This paper discusses the professional development of primary modern language teachers through the use of new technologies. It explores the principles upon which the development of a multimedia learning environment (FLiP – Foreign Languages in Primary) was constructed. These entail principles of effective modern‐language teaching, principles of teacher education, and a conception of the effective teacher. In addition, ways in which technology can support the principles of effective professional development are discussed. Information technology can be extremely empowering, extremely motivating and extremely conducive to creating new and exciting teacher‐education environments. The most outstanding contribution is that multimedia environments can make teachers look beyond the immediate context thanks to the incorporation of indirect observation.Les multimédias dans la formation des enseignants en langues étrangères. Cet article discute le d´eveloppement professionnel des enseignants du primaire en langues modernes, grâce à l'utilisation des nouvelles technologies. Il explore les principes selon lesquels le développement d'un environnement multimédia a été construit (FLIP - Foreign Languages in Primary). Ils impliquent les principes de l'enseignement efficace des langues modernes, les principes de la formation des maîtres, et une conception du maître efficace. De plus, les façons dont la technologie vont soutenir les principes d'un développement efficace sont discutées. La technologie de l'information peut être très puissante, très motivante pour créer des nouveaux environnements excitants pour la formation des maîtres. La plus importante contribution est que les environnement mulitimédia amènent les maîtres à regarder au delà du contexte immédiat grâce à l'incorporation de l'observation indirecte.Multimedia in der Ausbildung von Lehrern für neue Sprachen. Dieses Papier erörtert die professionelle Entwicklung von Material zur Ausbildung von Grundstufenlehrern für moderne Sprachen durch die Verwendung neuer Technologien. Es vermittelt die Prinzipien, auf denen die Entwicklung einer Multimedia Lernumgebung ('FLIP - Foreign Languages in Primary') aufgebaut wurde. Diese enthalten Prinzipien modernen Sprachunterrichts, Prinzipien von Lehrerbildung und ein Konzept des 'wirksamen' Lehrers. Außerdem wird diskutiert, welche Technik die Prinzipien wirksamer professioneller Entwicklung unterstützen kann. Die Nutzung von Informationstechnologie kann extrem verstärkend, extrem motivierend und äußerst dienlich sein, neue und aufregende Möglichkeiten für die Lehrerbildung.zu schaffen. Der hervorragendste Beitrag ist, daß Multimediaumgebungen es Lehrern ermöglichen können, sich öber den unmittelbaren Kontext durch die Integration indirekter Beobachtung zu informieren. 相似文献

Mixed methods research (MMR)—which integrates qualitative and quantitative methods in one study to improve the study's quality—is not common in library and information science (LIS) and has not been discussed in its literature. While still evolving and generating much discussion about its nature and standards for its evaluation, MMR has been employed in the social and behavioral sciences for more than three decades. It is already considered the third approach to research, along with the quantitative and qualitative approaches. How did this approach shape research in LIS? An analysis of 465 articles published in four major LIS research journals revealed that 22 articles (5%) employed MMR. However, the recognition of MMR by name or as a research method was absent from these articles and from the methodological literature in LIS. The various strengths of MMR suggest that being cognizant of its possible use in LIS would benefit researchers in the field. 相似文献

After a latency period, the American cinema is processing the trauma of defeat in the Vietnam War. In these films, defeat is repressed but the defeated male is present. Central to the texts is a profound loss of self, incoherence at the gendered core of masculine identity, the failure to conform to the heteronormative mythical model, loss of traditional affiliations (representability of the social order, fatherhood, brotherhood), tortured body, and shattering of sexuality. All three models of post-traumatic masculinity subvert the identification between masculinity, patriarchy, and nationalism. 相似文献

The whole world is now referred to as a global village because of the technological revolution is taking place especially in the area of information and communication. In this paper, the author started the discussion with definition of communication, highlighted means of communication and purposes of communication, counselling as a form of communication, conceptual flame work for communication in ODL （open and distance education）, component of good communication, media selection and combination for effective counselling process in NOUN. The author in his recommendations, advocated that for a counsellor to be effective in discharging his responsibilities, he or she must attain a certain level of competency in communication skills, select appropriate media, and must be efficient in the use of communication devices especially computer. Also the media of counselling must be readily available to both the counsellor and counselees. 相似文献

In this paper, we investigate the determinants of over-education in Japan and evaluate its opportunity costs for university graduates. To this end, we use the REFLEX data. Results reveal that over-education level in Japan is high and it brings an important wage penalty for Japanese workers. Large firm and high occupations point toward a significant reduction in the likelihood of over-education. Results for wage regressions for over-education indicate that Japanese workers who achieve jobs in large organizations will experience 20 % increase in their wage due to the firm size and, if over-educated, their increase in wage will remain positive. Results for women are puzzling as there is no significant effect associated with gender. 相似文献

Collaborative filtering is a popular recommendation technique. Although researchers have focused on the accuracy of the recommendations, real applications also need efficient algorithms. An index structure can be used to store the rating matrix and compute recommendations very fast. In this paper we study how compression techniques can reduce the size of this index structure and, at the same time, speed up recommendations. We show how coding techniques commonly used in Information Retrieval can be effectively applied to collaborative filtering, reducing the matrix size up to 75 %, and almost doubling the recommendation speed. Additionally, we propose a novel identifier reassignment technique, that achieves high compression rates, reducing by 40 % the size of an already compressed matrix. It is a very simple approach based on assigning the smallest identifiers to the items and users with the highest number of ratings, and it can be efficiently computed using a two pass indexing. The usage of the proposed compression techniques can significantly reduce the storage and time costs of recommender systems, which are two important factors in many real applications. 相似文献

There are practical difficulties in making intercultural education a substantial element of inclusion in both primary and compulsory secondary education in Europe. The Spanish education system and, in particular, the Catalan education system, have developed a series of strategies in response to the new multicultural complexity encountered in both the classroom and society as a whole. In this study, several inclusive attempts of the Catalan education system will be discussed. As a consequence of their analysis, educational models that are compatible with the framework of inclusive education will be presented as an effective means of promoting greater social integration and a peaceful coexistence in the school context. 相似文献

The increasing number of documents that have to be indexed in different environments, particularly on the Web, and the lack of scalability of a single centralised index lead to the use of distributed information retrieval systems to effectively search for and locate the required information. In this study, we present several improvements over the two main bottlenecks in a distributed information retrieval system (the network and the brokers). We extend a simulation network model in order to represent a switched network. The new simulation model is validated by comparing the estimated response times with those obtained using a real system. We show that the use of a switched network reduces the saturation of the interconnection network, especially in a replicated system, and some improvements may be achieved using multicast messages and faster connections with the brokers. We also demonstrate that reducing the partial results sets will improve the response time of a distributed system by 53%, with a negligible probability of changing the system’s precision and recall values. Finally, we present a simple hierarchical distributed broker model that will reduce the response times for a distributed system by 55%. 相似文献
