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.

En las últimas décadas la enseñanza y el aprendizaje de las lenguas ha pasado por una redefinición de su contenido y un rápido cambio en su metodología. Los programas de estudios se pueden realizar en entornos basados en las nuevas tecnologías y la comunicación a nivel internacional puede darse a diario. Este artículo de una parte analiza de qué manera estos cambios han ampliado y desafiado los papeles y las responsabilidades que los profesores de lenguas han tenido tradicionalmente. De otra parte, examina hasta qué punto los modelos que se han venido utilizando para la formación de profesores de idiomas reconocen y suplen sus necesidades en la actualidad, en particular en lo que se refiere a la integración de la dimensión intercultural en la enseñanza y el aprendizaje de las lenguas.  相似文献

To better understand the information needs of young university researchers, an observational study was performed at three universities in Stockholm, Sweden. The observations revealed that most of the researchers used Google for everything, that they were confident that they could manage on their own, and that they relied heavily on immediate access to electronic information. They had very little contact with the library, and little knowledge about the value librarian competence could add. One important conclusion of the project is that librarians have to leave the library building and start working in the research environment, as well as putting some thought into the fact that library use is considered complicated, but Google (etc.) is easy. The findings of this project will influence changes in library services in both near and in a more distant future.  相似文献

In part one of this paper, Stoszkowski and Collins showed that shared online blogs were a useful tool to structure and support the informal learning of a cohort of final year undergraduate sports coaching students. The aim of the present study was to offer insight into student coaches' perceptions of their use and experiences of structured group blogging for reflection and learning. Twenty-three student coaches (5 females, 18 males), purposely sampled from the original study, took part in four semi-structured focus group interviews. Interview data were inductively analysed. Student coaches were generally very positive about their learning experiences and the pedagogical approach employed. This was especially apparent in terms of perceived increases in levels of reflection, knowledge acquisition and improvements in coaching practice; changes corroborated by the data presented in part one. A range of reasons emerged for these outcomes, alongside several potential limiters of engagement in shared group blogging as a learning endeavour. Whilst these findings support recent, and growing proposals to systematically incorporate Web 2.0 technologies such as blogs into coach education pedagogy, several key considerations for the process of using such tools are outlined. Finally, the implications for coach educators are discussed.  相似文献

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.  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

Theories of organisation actually become ideologies, legitimisations for certain forms of organisation. They deploy arguments in terms of rationality and efficiency to provide control. The limits that they impose upon the conception of organisations actually close down the possibility of considering alternative forms of organisation. This is nowhere more clearly evident than in the current application of management theories to schools. Such theories marginalise empirical studies of school practice and dismiss the folk‐knowledge’ of teachers as irrelevant. They are as significant for what they exclude as for what they include (Ball, 1987, p. 5).  相似文献

We analyse the utility of social capital for children’s achievement, and if this utility interacts with family human capital and the quality of the parent-child relationship. Our focus is on parental activities directly related to children’s school work. Our data stem from a Swedish cohort born in 1953 and consist of both survey and register data. We find that parents with more human capital tended to offer their children more social capital. OLS regressions showed that, when present, social capital was directly related to children’s grades and its utility for achievement did not depend on parents’ human capital. The utility of social capital was enhanced when combined with a very good parent-child relation.  相似文献
