The interplay between individual and collective knowledge: technologies for organisational learning and knowledge building

This article presents a framework model that defines knowledge building as a co-evolution of cognitive and social systems. Our model brings together Nonaka's knowledge-creating theory and Luhmann's systems theory. It is demonstrated how collaborative knowledge building may occur – in an ideal situation – within an organisation, when people interact with each other using shared digital artefacts. For this purpose, three different technologies are introduced as examples: social-tagging systems, pattern-based task-management systems, and wikis. These examples have been chosen to demonstrate that knowledge building can occur with respect to both declarative and procedural knowledge. The differences and similarities between these technologies, as far as their potential for organisational knowledge building is concerned, are discussed in the light of the framework model.     

Long-term effects of acoustic reafference training (ART)

In sport visual feedback is often used to enhance performance, mostly neglecting the auditory modality. However, athletes produce natural sounds when they move (acoustic reafferences) which they perceive and use to control their movements. We examined the short- and long-term effects of a training intervention on a complex movement by using acoustic reafferences. Natural step sounds produced during hurdling were recorded and played back to the participants immediately before each trial, with an increase (fast group), decrease (slow group), or no manipulation (control group) in the tempo. All groups increased their hurdling performance regarding overall running time, with the slow group showing the best performance development. After a 10-week retention, the fast and slow group further increased performance, whereas the control group declined. The repeated experience with acoustic information associated with the rhythmic pattern of hurdling may have helped developing a cognitive representation of that movement, especially regarding long-term effects.     

Predictive models reduce talent development costs in female gymnastics

This retrospective study focuses on the comparison of different predictive models based on the results of a talent identification test battery for female gymnasts. We studied to what extent these models have the potential to optimise selection procedures, and at the same time reduce talent development costs in female artistic gymnastics. The dropout rate of 243 female elite gymnasts was investigated, 5 years past talent selection, using linear (discriminant analysis) and non-linear predictive models (Kohonen feature maps and multilayer perceptron). The coaches classified 51.9% of the participants correct. Discriminant analysis improved the correct classification to 71.6% while the non-linear technique of Kohonen feature maps reached 73.7% correctness. Application of the multilayer perceptron even classified 79.8% of the gymnasts correctly. The combination of different predictive models for talent selection can avoid deselection of high-potential female gymnasts. The selection procedure based upon the different statistical analyses results in decrease of 33.3% of cost because the pool of selected athletes can be reduced to 92 instead of 138 gymnasts (as selected by the coaches). Reduction of the costs allows the limited resources to be fully invested in the high-potential athletes.     

Sex-specific response strategies in mental rotation

The present study investigated whether the marked sex difference in the original mental rotation test (MRT) is simply a result of sex differences in response strategies. Thirty-four participants (17 males, 17 females) completed the revised Vandenberg and Kuse MRT [Peters, M., Laeng, B., Latham, K., Jackson, M., Zaiyouna, R., & Richardson, C. (1995). A redrawn Vandenberg & Kuse Mental Rotations Tests: Different versions and factors that affect performance. Brain and Cognition, 28, 39–58.] and a modified MRT. In the modified version, the number of matching figures varied from zero to four, so that participants had to match every single figure to the target, impeding leaps. Both men and women showed reduced performance in the modified version. However, men were clearly more affected than women. Although sex differences in the modified MRT were somewhat reduced, men still outperformed women (original MRT: d = .95, modified MRT: d = .76). The findings suggest that men rely more on a leaping response strategy than women, however, the robust sex differences in MRT was only marginally affected by sex differences in response strategies.     

Perspektivenübernahme als Kompetenz für den Geschichtsunterricht

This study addresses a competency of students’ historical thinking related to taking perspectives. We start by discussing socio-cognitive theories from psychology as well as approaches from history education that focus on this competency. We also present empirical findings concerning relationships between achievement, self-concept and interest in the subject of history and connect these findings with the competency to take historical perspectives. Our research questions target this relationship between indicators of achievement and motivation in the subject of history, the competency of historical perspective taking and students’ socio-cognitive ability to adopt social perspectives in their everyday lives. These questions are investigated using a cross-sectional design with 375 grammar school students in grades 7 and 10. Results indicate that in grade 7 the competency to take historical perspectives relates to students’ ability to coordinate social perspectives in their everyday lives. For 10th graders, however, the adoption of historical perspectives is closely related to subject-specific variables such as interest for history, self-concept, history grade and achievement in a test of historical knowledge. In the last section of this paper, we discuss challenges that arise when students’ competencies in a subject like history are assessed within the context of standard-based testing. Specifically, we raise the issues of reliability, validity, the context-specificity of measurements, the kinds of response formats used and the formulation of progression models of historical thinking.     

