Over recent decades language teaching and learning has undergone a redefinition of the subject and a rapid change in its methodology. Language programmes can now be delivered in technology‐based environments and communication at an international level can be a daily occurrence. This paper on the one hand analyses how these developments have extended and challenged the traditional roles and responsibilities of language teachers. On the other, it examines to what extent established models of language teacher education acknowledge and address the needs of language teachers today, in particular in relation to the integration of the intercultural dimension into language teaching and learning.
Au cours des récentes décennies l'enseignement–apprentissage des langues s'est vu redéfini et a connu une rapide évolution en matière de méthodologie. On peut aujourd'hui délivrer les cursus de langue par le moyen d'environnements technologiques, et il est devenu banal de communiquer internationalement de cette façon. Dans la présente étude nous cherchons d'une part à cerner les défis que présente cette évolution pour les rôles et responsabilités traditionnels des enseignants de langue. D'autre part nous demandons dans quelle mesure les modèles en vigueur en matière de formation des enseignants reconnaissent les nouveaux besoins de ceux‐ci, notamment en ce qui concerne l'intégration de la dimension interculturelle dans leur pratique.
Im Bereich Sprachenlehren und lernen haben sich in den letzten Jahrzehnten grundlegende Veränderungen ergeben, vor allem im Hinblick auf Methodologie. Sprachkurse können jetzt per Computer zu den Adressaten gebracht werden und Kommunikation über Grenzen hinweg wird potentiell zum alltäglichen Ereignis. Hier soll untersucht werden inwieweit diese Entwicklungen die traditionelle Rolle und den Verantwortungsbereich von Sprachenlehrer/innen erweitert und verändert haben. Darüberhinaus wird überprüft inwieweit die herkömmliche Ausbildung der Sprachenlehrer/innen den heutigen Anforderungen gerecht wird, vor allem im Hinblick auf die interkulturelle Dimension des Lehren und Lernens von Fremd‐ und Zweitsprachen.

Traditionally, and from a Humboltian perspective, research was conceived as an important part of the tripartite mission of universities, with teaching and services to the community being the other two. The traditional idea of universities as cultural and social institutions is increasingly being replaced by another: the entrepreneurial, capitalist or, even, industrial university. In the new university, research also changes in line with the economic instrumentality of higher education. In this article, we shall analyse if these new ideas were institutionalised in Portuguese public universities. To do this, we analyse the way in which research is signified in communication processes by analysing the content of universities' websites. In the main webpages, the dominant implicit social meaning of research seems to be a traditional one. However, a more specific analysis reveals the presence of entrepreneurial elements. In Portuguese public universities, creating and commercialising intellectual property could be an institutional objective, but it was not used in the web communication as such. One could say that, despite the New Public Management influences on universities, the idea of research as an entrepreneurial issue was not yet completely institutionalised and, consequently, communication tools such as websites showed hybrid meanings of research. 相似文献
We present a proposal for helping students to cope with statistical word problems related to the classification of different cases of confidence intervals. The proposal promotes an environment where students can explicitly discuss the reasons underlying their classification of cases. 相似文献
Spinal cord injury (SCI) derives in loss of bone mineral content (BMC) and bone mineral density (BMD). However, physical activity is an important determinant in bone mass acquisition, which is partially mediated through the lean mass (LM). The aim was to examine the effect of cardiorespiratory fitness (CRF) on BMD and BMC arms of adult males with SCI and able-bodied controls using the arm LM as a mediator variable. Thirty able-bodied men and thirty men with SCI participated. BMC and BMD were analysed by DXA, and indirect calorimetry was used to calculate VO2peak during a progressive arm-cranking test. When groups were divided by the amount of LM, the subgroup with highest LM had significantly higher arm BMC compared to the lowest LM subgroup (p ≤ 0.05) in both SCI and able-bodied groups. Moreover, same differences were found when confidence intervals were analysed. Only in the SCI group, arm LM mediated the relationship between bone mass and CRF at 30.9%, as indicated by the Sobel test (z = 2.17 and z = 2.04 for BMC and BMD, respectively). In conclusion, LM mediates the indirect association between CRF and bone health, specifically in the arms. This finding highlights the importance of having an adequate CRF for the maintenance of good bone health in SCI men. 相似文献
