the common principles of equality and excellence as rationalities of the maximal mobilization of educational ressources.  相似文献   

Characterizing the mechanical parameters of forward and backward falls as experienced in snowboarding     

Schmitt KU  Wider D  Michel FI  Brügger O  Gerber H  Denoth J 《Sports biomechanics / International Society of Biomechanics in Sports》2012,11(1):57-72

Wrist injuries are frequently observed after falls in snowboarding. In this study, laboratory experiments mimicking forward and backward falls were analysed. In six different falling scenarios, participants self-initiated falls from a static initial position. Eighteen volunteers conducted a total of 741 trials. Measurements were taken for basic parameters describing the kinematics as well as the biomechanical loading during impact, such as impact force, impact acceleration, and velocity. The effective mass affecting the wrist in a fall also was determined. The elbow angle at impact showed a more extended arm in backward falls compared to forward falls, whereas the wrist angle at impact remained similar in forward and backward falls. The study results suggest a new performance standard for wrist guards, indicating the following parameters to characterize an impact: an effective mass acting on one wrist of 3-5 kg, an impact angle of 75 degrees of the forearm relative to the ground, and an impact velocity of 3 m/s.  相似文献   

CO₂-Einsparpotenziale des Energietr?gers Erdgas     

Michael Br?uninger  Sebastian Schr?er  Sven Schulze und Henning V?pel 《Zeitschrift für Erziehungswissenschaft》2008,32(1):37-45

Zusammenfassung Angesichts der staatlichen Klimaschutzziele stellt sich die Frage, wie diese mit m?glichst geringer Beeintr?chtigung einer sicheren Versorgung zu günstigen Preisen erreichbar sind. Erdgas, das im Vergleich zu anderen fossilen Energietr?gern deutlich kohlenstoff?rmer ist und darüber hinaus bei der Verbrennung auch keine weiteren Schadstoffe emittiert, kann hier einen Beitrag leisten. Gegenw?rtig hat Erdgas für die Versorgung mit W?rme sowie bei der Erzeugung von Strom eine erhebliche Bedeutung, die zukünftig weiter wachsen wird. Anhand verschiedener Szenarien werden Prognosen zur weiteren Entwicklung von Erdgas und die Auswirkungen auf die CO₂-Emissionen angestellt. Es zeigt sich, dass der Anteil von Erdgas im Bereich der W?rmeversorgung von 46 % auf 56 % steigen wird. Durch ?nderung des Energiemix und Effizienzsteigerungen kann der CO₂-Aussto? für Raumw?rme daher bis 2020 um 8,3 % gesenkt werden. Für die Stromerzeugung werden alternative Szenarien berechnet. Beim derzeitigen Energiemix k?me es zu einer j?hrlichen Steigerung des CO₂-Aussto?es um 0,8 %. Würde Kohle komplett durch Gas ersetzt, k?nnte der CO₂-Aussto? j?hrlich um 1,9 % gesenkt werden.

Given the governmental climate targets, the question arises how these targets can be achieved without affecting a secure and cheap energy supply. As natural gas causes less carbon emissions than any other fossil fuel it might be able to make a contribution in this regard. Currently, in the generation of heat and power natural gas plays a significant role, which will further increase in the future. Using several scenarios, we predict the development of the importance of natural gas and the consequences for carbon emissions. The calculations show that the share of natural gas for the supply of heat will increase from 46 % to 56 %. Efficiency increases together with changes in the structure of power generation can reduce heating-related carbon emissions by 8.3 % until 2020. For power generation, we calculate alternative scenarios. If the current structure of power generation is held constant, carbon emissions will increase by 0.8 % p.a. If instead natural gas completely replaces coal and lignite, the carbon emissions will be reduced by 1.9 % per year.

Effects of memory load on word recognition: Are there dual-routers in Norway?     

Lervåg  Arne  Bråten  Ivar 《Reading and writing》2002,15(3-4):233-259

The release-from-competition (RFC) effect, inwhich a difficult concurrent memory task speedspronunciation of low-frequency irregular wordsbut slows pronunciation of other word types,has been interpreted as strong support for thedual-route approach to word recognition. However, attempts to replicate this effect havenot produced consistent results. Besides,attempts at replication have mostly beenlimited to skilled readers of English. Thepresent research attempted to replicate the RFCeffect with mature normal readers of Norwegianand thus tested the generalizability ofdual-route models to a considerably moreshallow orthography than English. There was noevidence that the RFC effect reliably occurredamong Norwegian readers in this study, not evenamong certain selected readers who were seen ascandidates for possessing a dual-routearchitecture and suffering within thatarchitecture the kind of competition in naminglow-frequency irregular words that RFC issupposed to eliminate. Thus, it was notpossible to extend the applicability of adual-route approach to word recognition to therelatively shallow Norwegian orthography, andthe question of the architectural organizationof Norwegian readers was essentially leftunanswered by our data.  相似文献   

The use of augmented reality to foster conceptual knowledge acquisition in STEM laboratory courses—Theoretical background and empirical results     

Kristin Altmeyer  Sebastian Kapp  Michael Thees  Sarah Malone  Jochen Kuhn  Roland Brünken 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(3):611-628

Learning with hands-on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to the correspondent components in the experimentation environment, thereby ensuring a basic design principle for multimedia instruction: the spatial contiguity principle. The latter is assumed to reduce learners' extraneous cognitive load and foster generative processing, which supports conceptual knowledge acquisition. For the present study, a tablet-based AR application has been developed to support learning from hands-on experiments in physics education. Real-time measurement data were displayed directly above the components of electric circuits, which were constructed by the learners during lab work. In a two group pretest–posttest design, we compared university students' (N = 50) perceived cognitive load and conceptual knowledge gain for both the AR-supported and a matching non-AR learning environment. Whereas participants in both conditions gave comparable ratings for cognitive load, learning gains in conceptual knowledge were only detectable for the AR-supported lab work.  相似文献   

The learning and study strategies of Norwegian first-year college students     

Ivar Braten  Bodil S. Olaussen 《Learning and individual differences》1998,10(4):309-327

In this study, we examined the learning and study strategies of 173 Norwegian first-year college students and compared the resulting profiles to those of the American students who established the norms for the selected strategy measure (i.e., Learning and Study Strategies Inventory [LASSI]). In addition, we compared the strategy profiles of students with different levels of perceived ability, gender, and age. It was found that the profiles of the Norwegian students were remarkably similar to the profiles of the American norming sample, with only the Motivation subscale of the LASSI showing a large difference between the two samples. Moreover, students with high perceived ability reported using more strategies than students with low perceived ability, and female students, on the whole, reported using more strategies than males. Finally, the age differences in reported strategy use were rather small among the Norwegian students. The results of this study are discussed in both cross-cultural and practical perspectives.  相似文献