Teachers as mediators: an exploration of situated English teaching

Within the context of lower secondary English teaching in South West England, this study identifies in broad terms the competing goals between which English teachers mediate and the explicit and hidden tensions that result. To understand the interactions of competing goals, teachers' goal‐oriented behaviours are referenced to a set of idealised ‘role types’ based on the dimensions of goals, norms, discourses and practices. It is asserted that competing goals, significant to particular educational circumstances, emanate from various sometimes contradictory local, national and perhaps broader social and cultural influences on practice. Yet the teachers observed moved smoothly between goal‐oriented behaviours in a continuous and comfortable style, easily and without reflecting any tensions between them. Thus, this article elaborates an account of situated English teaching.     

Issues and challenges of teaching and learning in 3D virtual worlds: real life case studies

We aimed to study the characteristics and usage patterns of 3D virtual worlds in the context of teaching and learning. To achieve this, we organised a full‐day workshop to explore, discuss and investigate the educational use of 3D virtual worlds. Thirty participants took part in the workshop. All conversations were recorded and transcribed for analysis. Thematic analysis was carried out to identify prominent issues and topics. We found that to fully utilise 3D virtual worlds for teaching and learning, students, tutors and educational institutions face a number of socio‐psychological, pedagogical and technological challenges. The paper highlights and discusses the issues that emerged from the workshop, supporting them with real life experiences and case studies provided by the workshop participants.

Probleme und Herausforderungen des Unterrichtens und Lernens in virtuellen 3D Welten: “echte” Lebensfallstudien

Wir hatten zum Ziel, die Eigenschaften und die Gebrauchsweise von 3D‐virtuellen Welten im Zusammenhang mit Unterricht und Lernen zu studieren. Dazu organisierten wir einen ganztägigen Workshop, um den Gebrauch von 3D virtuellen Welten im Bildungsbereich zu erforschen, zu besprechen und zu untersuchen. Dreißig Teilnehmer nahmen an diesem Workshop teil. Alle Gespräche wurden aufgezeichnet und für die Analyse transskribiert. Eine thematische Analyse wurde ausgeführt, um gängige Probleme und Themen herauszufinden. Wir meinen, dass, um virtuelle 3D‐Welten komplett zu verwerten, um darin zu unterrichten und Erfahrungen zu sammeln, Studenten, Tutoren und Bildungseinrichtungen mehreren sozialpsychologischen, pädagogischen und technologischen Herausforderungen gegenüberstehen. Dieser Beitrag beleuchtet und bespricht die Probleme, die innerhalb des Workshops auftauchten und unterstützt ihr Verständnis durch von den Workshopteilnehmern selbst zur Verfügung gestellten Lebenserfahrungen und Fallstudien.

Problèmes et défis de l’enseignement/apprentissage dans des mondes virtuels en 3D: des études de cas empruntés à la vie réelle

Nous avions pour but d’étudier les caractéristiques et les schémas d’usage des mondes virtuels en 3D dans un contexte d’enseignement et apprentissage. Pour y parvenir, nous avons organisé un atelier d’une journée entière pour débattre, explorer et mener une recherche sur l’emploi éducatif des mondes virtuels en 3D. L’atelier a accueilli 30 participants. Toutes les conversations ont été enregistrées et transcrites à des fins d’analyse. On a effectué une analyse thématique pour identifier les problèmes et les thèmes les plus marquants. Nous avons découvert que pour utiliser à fond les mondes virtuels en 3D pour l’enseignement et l’apprentissage, les étudiants, les tuteurs et les institutions éducatives doivent faire face à un certain nombre de défis socio‐psychologiques, pédagogiques et technologiques. Dans cet article l’accent et le débat portent sur les questions qui sont apparues au cours de l’atelier, le tout appuyé sur des expériences de la vie réelle et sur des études de cas fournies par les participants à l’atelier.

The enrichment triad model for the very young gifted

The article describes why the Enrichment Triad Model needs to be adapted for a preschool/primary setting and provides suggestions for educators on how to do this. A real‐life example of a five‐year‐old who successfully completed a Type III project is presented. The role of the teacher in understanding how a young child's differences in social, physical, academic, and emotional development can influence appropriate programming is emphasized.     

Familie, Peers und Bildungsungleichheit. Qualitative Befunde zur interdependenten Bildungsbedeutsamkeit außerschulischer Bildungsorte

This article presents the results of a qualitative triangulation study which explored the development of educational inequality from the perspective of 13-year-olds, their parents and their friends. The article offers new empirical insights into the interaction of the family and peer settings and their importance for the educational biography of pupils aged about 13 and the development of educational inequality. First of all, the requirements for educational research into non-school settings are discussed. Then, the hitherto largely unconnected fields of research into educational biographies, families and peer settings are examined to ascertain how they could contribute to the goal of a qualitative triangulation study. This is followed by a presentation of the questions and the conceptual and empirical methods of our own study, before the results are presented in the form of a typology of the interrelationships. The article concludes with a discussion of the results against the background of the goals formulated at the beginning of the article and considerations about research into the social origins of habitus.