The purpose of this study was to determine the foot strike patterns (FSP), rearfoot position at initial contact (RPic, i.e., No INV/EVE) and foot rotation in children in relation to age. A total of 932 children aged 3 to 16 years participated in this study. A sagittal and frontal-plane video was recorded using a high-speed camcorder to analyse these variables. There is a significant increase (p < 0.001) of rearfoot strike patterns (RFS) prevalence in relation to age; e.g. preschool children (3–6 years old) displayed an RFS prevalence 46.65% and the adolescent population(15–16 years old) an RFS prevalence 92.20%. The total RFS prevalence in all samples was 69.25%. There was a significant reduction (p < 0.001) of prevalence of RPic in relation to age groups; preschool children displayed a prevalence of RPic 60.37% and the adolescent population 10%. There was a significant reduction (p < 0.001) of prevalence of no foot rotation in relation to age groups; preschool children displayed a prevalence of no foot rotation 48.95% and the adolescent population 13.55%. In conclusion, FSP in children are influenced by age. It is noteworthy that the RFS prevalence of children is lower in comparison to the adult population. 相似文献
The aim of this study was to quantify the impact of selections and shared selections in the rugby union. Players’ names, positions, and number of selections were collected for all XV de France’s games (1906–2014). Every team’s percentage of renewal of workforce was calculated for backs and forwards. During the 1987–2014 period, all second row forwards (locks), halfbacks, and centres’ shared selections (number of times when two players have competed together) were recreated. The Best vs. Rest method was applied to these remodelled dyads. They were analysed and compared with surrounding teammates as well as opponents. Head coaches similarly change their workforce for upcoming matches after winning or losing (around 30%), but losing teams renew significantly more positions in their line-ups. The recreated halfbacks, locks, and centres reveal a common pattern. Whether victorious or not, the ‘renewed couples’ victory percentage will congregate towards the XV de France’s victory percentage. For all the best recreated couples, the cumulated number of selections for forwards’ is always higher than the ones part of less efficient teams: 231.3?±?80 vs. 212.9?±?91 selections for locks’ teammates (Effect sizes (ES) small, possibly positive, 54.8%). In best recreated couples, number 8’s are significantly more experienced than their counterparts in less efficient pairs (ES small, likely positive, 76.3%). The XV de France’s collective effectiveness relies on a balance between stability and workforce renewal, which allows the building of specific position interactions and builds on experimented forwards packs. Selections and shared selections are serious collective performance parameters associated with performance. 相似文献
The effects of exercise on the core musculature have not been investigated in prepubescents. The main purpose of the present study was to determine the volume and degree of asymmetry of rectus abdominis, obliques and transversus abdominis, quadratus lumborum, iliopsoas, gluteus and paravertebralis muscles in prepubescent tennis players and in untrained boys. The muscle volume was determined using magnetic resonance imaging (MRI) in 7 male prepubescent tennis players and 10 untrained controls (mean age 11.0 ± 0.8 years, Tanner 1–2). After accounting for height and body weight as covariates, the tennis players had 14–34% greater volume than the controls in all the muscles analysed (P < 0.05) except in paravertebralis, dominant quadratus lumborum and non-dominant gluteus, which had similar volumes in both groups (P = NS). Compared to controls, the tennis players displayed a greater degree of asymmetry in quadratus lumborum and rectus abdominis (3% vs. 15%, P < 0.01 and 8% vs. 17%, P = 0.06, respectively). The level of asymmetry of obliques and transversus abdominis, iliopsoas, gluteus and paravertebralis muscles was similar in both groups (P = NS). In conclusion, tennis playing at prepubertal ages induces a selective hypertrophy of the core musculature and exaggerates the degree of asymmetry of quadratus lumborum and rectus abdominis compared to untrained boys. 相似文献
