There is growing concern that almost 20 years after the 1988 Education Act, top‐down, large‐scale reform has stalled. The policy mix of choice, competition, markets, regulation, accountability and leadership seems not to have closed the gap between advantaged and disadvantaged areas and individuals, while most variations in school performance can be explained in terms of intake differences. This paper reviews policy and progress since 1988 and assesses the extent to which central government has achieved its educational aims. Unacknowledged tensions and contradictions are identified in structures and practices that are supposed to constitute a reliable framework for sustainable improvement. The conclusion is drawn that since 1988 the national government apparatus has itself become an important obstacle to further progress. An independent review of policy‐making and implementation is recommended so that schools and colleges are enabled to contribute more effectively to improvements in the quality of education.  相似文献

Recogito 2 is an open source annotation tool currently under development by Pelagios, an international initiative aimed at facilitating better linkages between online resources documenting the past. With Recogito 2, we aim to provide an environment for efficient semantic annotation—i.e., the task of enriching content with references to controlled vocabularies—in order to facilitate links between online data. At the same time, we address a perceived gap in the performance of existing tools, by emphasizing the development of mechanisms for manual intervention and editorial control that support the curation of quality data. While Recogito 2 provides an online workspace for general-purpose document annotation, it is particularly well-suited for geo-annotation, in other words annotating documents with references to gazetteers, and supports the annotation of both texts and images (i.e., digitized maps). Already available for testing at http://recogito.pelagios.org, its formal release to the public occurred in December 2016.  相似文献

Audience research, after a promising period during which some crucial advances were made, seems to be in decline in several ways, yet its tasks remain as important as ever. This article, originally a presentation at the 2003 Versailles Conference on the Future of Audience Research, makes the case for expanding our vision of the field’s possibilities. To do this, it revisits some of the forgotten achievements of the Uses and Gratifications tradition, offers a critique of the dominant “Hall model” for conceiving media/audience relations, and outlines the key concept of an alternative approach: the concept of a “viewing strategy,” which has been at the heart of the 2003–2004 international project on the reception of The Lord of the Rings.  相似文献

A longitudinal study of 250 students following the Salters Advanced Chemistry (SAC) course probed a range of chemical ideas including the exothermicity of bond formation and the development of thinking about covalent, ionic and intermolecular bonds. Students responded to the same diagnostic questions on three occasions: at the start, after eight months and sixteen months of a twenty-month course. At the start, many students demonstrated misunderstandings about these chemical ideas, but in general their understanding improved as the course progressed. By the end of the study, about half knew that bond making is exothermic. Initially, few described covalent bonds accurately or understood hydrogen bonding. A majority gave responses at the final survey which were in line with ideas and language a chemist may use. Students attributed changes to the use of context-based materials including a drip-feed approach which allowed their understanding to develop over time. However, some aspects of chemical bonding, including ionic bonding and intermolecular bonds other than hydrogen bonds remained problematic for students despite explicit teaching. The findings have implications for post-16 chemistry teaching, suggesting that a review of teaching strategies is needed in some areas.  相似文献
