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

The premise of a great deal of current research guiding policy development has been that accommodations are the catalyst for student performance differences. Rather than accepting this premise, two studies were conducted to investigate the influence of extended time and content knowledge on the performance of ninth‐grade students who took a statewide mathematics test with and without accommodations. Each study involved 1,250 accommodated students (extended time only) with learning disabilities and 1,250 nonaccommodated students demonstrating no disabilities. In Study One, a standard differential item functioning (DIF) analysis illustrated that the usual approach to studying the effects of accommodations contributes little to our understanding of the reason for performance differences across students. Next, a mixture item response theory DIF model was used to explore the most likely cause(s) for performance differences across the population. The results from both studies suggest that students for whom items were functioning differently were not accurately characterized by their accommodation status but rather by their content knowledge. That is, knowing students' accommodation status (i.e., accommodated or nonaccommodated) contributed little to understanding why accommodated and nonaccommodated students differed in their test performance. Rather, the data would suggest that a more likely explanation is that mathematics competency differentiated the groups of student learners regardless of their accommodation and/or reading levels. 相似文献

Like most things that we take for granted, we rarely pay attention to ethical issues in research until something goes horribly wrong. Focusing on a recent cyberresearch project gone awry, this essay illustrates why ethical issues should be continually confronted and discussed by scholars and nonscholars alike. 相似文献

Mixture Rasch models have been used to study a number of psychometric issues such as goodness of fit, response strategy differences, strategy shifts, and multidimensionality. Although these models offer the potential for improving understanding of the latent variables being measured, under some conditions overextraction of latent classes may occur, potentially leading to misinterpretation of results. In this study, a mixture Rasch model was applied to data from a statewide test that was initially calibrated to conform to a 3‐parameter logistic (3PL) model. Results suggested how latent classes could be explained and also suggested that these latent classes might be due to applying a mixture Rasch model to 3PL data. To support this latter conjecture, a simulation study was presented to demonstrate how data generated to fit a one‐class 2‐parameter logistic (2PL) model required more than one class when fit with a mixture Rasch model. 相似文献
