Current government policy in the UK places teachers of all subject areas under pressure to embed ICT into their pedagogic practice to improve teaching and learning. This article attempts to compare that policy with the situated reality of a small number of Modern Foreign Language teachers striving to comply. The voices of four teachers are presented as they began to embed the use of ICT (primarily their newly acquired Interactive Whiteboards) into their existing classroom approach. The story of their developing practice is examined for signs of transformation; the complexity of a real situation is thus contrasted with a simplified ideal. By means of this investigation, examples of sophisticated pedagogical thinking are explored to demonstrate that it is perhaps not so easy to transform the learning process, with or without ICT.

La politique actuelle du gouvernement du Royaume‐Uni exerce une pression sur les enseignants de toutes matières pour qu'ils intègrent les technologies d'information et de communication dans leurs pratiques pédagogiques afin d'améliorer l'enseignement et l'apprentissage. Cet article essaye de comparer cette politique avec la réalité contextualisée d'un petit nombre de professeurs de langues étrangères qui font leur possible pour s'y conformer. Les voix de quatre enseignants y sont présentées alors qu'ils commençaient à intégrer l'informatique (et en particulier leurs tableaux interactifs récemment acquis) dans leur approche pédagogique actuelle. L'histoire du changement de leurs pratiques est remise en question pour trouver des indications de transformation. La complexité d'une situation réelle peut alors être mise en contraste avec une idée simplifiée. De par cette étude, on peut examiner des exemples de la réflexion pédagogique développée pour montrer que ce n'est pas tellement facile de transformer les méthodes d'apprentissage, avec ou sans l'outil informatique.

Die Gegenwärtige Regierungspolitik in Großbritannien setzt Lehrkräfte aller Schulfächer unter Druck, moderne Informationstechniken in ihre pädagogische Praxis einzubeziehen, um den Unterricht und den Lernprozess zu verbessern. Dieser Beitrag versucht, diese Politik mit der realen Situation einer kleinen Anzahl von SprachlehrerInnen zu vergleichen, die sich bemühen, den Anordnungen nachzukommen. Die Stimmen von vier Lehrkräften werden vorgelegt, die damit begonnen haben, Informations‐ und Kommunikationstechnologie (hauptsächlich ihre neu erworbenen interactive whiteboards (interaktive Tafeln)) in ihre gegenwärtige Unterrichtsmethode einzubeziehen. Es wird untersucht, welche Veränderungen es bei zunehmender Praxis gibt. Die Vielschichtigkeit einer realen Situation wird somit dem vereinfachten Idealfall gegenübergestellt. Mittels dieser Untersuchung werden Beispiele hochentwickelten pädagogischen Denkens erforscht und dazu verwendet, um zu zeigen, dass es doch nicht so einfach ist, den Lernprozess zu verändern—mit oder ohne ICT.

La política actuel del gobierno del Reino Unido sitúa a los profesores de todos los departamentos bajo la presión de arraigar ICT en la práctica de su pedagogía para mejorar la enseñanza y el aprendizaje. Este artículo intenta comparar esa política con la realidad de un pequeño número de profesores de idiomas extranjeros que se esfuerza por llevarla a cabo. La voz de cuatro profesores nos presenta como empoezaron a arraigar el uso de ICT (primeramente con la reciente adquisición de los Whiteboards Interactivos) como enfoque en sus clases actuales. La historia de su práctica en desarrollo está acompañada de indicios de cambios. Por eso la complejidad de una situación real se contrasta con un ideal más simplificado. Por medio de esta investigación, se exploran ejemplos de pensamiento pedagógico sofisticado para demostrar que quizás no sea tan fácil transformar el proceso de aprendizaje, con o sin ICT.  相似文献

The objective of the investigation was to study the application of ultrasound reactor technology (USRT) as a disinfectant for reduction of fungi from sewage effluent. Fungi are carbon heterotrophs that require preformed organic compounds as carbon sources. USRT is an attractive means to improve water quality because of the system simplicity and no production of toxic by-products. An ultrasound reactor produces strong cavitation in aqueous solution causing shock waves and reactive free radicals by the violent collapse of the cavitation bubble. These effects should contribute to the physical disruption of microbial structures and inactivation of organisms. There was significant reduction in fungal growth, with decreased fungal growth with increasing USRT. In this study, ultrasound irradiation at a frequency of 42 kHz was used to expose suspensions of fungi to evaluate the disinfection efficacy of the ultrasound reactor. Also, this study showed that in this system more than 99% reduction of sewage fungi was achieved after 60 min.  相似文献

While researchers with retracted papers – publications that are withdrawn because of significant errors or scientific misconduct – carry a permanent stain on their publishing records, understanding the causes and initiators of such retractions can shed a different light on the matter. This paper, based on a random sample of 2,046 retracted papers, which were published between 1975 and 2019, extracted from Retraction Watch and the websites of major publishers, shows that 53% of the retraction notices do not specify who initiated the retraction. Nearly 10% of the retraction notes either omit or do not contain information related to reasons for retractions. Furthermore, most of the retracted papers in our sample have no limitation section; those who do are commonly unhelpful or irrelevant. The results carry three implications for scientific transparency: retraction notices need to be more informative; limitation sections ought to be a required and even an open section of all published articles; and finally, promoting ‘heroic acts’ in science can positively change the current publishing culture.  相似文献

This article presents the results of a study evaluating a program to help museum docents improve accessibility for visitors with communication challenges (such as hearing, language and/or speech disorders). This was done by adapting docent presentations. The docents' speech patterns were evaluated before and after a training program, and showed significant improvements in the rate, duration, and use of pauses in their speech. There also was significant improvement in ensuring that view of their faces remained unobstructed—important for people with communication disorders—in order to facilitate the consistent visibility of their facial expressions and visual cues. The training was found to be effective in adjusting the docents' presentations so that the museum experience would be improved for visitors with communication challenges.  相似文献

The primary goal of this research is to better understand my students' reading orientations – what they believe it means to be a successful reader. I also seek to identify the relationship between those beliefs and my teaching. The data come primarily from six focal students in my second-grade classroom in an urban public charter elementary school in Oakland, California. Focal students were observed, interviewed, and asked to discuss and rank vignettes of readers with varying reading behaviors, skills, and habits. In addition, I drew on systematic reflections about my own teaching and students. Results showed that focal students shared reading orientations toward aspects of fluency, such as accuracy, and knowledge-level comprehension skills, such as retelling events from a story. Results also showed that students' responses correlated closely with teaching points emphasized both within my classroom and around the school. These results, in combination with data from observations, led me to discover that students' reading orientations may have both public and private aspects. In other words, their stated preferences might differ from their private inclinations. These findings suggest that teachers need to be organized and intentional around the messages that they send to students about successful reading. They also suggest that teachers create environments in which various purposes and reading behaviors are valued.  相似文献
